Color Steel

Silicon Polyester
Prepainted steel sheet is coated and baked with paint containing silicon resin.
It is a popular construction material because of its highly weather resistant properties.
Countries, including Korea, that have industrial complexes along their coastal regions will find it more economical to use steel plates coated with Si-P/E paint than PE paint.
USAGE

 The Silicon Polyester steel used this building

  • -Sandwich panel
  • -Steel plate for roof in factory complex

Applied materials

Hot-dip galvanized steel sheet(KS D 3506, GI)

The cold rolled steel sheet passes through a molten zinc pot containing 97% zinc (0.03% or less AL), undergoing the galvanizing process, 
which gives each side of the sheet an equal thickness of coating.
Depending on the surface treatment of the plated sheet, it is categorized into regular spangle, 
minimized spangle, or zero spangle ultra smooth, which are symbolized as R, M, Z, respectively. 
Prepainted steel sheet produced by Dongbu Steel uses ultra smooth material in the production process.

 
Aluminum steel sheet(KS D 6701)

While aluminum is light in specific gravity, it possesses high tensile strength. Due to its superb anti-corrosion properties, aluminum is widely u sed in the production of aircrafts, automobiles, containers, blinds, ceiling material, and composite panels.

Cold rolled stainless steel sheet(KS D 3698)

Due to its anti-corrosion and chemical resistant properties that far exceed other steel products, stainless steel sheet is optimum for products that require extremely high levels of corrosion resistance and durability. Stainless steel sheet takes is produced from Iron/Chrome or Nickel/C hrome alloy. STS 304 or STS 430 are used mainly for PCM (JIS uses the symbol SUS).
