Generally, electrolytic plates are divided into phosphating treatment plates and passivation treatment plates. Phosphating treatment is more common, and the steel number is SECC-P, also known as P material. Passivation treatment plates can be divided into oiled and non-oiled plates.
Cold-rolled steel plate (SPCC) looks very dark, and SPCC-SB is too bright, so it is called golden plate. There is also hot-dip galvanized thick steel plate (SGCC) which has an advantage over electro-galvanized plate (SECC). SECC sheet metal bending and cross-section It is easy to rust, but SGCC is much easier! High-quality surfaces generally use SECC or SGCC galvanized sheets. The surface of thick steel sheets made of this material has a shiny color and has the gloss of metal. The advantage of this kind of thick steel sheet is that it is corrosion-resistant. Good ability.
Electro-galvanized steel sheet (SECC): uniform dark gray, mainly imported, resistant to fingerprints, has excellent corrosion resistance, and maintains the process performance of cold-rolled steel sheets. Main uses: electrical products, computer casings and some door frames and panels, GNEE STEEL can produce them.
Hot-dip galvanized thick steel plate (SGCC): dip-plated, bright milky white, small zinc flowers, I think it is impossible to see the zinc flowers, the large zinc flowers are very obvious, you can see the hexagonal flower blocks.
Key features: corrosion resistance; paintability; formability; butt weldability. to
Main use: extremely common, small electrical appliances, good appearance, but more expensive than SECC, many manufacturers have changed to SECC in order to reduce costs.
