| Classification | Standard No. | Type | Designation | Application and features |
| Hot Galvalume | Q/BQB422-2000 | Non-alloy hot galvalume | SPCC SPCD SPCE | For general use, mechanical seam, deep punching and super deep punching. When galvaluming weight is large, it has superior anti-corrosion. It can be taken as exposed parts, small galvanization weight and processing performance. |
Q195 Q235 Q345 | As structure steel, sound anti-corrosion and processing performance. Low alloy steel, steel weight can be reduced for steel structure, superior anti-corrosion and processing performance. | |||
| Alloy hot galvalume steel belt | SPCC SPCD SPCE | For punching, structure use and cold-forming, compared to pure galvanization, adhesion and weight of alloy hot galvanizing is much better. But dusting may occur during processing, it performs better for base material of color coating plate in anti-corrosion and adhesion |
