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 Safety & Storm Drainage Capacity
Class A1 non-combustible galvanized steel producing zero smoke or droplets.
Engineered box and secret gutters are sized to withstand extreme 100-year rainfall peaks, eliminating building roof overflow risks.
08 Assembly & Joint Detailing
Flashings and gutters are overlapped by min. 10–15 cm with double lines of polyurethane sealant or butyl mastic, mechanically fastened with rivets or self-drilling stitch screws. Thermal expansion joints must be installed every 15 meters on continuous gutter runs.
09 Applications & Market Sectors
10 Logistics: Truckload & 40ft Container Stuffing
Bundled on wooden dunnage with protective PE wrapping. A 13.60m truck carries up to 24 tons (approx. 6,000 – 8,000 linear meters).
Packed into ISPM-15 certified wooden crates. A 40ft HC holds approx. 22–24 tons of custom flashings.

Related & Complementary Products
Cold-formed C and Z purlins replace heavy hot-rolled steel sections, reducing structural weight by up to 40% while accelerating bolting speed with factory-punched holes.
Roof sandwich panels with rigid PUR foam are designed with 3 or 5 ribs to deliver structural span rigidity, storm resistance and continuous thermal insulation for industrial, commercial and storage buildings. Produced continuously with customizable lengths to eliminate end-laps. The reinforced 5-rib geometric crown profile is fully certified for solar photovoltaic (PV) rooftop mounting rails without compromising envelope watertightness.
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.
Standard PUR wall panels provide fast installation and dependable weather sealing for exterior walls and internal partitions in warehouses and production facilities.
Concealed-fix panels hide all fasteners within the joint tongue, creating clean architectural shadow lines, uniform facades and preventing water ingress at screw points.
Water tightness and architectural aesthetics of a metal building envelope depend directly on coordinated flashings, ridge caps, valley gutters and corrosion-resistant fasteners.
