The galvanized layer should be uniform without any missing spots or zinc lumps. The galvanized layer should comply with the corresponding national standards, such as the zinc layer not less than 250 grams/square meter. The thickness of the galvanized layer directly determines the anti-corrosion ability of the galvanized round steel.
Galvanized round steel is a geometric object made of iron or materials with certain strength and toughness through processes such as rolling, extrusion, casting, and hot-dip galvanized anti-corrosion profiles. Hot dip galvanized round steel is produced using advanced galvanizing technology, and its surface is glossy and durable. In suburban environments, the anti rust thickness of hot dip galvanized flat steel can be maintained for more than 50 years without the need for repair; In urban or offshore areas, the hot-dip galvanized anti rust layer of hot-dip galvanized flat steel can be maintained for 20 years without the need for repair; The galvanized layer thickness of hot-dip galvanized flat steel is uniform, up to 30-50um, with good reliability. The galvanized layer is metallurgical bonded with the steel and becomes a part of the steel surface, so the durability of the coating is relatively reliable; The toughness of the coating is strong, and the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
Galvanizing is also called Hot-dip galvanization: it is an effective way of metal corrosion prevention, mainly used on metal structures and facilities in various industries. It is to immerse the derusted steel parts in a molten zinc solution of about 500, so that a zinc layer is attached to the surface of the steel components, thereby achieving the purpose of anti-corrosion. Hot dip galvanized round steel refers to solid strip steel with a circular cross-section. Its specifications are expressed in millimeters of diameter, such as "50", which refers to a round steel with a diameter of 50 millimeters. The surface is treated with metal anti-corrosion after hot-dip galvanizing. With the discovery of industry, hot-dip galvanized round steel products have been applied in many fields. The advantage of hot-dip galvanized round steel is that it has a long anti-corrosion life and is widely adapted to the environment, which has always been a popular anti-corrosion treatment method. It is widely used in power towers, communication towers, railways, highway protection, street light poles, marine components, building steel structural components, substation ancillary facilities, light industry, etc.
