Galvanized steel plate is divided into ordinary electrolytic plate and fingerprint resistant electrolytic plate. The fingerprint-resistant board adds a fingerprint-resistant treatment on the basis of the ordinary electrolytic board, which can resist sweat, and is generally used on parts that do not undergo any treatment. The brand is SECC-N. Ordinary electrolytic plates are divided into phosphating plates and passivating plates. Phosphating is more commonly used. The brand is SECC-P, commonly known as p material. Passivated plates are classified as oiled or unoiled.
Hot dip galvanized steel sheet (SGCC) has an advantage over electrogalvanized steel sheet (SECC). SECC bending and cross section are very easy to rust. SGCC has much better rust resistance under the same conditions. High-quality chassis usually adopts SECC or SGCC galvanized steel plate. The color of the steel plate of the chassis using this material is bright and has a metallic luster. The advantage of this steel plate is good corrosion resistance.
Electro-galvanized steel sheet (SECC): uniform gray, mainly imported, fingerprint resistant, has excellent corrosion resistance, and maintains the workability of cold-rolled sheet. Uses: home appliances, computer case shells, and some door panels and panels.
Hot dip galvanized steel plate (SGCC): dip-plated, bright white, small zinc flower (more difficult to see), large zinc flower can clearly see hexagonal flower blocks. Only China Steel and Shengyu Steel Corporation of Taiwan Province can produce in China. There are no steel factories in mainland China that can produce high-quality materials, which mainly rely on imports.
