Aluminum Ladders(1)
At present, the ladders are mainly made of wood, steel, glass fiber reinforced plastic, stainless steel and aluminum alloy. First of all, we exclude the wooden ladder. It is a very dangerous ladder. Most of the wooden ladders sold on the market are made of fir, with random texture and density. The bearing capacity of each rung is far different. This often happens when a Chinese fir ladder looks very new, but one rung breaks. Steel, stainless steel and aluminum alloy belong to metal materials. Steel ladders have strong bearing capacity, but are heavy and easy to rust. Stainless steel ladders have good corrosion resistance, and are generally used for household ladders, but have poor plasticity. Anti slip treatment requires punching or adding anti slip pads; The aluminum alloy ladder has the advantages of strong bearing capacity, corrosion resistance, easy processing and light weight. Insulated glass fiber reinforced plastic ladders can be used for electrification operations.
