C Purlin

The C Purlin is economical and reasonable, with high material utilization. Compared to hot-rolled steel sections, it can save 20% - 35% of steel, offering a significant cost advantage. It is lightweight, making transportation and installation easy, and greatly improving construction efficiency. The hot-dip galvanized surface treatment gives it excellent corrosion resistance and long service life, reducing maintenance costs in the later stages. With diverse specifications and consistent opening orientation, it facilitates unified construction.

Tianjin Shunchen Industrial Company, located in the Daqiuzhuang Industrial Zone in Tianjin, specializes in various businesses including deep processing of steel materials. With 12 rigorous process flows and over 20 years of production experience, we have maintained a 12-year zero-default record. Our products undergo three passivation treatments, ensuring guaranteed quality. We can precisely meet diverse needs, providing peace of mind and reliability for procurement.

Details

C Purlin is a lightweight steel material processed into a C-shaped cross-section through cold bending. It is primarily used as a secondary load-bearing member in steel structures, known as purlins, to support roof panels and wall panels (such as color steel plates and sandwich panels), withstand wind and snow loads as well as self-weight, and transfer the loads to the main steel frame. Its open design facilitates bolt fixation and pipe insertion, making it one of the most economical and widely used profiles in lightweight steel structure buildings. It is suitable for steel structure projects such as industrial plants, warehouses, and light steel villas.

The C Purlin is economical and reasonable, with high material utilization rate. Compared to hot-rolled steel sections, it can save 20%-35% of steel. It is lightweight, easy to transport and install, and has high construction efficiency. With hot-dip galvanized surface treatment, it has excellent corrosion resistance and long service life

The specifications are complete, and the openings are oriented in the same direction, facilitating unified construction.

C Purlin vs Z-shaped steel: how to choose? C Purlin is suitable for flat roofs or wall systems with a slope of ≤15°, featuring simple installation and good symmetry; when the slope is steeper or continuous overlap is required, Z-shaped steel has more advantages.

AQ (Frequently Asked Questions)

Q1: Which one is more suitable for my project, C-shaped steel or Z-shaped steel?

A: For roofs with a small slope (≤15°) or wall systems, C Purlin is recommended for its simpler and more economical installation; for steeply sloped roofs, Z-shaped steel is preferred.

Q2: How to calculate the amount of C-shaped steel required?

A: It is designed based on span, spacing (usually 1.5-2.2m), and load. We provide a free selection calculation sheet.

Q3: Does it support special sizes or cutouts?

A: We fully support customization, including length, thickness, and pre-drilled holes. Please feel free to provide us with drawings.

Q4: Can a test report be issued?

A: We can provide a full set of documents including material certificates, galvanizing reports, certificates of origin, etc.
