Product Overview

C purlins feature a symmetrical channel-shaped profile and are commonly used for simple spans, wall girts, door frames, and equipment supports. Z purlins have an offset profile that allows sections to overlap at supporting points, making them suitable for continuous-span roofing systems.

We manufacture galvanized and painted C/Z purlins in customized dimensions, thicknesses, lengths, hole patterns, and surface finishes. Production can be completed according to structural drawings, material lists, or project specifications.

Main Product Advantages

High Strength-to-Weight Ratio

Cold-forming technology produces lightweight sections with excellent structural strength, helping reduce the total weight of the steel building.

Customized Production

Web height, flange width, lip size, thickness, length, hole position, and surface treatment can be customized according to project drawings.

Accurate Dimensions

Automated roll-forming, punching, and cutting equipment helps maintain consistent dimensions and accurate connection holes.

Easy Installation

Pre-punched holes and lightweight sections simplify on-site handling, bolted connection, and installation.

Corrosion Protection

Galvanized steel provides reliable corrosion resistance for industrial, commercial, agricultural, and prefabricated buildings.

Efficient Transportation

C/Z purlins can be nested and bundled, reducing packaging volume and improving container-loading efficiency.

FAQ

1. Can you customize the dimensions of C/Z purlins?

Yes. Web height, flange width, lip size, thickness, length, and hole position can be customized according to your structural drawings.

2. Which type should I choose, C purlin or Z purlin?

C purlins are commonly selected for simple spans, wall girts, and secondary supports. Z purlins are often used for continuous roof spans because they can overlap at supporting points. The final selection should be confirmed through structural design.

3. Can you provide pre-punched holes?

Yes. We can produce round, oval, and customized holes according to approved drawings, reducing on-site drilling and installation time.

4. What surface treatments are available?

Available options include galvanized, painted, and uncoated finishes. The appropriate surface treatment depends on the building environment and corrosion-protection requirements.

5. Can you manufacture purlins according to our drawings?

Yes. Please provide CAD drawings, PDF drawings, a material list, or detailed dimensions. Our technical team will review the information before production.

6. Can C/Z purlins be supplied with other steel building components?

Yes. We can supply primary steel frames, bracing systems, roof and wall panels, connection components, fasteners, and other steel building accessories.
