Trade Grade IT4 Box Profile Iron Sheet, 3m, 28 Gauge, Charcoal Grey

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.

• Industrial warehouse roofing and side-wall cladding.

• Residential roofing for modern architectural designs.

• Site hoarding and temporary perimeter fencing for construction zones.

Product Highlights

Structural Rigidity

The four-trough trapezoidal design increases the moment of inertia, allowing for wider purlin spacing without sagging.

Corrosion Protection

• Multi-layered coating including Aluzinc or galvanized substrate.
• Weather-resistant charcoal grey topcoat prevents chalking and peeling.

What’s Included

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.
