External Hex Hexagon Expansion Screw Sleeve Concrete Anchor Bolt

Surface galvanized expansion bolts are fasteners with corrosion resistance and high temperature resistance,

and their surfaces have been galvanized.

The following is a detailed introduction to surface galvanized expansion bolts:

Material and surface treatment:

Expansion bolts are usually made of metal materials such as carbon steel.

Surface galvanizing treatment not only enhances the anti rust ability of bolts, but also makes them more durable.

The galvanized layer can protect bolts from environmental factors such as moisture and corrosion, extending their service life by 12.

Model and specifications:

There are various types of galvanized expansion bolts, including M6, M8, M10, M12, and other specifications.

There are also multiple length options, such as 50mm, 60mm, 70mm, etc., to meet the needs of different usage scenarios.

Galvanized expansion bolts are widely used in various fields such as construction, machinery, curtain walls, elevators, steel structures,

fire protection, doors and windows. Its corrosion resistance and high temperature resistance make it an ideal choice for

humid environments or situations that require long-term exposure to the outside world
