IT4 Box Profile Sheet
The IT4 Box Profile Sheet provides a high-strength roofing and cladding solution for industrial, commercial, and residential structures. This 3-meter charcoal grey panel features a distinct four-trough profile designed for superior water runoff and structural rigidity. It suits various roof pitches and wall cladding applications where long-term durability is the primary requirement.
Built for the Job
Contractors specify this profile for projects requiring high load-bearing capacity and a modern aesthetic. The angular box design allows for efficient installation on large-span warehouses and residential units. It performs exceptionally well on low-pitch roofs where traditional corrugated sheets might risk water ingress. The charcoal grey finish provides a professional appearance while offering high resistance to UV degradation and thermal expansion.

On-Site & Workshop Notes
-
Ensure purlin spacing does not exceed 1.2 meters for optimal support under heavy rain loads.
-
Always use self-drilling screws with EPDM washers to maintain a watertight seal on the crests.
-
Overlap by at least one full trough to prevent capillary action and water leaks in high-wind areas.
-
Store these metal panels off the ground on timber dunnage to prevent moisture buildup between sheets.
-
Use cold-cutting tools like nibblers rather than angle grinders to preserve the factory coating edges.
