Electro-galvanized couplers: Electro-galvanized couplers are scaffold couplers that need to be processed by degreasing and pickling with electrolysis equipment, then putting them into a solution of zinc salt and then connecting 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. Hight 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 using pressure or centrifugal force, and applied to the surface of the coupler.
