Product Q&A

Q:Difference between Hot Rolled Round Steel and other steel types?

Hot Rolled Round Steel is a long steel product with round/square cross-section, produced by hot rolling, material Q235B/Q355B/45#, size range 5.5-250mm diameter. Compared to plate and sections, bar has compact section, uniform longitudinal stress, suitable for shafts, rods, pins and machining raw material. Selection: round/square section, axial loading, machining raw material -> bar.

Q:How to calculate theoretical weight?

Round bar weight (kg/m) = diameter(mm)2 x 0.00617; Square bar = side(mm)2 x 0.00785; Hex bar = across flats(mm)2 x 0.0068. Example: phi50 round = 502 x 0.00617 = 15.425 kg/m; 50x50 square = 502 x 0.00785 = 19.625 kg/m. Actual weight varies +/-3-5% due to tolerance.

Q:Can custom cut and fabricate?

Yes. Standard 6m, 9m, special cut per requirement (max 12m). We offer per-drawing cutting, turning, milling, drilling, heat treatment (annealing/normalizing/quenching+tempering), surface treatment (blackening/galvanizing/chrome plating) as value-added services, delivering ready-to-use finished parts.

Q:How to select material?

Q235B/Q355B/45# for general structural and mechanical parts; higher strength -> Q355B/40Cr; high hardness wear resistance -> spring steel/tool steel; good machinability -> 45# normalized. Provide part working conditions (load, speed, temperature, environment) for precise material selection advice.

Q:MOQ and lead time?

Stock sizes: 1 tonne MOQ, 3-7 days. Special material and size: custom rolling, MOQ 3 tonnes, 15-30 days. Fabrication adds time per workload. Large orders can lock mill capacity for batch delivery per schedule.
