- Versatile Corrugation: Various wave heights (18–35 mm) and pitches ensure compatibility with different roofing and cladding systems, enhancing water drainage and structural stability.
- Customizable Dimensions: Widths from 600 mm to 1250 mm and lengths up to 12 meters (or custom cuts) allow flexible installation and reduced waste.
- 10-Year Warranty: Confidence in material quality and workmanship is backed by a full decade of coverage, reducing long-term maintenance risks.
- Mill Test Report (MTR): Each shipment can be accompanied by a certified MTR showing chemical composition, mechanical properties, and coating weight – essential for specifiers and inspectors.
