We also provide a one-stop solution service from material selection and technical consultation to delivery.

Steel Bar
A type of hot-rolled ribbed steel bar with surface ribs (crescent ribs/equal height ribs). It is mainly processed by hot rolling and cold rolling. Rebar has a yield strength (MPa) ≥400, possessing high seismic resistance. It is mainly used for beam and column reinforcement in steel structure frames, foundation pile cap reinforcement, and floor slab load-bearing reinforcement.
Specifications
- Material: HRB400E, HRB500E, etc.
- Diameter: Φ12-Φ40mm.
- Length: 9m/12m (can be cut to size as needed).

Wire Rod
Hot-rolled, disc-shaped low-carbon steel wire rod is hot-rolled steel supplied in coils. It is produced through hot rolling and has a yield strength (MPa) ≥Q195-Q235. It possesses good drawing properties and can be used directly as a steel structure material or as a raw material for further processing.
Specifications
- Material: Q195, Q235
- Diameter: Φ5.5-Φ16mm

Coiled Rebar
Coiled rebar, primarily with small diameters, is hot-rolled and coiled. It has a yield strength (MPa) ≥400 and combines the mechanical properties of rebar with the convenience of wire rod, making it easier to transport.
Specifications
- Material: HRB400E, HRB500E;
- Diameter: Φ6-Φ12mm

Steel Wire
Fine wire made from wire rod through drawing, annealing, and other processes. Yield strength (MPa) ≥500-1600+, possessing extremely high strength and toughness. Finely sized, suitable for applications such as binding, cables, and protection.
Specifications
- Material: Low carbon steel, high carbon steel;
- Diameter: Φ0.8-Φ6mm

Steel Bar
Solid long steel bars with various cross-sectional shapes, including round, square, and flat bars, produced by hot rolling/cold drawing. Yield strength (MPa) ≥235/355, highly versatile.
Specifications
- Material: Q235B (standard structure), 45# steel (high strength, requires heat treatment);
- Cross-section dimensions: Round Φ10-Φ200mm, Square 10×10-200×200mm;
- Length: 6m/9m standard length.

Profiles Steel
Including angle steel, I-beams, H-beams, channel steel, and other long steel bars with specific cross-sectional shapes and dimensions, hot-rolled/welded, yield strength (MPa) ≥235/355, forming the main load-bearing framework of the steel structure.
Specifications
- Angle Steel: Material Q235B/Q355B; Width 20-200mm, Thickness 3-24mm
- I-Beam: Material Q235B/Q355B; Model 10#-63# (e.g., 20# I-beam, height 200mm)
- H-Beam: Material Q235B/Q355B; Model 100×100-900×300mm (e.g., 300×150×6.5×9)
- Channel Steel: Material Q235B/Q355B; Model 5#-40# (e.g., 16# channel steel, height 160mm)

Steel Pipe
Includes hollow section steel materials such as seamless steel pipes and welded steel pipes. Common manufacturing processes include welding after steel strip coiling and two methods: hot rolling, cold drawing, or cold rolling solid tube blank piercing. These tubes are lightweight, have high bending and torsional strength, and a yield strength (MPa) ≥235 / 245, making them widely applicable.
Specifications:
- Types: Seamless steel pipe (structural use), straight seam welded pipe (low-pressure fluid use), spiral welded pipe (large diameter);
- Material: Q235B, Q355B (structural use), 20# steel (seamless pipe, high-pressure applications);
- Specifications: Outer diameter Φ10-Φ630mm, wall thickness 2-20mm (e.g., Φ108×4mm, commonly used in support columns).
