Q235B 角钢供应商

什么是 Q235B 角钢?

Q235B 角钢是一种由 Q235B 级低碳结构钢生产的 L 形热轧型材。牌号中的“Q”代表屈服强度(屈服),“235”表示厚度 ≤16 mm 的型材最小屈服点为 235 MPa,“B”表示 20°C 下的冲击试验保证。与 Q235A 相比,B 级具有更好的韧性,保证室温下夏比 V 型缺口冲击功 ≥27 J,使其适用于承受动态或循环载荷的结构。这种角钢广泛应用于钢结构、机械制造、造船和输电框架。

Q235B 角钢技术规格

我们的 Q235B 角钢严格按照 GB/T 706 的尺寸公差和 GB/T 700 的化学成分及力学性能生产。以下是关键技术参数:

性能规格
标准GB/T 700-2006(材质)/ GB/T 706-2016(尺寸)
屈服强度(≤16 mm)≥235 MPa
抗拉强度370–500 MPa
伸长率(A₅)≥26%
冲击功(20°C)≥27 J
碳含量≤0.20%
锰含量≤1.40%
密度7.85 g/cm³
等边规格20×20×3 mm 至 200×200×24 mm
不等边规格25×16×3 mm 至 200×125×18 mm
长度6 m、9 m、12 m 或定制
表面处理黑材、镀锌或按需涂漆

Q235B 角钢具有优异的焊接性——得益于其低碳当量(CEV ≤0.38%)——可直接进行电弧焊、气体保护焊和电阻焊,无需强制预热,显著缩短现场加工时间和成本。

Initial Dimension Issue Resolved Satisfactorily
Ordered 40 tonnes of Q235B unequal angle steel (160×100×14mm). Upon arrival, about 8% of the pieces had leg width tolerances slightly outside GB/T 706 limits. We flagged this immediately, and the supplier responded within 24 hours with a credit note and replacement shipment for the affected material at no extra cost. The replacement batch was perfect. Their willingness to resolve the issue quickly and professionally was reassuring. The remaining 92% of the original order was fully compliant and performed well in our bridge bracket application.

Decent Quality at Competitive Pricing – Minor Packaging Issue
Bought 30 tonnes of Q235B equal leg angles (80×80×8mm) for modular steel structure components. The steel quality itself was spot-on—yield strength, elongation, and surface finish all met expectations per GB/T 700. One bundle had slightly loose strapping upon arrival at port, though no material was actually damaged. For the price point, this represents excellent value compared to equivalent S235JR sections we've purchased from European mills. Would order again with a note to reinforce packaging.

Good Value for Large Volume Orders
Ordered 150 tonnes of Q235B angle steel (100×100×8mm, 12m lengths) for equipment frame fabrication. Mill-direct pricing was roughly 12% below what we were paying from domestic distributors for equivalent A36 material. Mechanical properties are comparable—tensile strength tested at 420 MPa on our end. Shipping took slightly longer than quoted (38 days vs 30), but the cost savings justified the wait. Quality documentation including MTC was thorough and our QA team accepted everything on first review.

Galvanized Q235B Angles Delivered on Time for Infrastructure Project
Sourced 200 tonnes of hot-dip galvanized Q235B angle steel (various sizes from 40×40×4mm to 200×200×20mm) for highway guardrail supports in Abu Dhabi. Galvanizing thickness met our specification, and the bundling/packaging was excellent—no transport damage despite the long sea freight. The supplier handled all export documentation professionally. Pricing was very competitive for this volume, and they offered flexible payment terms. Our project manager was impressed with the overall coordination.

Impact Test Results Verified – Solid B-Grade Material
We specifically needed Q235B (not A grade) for a dynamic loading application on conveyor support structures. Ordered 45 tonnes of 150×150×15mm equal leg angles with Charpy V-notch impact testing at 20°C. Lab results showed 34–38 J across all samples—comfortably above the 27 J minimum. The low carbon content (reported 0.17%) made arc welding straightforward for our workshop. Free samples were provided beforehand, which gave our engineers confidence before placing the full order.

Top-Notch Service and Consistent Quality
This is our third order in 18 months—this time 60 tonnes of Q235B angle steel in 50×50×5mm and 63×63×6mm for roof truss bracing on a commercial building in Melbourne. Every shipment has been consistent in quality with elongation values exceeding 26% as specified. Their 24/7 customer support is genuinely responsive; we once had a documentation query at midnight and got a reply within 30 minutes. Custom 9m lengths were delivered without any surcharge. Highly recommend for repeat procurement.

Reliable Mill-Direct Supplier for Warehouse Racking Frames
Purchased 85 tonnes of Q235B unequal leg angle steel (125×80×10mm) for industrial storage rack systems across three warehouse facilities. The dimensional tolerances met GB/T 706-2016 precisely—our fabrication team had zero fitting issues during assembly. The sales team provided detailed technical consultation on surface treatment options, and we opted for painted finish which arrived in perfect condition. Competitive mill-direct pricing made this 15% cheaper than our previous local sourcing.

Excellent Q235B Angle Steel for Transmission Tower Project
We ordered 120 tonnes of Q235B equal leg angle steel (75×75×8mm and 100×100×10mm) for a power transmission tower project in Wales. All material arrived with full mill test certificates per GB/T 700-2006, and our third-party inspector confirmed yield strength at 248 MPa—well above the 235 MPa minimum. Weldability was outstanding with no preheating required, which saved us significant fabrication time. Delivery to Felixstowe port took 32 days, exactly as quoted. Will definitely source our next batch from this supplier.
