1. Precoated galvanized steel coil brief introduction
It is produced through a process of metal coating which involves passing cold rolled coils
through a zinc pot. The process ensures the adherence of zinc to the surface of steel sheet.
The zinc layer provides excellent corrosion resistance so that it can prolong the service life
of the product



2. Precoated galvanized steel coil main features
1) Good durability, and can be used longer than galvanized steel
2) Good heat resistance, and compared with galvanized steel, under high temperature
3) Discolor easily
4) Good heat reflecting, good weldability, good adhesion
5) Machining capability and spraying performance similar to galvanized steel
6) Protective film can be provided according to customers' requirement



3.Precoated galvanized steel coil production process
The process entails the coating of Galvanized Steel Sheet with Zinc Phosphate and followed
by the roll coating with special color resin in two coated - two baked process.Under our strictly
quality control and superb quality of our raw material



4. Precoated galvanized steel coil coating structure
1) Coating systems or configurations can be ustomized as client's requirements
2) Top coat can be 3-coat system (primer + base coat + finishing coat)
3) Backing can be single service coat or primer + backer coat +finishing coat
4) Both sides can also be color coated Color matching services provided for free



5. Precoated galvanized steel coil details
It can be subject to roll forming, lock forming and press forming because they are two coated
- two baked with a high grade color resin of their tight and flexible pre - treatment film
