The aggregate sand area of fasteners shall not exceed 100 square mm. No oxide skin is allowed on the surface of the fastener. The remaining technical requirements meet the requirements of GB15831-2006. 1, strong deformation resistance. Compared with ordinary steel plate stamping fasteners, due to the different production process, the traditional stamping process has broken through the limit of material thickness (the stamping process can only reach the thickness limit of 3.5 mm, and it is easy to deform in the actual use of the process because of insufficient strength) to reach 5 mm, which can fully ensure the use of the process without deformation, thus ensuring the safety and repeated and effective use of the product. The right Angle fastener can ensure the good performance and use of the fastener in use, and ensure the normal use of the construction.
2, strong skid resistance. The slip resistance of the fastener ensures that the steel pipe and the fastener are in the state of fitting surface, the fitting area is large, and the shortcomings of the cast iron fastener and the steel pipe are in point or line fitting are overcome, the hidden danger of the steel pipe slip is eliminated, and the safety effect is ensured when the steel pipe is used. The skid resistance of steel pipe fastener overcomes the shortcomings of point or line fitting between cast iron fastener and steel pipe, and can effectively reduce the errors and safety accidents in construction. 3, the fastener has safety advantages, quality advantages, brand advantages, this fastener has a good product advantage, can make the construction to show a good advantage. The rental of steel scaffold saves worry and effort, and the rental income exceeds the rental of inferior iron fasteners, so the good characteristics of this scaffold fastener are more widely used in construction.
4, easy maintenance. Because the fasteners themselves are not easy to rust and damage, the maintenance after use is very convenient, which not only reduces the difficulty of maintenance but also saves the maintenance cost, reduces the manpower and material resources of maintenance, and increases the efficiency and quality of construction. 5, strong corrosion resistance. After passivation and galvanized double anti-rust treatment, the anti-rust ability is greatly improved, and the service life is long, far exceeding the service life of cast iron fasteners. 6. Strong anti-stripping ability. The new type of connection and the new type of nut ensure that the fastener can always be fixed vertically and firmly in the case of deformation of the steel pipe, eliminating the possibility of slipping of the steel pipe
