The predecessor of the high-quality PPGI corrugated roofing sheet is: hot-dip galvanized steel sheet, hot-dip galvanized steel sheet, or aluminum sheet and cold-rolled sheet. The type of the above-mentioned steel plate is the substrate of the color steel sheet, that is, the steel sheet substrate without paint and lacquer, the above steel sheet Have their own advantages and performance.

1. Hot-dip galvanized steel sheet: The substrate has good impact properties, good elongation, and yield value. The color steel plates produced in this category are well evaluated in the applications of construction, decoration and other industries.

2. Cold-rolled sheet: The cold-rolled sheet produced by cold rolled steel coil factory in stock is a steel sheet that is not annealed, and is also the predecessor of galvanized steel sheets and galvanized steel sheets. The impact properties of the steel sheet are very low, the material hardness is high, the yield value and the elongation are low, and the welding performance is good.

3. Hot-dip aluminum-zinc sheet: The process of this substrate is basically the same as that of hot-dip galvanized steel. The difference is that the zinc content of the surface is different, and the surface zinc-white phenomenon is also very different. There are basically no gaps in other aspects. Weather resistance and life expectancy are better than galvanized steel sheets.

4. Aluminum sheet: aluminum sheet accounted for the best advantage is for special industries, because its own price is high, so the cost alone is not a small expenditure, so only special industry choices: refrigeration, insulation, anti-virus, sterilization and other industries. Impact performance: excellent, can be shaped, invisible impact, bending.
