The thickness of the hot dip galvanized steel coil we supply: 0.14mm-2.0mm.

For the color of the prepainted steel coils, generally, the back paint is RAL 9002 color, the top paint will be based on the clients' request, like RAL 9002, RAL 9016, RAL 5020, RAL 6017, RAL 9010, all of the RAL colors, or confirmed by the samples.

Package for the the steel coils:Water-proof paper inside, then the protective film and cover the steel sheet with the steel strip, protective plate in the both section.

For the prepainted steel coil/color coated steel coilTop coat: 17-25um(any color, as per the RAL code or client's sample)Back coat: 5-7um(it is RAL 9002 color generally)

1.Resistance to corrosionAl-Zn coated steel sheet has better performance in corrosion resistance than GI sheet of the same thickness and its service life is 1-5times longer than general GI sheet.2.Thermal resistanceCommon HDG steel plate normally works under 230℃, and has its color changed at 250℃, however, Galvalume steel sheet can sustain the environment at 315℃ for long time.3.High reflectivity...

For the packages of the corrugated steel sheetWater-proof paper inside and then cover the steel sheet with steel strip, steel pallets under.

The based materials of prepainted steel coils below:1. hot dip galvanized steel coils2. hot dip aluminum zinc alloy coated steel coils(hot dip galvalume steel coils)3. electro galvanizing steel coils

generally, there are two kinds of galvanized steel coils.1. hot dip galvanized steel coils2. cold galvanizing or electrogalvanizing steel coils

We mainly supply hot dip galvanized corrugated steel sheet, galvalume(aluzinc coated) corrugated steel sheet and prepainted corrugated steel sheet.

The chemical composition of the galvalume steel coils we supply:55%-Aluminum, 43.4%-Zinc, 1.6%-Silicon

BMT means the thickness of the raw material.TCT means the thickness of finished products.For example:Galvanized steel sheet: 0.16mm(TCT), means the thickness after galvanized
