Types of coupler on scaffolding

Fasteners are connections between steel pipes and steel pipes. There are three basic forms: right-angle coupler, sleeve scaffolding coupler, and swivel scaffolding coupler.

(1) Right-angle coupler: used to connect two steel pipes that cross each other perpendicularly,

(2) Rotating fastener: used to connect two steel pipes intersecting at any angle.

(3) Butt joint fastener: used for the butt connection of two steel pipes, the form of the fastener is (a) right-angle fastener; (b) rotating fastener; (c) butt fastener.

In terms of technology, it can be divided into: casting coupler, stamping coupler, forging coupler, etc. Among them, casting is not as good as stamping in quality, and stamping is not as good as forging;

From the surface treatment, it is divided into: hot-dip galvanized coupler, electro-galvanized coupler, spray-painted coupler, etc.;

From the purpose of use, it can be divided into: right-angle coupler, sleeve scaffolding coupler, external coupler, internal coupler, fixed plate coupler, pig ear coupler, suspension beam coupler, half coupler, fixed ladder coupler, mushroom head coupler and many more;

In terms of weight, it can be divided into: light coupler and heavy coupler;

From the implementation standard, it can be divided into: national standard coupler, British coupler, German coupler, American coupler, Australian coupler, Italian coupler, Japanese coupler, Korean coupler, etc.; different execution standards Applied in different countries and regions;

From the specification, it can be divided into: 48*48, 48*60, 60*60 and others; the specification refers to the outer diameter of the steel pipe.
