Product description

The tennis referee chair is made of round and square tubes, and the main material is steel, which reflects the strong sturdiness and durability of the referee chair. Suitable for all kinds of tennis competitions, including schools, communities, clubs, and professional leagues. Before spraying, the surface of each pipe fitting is shot blasted. This step is to remove the oxide layer, rust and other impurities on the surface of the steel pipe by mechanical methods, improve the cleanliness and roughness of the surface, and thus enhance the adhesion between the spray layer and the steel pipe. It can effectively prevent the pipe from rusting due to oxidation, and can maintain the stability of the structure.
