Galva Coat Industries Cold Formed “Purlins” for Structural Integrity 

Cold Formed “Purlins” play a critical role in modern construction. They offer essential support and strength for various building types. These components are typically used in two main systems: overlapped connections and sleeved connections. Each system serves different construction needs depending on the building design.

Overlapped Connection System

The overlapped system is ideal for large buildings with long spans. In this method, Cold Formed “Purlins” overlap at connection points, especially over rafter areas. This setup increases stiffness and load-bearing capacity. Because of this added strength, engineers often choose this system for industrial and commercial buildings where structural integrity is essential.

Sleeved Connection System

In buildings with two or more bays, the sleeved connection system provides a reliable solution. This method uses Z-shaped purlins paired with continuous sleeves. These sleeves create a smooth transition between sections, allowing for uninterrupted support. This design ensures long-term reliability even under heavy loads or challenging weather conditions.

Extension Options for Flexibility

Cold Formed “Purlins” are highly adaptable. We offer different extension methods to match your specific design needs:

• End Extension:
  This approach extends purlins or side rails to create overhangs. We manufacture these with standard end holes and add overhang fixing holes based on your project’s specifications.

• Continuous Extension:
  When the overhang requirement exceeds half the standard sleeve length, we use a continuous extension. This method supports larger overhangs while maintaining structural integrity.

• Customized Sleeve Cutting:
  For more precision, we can cut the sleeve to the exact length needed. This tailored solution gives you full control over how the purlins integrate with the rest of your structure.

Why Choose Cold Formed Purlins?

Choosing this structural solution means investing in strength, flexibility, and precision. These purlins adapt to your architectural goals while delivering performance you can rely on. No matter the environment or building type, our purlins are built to meet your needs—efficiently and effectively.
