Product Description
Motorcycle pillars are structural supports that connect the frame and body, mainly serving to support the body and passenger loads. The importance of the pillar is self-evident. If the pillar loses its supporting function, the motorcycle will not be able to travel normally and may even cause serious safety accidents.
The materials of motorcycle pillars mainly include carbon steel and alloy steel,.
1.Carbon steel: Carbon steel is a type of steel containing carbon elements, which has good strength and plasticity, relatively low cost, and is currently one of the most widely used materials for motorcycle pillars.
2.Alloy steel: In addition to carbon, alloy steel also contains other alloying elements, which have high strength and hardness. It is suitable for use in high load, high-strength motorcycles, but the cost is relatively high.
Our company specializes in producing steel pipes for motorcycle pillars, with various specifications available. The surface is black or saponified. We provide supporting services for major motorcycle brands both domestically and internationally.like Honda, Suzuki, Yamaha, Daye, Haojue , etc
