Features of steel products

ASTM A653 is the American standard for the galvanized steel.The Grade 340 means the Yield strength of the galvanized sheet will be 340Mpa or more.   

For the galvanized corrugated steel sheet in 0.20mm*800mm.800mm is the width after corrugation, generally, the most of clients need the length in 1800mm, 2440mm, 3000mm or 3600mm etc0.20mm*800mm*1800mm          about 390 pieces per metric ton0.20mm*800mm*2440mm          about 290 pieces per metric ton0.20mm*800mm*3600mm          about 196 pieces per metric ton

For the galvanized corrugated steel sheet in 0.20mm*900mm.900mm is the width after corrugation, generally, the most of clients need the length in 1800mm, 2440mm, 3000mm or 3600mm etc0.20mm*900mm*1800mm          about 353 pieces per metric ton0.20mm*900mm*2440mm          about 261 pieces per metric ton0.20mm*900mm*3600mm          about 176 pieces per metric ton

Generally, there are two kinds of cold steel sheet, annealed and unannealed.In using, there are several kinds, like commercial quality, drawing, deep drawing and construction use. 

For the cold steel coils we supply, the grade is Q195, SPCC or SAE 1008  

For the coil ID of the galvalume coils, it will be 508mm or 610mm. 

For the coil ID of the galvanized steel coils, it is 508mm or 610mm.

For the coil OD of the prepainted steel coils, it is relavant with the coil weight of the prepainted steel coils,Generally, the coil OD is 1000mm-1100mm.

For the coil OD of the aluzinc steel coils, it is relavant with the coil weight of the aluzinc steel coils,Generally, the coil OD is 1000mm-1100mm.

For the coil OD of the galvanized steel coils, it is relavant with the coil weight of the galvanized steel coils.Generally, the coil OD is 1000mm-1100mm. 

For the coil ID of prepainted steel coils we supply is 508mm or 610mm.Generally, the clients from Russia, Ukrain etc need the 610mm.Most of areas like Africa, Southeast Asia, South America need the 508mm.  

For the corrugated sheet, we mainly supply galvanized corrugated sheet, galvalume(aluzinc coated) corrugated sheet, prepainted corrugated steel sheet.Generally, the thickness is 0.13mm-0.60mm.

 For the color of the top side of the prepainted steel coils(color coated steel coils), it will be as per the RAL CODE or sample from clients.Like RAL 9016, RAL 3005, RAL 3011, RAL 6005, RAL 3018, RAL 5017, RAL 5012, etc. 

For the prepainted steel coils(color coated steel coils),  the top color will be as per the clients' request based on the RAL code or sample.The back color is RAL 9002(white grey) generally.
