Types of scaffolding coupler

Scaffolding coupler are mainly used in two components to connect and fix. So what kinds of Scaffolding coupler are there? Let's have a look!

Scaffolding coupler can be divided into right angle, rotation and butt according to the shape. Right angles are used for vertical cross pipe connections, and swivel coupler are used for arbitrary cross pipe connections. Butt coupler are used for butt joints of steel pipes. Among the three types of coupler , the most practical one is the rotary fastener, also called the slewing fastener, which can be used regardless of the connection method of the two steel pipes. The use of butt coupler is limited and can only be used for butt joints between two steel pipes.

In addition, coupler can also be divided into external coupler , internal coupler , solid plate coupler , pig ear coupler , cantilever beam coupler , half coupler , ladder coupler , mushroom head coupler , etc.; Surface treatment is divided into: hot-dip galvanized coupler , electro-galvanized coupler , painted coupler , etc.;

1.Hot-dip galvanized couplers: After degreasing, pickling, dipping, and drying, the scaffolding couplers are immersed in the molten zinc solution for a certain period of time and then taken out.

2. Electro-galvanized couplers: Electro-galvanized couplers are scaffolding couplers that need to be processed by degreasing and pickling with electrolysis equipment, then put them into a solution of zinc salt, and then connect the negative electrode of the electrolysis equipment; Place a zinc plate on the opposite side of the piece and connect it to the positive electrode of the electrolysis device, turn on the power, and use the directional movement of the current from the positive electrode to the negative electrode to gradually deposit a layer of zinc on the surface of the coupler.

3.High Protected paint couplers: Spray paint is a coating method that is sprayed through a spray gun or a disc atomizer, dispersed into uniform and fine droplets by means of pressure or centrifugal force, and applied to the surface of the coupler.

The above is the relevant content of the scaffolding coupler introduced to you and what to pay attention to when using scaffolding coupler. I hope it can help friends in need. If you need to know more about it later, please pay attention EK scaffolding.
