The accumulated sand area of fasteners shall not exceed 100 square millimeters. No scale is allowed on the surface of fasteners. The remaining technical requirements of the project comply with the provisions of GB15831-2006.
1, anti-deformation ability. Compared with ordinary steel plate stamping fasteners, due to different manufacturing processes, the traditional stamping process has exceeded the material thickness (pressing process can only reach the thickness limit of 3.5 mm, in the actual use of the process due to insufficient strength and easy deformation) And to reach 5 mm, it can completely prevent distortion during use, thus ensuring product safety and repeated effective use. Right angle fasteners can ensure the good performance and use of fasteners in use, and ensure normal use during construction.
2, anti-slip performance. The anti-sliding property of the fastener ensures that the steel pipe and the fastener are in the state of a mating surface, and the area of the fitting is large. This overcomes the disadvantages of the cast iron fastener and the steel pipe in point or line fitting, eliminates the hidden danger of the steel pipe slipping off, and ensures the use of the steel pipe. Security effect. The anti-sliding performance of the steel pipe fasteners better overcomes the disadvantages of the cast iron fasteners and the steel pipes in the point or line fitting, which can effectively reduce the errors and safety accidents during construction.
