什么是耐腐蚀钢筋材料?

耐腐蚀钢筋材料是专门配制或涂覆以抵抗混凝土结构内氧化、氯化物侵入和电化学降解的钢筋——或非金属等效物。常见产品系列包括 ASTM A1035 MMFX 铬合金钢筋、ASTM A955 不锈钢钢筋、ASTM A775 环氧涂层钢筋和 ASTM D7957 实心圆截面 GFRP 钢筋。每种变体在力学性能、使用寿命和安装成本之间提供了独特的平衡,适用于 ACI 318 和 AASHTO LRFD 桥梁设计标准所定义的不同暴露类别。

耐腐蚀钢筋材料技术规格

我们的库存涵盖多种牌号和尺寸,以满足不同项目的需求。所有产品均随附完整的钢厂测试报告(MTR),并可根据要求提供第三方检验证书。

产品类型 标准 屈服强度 抗拉强度 可供钢筋尺寸
MMFX 铬合金钢筋 ASTM A1035 Grade 100 690 MPa min. 830 MPa min. #3 – #18 (10–57 mm)
不锈钢钢筋 (316LN) ASTM A955 Grade 60 414 MPa min. 620 MPa min. #3 – #11 (10–36 mm)
环氧涂层钢筋 ASTM A775 / A934 420 MPa min. 620 MPa min. #3 – #11 (10–36 mm)
GFRP 钢筋 ASTM D7957 N/A (non-metallic) 690 MPa min. 6 mm – 32 mm diameter
镀锌钢筋 ASTM A767 Class I 420 MPa min. 620 MPa min. #3 – #11 (10–36 mm)

关键物理性能:在标准化氯化物积水试验中,MMFX 铬合金钢筋的腐蚀阈值约为传统黑钢筋的 10–12 倍。不锈钢变体保持钝化氧化层,316LN 合金的点蚀抗力当量数(PREN)超过 25,即使在直接海水暴露环境下也能确保卓越的防腐性能。GFRP 钢筋的密度为 2.1 g/cm³——约为钢材的四分之一——在大跨度桥面应用中可显著降低恒载。

Initial size mix-up on galvanized rebar order — resolved satisfactorily after follow-up
We ordered 30 tons of ASTM A767 Class I galvanized rebar split between #4 and #6 bars for a port quay wall in Mumbai. The first delivery contained an incorrect ratio — more #4 than specified in the purchase order. This created a short delay while we awaited the correct #6 quantity. To their credit, the supplier acknowledged the picking error quickly, arranged priority dispatch of the balance stock, and provided a partial credit on freight costs. Final material met the 420 MPa yield specification and zinc coating weight requirements per the MTRs. Issue resolved, and we would consider using them again with clearer order confirmation steps.

Competitive bulk pricing on epoxy-coated rebar — delivery slightly longer than quoted
Sourced 110 tons of ASTM A775 epoxy-coated rebar in #5 and #7 sizes for a multi-level car park in Sydney. The epoxy coating passed our holiday detection test on arrival and yield strength was confirmed at 420 MPa minimum per MTR. Bulk pricing was genuinely competitive — better than two other quotes we received. Only reason for 4 stars is that delivery arrived 3 days past the originally quoted window, which required us to adjust our pour schedule. The logistics team communicated the delay proactively, which we appreciated. Overall a solid supplier for large-volume ASTM-grade material.

Good value on MMFX rebar for tunnel lining — minor documentation gap resolved
Ordered 75 tons of ASTM A1035 Grade 100 MMFX rebar, sizes #4 to #9, for a road tunnel lining project near Frankfurt. Mechanical properties on the MTRs — 690 MPa yield, 830 MPa tensile — were fully compliant. Pricing undercut our local distributor by a meaningful margin for this volume. One item: the initial shipment was missing one batch's third-party inspection certificate, which caused a brief hold at our site QA stage. The supplier resolved it within 24 hours by sending the digital copy. Deducting one star for that, but the response was prompt and professional. Would order again.

Third repeat order — consistent quality across all three purchases
This is our third procurement from this supplier, covering epoxy-coated rebar to ASTM A775 and galvanized rebar to ASTM A767 Class I, totalling around 95 tons across three parking deck projects in London and Birmingham. Each order has arrived with matching MTR batches, consistent coating thickness measurements, and no holiday or adhesion failures on the epoxy bars. Pricing has remained stable even as market rates moved. The account manager proactively flagged a lead-time risk on our last order and helped us reschedule to avoid a delay. That kind of service keeps us coming back.

Excellent service for marine jetty project — stainless rebar delivered on tight schedule
We placed an urgent order for 60 tons of ASTM A955 stainless steel rebar (#3 to #7) for a marine jetty expansion in Abu Dhabi. The supplier confirmed stock availability within hours and dispatched documentation — MTRs, country of origin certificates, and third-party inspection reports — before the vessel booking was finalised. Customer support was reachable around the clock, which mattered given our time-sensitive pour window. Material quality passed our site QA inspection without any non-conformances. Will use for our upcoming desalination plant reinforcement.

Reliable GFRP rebar supply for long-span deck — dead-load savings confirmed
Procured 22 tons of ASTM D7957 GFRP rebar, 16 mm and 25 mm diameters, for a pedestrian bridge deck in the Northwest. The 2.1 g/cm³ density figure quoted matched the delivered product, and our structural engineer confirmed the dead-load reduction calculations were valid. Tensile strength certificates showed values well above the 690 MPa minimum. Delivery from order confirmation to site was 14 days. The pre-sales technical consultation helped us select the correct diameter substitution ratios versus conventional steel. Smooth transaction overall.

Stainless 316LN rebar with full ASTM A955 certification — technically impeccable
Our wastewater treatment facility project in Chennai required ASTM A955 Grade 60 stainless steel rebar (316LN alloy) in #4 and #6 sizes, roughly 45 tons total. The PREN values documented in the MTRs exceeded 25, satisfying our structural consultant's anti-corrosion threshold for direct chemical exposure zones. Third-party inspection certificates were provided proactively — no chasing required. Technical team responded to our specification queries within a few hours across time zones. Pricing was competitive given the grade. Highly recommended for critical infrastructure.

MMFX A1035 Grade 100 performed exactly as specified — outstanding corrosion resistance
We sourced approximately 180 metric tons of ASTM A1035 Grade 100 MMFX chromium-alloy rebar in sizes #5 through #8 for a coastal highway bridge rehabilitation in Florida. The mill test reports were clean and matched the 690 MPa minimum yield strength requirement without exception. Delivery to our Tampa yard took 11 business days, which kept our pour schedule intact. The chloride ponding data in the certification package aligned perfectly with what the spec engineer needed for the ACI 318 exposure category documentation. Will be back for Phase 2.
