Great thermal insulation: Cuts heat transfer to stabilize indoor temperature and save energy, suitable for extreme climate areas.
Efficient & economical installation: Pre-made panels shorten construction time by around 50% vs traditional roofs, perfect for large industrial projects.
Robust structure: Outstanding load capacity, wind resistance and long service life thanks to composite design.
Optional fireproof performance: Rock wool or PIR fire-resistant cores available to meet global fire codes for industrial & commercial buildings.
Lightweight and durable: Lighter than concrete roofing to lessen building load without sacrificing durability.
Waterproof & anti-corrosion: Coated steel prevents rust and water damage under tough surroundings.
Customizable B2B service: Provide OEM & ODM, including size (50–200mm thickness), RAL colour, length & profile adjustment, plus custom branding and packaging.
