Definition & Overview of Round Bar / Flat Bar CIF Tianjin
Round bar is a solid circular section used for shafts, fasteners and general machining; flat bar is a rectangular cross‑section used for brackets, frames and base plates. Orders define section size (diameter or width×thickness), length (typically 6 or 12 m), straightness/twist tolerances and surface condition (as‑rolled or peeled/ground).
Complete packages usually include sections and plates/tubulars: U‑Channel, Angle, spans I‑Beam & H‑Beam, and base plates from Hot Rolled Sheet.
Specifications & Grades (Commercial/Structural)
Supply scope includes commercial quality and structural grades. Mechanical properties and tolerances follow mill practice; tighter tolerances/peeled surface on request.
| Product | Size Range | Thickness/WT | Length (m) | Surface | Notes |
| Round Bar | Ø 10–200 mm | — | 6 / 12 | As‑rolled / Peeled | Ground/bright on request |
| Flat Bar | Width 20–300 mm | 5–40 mm | 6 / 12 | As‑rolled | Cut‑to‑length available |
Pair with reinforcing and tubulars as needed: Rebar, Wire Rod, Hollow Section / Pipe
Applications / Market Use Cases
General fabrication, shafts and pins, base plates, brackets, frames, racks, flanges, and machining stock. In export programs, bars are combined with plates/sections to achieve better freight per ton under CIF contracts.

Logistics, Packaging & Delivery (CIF Tianjin → Tianjin/Shanghai)
Bars are bundled with steel strapping and tagged for traceability; small diameters may be sub‑bundled. Export lengths 6 m and 12 m; cut‑to‑length on request. Stowage plans protect edges and surfaces; early booking aligns rolling with vessel cut‑offs to Tianjin and Shanghai.
Combine shipments with complementary sections/tubulars for landed‑cost efficiency: U‑Channel, Angle, I‑Beam & H‑Beam, Hollow Section.
Quality Assurance, MTC & Inspections
Each lot ships with MTC (chemistry and basic mechanicals); dimensional checks include diameter/width, thickness, straightness and surface. Third‑party inspection (TPI) at mill/port on request; marking and traceability per contract.
Upstream casting context and production notes: Billet Grades and Wire Rod Production.
Supplier Selection Tips
Prioritize exporters with stable dimensional control, straightness and surface quality; confirm references into China. Trial parcels validate fit before larger agreements.

RFQ Checklist
- Define product: round or flat bar (or both).
- State sizes: diameter or width×thickness; confirm length (6/12 m or custom).
- Specify tolerances (straightness, twist) and surface (as‑rolled/peeled/ground).
- Choose Incoterms: CIF Tianjin (base); request CFR/CIF Shanghai comparison if needed.
- Clarify bundle weights/marking and any edge protection.
- Confirm QA scope (MTC, dimensional checks) and TPI if required.
- Provide monthly/annual tonnage and dispatch calendar; allow split lots if helpful.
