punch the steel before its cold rolling process .(Only 0.02mm error per hole , 2mm error per column).
3）cold rolling :
All columns and beams are auto shaped by the rolling machine ,and auto cut in size with the max error 1mm per column.
4） Welding: Using Japan OTC welding machine .the automated welding not only ensures the quality but also make the surface clean and smooth.
5）Surface Processing: A complete automatic production line (High pressure Static electricity ) Raw powder material is the Akesu powder, The quality and processing steps are .
A Beams, Columns, Steel Shelve → Surface Clean → rust off → Phosphating → Powder Coated → Backing → Finished product;
B The surface of the finished products is sprayed by high pressure static electricity Thickness of the powder is 60 to 80 micron on average;
C The powder is closely attached and gets the “0 “level of the international GB/T9286-1998 standard;
D Hardness (wear resistance) As 100 times hard as the normal Nitrocellulose lacquer, and get “2H” level of the China GB6739-86 standard;
E Corrosion resistance In a Hydrochloric acid trial (GB/T1771-91) more than 500 hours Make sure it’s qualified.
