Xiamen Subang Technology Co., Ltd. – Your trusted partner in high-pressure gas storage.

If you’re serious about PCP air rifles, paintball, or scuba diving, you already know that a reliable high-pressure air source isn’t optional—it’s essential. The TUXING double-cylinder air compressor has been engineered to deliver exactly that: consistent, high-pressure air in a package that’s built for real-world use, whether you’re at home, in the garage, or out in the field.

Why Double-Cylinder Design Matters

At the heart of this compressor is a dual-cylinder system powered by a robust 800W motor (with some models featuring a 2.2kW copper motor). Compared to single-cylinder alternatives, the double-cylinder configuration doubles the airflow and significantly reduces fill times. For example, this compressor can fill a 1-liter compressed air bottle from 0 to 300 bar in just about 11 minutes—a level of speed that makes a tangible difference when you’re prepping for a dive or a shooting session.

The air output reaches up to 40–50L/min depending on the model, which means less waiting and more doing.

Dual Voltage: 110V and 220V Compatibility

One of the most practical features of this TUXING compressor is its voltage adaptability. It supports both 110V and 220V power supplies, making it suitable for use in North America, Europe, Asia, and beyond. Whether you’re plugging into a standard household outlet in the US or a 220V socket in Europe, you won’t need to worry about voltage mismatches or bulky converters. This flexibility makes the compressor a genuinely global tool.

Intelligent Safety and Automation

High-pressure compressors demand safety features that actually work. This unit includes:

Automatic Shut-Off: Once the preset pressure is reached, the compressor powers down automatically. This prevents over-inflation, saves energy, and extends the lifespan of both the compressor and the equipment being filled.

Automatic Air Release (Auto Purge): The built-in auto purge function releases excess pressure when needed, maintaining optimal pressure levels and protecting sensitive components from damage due to over-pressurization.

These aren’t just conveniences—they’re safeguards that give you peace of mind during every fill.

Effective Cooling for Extended Operation

Heat is the enemy of any compressor. TUXING addresses this with a dual cooling approach. Depending on the model, you’ll find either an integrated fan cooling system or a combined air-and-water cooling setup. The air-cooling component handles initial heat dissipation, while the water-cooling system (on select models) ensures stable temperatures during prolonged, high-pressure operation. The result is a compressor that maintains peak performance without frequent overheating stops—even under heavy loads.

Some models also feature a built-in two-stage filtration water-oil separator, which purifies the incoming air, traps dust and moisture, and reduces wear on internal parts.

Pressure That Meets Serious Demands

The maximum working pressure reaches 4500 PSI / 30 MPa / 300 Bar. This is the sweet spot for a wide range of high-pressure applications:

• PCP air rifles and airguns: Fast, reliable fills for extended shooting sessions

• Paintball markers: Consistent HPA tank refilling on and off the field

• Scuba diving: Filling small diving cylinders and snorkeling tanks

• Automotive and industrial: Tire inflation, leak detection, pressure testing

• Firefighting and safety equipment: High-pressure air supply for breathing apparatus

Whether you’re a hobbyist, a professional, or someone who simply values having a dependable high-pressure air source on hand, this compressor covers the bases.

Portable Enough to Take Anywhere

Despite its capability, this compressor is designed with portability in mind. Depending on the specific model, weight ranges from around 17kg to 46kg. The lighter versions—like the ultra-portable TXES061-3 at roughly 7kg—can be carried in a backpack or stored in a vehicle trunk. Integrated top carry handles make transport straightforward, so you’re not tied to a fixed workshop location.

Built for Clean, Low-Maintenance Operation

Many TUXING compressors feature an oil-free compression design. This means no regular oil changes, no risk of oil contaminating your air tank, and lower overall maintenance costs. The compressed air delivered is clean and safe for breathing applications and sensitive equipment alike.

OEM and ODM Options for Distributors

For businesses looking to bring high-pressure compressors to their own market, TUXING offers full OEM and ODM services. Customization options include logo printing, color variations, parameter fine-tuning, and packaging adjustments. All products carry CE and ROHS certifications, and the factory maintains strict quality control standards across the production line.

In modern steel construction, C and Z purlins are widely used as secondary structural members for industrial buildings, warehouses, workshops, commercial buildings, and prefabricated steel structures. As construction projects increasingly demand higher efficiency, dimensional accuracy, and flexible production, the CZ purlin roll forming machine has become an important piece of equipment for steel structure manufacturers.

What Is a CZ Purlin Roll Forming Machine?

A CZ purlin roll forming machine is designed to produce C-shaped and Z-shaped steel purlins from galvanized steel or other suitable metal coils.

