Scaffolding Coupler for Construction Engineering
A scaffolding Coupler is an essential part of a tube and coupler scaffold. They are used to fix two vertical steel pipes, parallel or at any angle, so as to provide a temporary working platform for high-altitude operations. Scaffolding couplers usually need to comply with EN74 / BS1139 standards.

Scaffold couplers used to connect steel pipes when building scaffolds, and connectors between steel pipes and other structures, are widely used in various types of scaffolding projects. There are usually European standards and Japanese standards. HZPT, as China's leading scaffolding coupler supplier, focuses on introducing European standard scaffold fasteners to meet the use of the following countries, Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, and the United Kingdom.

Types of Scaffolding Coupler
The following five ways to classify help you find the scaffold couplers you want.
(1) British Standard
According To British Standard, EN74-1:2005, Scaffold Coupler Can Be Divided Into The Following Four Types based on Usage Scenarios:
(2) Different Countries
According To The Requirements And Usage Scenarios Of Different Countries, Scaffold Coupler Can Be Divided Into The Following Types:
(3) Production Processes
According To Different Production Processes, There Are Mainly The Following Three Types:
(4) Surface Treatments
The Different Surface Treatments, Is Divided Into The Following Three Categories:
1. Hot-dip galvanized couplers: After degreasing, pickling, dipping, and drying, the scaffold couplers are immersed in the molten zinc solution for a certain period and then taken out.
2. 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.
