Nanjing Uni-tech Metalwork Company Ltd is a professional Nanjing-based enterprise which has been in operations with over ten years of manufacturer and trading of scaffolding and formworks accessories.

The company's commitment to supplying high-quality scaffold, backed by excellent customer service, has won it a worldwide reputation for efficiency and reliability. All the products in their range meet high safety standards and are checked and tested before dispatch.

Construction couplers according to the process is divided into three kinds, cast iron couplers, pressed couplers, forged couplers. Cast iron coupler raw material malleable steel process casting, surface adhesive paint treatment, pressed coupler raw material Q235 plate, process pressed, surface plating color zinc treatment. Forged coupler raw material q235 raw steel, process forging, surface plating white zinc treatment. Each coupler is mainly divided into three types, cross, rotation, and connection. The following describes the differences between the three types and the specific use on the steel pipe. The cross coupler is used to connect and fix two steel pipes through a 90-degree cross. Cross coupler is also the most used coupler. Take a look at the installation example. Rotary couplers can be 360 degrees at random Angle cross and vertical cross, the two steel pipes are fixed, can be flexible, but there is no cross couplers construction fast, so generally only used for not 90 degrees outside the cross and vertical cross place use, please see the installation example below. Connecting couplers can connect two steel pipes on a horizontal line to form a whole, so that the whole is more solid and reliable, please see the installation example below. Finally, our company can provide a variety of construction couplers, welcome to consult.

High quality forged scaffolding couplers are produced in this way, couplers detailed forging process for:

1. According to the different couplers to design the corresponding drawings and processing technology.

2. Prepare the mould used in the forging process, do a good job before the use of the mould preparatory work.

3. Control the metal materials needed for the couplers in the forging process.

4. Heat treatment and cold working according to the needs of the products.

5. After the forging is completed, Shot blasting or sand blasting, so as to obtain high-precision finished products.
