SGCC vs SECC Galvanized Steel for Home Appliances

Blog, NEWS / wanzhigroup

Galvanized steel sheet is one of the most common metal materials used in the manufacture of home appliances such as refrigerators, washing machines, air conditioners, and microwave ovens. It not only determines the product’s corrosion resistance, appearance quality, and lifespan, but also directly affects manufacturing costs and subsequent coating effects. Currently, the two most commonly used types of galvanized steel in the home appliance industry are SGCC hot-dip galvanized steel sheet and SECC electro-galvanized steel sheet. Although both are galvanized steel, they differ significantly in production processes, coating thickness, corrosion resistance, surface smoothness, and application locations. So, which is more suitable for home appliance manufacturing: SGCC or SECC? What is

Can stainless steel & galvanized steel be mixed?

Blog, NEWS / wanzhigroup

In engineering, stainless steel & galvanized steel (mainly austenitic stainless steel such as 304/316 & hot-dip galvanized HDG) often appear in the same structure. Stainless steel panels are fixed with galvanized brackets, galvanized bolts are screwed into stainless steel components, and stainless steel bolts are used to connect galvanized steel purlins, etc. However, a new question arises at this point: can stainless steel and galvanized carbon steel be used in direct contact? The answer is: it can be done in most conventional building environments, but there is a risk of Contact corrosion under specific conditions, and insulation isolation measures need to be taken. In fact, the contact between stainless steel
