Pressed Steel Coupler

Pressed Steel Coupler (stamped steel fastener) is a type of steel connector manufactured through a cold stamping process. It is mainly used to connect components such as steel pipes and profiles, and is widely applied in scenarios like construction scaffolding, light steel structures, and temporary facility erection.

Key Feature Analysis:

Manufacturing Process: Using low-carbon steel plates (e.g., Q235) as raw materials, the main structure of the fastener is formed in one or multiple passes through cold processing and shaping (including blanking, bending, punching, and other procedures) on a press with stamping dies. It is then completed through surface treatment (galvanizing, painting, etc.) and accessory assembly. The advantages of this process lie in high production efficiency, low cost, and suitability for mass production.

Performance Characteristics: Lightweight (superior to cast iron or forged steel fasteners) and easy to install. The low-carbon steel material endows it with certain toughness, making it not prone to brittle fracture. However, its load-bearing capacity is limited by the thickness of the steel plate (usually suitable for medium to light load scenarios).

Common Types:

Right-Angle Pressed Coupler: Used for 90° connections between vertical and horizontal steel pipes, such as fixing scaffolding vertical poles and crossbars.

Swivel Pressed Coupler: Can flexibly adjust the connection angle, adapting to diagonal bracing or irregular structures.

Straight Pressed Coupler: Used for the straight-line extension connection of two steel pipes.
