The market is full of metal composite panel products, how to avoid the purchase trap? Insiders know, seize the three core indicators will be able to make the right choice.
First look at the composite process. High-quality products using hot-rolled composite or explosive composite technology, the interface bonding strength of up to 150MPa or more, with a hard object scratching will not appear delamination phenomenon; and poor-quality products are more adhesive composite, high-temperature environment is easy to delaminate, the service life of not more than 5 years.
Secondly, check the coating performance. Building exterior boards need to choose fluorocarbon coating, its pencil hardness should reach more than 3H, resistance to artificial accelerated aging test needs to be more than 2000 hours, to ensure that many years later can still maintain bright colors. Interior panels can be polyester coated or powder coated according to demand, but you need to make sure that their voc emissions are in line with national standards.
Finally, the price/performance equation. In addition to the unit price of the panels, consider installation accessories, construction time and maintenance costs. For example, the use of locking installation system of composite panels, maintenance and replacement costs than the traditional riveted 60% lower than the long-term use of more cost-effective. It is recommended to choose to provide a complete warranty system of the brand, to avoid small losses.
Mastering these key indicators, you will be able to pick out the metal composite panel products that are really suitable for your project in the complicated market.
