High polymer plastic steel bridge supports are mainly divided into composite plastic steel bridge supports and lined steel plastic steel bridge supports. They are a new type of bridge support product, widely used in industries such as chemicals, oil, electricity, and construction, as well as coastal areas. They can replace the current traditional cable bridge supports and have been widely adopted in developed countries in Europe and America. As a cable bridge support for future engineering applications, it complies with the national policy of "replacing steel with plastic." It features flame retardancy, corrosion resistance, excellent mechanical strength, good insulation performance, reasonable structure, attractive appearance, and long service life. It is developed by integrating the usage of steel, glass fiber reinforced plastic, and aluminum alloy bridge supports under various working conditions and climatic conditions.
