What are the types of substrates for composite sandwich panels

1. Hot dip aluminum zinc steel plate: Its process is very similar to that of hot-dip galvanized steel plate, but the difference lies in the different zinc content and composition, as well as significant differences in appearance. There are no differences in other aspects, and its weather resistance and service life are better than galvanized steel plate.

2. Hot dip galvanized steel plate: This substrate has outstanding impact resistance, elongation rate, and yield value. This type of color steel plate has received good reviews in industries such as construction and decoration.

Color steel composite board is a national B1 level fireproof material, which has the advantages of only carbonization without combustion, no production of toxic substances, and complete recycling of waste. It is an ideal substitute for core materials such as polystyrene, polyurethane, and rock wool.

3. Cold rolled plate: Cold rolled plate is a steel plate that has not been annealed, and it is also the predecessor of galvanized steel plate and aluminum zinc coated steel plate. This steel plate has low impact resistance, high material hardness, low yield value and elongation rate, and outstanding welding performance.

4. Aluminum plate: The best advantage of aluminum plate is for use in special industries, as its price is high and the cost is a significant expense. Therefore, only special industries such as refrigeration, insulation, antivirus, sterilization, etc. can be selected. Impact function: Excellent, capable of tangible and intangible impact and bending.
