什么是扁钢?

扁钢是一种通过热轧或冷拔工艺制造的实心矩形型材钢产品。扁钢以其宽厚比(通常大于 2:1)为定义特征,与钢板的不同在于其宽度更窄,与方钢的不同在于其横截面尺寸不相等。热轧扁钢具有典型的轧制氧化皮表面,公差符合 ASTM A29(宽度小于 75 mm 时为 ±0.4 mm),而冷拔扁钢则可达到 ±0.1 mm 的更严格尺寸公差,并具有光滑明亮的表面光洁度,非常适合精密应用。常见等级包括 A36(屈服强度最低 250 MPa)、A572 Grade 50(屈服强度最低 345 MPa)和 1045 中碳钢(抗拉强度最低 585 MPa)。

扁钢库存技术规格

我们的扁钢库存涵盖工业需求的全部范围。以下是关键技术参数:

扁钢制造商

  • 材质牌号: ASTM A36, A572 Gr.50, 1018, 1045, 4140, SS 304/316, Q235B, Q345B, S235JR, S355JR
  • 厚度范围: 3 mm – 200 mm
  • 宽度范围: 10 mm – 600 mm
  • 标准长度: 6 m, 9 m, 12 m,或定尺切割
  • 表面处理: 热轧(氧化皮)、冷拔(光亮)、镀锌或涂漆
  • 公差: 热轧按 EN 10058 / ASTM A29;冷拔按 ASTM A108(公差等级 CF)
  • 密度: 碳钢 7.85 g/cm³;304 不锈钢在 20°C 时为 7.93 g/cm³
  • 年产能: 150,000 公吨

热轧扁钢在结构支撑、底板、拖车制造和农业设备中发挥着关键作用。冷拔扁钢广泛应用于模具键、机床导轨、锁具部件和建筑装饰条,这些领域对尺寸精度和优异表面质量有着不可妥协的要求。304(含 18% 铬和 8% 镍)和 316(含 2% 钼)牌号的不锈钢扁钢为化学加工、船舶五金和食品级设备制造提供出色的抗腐蚀性能。

Minor Thickness Variation Resolved After Communication
Ordered 18 tons of hot rolled flat bar in Q235B, 16mm x 120mm x 12m, for base plates in an industrial shed project. On arrival in Chennai, we found about 15% of bars had thickness running 16.6–16.8mm — slightly outside the EN 10058 tolerance for that size. We raised the issue with photos and measurements. The supplier responded within 24 hours, offered a fair credit note, and tightened QC checks for our next shipment. Second batch came through perfectly at 16.0–16.3mm. Appreciated the honest resolution. Continuing to work with them.

Decent Cold Drawn Flat Bar for Architectural Trim Work
We ordered 5 tons of cold drawn 1018 flat bar (6mm x 30mm, 6m lengths) for architectural trim and decorative metalwork. Surface quality was good — bright and smooth enough for our finishing process without heavy prep work. Dimensional consistency was reliable across the batch. Price per ton was very competitive compared to UK domestic stock. Shipping to Felixstowe took 41 days, slightly longer than the 35 days estimated, but not a dealbreaker. Would recommend for projects where cost efficiency matters alongside reasonable quality.

Good Value on Galvanized Flat Bars for Construction Projects
Bought 30 tons of galvanized flat bars in S235JR grade, 8mm x 40mm and 10mm x 50mm, for construction projects across Dubai and Abu Dhabi. Zinc coating thickness averaged 78 microns — adequate for our outdoor exposure requirements. Pricing was about 12% below what we were paying our previous European supplier for comparable quality. Two bundles had minor labeling mix-ups between the two sizes, but the warehouse sorted it quickly. Overall a solid deal and we've already placed a follow-up order for S355JR material.

Third Order This Year — Consistently Good Flat Bar Stock
This is our third purchase in 2025 — we keep coming back because quality and pricing are consistently strong. Latest order was 55 tons of Q345B flat bars (30mm x 200mm x 9m) for resale to our fabrication clients. Every heat number matched the MTCs. Our customers have had zero complaints about dimensional accuracy or mechanical properties. Pricing stayed competitive even with recent raw material fluctuations. The dedicated account manager remembers our specs and preferences, which speeds up repeat ordering significantly.

Great Service and Quality for Trailer Build Flat Bars
Ordered 22 tons of A36 hot rolled flat bar in mixed sizes — 10mm x 50mm and 12mm x 75mm — for our trailer manufacturing line in Melbourne. The sales team helped us optimize the loading plan to fit two sizes in one 40ft container, saving us on freight. Weldability was excellent with no cracking issues. Surface had standard mill scale that cleaned up easily. Free samples arrived before we committed to the full order, which gave us confidence. Responsive 24/7 support made the time zone difference a non-issue.

Reliable SS 316 Flat Bar Supply for Chemical Equipment
We sourced 12 tons of SS 316 flat bars (15mm x 100mm, 6m lengths) for chemical processing equipment frames. The 2% molybdenum content was verified through our own spectrometer analysis. Corrosion resistance testing in chloride solution showed excellent results. Material certificates aligned with EN 10088-3 requirements. Cut-to-length accuracy was impressive. Our production team reported zero rejections during fabrication. Delivery to Hamburg was on schedule at 38 days. Will continue this partnership.

Cold Drawn 1045 Flat Bar — Superb Surface Finish
Purchased 8 tons of cold drawn 1045 flat steel, 20mm x 60mm, for CNC machined die keys and machine guides. The bright surface finish was flawless — no additional grinding needed before machining. Tolerances measured at ±0.08mm, tighter than the ±0.1mm promised. Tensile strength on our test coupons came back at 602 MPa. Packaging was proper with anti-rust oil and bundled securely. Technical team answered our metallurgy questions within hours. Very professional operation.

Excellent A572 Gr.50 Flat Bars for Structural Bracing
We ordered 40 metric tons of A572 Grade 50 hot rolled flat bars, 25mm x 150mm x 12m lengths, for a commercial building bracing project in Texas. Yield strength tested at 358 MPa — well above the 345 MPa minimum. Dimensional tolerances were within ASTM A29 specs across every bundle. Mill test certificates were provided promptly. Delivery to Houston port took 32 days, which was faster than quoted. Already planning our next order for Q4. This supplier understands what structural fabricators need.
