Why are the market prices of roof racks very different? Many people don’t understand the reasons, especially if the design looks similar or even the same product. Why is the price so different?      

Why is the market price so different? It is mainly caused by the disparity in the materials used in the products.       

First, there are two materials, aluminum alloy, and high-strength plastic, at the main support. Among them, the aluminum alloy material has the advantages of high strength and lightweight, so it is used most widely, but the trace elements contained in the aluminum alloy are different, and the strength and hardness of the manufactured material are also different;       

High-strength plastic materials are more prone to aging because plastics are prone to thermal expansion and contraction, and assembly precision is relatively poor. Now some well-known brands generally use the aluminum alloy, manganese steel, and other materials, which not only enhances strength, hardness and anti-aging. Level.       

After the roof rack is installed, the rationality of its mechanical structure is judged from whether it is easy to deform or not. It depends on the thickness of the material used to see if the joint is tightly connected. After the roof rack is installed, it is judged whether it is easy to deform or not. The rationality of the mechanical structure.      

 How to identify the material of the roof rack?       

The material is the core of quality. We can identify it by simple observation to see if the surface gloss is consistent, whether it is uniform, whether there are bumps and cracks; depending on the thickness of the material, see if the joint is tightly connected.
