镀铝锌钢卷 - ASTM A792 热浸镀锌铝锌合金涂层

Galvalume 钢卷是一种优质金属涂层钢产品,采用热浸镀铝锌合金涂层,具有卓越的耐腐蚀性和热反射性。这种先进的涂层钢专为屋面、墙板和建筑应用而设计,结合了铝的屏障保护与锌的牺牲阳极保护,在沿海、工业和农业环境中提供卓越性能。我们的 Galvalume 钢卷按照 ASTM A792/A792M 标准制造,服务于寻求长期耐久性和最低维护要求的建筑承包商、金属建筑制造商和屋面专业人员。

什么是 Galvalume 钢卷?

Galvalume 钢卷是一种冷轧碳钢基材,涂覆有按重量计由 55% 铝、43.4% 锌和 1.6% 硅组成的铝锌合金。这种专有涂层通过连续热浸工艺在超过 600°C 的温度下施加,与钢基体形成冶金结合。独特的合金成分同时提供铝的屏障保护和锌的牺牲保护,在大多数大气环境中,其耐腐蚀性比传统镀锌钢高达四倍。

Galvalume 钢卷技术规格

我们的镀铝锌钢卷符合 ASTM A792/A792M-20 第 6 节要求,镀层牌号为 AZ50 至 AZ185(每面镀层重量为 0.50 至 1.85 oz/ft²)。基材由商业质量 (CQ)、深冲质量 (DQ) 或结构质量 (SS Grade 33-80) 钢组成,厚度范围为 0.0142 至 0.0897 英寸(0.36 至 2.28 mm)。每面镀层厚度为 0.0008 至 0.0030 英寸(20 至 76 微米),根据 ASTM A792 表 3 提供最小锌花等级。抗拉强度根据所选等级从 33,000 至 80,000 psi 不等,屈服强度根据 ASTM A653/A653M 结构要求从 33,000 至 70,000 psi 不等。

为什么选择我们的镀铝锌钢卷

我们的钢厂直供镀铝锌钢卷提供具有成本效益的解决方案,并附有全面的质量认证,包括符合 ASTM A792 第 17 节的工厂测试报告和 ISO 9001:2015 制造标准。我们备有大量 AZ50、AZ55 和 AZ70 镀层重量、24 至 72 英寸标准卷宽的库存,能够快速满足大型建筑项目和定制加工需求。我们的技术支持团队提供镀层选择指导、成形性分析和涂装系统兼容性建议,以优化您特定应用环境中的性能。

常见问题

最小起订量 (MOQ) 是多少?

我们的镀铝锌钢卷标准最小起订量为每规格25公吨,但我们也接受试订单或定制镀层重量的较小数量。可以安排混合集装箱装载,组合不同厚度或宽度,以满足您20英尺集装箱约22-24吨的容量,从而灵活应对多样化项目需求,避免库存过剩。

你们提供材质测试证书吗?

是的,我们为每卷提供符合EN 10204 Type 3.1文件的综合工厂测试证书(MTC),包括按ASTM E415进行的化学成分分析、按ASTM A90进行的镀层重量验证,以及按ASTM A370进行的力学性能测试。可根据您的要求安排通过SGS、BV或Intertek进行的额外第三方检验服务,报告涵盖尺寸公差、表面质量评估以及按ASTM D3359进行的镀层附着力测试。

典型交货时间是多少?

对于标准规格(AZ50-AZ70镀层、0.0179-0.0478英寸厚度、48英寸宽度),我们的交货时间是从收到定金到FOB装运港25-30天。定制镀层重量、非标准宽度或特定基板等级可能需要35-45天生产周期。我们在主要港口维持战略仓库库存,使常用规格可实现7-10天交货,并在询价时提供实时库存情况。

你们可以按定制尺寸切割吗?

当然可以。我们的加工厂提供精密纵剪服务,可定制宽度,公差为 ±0.0625 英寸,并提供定尺剪切加工,适用于长度从 48 到 240 英寸的板材。我们提供边缘处理选项,包括去毛刺边缘、圆角和保护性边缘涂层,以防止搬运损伤。每个宽度规格的最低加工数量为 5 吨,合并订单可享受降低的加工费用。

Premium Performance in Marine Environment - Third Order
This is our third order totaling 85 tons over 14 months for marina projects in Queensland. Latest shipment was 30 tons of AZ70 coating (0.0418 inch thickness, 48-inch width). Corrosion resistance testing shows performance 4x better than standard galvanized steel in salt spray environment. Warehouse stock availability enabled 9-day delivery for urgent project requirements. Consistent quality across all three orders. Established relationship with their technical team invaluable for material selection guidance.

Acceptable Quality with Initial Documentation Delay
Purchased 22 tons of AZ55 coating for agricultural siding project. Material quality was acceptable once received, meeting ASTM A792 standards. However, mill test certificates were delayed by 5 days after shipment arrival, causing project scheduling issues. Coating weight verification showed 0.54 oz/ft², within tolerance. Supplier resolved documentation issue and provided discount on next order. Material performed well during fabrication with good formability.

Superior Coating Uniformity for Architectural Panels
Ordered 18 tons with custom cut-to-length processing (96-inch sheets, 0.0209 inch thickness). Spangle pattern was remarkably uniform across all sheets, critical for our exposed architectural application. Chemical composition analysis per ASTM E415 showed silicon at 1.58%, within specification range. Edge conditioning with deburred finish prevented handling damage during installation. Delivered in 29 days with SGS inspection report. Premium quality justified the investment.

Reliable AZ70 Coils for Desert Climate
Sourced 35 tons of AZ70 coating (0.0359 inch thickness, 54-inch width) for metal building project in Abu Dhabi. Compared quotes from 4 suppliers before selecting this one. Coating thickness measured at 0.0026 inches per side, providing enhanced corrosion protection for harsh desert environment. Delivery took 33 days, slightly longer than quoted 28 days. Material quality excellent but communication could improve during production phase.

Good Value Material with Competitive Pricing
Purchased 40 tons of AZ50 coating (0.0299 inch thickness, 60-inch width) for industrial roofing project. Price was 12% lower than local suppliers while meeting ASTM A792 standards. Coating adhesion tested per ASTM D3359 showed excellent results. Minor edge waviness on 2 coils but within tolerance. Overall good quality for the price point. Would order again for cost-sensitive projects.
