The fasteners commonly used in China are made of cast iron, and their mechanical properties shall meet the requirements of Steel Pipe Scaffold Fasteners (GB15831-2006), not less than KT330-08. (Sales and leasing of scaffold materials) There are three types of fasteners: right-angle fasteners, butt fasteners and rotary fasteners. Packed in woven bags, 25 pieces each. Each weight shall be 1.1KG (including bolts and nuts).
Among the cross fasteners, there is a kind of fastener called rotary fastener. Now fasteners are widely used, because sometimes we use fasteners. Forged fastener suppliers are also limited by the shape of fasteners. Although there are many kinds of fasteners sold in the market, forged fasteners, such as cross fasteners, special-shaped fasteners, semi-circular fasteners, and components of different shapes, will also be used in different environments, Now many people will use rotating fasteners, because compared with other fasteners, forging rotating fasteners has certain flexibility.
Fasteners have safety and quality advantages. Engaging in fastener leasing saves both worry and effort. The rental income exceeds the rental of inferior fasteners. Because the product itself is not easy to corrode and damage, it is easy to maintain. The maintenance after use is very convenient, which not only reduces the maintenance difficulty, but also saves the maintenance cost. The overall corrosion resistance is strong. After passivation, galvanizing and double antirust treatment, the corrosion resistance is greatly improved and the service life is long, which is far longer than the service life of cast iron fasteners. Strong anti-detachment ability, new connection is adopted. The new nut ensures that when the steel pipe is deformed, the fastener can be fixed vertically and firmly, eliminating the possibility of steel pipe sliding.
