Will the engineering telescopic ladder rust for a long time?
In fact, it will not be rusty after a long time for engineering telescopic ladders, because the surface of the aluminum alloy ladder will be done and oxidized. Otherwise, who dares to buy it? It ’s not to mention the engineering ladder, not.
The aluminum alloy ladder is made from high -strength aluminum alloy materials. It is characterized by the weight of light weight and high strength, and it is more convenient for the operating intensity of the construction personnel.
Aluminum alloy ladders have the most widely used non -ferrous metal structure materials in the industry, which have been applied in large quantities in aviation, aerospace, automobiles, machinery manufacturing, ships and chemical industries. The rapid development of the industrial economy has increasing demand for aluminum alloy welding structures, and the research on welding of aluminum alloy has also deepened.
