Marine Ladders can be divided into steel ladders, aluminum ladders, which are commonly used in two kinds. Steel ladder because of its own heavy, and easy to rust corrosion, after hot galvanizing treatment of rust anti-corrosion performance greatly improved, but the surface finish is difficult to improve, that is, affect the surface aesthetics, the current ship owners rarely choose.
Marine ladder materials using aluminum magnesium alloy, light weight, strength and steel is better, after anode oxidation treatment has a good rust and corrosion resistance, while the surface finish is high and beautiful, so now international and domestic ship owners are more inclined to use aluminum ladder. Aluminum ladder is made using international standards, reliable design requirements concept, widely used in the marine industry.
There are many types of ladders used in ships, steel ladders and aluminum ladders are commonly used in two, that is, the use of different materials and the name, aluminum ladders are the use of high-quality aluminum alloy materials, the use of lightweight and secure, it and the use of steel ladders have a great difference.
