Colored zinc-plated gaskets are passivated on the basis of electrogalvanizing to form a rainbow-colored passivation film (containing trivalent chromium or hexavalent chromium) with a film thickness of about 0.5-1μm. Its anti-corrosion performance is significantly better than ordinary electrogalvanizing, and the surface color is bright, with both functionality and decorativeness.

Electroplated galvanized gaskets are gaskets that deposit a zinc layer on the surface of carbon steel or alloy steel through an electrolytic process. The thickness of the zinc layer is usually 5-15μm. Its surface is silvery white or bluish white, and it has both anti-corrosion and decorative functions. It is one of the most commonly used surface treatment methods in the industrial field.

The umbrella handle anchor is named because the end of the bolt is a J-shaped hook (similar to the umbrella handle). It consists of a threaded rod and a J-shaped hook. The hook part is completely embedded in the concrete to provide pull-out resistance.

The welded plate anchor consists of a threaded rod, a welded pad and a stiffening rib. The pad is fixed with bolts by welding to form an integrated structure of “bolt + pad”. The pad increases the contact area with the concrete, disperses the load and improves stability.

The 7-shaped anchor is named because one end of the bolt is bent in a “7” shape. It is one of the most basic types of anchor bolts. Its structure includes a threaded rod body and an L-shaped hook. The hook part is buried in the concrete foundation and connected to the equipment or steel structure through a nut to achieve a stable fixation.
