A variety of surface treatment processes are provided to enhance service life and appearance, such as zinc plating for basic rust prevention, hot dip galvanizing for harsh outdoor conditions, black oxide treatment and passivation. These processes effectively improve wear resistance and anti-corrosion ability of the finished products.

Apart from standard products, we warmly welcome custom orders from clients all over the world. We are able to develop bolts with non-standard head shapes, sealed bolts fitted with waterproof rings and nylon patch lock bolts for anti-loosening purposes.
