How to Properly Choose Composite Roofing Shingles

Composite resin tiles are experiencing a hot sales trend in the market due to their environmental protection, energy saving, lightweight durability, and aesthetic non-fading properties. This is particularly true for the roof replacement projects in flat-to-pitched conversions and the roof renovation projects for dangerous buildings in major cities. With the rising popularity, there have also emerged some counterfeit products. These involve substituting genuine materials with substandard ones, fraudulently obtaining certified copies of legitimate companies, and then selling these products on construction sites or through the storefronts of individual businesses. The products have shown serious quality issues, such as fading and cracking. The main cause is the use of substandard materials and improper process configurations. Specifically:

1. The surface material of Va is ASA industrial resin, where the raw materials form a recycling process during the thermal melting and extrusion process. Temperature control and technical mastery are crucial.

2. The base of Va is composed of PVC chemical raw materials, along with some auxiliary materials, which also requires thermal melting co-extrusion and a certain proportioning process of the materials. Improper operation of these two processes is a key factor in producing non-compliant products. Particularly in the cold regions of North China, enterprises must perform technical operations for the special (frost resistance) properties of the products, in order to meet the national quality (frost resistance) standard of 30 cycles. The (frost resistance) process is a technology that some small processing plants are unable to achieve. The (frost resistance) 30-cycle national quality testing requirements: According to the JC149-203 standard, the test results must show no cracks, hollowing, bubbles, or separation on the surface to be considered合格.

The launch of composite resin tiles has been accompanied by rigorous certification, modification, and testing of product performance standards by our chemical testing center, resulting in stringent quality control standards. A qualified composite resin tile must possess five inspection certificates.
