Standard IT4 Box Profile Roofing Sheet, 3m, Tile Red

IT4 Box Profile Roofing Sheet

The Standard IT4 Box Profile roofing sheet provides a high-performance covering solution for structural envelopes in industrial, commercial, and residential sectors. This 3-meter section features a trapezoidal profile engineered to maximize structural rigidity while maintaining a manageable weight for site handling. The tile red finish consists of a multi-layered protective coating that resists UV degradation and prevents premature corrosion in exposed environments.

Built for the Job

Roofing contractors and site supervisors specify this profile for its superior water-shedding capabilities compared to traditional corrugated iron. The four-rib design creates deep channels that efficiently direct high volumes of runoff during heavy tropical downpours. This characteristic makes the material suitable for low-pitch roofs where drainage speed is critical to prevent moisture ingress at the laps. The 3-meter length serves as a versatile standard for medium-scale outbuildings, residential extensions, and perimeter fencing projects. The high-tensile steel core ensures the sheet maintains its shape under moderate foot traffic during installation or maintenance cycles.

• Industrial warehouse roofing where high-capacity drainage is a primary requirement.

• Residential roofing and cladding for modern aesthetic and structural durability.

• Permanent site fencing and hoarding for secure construction perimeters.

Product Highlights

Corrosion Resistance

The base metal features a galvanized or Alu-Zinc coating that prevents oxidation in humid conditions.

Structural Rigidity

• Deep trough design increases load-bearing capacity across purlins.
• Minimal deflection over long spans compared to circular profiles.

Technical Specifications

What’s Included

• 1 x 3-Metre IT4 Box Profile Iron Sheet (Tile Red)

On-Site & Workshop Notes

• Ensure purlin spacing does not exceed 900mm to maintain structural integrity under environmental loads.

• Use 65mm or 75mm self-drilling roofing screws with EPDM washers to create a watertight seal on the ribs.

• Overlap by at least one full rib for standard slopes, or two ribs for pitches below 10 degrees.

• Store sheets in a dry, slanted position if not installing immediately to prevent capillary moisture buildup between stacked surfaces.

• Always use cold-cutting tools like nibblers or metal shears; avoid abrasive discs that can burn the protective coating.
