Basic functions: High - efficiency waterproofing, safeguarding the core of the building
Seamless splicing waterproof system
The metal substrate itself has excellent impermeability. Paired with a specially designed overlapping structure (such as buckle - joint and lock - edge processes), it can form a complete waterproof barrier, preventing rainwater from penetrating into the roof structure layer.
Suitable for steep - pitched sloping roofs, and it can still maintain tightness even under extreme weather conditions such as heavy rain and snowmelt.
Long - term weather resistance
The surface colored stone particles or coatings are treated with anti - corrosion and UV - resistance. They can resist natural damages such as UV aging, acid rain erosion, and salt spray corrosion, extend the service life of the roof (usually up to more than 50 years), and reduce the risk of water leakage.link:http://www.guiyuansteel.com
