The special materials for bridge handrails include stainless steel, copper, aluminum alloy, hot-dip galvanized special-shaped steel pipes, electroplated special-shaped steel pipes, etc.
Stainless steel is the most common bridge handrail material, with a smooth surface, not easy to rust, and good corrosion resistance, durability and aesthetics. According to different use environments and needs, the material and thickness of stainless steel are also different, and the common ones are 304 stainless steel, 316 stainless steel, etc.
Copper is also a common bridge handrail material, which has good thermal and electrical conductivity, as well as good corrosion resistance and aesthetics. Copper is generally made of copper or brass, and the surface can be polished, drawn, sprayed and other treatments to improve its corrosion resistance and aesthetics.
Aluminum alloy is also a commonly used bridge handrail material, which is light weight, high strength, good corrosion resistance, and easy to process and install. Aluminum alloy handrails are generally made of aluminum oxide alloy, and the surface can be sprayed, electrophoresis and other treatments to improve its corrosion resistance and aesthetics.
Hot-dip galvanized special-shaped steel pipe is also a commonly used bridge handrail material, and its surface is hot-dip galvanized, which has good corrosion resistance and durability. At the same time, the shape and size of the special-shaped steel pipe can be customized according to needs to meet different design needs.
Electroplating special-shaped steel pipe is a surface treatment method, which can form a protective film on the surface of the steel pipe to improve its corrosion resistance and aesthetics. The color and gloss of the electroplated special-shaped steel pipe can be adjusted according to the needs to meet different design needs.
In addition to the above common special materials for bridge handrails, there are some other materials such as carbon steel, PVC pipes, etc., which are also used in the manufacture of bridge handrails. Different materials have different characteristics and scope of application, which need to be selected according to the specific use environment and needs.
