Technical Parameters:

PPGL Advantages:

1. Corrosion Resistance

The aluminum-zinc alloy coating provides excellent protection against corrosion even in highly corrosive environments near coastlines or industrial areas.

2. Durability

When combined with a durable paint finish, PPGL steel sheets can last over 25 years with only nominal maintenance under normal weather conditions.

3. Strength and Support

PPGL steel is strong yet lightweight. It can support heavy loads and withstand high wind loads making it suitable for roofing and cladding applications in commercial buildings.

PPGL Applications:

1. Roofing
PPGL steel is widely used for roofing purposes in industrial, commercial and residential construction due to its corrosion resistant properties and durability.

2. Cladding
The material is also commonly applied as exterior wall cladding/facades thanks to the long lasting color coated finishes that retain aesthetics over decades.

3. Rainwater Goods
PPGL profiles are commonly used to manufacture rain gutters, downpipes, flashings and other rainwater accessories around buildings.

4. Industrial Siding
PPGL panels are a practical choice for warehouses, factories, agricultural sheds due to their non-combustible properties and ability to withstand impacts.

5. Agricultural Buildings
Farm buildings like sheds, barns and stables can be economically constructed using PPGL sheets that withstand all weather conditions.
