Related & Complementary Products
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.
Galvanized Z purlins feature asymmetric flanges (narrow/broad) allowing them to nest together over support frames. This creates a continuous structural beam that dramatically reduces mid-span deflection and permits smaller sections or wider frame spacing, saving up to 15% overall steel weight on large industrial roofs.
Standard PUR wall panels provide fast installation and dependable weather sealing for exterior walls and internal partitions in warehouses and production facilities.
The 18/76 corrugated sinusoidal profile delivers timeless architectural rhythm through its continuous, flowing wave pattern. Equally suited for horizontal and vertical facade cladding, barrel-vault curved roofs, and modern industrial headquarters, it combines high weather tightness with elegant shadow lines.
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.
CNC-bent box gutters and custom flashings ensure complete rainwater collection, storm drainage and clean structural transitions for large roofs and facades.
