Detailed Photos & Description

Product Description
This is a metal expansion sleeve,made of galvanized steel. It has a cylindrical shape with a longitudinal slot. The smooth, metallic surface suggests good durability and resistance to corrosion.

 

Manufacturing Process

1. Material Selection: High - quality steel is chosen, which is then galvanized to prevent rust and enhance longevity.
2. Forming: The steel is formed into a cylindrical shape through processes like stamping or extrusion.
3. Slotting: A longitudinal slot is cut into the cylinder, which allows for expansion.
4. Finishing: The surface is smoothed and treated to ensure proper functionality and appearance.

Function

The expansion sleeve is used to create a secure anchoring point in a pre - drilled hole. When a fastener (such as a bolt) is inserted and tightened, the sleeve expands against the walls of the hole, providing a firm grip and distributing the load. This helps to prevent the fastener from pulling out and ensures a stable connection.

Application Scenarios

• Construction and Building: Used in anchoring fixtures to concrete or masonry walls, such as installing handrails, shelves, or heavy equipment mounts.
• Mechanical Engineering: For securing components in machinery to solid bases, ensuring that vibrations or forces do not loosen the fasteners.
• Infrastructure Projects: In the installation of signs, streetlights, and other outdoor fixtures that need to be firmly anchored to the ground or other structures.
