IT4 Box Profile 2.5m Roofing Sheet, Charcoal Grey

IT4 Box Profile Roofing

The IT4 Box Profile Sheet provides a high-tensile solution for industrial and residential roofing applications. This pre-painted galvanized steel panel features a deep-trough design for maximum water discharge. It suits low-pitch roofs and high-rainfall areas where drainage efficiency remains a priority.

Built for the Job

Contractors specify this profile for its structural rigidity and ease of installation over standard purlin spacings. The 2.5-metre length works effectively for smaller structures, lean-tos, or specific bay sizes in larger warehouses. The charcoal grey finish offers a modern aesthetic while providing a durable barrier against UV degradation and oxidation. Site teams use these panels for both wall cladding and roof covering due to the trapezoidal rib strength.

• Industrial warehouse roofing and side-wall cladding for weatherproofing.

• Residential perimeter fencing or gate cladding for security and privacy.

• Carport and shed construction requiring high-capacity water drainage.

Product Highlights

Corrosion Resistance

The base metal undergoes a hot-dip galvanizing process before receiving a multi-layered color coating.

Structural Integrity

• Four-rib trapezoidal design increases longitudinal stiffness.
• Minimal deflection under standard wind and snow loads.
• Deep troughs prevent water ingress during heavy tropical downpours.

Technical Specifications

What’s Included

• 1 x 2.5m IT4 Box Profile Iron Sheet (Charcoal Grey)

On-Site & Workshop Notes

• Fasten the material using 65mm or 75mm self-drilling roofing screws with EPDM washers to ensure a watertight seal.

• Maintain a minimum end lap of 150mm when installing on slopes above 15 degrees to prevent backflow.

• Wear protective gloves during handling to avoid injury from factory-cut sharp edges on the panels.

• Store the units off the ground on timber dunnage to prevent moisture accumulation between stacked sheets.
