Industry Use Cases

Applications

Fastener & Wire Product Manufacturing

Low/medium carbon wire rod (SAE 1006–1045, 10B21, 10B33) is the standard feedstock for cold-heading and thread-rolling lines producing bolts, nuts, screws, and rivets at scale — used across automotive, construction, and heavy machinery OEM supply chains.

Concrete Reinforcement (Rebar)

Deformed rebars (HRB400/500E, ASTM A615 Gr.60, BS B500B/C) are the backbone of every reinforced concrete structure — from foundations and slabs to high-rise columns, highway bridges, and dam walls — meeting seismic ductility requirements across global standards.

Heavy Machinery & Structural Components

SCM440, 42CrMo4, S45C, and 4140 alloy bars are machined into shafts, gears, connecting rods, and tooling for heavy machinery, mining equipment, and agricultural machinery — requiring high tensile strength, fatigue resistance, and through-hardening capability.
