Cast Iron Industrial Scaffold Fastener Corrosion Resistant For Building Support Systems

Scaffolding fasteners are the core safety components that connect steel pipe support systems in building construction, made of high-strength malleable cast iron (KT-450 grade) or special alloy steel, and are treated with multiple anti-corrosion processes to ensure excellent performance in various extreme environments.

Core product range
Right-angle fasteners: Specially designed for vertical cross-connection of steel pipes, with a two-bolt symmetrical fastening structure, anti-slip bearing capacity ≥ 12.5kN, meeting the highest level requirements of GB24911 national standards.
Rotary fastener: 360° all-round connection system, equipped with self-calibrating spherical washers, breaking torque ≥ 35N·m, to meet the needs of various complex angle erections.
Butt fasteners: realize the axial precision docking of steel pipes, use taper locking technology, and the tensile strength ≥ 4.8kN to ensure continuous and reliable force transmission of vertical rods.
Bowl buckle joint: modular socket system, octa-tooth locking structure, single node ultimate load ≥ 85kN.

Technical feature advantages
Triple safety design: mechanical locking, elastic self-locking, visual warning system, built-in pressure-sensing gasket to monitor the preload status in real time

Super durability: The thickness of the hot-dip galvanized layer is ≥ 95μm, and with epoxy sealing coating, the service life is more than 12 years

Intelligent installation system: Patented quick-release structure realizes one-handed operation, single fastener installation time ≤ 8 seconds, and the erection efficiency is increased by 50%

Full-cycle traceability: Laser engraving unique identity code supports digital quality management from production to scrap

Material and process breakthroughs
High-strength materials: using new alloy formulas, the tensile strength is ≥ 450MPa, and the weight is reduced by 20% compared with traditional products

Precision Casting: The lost foam casting process ensures dimensional tolerances within ±0.2mm

Surface treatment: Eight pre-treatment processes Double anti-corrosion coating, salt spray resistance test for more than 3000 hours

Low temperature toughness: Charpy impact power ≥ 27J in -40°C environment, suitable for construction in alpine areas
