SGCC vs SECC Galvanized Steel for Home Appliances

SGCC vs SECC Galvanized Steel for Home Appliances

Company /

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

Galvanic corrosion occurs when stainless steel & galvanized steel screws come into contact.

Can stainless steel & galvanized steel be mixed?

Company /

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

Why does galvanized steel rust Galvanized steel plates are rust resistant

Why does galvanized steel rust? 4 common reason and what do

Company /

Many people believe that galvanized steel will never rust because it has a protective zinc coating. However, in certain environments, galvanized steel can indeed rust. Understanding the reasons behind this can help you choose materials and maintain the steel more effectively. Below, we’ll explain in simple terms why galvanized steel can rust and how to address it. I. The Rust Prevention Principle of Galvanized Steel Before explaining why rust forms, let’s briefly understand why galvanized steel is rust-resistant. Zinc is more reactive than iron. When the coating is intact, zinc preferentially reacts with oxygen and water to form a dense zinc oxide or basic zinc carbonate film, preventing the internal

Electrical steel – Basic material for modern energy economy

Company /

Electrical steel, also known as silicon steel sheet, is a soft magnetic alloy of silicon and iron with extremely low carbon content. The efficiency of the vast number of motors, transformers, and generators produced globally each year directly depends on the quality of electrical steel. Simply put, without electrical steel, there would be no modern power system. It is considered the “crown jewel” of the steel industry and an important benchmark for measuring a country’s level of special steel production. I. What is Electrical Steel? The core function of electrical steel is to minimize energy loss during the conversion between electrical and mechanical energy. It needs to possess extremely high

H-beam vs I-beam detailed comparison guide

H-Beam Vs I-Beam: What’s the Difference?

Company /

H-beam vs I-beam are the two most common types of structural steel, often compared together by designers, engineering contractors, and project owners. Although the two have similar appearances, there are significant differences in cross-sectional shape, mechanical properties, load-bearing capacity, and application scenarios. Section shape: The fundamental difference between H-beam vs I-beam The cross-sectional shape of H-beam is H-shaped, with wide and thick flanges, parallel inner and outer surfaces, and a middle web connecting the upper and lower flanges. The overall cross-section is close to a square. Due to the close width of the flange and the height of the section, H-beams exhibit excellent stability when subjected to bi-directional loads. The
