G30 Corrugated Roofing Sheet
The Premium G30 Roofing Sheet provides a durable and weather-resistant solution for residential, agricultural, and commercial structures. This 2.5-meter pre-painted galvanized iron (PPGI) material features a standard corrugated profile to ensure efficient water runoff and structural rigidity. It is engineered to withstand tropical climates while maintaining its structural integrity over long-term exposure.
Built for the Job
Contractors and site supervisors select this specific gauge and length for versatile applications ranging from primary residential roofing to site hoarding and temporary shelters. The G30 gauge offers a balanced strength-to-weight ratio, making it manageable for manual handling on-site while providing sufficient resistance against wind uplift and impact. The Tile Red finish is applied through a high-temperature bonding process that resists peeling and chalking under intense UV exposure. For large-scale projects, the 2.5m length minimizes waste when covering standard purlin spacings and allows for flexible overlapping in both vertical and horizontal planes.

On-Site & Workshop Notes
-
Always use specialized roofing nails with EPDM rubber washers to ensure a watertight seal at the crest of the wave.
-
Overlap the sheets by at least 150mm at the ends and one and a half corrugations at the sides to prevent capillary water ingress.
-
When cutting this material, use cold-cutting tin snips or shears; avoid abrasive discs as the heat can damage the protective coating and lead to edge corrosion.
-
Store sheets off the ground on timber dunnage and keep them covered if installation is delayed to prevent moisture trap between stacked surfaces.
