Material and Craftsmanship

Base material: National standard malleable cast iron (Magang), white cast iron graphitized annealed, with high toughness, impact resistance, and low brittleness, different from ordinary pig iron castings;
Surface treatment: High temperature anti rust red paint spraying, isolated from water vapor corrosion, outdoor construction site resistant to sunlight and rain; Customization of hot-dip galvanized rust resistant products according to needs;
Tightening accessories: equipped with 4.8 grade high-strength bolts and nuts, with precise threads, sufficient locking force, and not easy to slip or loosen.

Core technical parameters

Suitable pipe material: Φ 48mm building welding scaffold steel pipe (national standard general specification)
Anti sliding bearing capacity: The anti sliding load of a single fastener according to the national standard is ≥ 8.0kN, which meets the requirements of the building construction load code
Anti destructive performance: Made of malleable cast iron material, it is resistant to impact and cracking, and is not easily broken when fastened at high altitudes
Applicable temperature: -30 ℃~60 ℃, all climate construction site environment

Product advantages

Excellent toughness: Made of Magang forging, it is not easy to break when struck or tightened, and the failure rate is significantly reduced compared to gray iron fasteners;
Flexible installation: The division of labor for the three types of fasteners is clear, covering all three working conditions of vertical, diagonal, and extension, making the installation of the frame convenient and efficient;
Secure fastening: The bolt locking structure is not easy to slip off after being subjected to force, ensuring the overall stability of the scaffold and improving the construction safety factor;
Corrosion resistant and durable: with a baked paint protective surface, it is not easy to rust or age during long-term use on outdoor construction sites, and has a long service life;
Strong universality: The globally accepted standard for Φ 48 pipes is applicable to domestic infrastructure, overseas housing construction, and road and bridge projects.
