What is Galvanized & Coated Steel?
Galvanized and coated steel refers to steel products protected with metallic or factory-applied coating systems to improve corrosion resistance, durability, surface performance, and service life. Depending on the product, these coatings may include zinc, aluminium-zinc, zinc-aluminium-magnesium, or pre-painted colour finishes.
The most common coated steel products include:
- Galvanized Steel (GP)
- Galvalume Steel
- PPGI Colour Coated Steel
- ZAM Zinc-Aluminium-Magnesium Coated Steel
These products are widely used where steel is exposed to outdoor environments, humidity, chemicals, or coastal conditions.
