SURFACE TREATMENT
Three ways of surface treatment can be adopted: galvanizing, painting and untreated, of which hot- dip galvanizing is recommended. |
|
Hot-dip galvanizing |
It is a form of galvanization. It is a process of coating steel grating with a thin zinc layer. By passing the metal through a molten bath of zinc, the average coating thickness is 70μm when steel bards range from 3mm to 5mm in thickness. |
Painting |
It is also a good way to get surface protective film. Coating thickness depends on the customer's choice. |
