建筑用不同尺寸的钢筋 - 工厂直供

了解建筑用不同规格的钢筋,对于要求结构完整性和长期耐久性的工程师、承包商和采购专家来说至关重要。钢筋——通常称为 rebar——是嵌入混凝土结构中的抗拉骨架,弥补了混凝土在受拉状态下固有的弱点。从住宅地基到桥梁、水坝和高层建筑等大型基础设施项目,选择正确的钢筋直径和等级直接决定了承载能力和使用寿命。作为钢厂直供供应商,我们提供符合 ASTM A615、BS 4449 和 GB/T 1499.2 标准的全系列钢筋规格,确保每个项目——无论规模或复杂程度如何——都能获得所需的精确规格。我们的库存涵盖从 #3(9.5 mm)到 #18(57.3 mm)的标准带肋钢筋,并可根据要求提供定制长度和盘卷选项。

建筑用不同规格的钢筋有哪些?

建筑用不同规格的钢筋是指按公称直径、横截面积和单位重量分类的标准化带肋或光圆钢筋系列。每种规格标识——无论以英制钢筋编号(#3 至 #18)还是公制直径(6 mm 至 50 mm)表示——都对应特定的力学性能和结构应用。钢筋通常由碳钢或低合金钢制造,表面带有横肋,可增强与混凝土的机械咬合,防止在荷载作用下发生滑移。

建筑用不同规格的钢筋——技术规格

我们的钢厂直供螺纹钢库存涵盖现代建筑所需的全部尺寸范围。每种规格的抗屈强度最低为420 MPa(符合ASTM A615标准Grade 60),抗拉强度最低为620 MPa,8英寸标距内的延伸率不低于9%。表面变形高度和间距符合ASTM A615表1的要求,确保所有直径下粘结性能一致。

Quality fine, but initial paperwork gap caused site hold-up — issue now fully resolved
We ordered 50 tonnes of #5 (15.9 mm) rebar to BS 4449 Grade B500B for a retaining wall scheme in Manchester. The steel itself met spec — cross-sectional area 200 mm², yield strength compliant — and the 9 m cut lengths were accurate. However, the EN 10204 3.1 inspection certificate was missing from the first shipment, which caused a two-day hold while our structural engineer waited for documentation. After escalating to the technical team, the full certificate pack was emailed within hours and a hard copy followed by courier. The supplier acknowledged the process gap and confirmed a documentation checklist is now in place. Satisfied with how it was handled and open to reordering.

Competitive mill-direct pricing on #7 and #8 bars — delivery slightly longer than quoted
We procured 140 tonnes of #7 (22.2 mm) and #8 (25.4 mm) deformed rebar for column and pier reinforcement on a mid-rise residential tower in Dubai. The material quality was strong — tensile strength above 620 MPa, clean surface deformation, and mill test reports aligned with ASTM A615 Grade 60. Mill-direct pricing gave us a meaningful margin advantage. My only reservation is that the actual delivery to Jebel Ali port took 28 days versus the 21 days initially indicated. The team communicated the delay proactively and it didn't derail our schedule, but tighter lead time accuracy would earn a fifth star.

Good value on #3 and #4 rebar for slab work — minor labelling issue resolved
Ordered 75 tonnes of #3 (9.5 mm) and #4 (12.7 mm) bars for a series of residential slabs and sidewalk projects in Florida. The steel quality itself was solid — ASTM A615 Grade 60 compliance confirmed, unit weights of 0.560 and 0.994 kg/m spot-on. Pricing was genuinely competitive against local distributors. I'm giving 4 stars rather than 5 because a small number of bundles arrived with unclear heat number tags, which slowed our incoming QC. The supplier sent corrected documentation within 48 hours and the issue hasn't recurred. Overall a reliable source for standard sizes and would use again.

Third repeat order — consistent quality on #4 and #5 bars across all batches
This is our third procurement from this supplier, totalling over 500 tonnes of #4 (12.7 mm) and #5 (15.9 mm) rebar for residential foundation work across Queensland. Consistency between batches is what keeps us coming back — yield strength, elongation, and deformation geometry are virtually identical heat to heat. ASTM A615 Grade 60 certification is provided without having to chase it. The free sample process before our first order gave us confidence. Bulk pricing improves with each order, and the account manager proactively flags lead time changes. No surprises, which in our industry is exactly what you want.

Epoxy-coated #6 rebar for marine foundation — corrosion protection met spec
Our project involved caisson foundations in a tidal zone near Hamburg, so we required epoxy-coated #6 (19.1 mm) rebar with zinc coating weight ≥305 g/m² per ASTM A767. The supplier provided third-party coating thickness reports alongside the standard mill test reports, which satisfied our client's independent inspector. We took 60 tonnes across two shipments. Coating adhesion and continuity were verified on arrival with a holiday detector — zero defects found. Unit weight at 2.235 kg/m matched spec precisely. Pricing for coated product was competitive versus European stockists. Solid technical partner for specialist applications.

Responsive service and clean documentation for BS 4449 Grade B500B bars
Placed an order for 95 tonnes of 16 mm and 20 mm deformed rebar to BS 4449 Grade B500B for a commercial retail development in Birmingham. What stood out was how quickly the team responded — quote within 4 hours, full documentation pack including EN 10080 compliance certificates within 24 hours. Bars arrived in 12 m mill lengths as specified, with no short lengths in the bundles. The 24/7 support line was genuinely useful when we needed to adjust the delivery schedule at short notice. Quality control on the surface deformation pattern was excellent. Will reorder for Phase 2.

Mill-direct pricing on #5 and #6 rebar made our housing project viable
Sourced 320 tonnes of #5 (15.9 mm) and #6 (19.1 mm) deformed bars for a 200-unit residential complex in Pune. The bars comply with both ASTM A615 and our local IS 1786 Fe500D equivalent requirements, and the surface rib geometry was consistent throughout. Cross-sectional area measurements matched the spec sheet exactly — 200 mm² and 284 mm² respectively. Mill-direct rates were noticeably lower than local distributors. Lead time was 18 days to Mumbai port. Technical consultation before ordering helped us finalise the grade-diameter mix without over-specifying. Highly recommend for volume procurement.

Precise #8 and #10 rebar specs — exactly what our bridge project demanded
We ordered 180 tonnes of #8 (25.4 mm) and #10 (32.3 mm) deformed rebar conforming to ASTM A615 Grade 60 for a large-span bridge deck rehabilitation. The certified mill test reports confirmed yield strength well above 420 MPa and elongation exceeding 9%. Dimensional tolerances were tight across every bundle we checked. Delivery to our Houston yard took 22 days from order confirmation — well within our schedule. The technical team reviewed our structural drawings and recommended the optimal diameter combination, saving us roughly 8% on material cost. Will be our go-to supplier for future infrastructure work.
