IT4 Box Profile Iron Sheet
The IT4 Box Profile Sheet provides a high-strength roofing solution designed for rapid installation and long-term weather protection. This 2.5-metre panel uses a trapezoidal 4-rib configuration to maximize water runoff capacity and structural rigidity across various purlin spacings. It serves as a primary cladding material for both residential dwellings and industrial warehouses.
Built for the Job
Roofing contractors select this specific profile because it offers a wider effective cover compared to traditional corrugated sheets. The 2.5m length is specifically useful for small-scale outbuildings, porch extensions, or as part of a tiered roofing system where shorter runs reduce material waste. Site supervisors prefer this material for its predictable overlap performance and ease of handling during high-altitude installations. The steel base undergoes a rigorous galvanizing or Aluzinc coating process before the Tile Red finish is applied, ensuring the core remains protected from oxidation even in humid environments.

On-Site & Workshop Notes
-
Use self-drilling roofing screws with EPDM washers to maintain a watertight seal at fixing points.
-
Avoid using angle grinders to cut the steel as the heat destroys the protective zinc coating; use tin snips instead.
-
Store the panels on a slight incline if kept outdoors to prevent water trapping between stacked layers.
-
Ensure the side lap faces away from the direction of the prevailing wind to prevent moisture ingress.
