TV Mount manufacturers usually choose two kinds of cold rolled steel to produce TV bracket: galvanized sheet (Q215) and normal plate (Q195). Q represents the bear point of carbon steel out of shape, 195/215 means yield point values. Unit MPa, (N/mm2). Two materials are manufactured according to GB/T 3524 standard.
The galvanized sheet is improved cold rolled steel(SPCC). Advantages are as follows:
1. higher hardness, bending stronger: 1.5mm Q215 equivalent to 1mm Q195 steel plate performance.
2. Spray paint will not change color: Q215 surface is silver, Q195 surface is black, Q215 can be painted with white color, and Q195 can not.
3. More corrosion resistance, not rust: Q215 galvanized sheet rust resistance close to stainless steel, and Q195 more easily oxidized, long time will be deformed.
All of LETUO TV mount products are used galvanized sheet, if you interest, please feel free to contact us.
