06 RAL Color Options & Aesthetics
In addition to standard stock colors, custom batch coil coating is available across the international RAL classic spectrum.
07 Fire Rating & Structural Rigidity
Class A1 non-combustible steel producing zero toxic smoke or flaming droplets.
Minimizes dead load on secondary steel framing, improving earthquake safety and overall building structural economy.
08 Assembly & Joint Detailing
Panels are fixed directly into steel purlins using color-matched self-drilling fasteners with integrated vulcanized EPDM sealing washers. Factory-applied joint seals eliminate air leakage.
09 Applications & Market Sectors
10 Logistics: Truckload & 40ft Container Stuffing
Single-skin trapezoidal and composite deck profiles stack compactly, meaning standard road transport is governed by the 24,000 kg legal payload limit. A 13.60m trailer carries approx. 3,500 to 5,000 m² of profiled sheets.
In 40ft High Cube ocean containers, up to the maximum legal payload of 26,000 kg (approx. 4,000 to 5,500 m²) of profiled sheets is loaded with certified ISPM-15 dunnage and steel strapping.

Manufactured from 1200 mm steel coils to provide a full 1000 mm effective cover width with 6 ribs. Fewer end-laps, faster installation, and maximum area coverage per panel make it the industrial benchmark for factory roofs and warehouse walls.
Produced from 1000 mm coils to deliver 800 mm cover width with 5 ribs. An exceptionally cost-efficient single-skin steel sheet solution for agricultural canopies, site fencing, light roofing, and industrial wall cladding.
Galvanized omega (top hat) profiles offer an exceptionally lightweight, rigid substructure solution for horizontal and vertical architectural cladding, interior ceiling framing, and solar panel mounting rails. The symmetrical hat section allows secure surface anchoring while providing air ventilation space behind cladding panels.
Galvanized C profiles are engineered for simple span roof purlins, vertical wall girts, door/window framing, and solar PV ground mounting structures. CNC automated hole punching according to fabrication drawings ensures rapid, bolt-together site assembly with zero on-site cutting or welding.
CNC-bent box gutters and custom flashings ensure complete rainwater collection, storm drainage and clean structural transitions for large roofs and facades.
Water tightness and architectural aesthetics of a metal building envelope depend directly on coordinated flashings, ridge caps, valley gutters and corrosion-resistant fasteners.