Compared with traditional production methods, an automatic CZ purlin machine integrates several processes into one production line, including:

• Coil feeding

• Leveling

• Roll forming

• Hydraulic punching

• Length measurement

• Cutting

• Automatic control

Depending on the machine configuration, one production line can manufacture different sizes of C and Z purlins by adjusting the forming system.

This makes the machine especially suitable for factories that need to serve different steel building projects.

Why Are C and Z Purlins So Widely Used?

C and Z purlins combine relatively low weight with good structural strength.

They are commonly used for:

• Roof purlins

• Wall girts

• Steel warehouses

• Industrial workshops

• Agricultural buildings

• Prefabricated buildings

• Commercial steel structures

• Solar mounting structures

C purlins are often used for shorter spans or simple structural applications, while Z purlins are particularly suitable for overlapping connections and continuous-span roofing systems.

Because different building designs require different section dimensions, flexible purlin production has become increasingly important for manufacturers.

Advantages of an Automatic CZ Purlin Machine

1. C and Z Profiles on One Production Line

One of the biggest advantages of a CZ purlin machine is its ability to produce both C and Z profiles.

Instead of purchasing separate production lines, manufacturers can use one machine to meet multiple production requirements.

This reduces equipment investment and saves factory space.

2. Automatic Size Adjustment

Traditional purlin machines often require operators to manually change spacers, rollers, or other components when producing a different size.

Modern automatic CZ purlin machines can significantly simplify this process.

Operators can enter the required dimensions through the PLC control system, and the machine adjusts the forming parameters accordingly.

This is especially useful for factories producing many different specifications every day.

3. High Production Accuracy

Roll forming equipment uses a continuous forming process to gradually shape the steel strip.

With properly designed rollers and an accurate control system, the machine can maintain stable section dimensions and consistent product quality.

Accurate purlins help improve installation efficiency on the construction site and reduce problems during steel structure assembly.

4. Higher Production Efficiency

Automatic feeding, punching, forming, and cutting allow continuous production with limited manual intervention.

Compared with manual fabrication or semi-automatic production, an automatic purlin line can significantly improve productivity.

For manufacturers handling large steel structure orders, production efficiency directly affects project delivery time and overall manufacturing cost.

Typical Material and Production Requirements

CZ purlin machines can be customized according to different project requirements.

Common parameters include:

Material: galvanized steel, cold-rolled steel, or other suitable structural steel

Profile: C purlin and Z purlin

Thickness: customized according to the required machine design

Width and height: adjustable within the designed production range

Punching: available according to customer drawings

Cutting: hydraulic cutting or other suitable cutting systems

Before selecting a machine, buyers should confirm the required profile drawings, material thickness, steel grade, production speed, punching requirements, and local electrical standard.

How to Choose the Right CZ Purlin Roll Forming Machine

When evaluating a CZ purlin machine, price should not be the only factor.

Buyers should also consider:

Profile Range

Confirm the minimum and maximum dimensions that the machine can produce.

A wider production range gives manufacturers greater flexibility when accepting different projects.

Material Thickness

The forming system, transmission system, shafts, rollers, and motor power must match the required material thickness.

A machine designed for light-gauge material may not be suitable for heavier structural sections.

Automatic Changeover

For factories producing different sizes frequently, automatic size adjustment can save considerable setup time.

Punching Requirements

Different construction systems may require different hole positions.

The punching system should therefore be designed according to the actual application.

Electrical Standard

Voltage, frequency, and phase configuration should match the customer's local industrial power supply.

After-Sales Support

Installation support, operating instructions, spare parts, troubleshooting, and technical communication are also important when purchasing industrial machinery from overseas suppliers.

Cold rolling is usually done using the longitudinal rolling method. The processes involved in cold rolling production generally include raw material preparation, pickling, rolling, degreasing, annealing (heat treatment), and finishing. Cold rolling uses hot rolled products as raw materials, and the raw materials must be phosphorus-free before cold rolling to ensure the cleanliness of the cold rolled products' surfaces.

Recently, XHH partnered with a leading infrastructure developer in Southeast Asia for a massive logistics hub project. The client required over 200,000 meters of high-strength Z-purlins delivered within a tight 45-day window.

By deploying two XHH High-Speed CZ Purlin Lines, the client was able to:

1. Meet the deadline 10 days early due to the 30m/min production capability.
2. Reduce labor costs by 60% by utilizing the automatic size adjustment feature, requiring only one operator per line.
3. Ensure 100% assembly accuracy, with zero rejected parts reported during the on-site installation.

In modern steel construction, C and Z purlins are widely used as secondary structural members for industrial buildings, warehouses, workshops, logistics centers, agricultural buildings, and prefabricated structures. Because purlins directly affect the stability, installation efficiency, and overall cost of a steel building, choosing the right C/Z purlin roll forming machine is an important decision for manufacturers and contractors.

