What are the performance indicators of color coated plate?

The material requirements of the building (roof panel and exterior wall panel) itself can be divided into safety performance (impact resistance, wind pressure resistance and fire resistance), residential performance (water resistance, heat insulation and sound insulation), durability (pollution resistance, weather resistance and appearance retention), production processing (economy, easy processing, easy maintenance and repair).

Safety and service life are of utmost importance to the ultimate owner of the building. For the design unit, the service life, bearing capacity, appearance and so on are more important. For the molding processors of building walls and roofing, the processability of color coated plates (surface hardness, wear resistance, plate shape and steel plate strength) is the preferred requirement.

Of course, the quality of the color coated plate mainly depends on the color coated plate production plant, but if the processing and installation equipment and methods are improper, it will also cause damage to the appearance and service life of the final product to varying degrees.

Substrate: yield strength, tensile strength, elongation

Coating: coating weight, binding force

Coating: color difference, gloss, T bending, impact, hardness, resistance to pulverization, resistance to moisture and heat, etc

Surface: surface defects visible to the naked eye

Plate shape: tolerances, irregularity, etc
