Product Description

Product Description

GALVANIZED PURLINS - Durable & Versatile Steel Framing for Any Structure

Galvanized purlins are mainly used for the support system of the roof and walls of steel structure buildings. They have good anti-corrosion properties through galvanizing and are suitable for construction sites that need to resist corrosion for a long time, especially in areas with high humidity and severe corrosion environments. Galvanized purlins are widely used in various construction projects, such as roof support systems of steel structure workshops and warehouses, as well as light bridges, canopies, and other anti-corrosion structures.
 
Our comprehensive range includes a variety of profiles to meet diverse design needs, including versatile C purlins, interlocking Z purlins, sturdy U purlins, and robust rectangular hollow section (RHS) tubes.

This selection ensures you have the perfect component for use as roof purlins, wall girts, and other framing applications. Their lightweight steel framing design ensures ease of handling and faster installation, significantly reducing project timelines and labor costs. With a high strength-to-weight ratio, galvanized purlins deliver powerful performance without the bulk, making them the most cost-effective solution for industrial, commercial, and agricultural buildings.

CONSTRUCTION FIELD 

MUNICIPAL ENGINEERING

MECHANICAL MANUFACTURING

Galvanized purlins are widely used in the construction field, mainly used in roof support systems of steel structure workshops, warehouses, and other places. They can provide solid support to ensure the safety and stability of the building. 

In municipal engineering, galvanized purlins are often used in light bridges, canopies, and other structures that require corrosion protection. Their anti-corrosion and wear-resistant properties make them perform well in these environments and extend their service life.

Galvanized purlins are also used in some equipment brackets or frame structures, especially in the field of mechanical manufacturing. They can provide stable support to ensure the normal operation and safety of equipment.

* Superior Corrosion Protection: 

Hot-dip galvanized coating provides exceptional resistance to rust and environmental degradation, significantly extending lifespan in harsh conditions.

* High Torsional Rigidity: 
Square tube profile offers excellent resistance to twisting and bending, ensuring greater structural stability and load-bearing capacity compared to open sections.

* Enhanced Aesthetic Appeal: 
Enclosed square section provides a cleaner, more finished look, suitable for applications where visual appearance is important.

* Optimized for Heavy Loads: 
Its robust, closed-section design makes it ideal for supporting heavier roofing and wall cladding materials, providing reliable performance.

* Reduced Maintenance Requirements: 
The durable galvanized finish and enclosed profile minimize the need for ongoing maintenance, leading to lower long-term operational costs.
