 Precoated Galvanized Steel Sheet 

Bangkok Steel Industry Public Co., Ltd., is widely known as a leading manufacturer of high standard reinforcing steel bars and Galvanized Sheet and coil. In 1992, we imported the machinery line with the latest technology in manufacturing Precoated Galvanized Steel from Japan, thus becoming the first manufacturer of its kind in Thailand conforming to the Japanese Industrial Standard (JIS G3312) which is recognized worldwide.

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, BSI's Precoated Galvanized Steel products are therefore, colorful and have excellent corrosion and weather resistance.



 Fine Surface Finish 

BSI's Precoated Galvanized Steel Sheets have uniform quality and uniformly colored coating film since they are manufactured from the latest color coating line. 

 Excellent durability 

Because of our tight zinc coating steel sheet and special color resin coating in two coated - two baked, BSI's Precoated Galvanized Steel Sheets have the excellent corrosion and weather resistance and keep their lifetime for a long period of service.

 Good formability 

BSI's Precoated Galvanized Steel Sheets 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.


Since they require no additional coating and have excellent durability, compared to steel sheets coated at site, thus saving coating expenses.
