Manufacturing Process
Material Selection
High-grade carbon steel or malleable iron sourced from certified mills. Spectrometer tested for chemical composition.
Precision Forging/Casting
High-quality forging or investment casting ensures consistent wing geometry and material density throughout.
Thread Cutting
Precision thread cutting or rolling ensures smooth adjustment and consistent engagement with mating threads.
Dimensional Inspection
100% thread gauge inspection ensures perfect fit with standard scaffold threaded components.
Tensile Testing
Regular tensile testing verifies mechanical properties exceed industry standards.
Hot-Dip Galvanizing
Immersion in molten zinc (ZD ≥ 80µm) provides exceptional corrosion protection for decades of service life.
