Standard requirements for raw materials of photovoltaic tracking supports
29 Sep , 2021
Photovoltaic tracking bracket can be used repeatedly, which is very safe and economical. It is a new type of equipment, which is mainly installed in buildings or curtain walls and the ground. Therefore, manufacturers should pay attention to the selection of its raw materials to ensure the quality of equipment and ensure people’s safety. Photovoltaic tracking bracket is a special bracket for placement, installation and fixation in photovoltaic power generation system. It is mainly made of concrete, steel, aluminum alloy and other materials, and has become an important auxiliary material of green energy. The following good future photovoltaic tracking bracket company to introduce the requirements and standards of photovoltaic tracking bracket raw materials:
1. The installation materials shall have quality certificates, marks, inspection reports, indicating the variety, specifications and performance indicators of the products, and identifying contents shall meet the requirements of product standards, contract terms and design documents.
2, in accordance with the requirements of the standards for the production and installation of support materials, in accordance with the provisions of the current standard and order contract, the performance indicators of the re-inspection.
3. The surface requirements of photovoltaic tracking bracket materials should not have cracks, scarring, folding, pockmarks, bubbles, inclusion or fracture at the white layer, slag and other defects.
4, commonly used materials are divided into main material and auxiliary material:
Auxiliary materials: including connecting materials, coating materials, welding materials, connecting fasteners, anti-corrosion coatings and other.
Main material: including steel plate, steel pipe, profile and cast steel.
5. If we need to use imported materials, we also need to have corresponding certificates of qualification according to corresponding standards.
6. Pipe and profile materials should meet the requirements of corresponding standard documents in China.
7. Photovoltaic tracking bracket can only be made and installed after it is qualified.
