1. Prepainted Zincalum Steel Coil PPGL brief introduction
It is manufactured by galvanizing a steel coil with coating of Aluminum (55% in weight ratio
but 80% in surface volume ratio) Zinc (43.4% in weight ratio) and Silicon (1.6% in weight ratio)
2. Prepainted Zincalum Steel Coil PPGL common application
Roofing, Walling, Cladding, Siding, Automotive (Non-exposed Items) Construction Ducting
Cooler Solar Heating Panel Structural Scaffolding Brooder Reflector
3. Prepainted Zincalum Steel Coil PPGL quality control
Strict procurement process---skillful technical workers---final products inspection (resistance
to corrosion, salt spray test, exposure test, machinability, thermal resistance)---standard packing
4. Prepainted Zincalum Steel Coil PPGL package materials
1) Each bare coil to be securely tied with two bands through the eye of coil and one circumferential
2) The contact points of these bands on the coil edge to be protect with edge protectors
3) Coil then to be wrapped with water proof /resistant paper, properly and completely metal wrapped
4) Wooden and iron pallet can be used or as your requirements
5.Prepainted Zincalum Steel Coil PPGL coating types and function
1) Polyester(PE)
2) Silicon modified polyester(SMP)
3) High durability polyester(HDP)
4) Polyvinylidene fluoride(PVDF)