A suitable purlin machine should not only produce accurate profiles, but also offer stable production, flexible size adjustment, efficient punching and cutting, and reliable long-term operation. For buyers who are planning to invest in a new production line, understanding the key machine configurations can help reduce unnecessary investment and improve future production efficiency.

1. Understand Your Required Purlin Sizes

The first step in choosing a C/Z purlin roll forming machine is to clearly identify the profile sizes required for your market.

Different construction projects may require different purlin dimensions. Common sizes can range from approximately 100 mm to 300 mm or even larger, depending on the building design and structural load.

For example, smaller profiles are commonly used for light steel buildings, while larger purlins may be required for large-span industrial buildings or heavy-duty structures.

Before purchasing a machine, buyers should confirm several basic parameters:

• Web width

• Flange width

• Lip size

• Steel thickness

• C profile, Z profile, or both

• Required production speed

• Punching hole position

• Cutting length

A machine with a wider production range offers greater flexibility, especially for factories that serve different customers or project types.

2. Automatic C/Z Changeover Can Improve Production Efficiency

Traditional purlin machines may require operators to manually adjust rollers or replace certain machine components when changing from one profile size to another.

For factories that frequently produce different specifications, this process can take significant time and increase labor costs.

Modern automatic C/Z purlin roll forming machines are designed to simplify the adjustment process. With PLC control, operators can input the required dimensions through the touch screen, and the machine can automatically adjust the forming stations according to the production settings.

Some machines can also switch between C and Z profiles without manually replacing rollers.

This type of automatic changeover is particularly useful for manufacturers handling small-batch and multi-size orders.

The main advantages include:

• Reduced machine adjustment time

• Lower labor requirements

• Higher production efficiency

• Better dimensional consistency

• Faster response to customized orders

For companies that produce only one or two fixed sizes, a conventional machine may still be sufficient. However, for manufacturers seeking flexible production, an automatic adjustable machine is usually a better long-term investment.

3. Steel Thickness and Material Strength Are Important

The thickness and strength of the steel coil directly affect the machine structure and forming design.

Common purlin materials include galvanized steel and high-strength structural steel. Depending on the market and application, steel thickness may range from approximately 1.0 mm to 3.0 mm or more.

A machine designed for thin steel may not perform well when continuously processing thicker or higher-strength material.

Therefore, buyers should provide the machine supplier with accurate information about:

• Maximum steel thickness

• Minimum steel thickness

• Material grade

• Yield strength

• Galvanized coating requirements

High-strength steel requires stronger shafts, rollers, transmission systems, and machine frames.

If the machine structure is insufficient, long-term production may lead to dimensional deviation, excessive vibration, roller wear, or forming instability.

For this reason, machine design should always match the real production material rather than only the profile dimensions.

4. Punching System Configuration

Most C/Z purlins require holes for installation and connection.

An integrated hydraulic punching system allows the machine to automatically punch holes according to the programmed production data.

Depending on the customer's project requirements, the punching system can be designed for different hole shapes and positions.

Typical options may include:

• Round holes

• Slotted holes

• Web punching

• Flange punching

• Multiple punching stations

• Customized hole spacing

For projects with repeated specifications, automatic punching can significantly reduce secondary processing.

Instead of forming the purlin first and drilling holes manually afterward, the production line can complete punching, forming, measuring, and cutting in one continuous process.

This improves production efficiency and helps reduce labor errors.

5. Pre-Cutting or Post-Cutting?

Another important machine configuration is the cutting system.

There are generally two common methods: pre-cutting and post-cutting.

A pre-cutting system cuts the steel strip before it enters the forming section. This structure is relatively simple and can reduce the need for multiple cutting dies.

A post-cutting system cuts the finished profile after roll forming. It can provide better control of finished length and is suitable for certain production requirements.

The correct cutting method depends on profile design, production speed, machine structure, and customer requirements.

For adjustable C/Z purlin machines producing multiple sizes, the supplier should carefully design the cutting system to ensure clean cutting edges and consistent finished dimensions.

6. PLC Control and Automatic Production

A modern purlin roll forming line should have an easy-to-use PLC control system.

Operators can normally enter production information such as:

• Product length

• Required quantity

• Profile size

• Punching position

• Batch information

After the parameters are entered, the machine can perform automatic production according to the program.

The control system can also monitor production quantity and help operators identify basic machine alarms.

A user-friendly control interface can reduce training time and make daily production easier for factory workers.

For overseas customers, English-language control interfaces are usually available, and other languages can also be customized depending on project requirements.

7. Production Speed Should Match Your Actual Demand

Higher speed is not always better.

