Galvanized Steel Pipes and Tubes

During galvanizing, steel is immersed in a molten zinc bath, ensuring a tough, uniform barrier coating.

锌的天然耐腐蚀性提供了长期保护，即使在室外环境中也是如此。除了防水腐蚀之外，它在干燥，室内环境中同样有效。

镀锌钢管和由镀锌钢制成的管长期以来一直是世界上最常用的建筑材料之一。几十年来，在户外应用中寻求长期结构性能的设计师，建筑商和消费者已经转向镀锌钢管。镀锌镀锌钢管和管抵抗风，水和道路盐的攻击。

Galvanizing alloy layer mainly depends on the thickness of the silicon content of the steel chemical composition, the rough degree of the size of the cross-sectional area of the steel surface of the steel, the temperature of the zinc pot, the zinc immersion time, the cooling speed, and the cold deformation.

Hot-galvanized advantages

• 低成本的公关ocessing: hot-dip galvanized anti-rust lower cost than the cost of other paint coating;
• 耐用：标准热浸镀锌防锈厚度可在农村环境中保持50岁以上，无需补丁;标准热浸镀锌防锈层可以在城市地区或离岸地区保持20年，而无需补丁;
• good reliability: galvanized layer with steel is metallurgically bonded to become a part of the surface of the steel, and therefore more reliable coating persistent;
• the toughness of the coating: zinc coating to form a special metallurgical structure, this structure can withstand transportation and use of mechanical damage;
• 全面防护：镀敷件可以用锌电镀，即使在凹槽中，尖角和隐藏的地方也可以完全保护;
• 节省时间和精力：镀锌过程比其他涂层施工方法快，并且可以避免安装后现场所需的刷牙时间。
