High-Strength Galvalume Profile Sheets
Anti-Corrosive AZ150 Alloy • Weatherproof Seal
Engineered Weather Protection & Architectural Aesthetics
Roof and Wall Cladding forms the critical protective envelope of any industrial steel building. It shields the internal operations, machinery, and inventory from heavy monsoons, intense ultraviolet solar radiation, and extreme temperature fluctuations, while defining the contemporary visual identity of the facility.
Gapat Engineering fabricates and supplies premium pre-painted Galvalume (PPGL) and Bare Galvalume profile sheets engineered with high crests and anti-siphon capillary grooves. Combined with matching flashings, gutters, downspouts, and self-drilling neoprene fasteners, our cladding systems guarantee complete waterproofing and aesthetic excellence.
Roof Cladding Profiles
- Deep trapezoidal crests (28–32mm) for rapid drainage
- Engineered anti-siphon capillary groove prevents water ingress
- High load-bearing capacity under heavy wind & rainfall
- Suitable for low-slope industrial roofs down to 1:10
Wall Cladding & Facades
- Crisp architectural profile ribs for modern aesthetic facades
- Horizontal or vertical installation orientations
- Integrated corner trims, louvers & framed openings
- Impact-resistant high-tensile steel core (550 MPa)
Galvalume Metallurgy
