什么是冷轧镀铝锌卷?

冷轧镀铝锌卷是一种金属涂层钢板产品,通过连续热浸镀锌线在冷轧钢基材上施加55%铝、43.4%锌和1.6%硅合金涂层制成。这种先进的涂层技术与传统镀锌钢相比,耐腐蚀性提高三到六倍,涂层重量通常按ASTM A792/A792M标准在AZ50至AZ185(150-550 g/m²)范围内。

冷轧镀铝锌卷技术规格

我们的冷轧镀铝锌卷符合ASTM A792/A792M-17 Grade 50要求,基体金属厚度从0.15mm到2.0mm,卷宽可达1,500mm,屈服强度最低345 MPa。涂层结构由提供耐大气腐蚀性的富铝外层和提供电化学保护的富锌内层组成,总涂层重量选项包括AZ50、AZ70、AZ100、AZ150和AZ185牌号,满足商业级和结构级规格要求。

为什么选择我们的冷轧镀铝锌卷

我们拥有通过 ISO 9001:2015 认证的生产设施,配备最先进的连续镀铝锌涂层生产线,年加工能力达 500,000 公吨。我们的钢厂直销定价消除了中间商加价,同时通过炉号文件、按 ASTM A924 表面质量标准出具的第三方检验报告,以及按 ASTM E1086 光电发射光谱分析确认化学成分的材料测试证书,确保全程可追溯性。

常见问题

最小起订量(MOQ)是多少?

我们的标准最小起订量为每规格 25 公吨,但对于建立供应关系的新客户,我们也可承接 10 吨的较小试订单。对于同一合金牌号下组合多种厚度或镀层重量的订单,可提供混装集装箱装载。

你们提供材料测试证书吗?

是的,我们为每批卷材发货提供符合 EN 10204 Type 3.1 文件的综合工厂测试证书,包括化学成分分析、力学性能测试结果、按 ASTM A90 三点测试法进行的镀层重量验证,以及确认符合 ASTM A924 表面处理代号要求的表面质量检验报告。

典型交货时间是多少?

对于库存规格订单,标准交货期为收到定金后 25-30 个日历日;而定制厚度或镀层重量要求可能根据生产排程延长至 35-40 天。对于紧急项目,在提出请求并确认产能可用性的情况下,可提供 15 天交货的加急处理。

你们能按定制尺寸切割吗?

我们的精密纵剪生产线可进行50mm至1,500mm的定制宽度剪切,公差为±2mm,而定尺剪切服务可根据ASTM A1063尺寸要求提供1,000mm至6,000mm的剪切平板。我们还提供纵向边缘修整,达到规定的侧弯公差,以满足对平整度特性有极高要求的关键建筑应用。

Acceptable Quality with Initial Documentation Delay
Ordered 15 tons of 0.6mm galvalume coil, AZ150 coating for marine container modification project. Material quality meets ASTM A792 specifications and coating weight verified at 485 g/m². Initial shipment arrived without mill test certificates, causing 5-day project delay. Supplier expedited documentation via courier and provided additional third-party inspection report as compensation. Material performance in salt environment satisfactory after 60 days testing.

Reliable Material with Consistent Properties
Purchased 20 tons of 0.55mm cold rolled galvalume, AZ120 coating for industrial equipment housings. Mechanical properties consistent across all coils: yield strength 348-355 MPa range. Surface finish quality suitable for powder coating application. Compared quotes from 5 European suppliers - this offered best value. Packaging could be improved as outer wrap had minor moisture damage, but coils themselves unaffected.