Some buyers focus heavily on the maximum forming speed when comparing machines. However, the real production efficiency depends on the complete production process, including feeding, punching, forming, cutting, and material handling.

For example, if the forming section operates very quickly but the punching system requires frequent stops, the actual average production speed may still be lower.

Therefore, buyers should evaluate the realistic working speed rather than only the theoretical maximum speed.

For many steel building manufacturers, a stable and reliable production speed is more valuable than extremely high speed.

Stable operation helps reduce:

• Material waste

• Machine downtime

• Dimensional errors

• Maintenance frequency

• Unexpected production interruptions

8. Machine Frame and Roller Quality

The mechanical structure is one of the most important factors affecting machine life.

A strong machine frame helps maintain forming accuracy during long-term operation.

Rollers should also be manufactured with suitable material and precision machining.

Depending on the machine configuration, rollers may receive heat treatment or surface treatment to improve hardness and wear resistance.

Important components such as shafts, bearings, gearboxes, hydraulic systems, and electrical parts should also be selected according to the expected production load.

For buyers, it is useful to compare not only the machine appearance but also the structural design and component specifications.

A heavier and stronger machine is often more suitable for long-term industrial production, especially when processing thicker or higher-strength steel.

9. Customized Production Requirements

Different countries and customers may have different standards and building practices.

For example, purlin sizes used in Australia may be different from those commonly used in Europe, South America, Southeast Asia, or the Middle East.

Some customers may also require customized punching patterns, special flange dimensions, unique profile designs, or additional marking systems.

A professional roll forming machine supplier should be able to design the machine according to the customer's profile drawing and material specifications.

Before production, buyers should provide detailed drawings showing all important dimensions.

This allows the engineering team to confirm the roller design and avoid misunderstandings during machine manufacturing.

10. Installation, Training, and After-Sales Support

A roll forming machine is a long-term industrial investment.

Therefore, after-sales support should also be considered when selecting a supplier.

A reliable supplier should provide technical documents such as:

• Machine operation manual

• Electrical diagrams

• Hydraulic diagrams

• Installation instructions

• Maintenance instructions

• Spare parts information

Remote technical support can help solve many common operating problems quickly.

For more complex projects, overseas installation or technician support may also be available depending on customer requirements.

Before ordering, customers should clearly discuss installation, commissioning, training, warranty, and spare parts support with the machine manufacturer.

Conclusion

Choosing the right C/Z purlin roll forming machine requires more than comparing machine prices.

Buyers should carefully consider profile dimensions, steel thickness, material strength, automatic adjustment, punching requirements, cutting method, control system, production speed, machine structure, and after-sales support.

For manufacturers producing multiple sizes or customized orders, an automatic adjustable C/Z purlin machine can significantly improve production flexibility and reduce adjustment time.

Xiamen Xinhonghua Machinery Co., Ltd. provides roll forming solutions for different steel building applications. Our C/Z purlin roll forming machines can be customized according to customers' profile drawings, steel thickness, punching requirements, electrical standards, and production needs.

If you are planning a new purlin production line, providing your profile drawings and material specifications will help our engineering team recommend a suitable machine configuration for your project.

Local Electrical Requirements

Industrial electrical standards vary between countries.

For example, Australian customers may require equipment configured for 415V, 3-phase, 50Hz power.

Local Building and Safety Standards

Different countries have different structural and machine safety requirements.

Customers should clearly communicate the applicable local standards during the equipment selection stage.

For Australian projects, requirements may include standards related to machine safety and cold-formed steel structural design.

Customized LGS Production Solutions

At Xiamen Xinhonghua Machinery Co., Ltd., we provide roll forming equipment for different steel building applications.

For light gauge steel framing projects, our engineering team can evaluate the customer's production requirements based on:

• Building application

• Required profiles

• Steel thickness

• Steel grade

• Punching requirements

• Notching requirements

• Member marking

• CNC production workflow

• Electrical requirements

• Target production capacity

By understanding the complete manufacturing process, we can recommend a more suitable equipment configuration rather than simply supplying a standard machine.

Conclusion

Light gauge steel framing machines are helping manufacturers move from traditional manual fabrication toward automated and digitally controlled building production.

By integrating roll forming, punching, notching, cutting, marking, and CNC control, a modern LGS production system can manufacture accurate framing components for residential, modular, and prefabricated construction.

For companies planning to enter or expand light gauge steel building production, selecting the correct machine should begin with the building system itself.

Profile dimensions, material thickness, steel grade, software workflow, and local construction requirements should all be confirmed before finalizing the equipment configuration.

Xiamen Xinhonghua Machinery Co., Ltd. can provide customized light gauge steel roll forming solutions according to different building and production requirements.
