Steel rebar
- Rebar gives reinforced concrete its tensile strength.
- Made mainly by electric arc furnace (EAF) steelmaking: scrap and other manufacturing waste are melted with an electric arc. Newer secondary smelting also adds metallized pellets to the furnace charge to improve melting and yield.
- Meets standard strength requirements, with good ductility and high resistance to wear and tension, so it suits civil and construction projects.
Steel sheets
- Used in automotive, construction and manufacturing.
- Hot-rolled sheets are formed at high temperature. Cold-rolled sheets get extra processing for exact dimensions and surface finish.
- Quality control covers dimensional accuracy, surface finish and mechanical properties.
Pipes and tubes
- Steel and stainless steel pipes and tubes, in straight lengths and coils.
- Square and rectangular box tubes are listed with their weights below.
Steel profiles
- Structural sections for building frames, bridges and machinery.
- I-beams, H-beams, channels, angles and T-sections, each with its own load-bearing capacity.
- Quality assurance includes checks of dimensions, straightness and surface defects, to international standards.
