IT4 Box Profile 2.0m Roofing Sheet, G28, Charcoal Grey

IT4 Box Profile Roofing

The IT4 Box Profile Sheet provides a high-strength roofing and cladding solution for residential, commercial, and industrial structures. This 2.0-meter section features a deep-ribbed Inverted Trapezoidal (IT4) profile designed to maximize structural rigidity and water discharge capacity. The charcoal grey finish offers a professional aesthetic while providing superior resistance against harsh environmental conditions.

Built for the Job

This profile is engineered for high-performance applications where structural integrity is a priority. The four-rib configuration increases the load-bearing capacity of the panel, allowing for wider purlin spacing compared to traditional corrugated sheets. Contractors typically utilize these 2.0-meter lengths for smaller roofing spans, wall cladding, or as part of a tiered roofing system on larger sites. The charcoal grey coating is specifically formulated to withstand high UV exposure without significant chalking or fading.

• Residential roofing and perimeter fencing where high security and durability are required.

• Industrial warehouse cladding and roofing for superior weather protection.

• Carports, sheds, and temporary site offices requiring fast installation.

On-Site & Workshop Notes

• Use 50mm self-drilling screws with EPDM washers to ensure a watertight seal on the ribs.

• Maintain a minimum side overlap of one and a half corrugations for low-pitch roof installations.

• Store this material in a dry, covered area if not for immediate use to prevent moisture entrapment between stacked sheets.

• Always use a cold-cutting tool such as nibblers or shears; avoid high-speed abrasive discs which can damage the protective coating.
