Hot Sales Top Quality Dx52d Z140 Galvanized Steel Sheet for Building Iron Roof Sheet
Galvanized sheet is a kind of metal material that is coated with zinc on the surface of steel plate, mainly used to prevent steel corrosion and increase its durability. Galvanized sheet is usually a hot-dip galvanizing process, that is, the steel plate is immersed in a molten zinc solution to form a uniform zinc layer on its surface. This treatment can effectively prevent the steel from being eroded by air, water and chemicals, and extend its service life.
The advantages of galvanized sheet include good corrosion resistance, high strength and hardness, good processing performance and decorative performance. It is widely used in construction, furniture, automobile manufacturing, power equipment and other fields. In the construction industry, galvanized sheets are often used to make components such as roofs, walls, pipes and doors and Windows to improve their corrosion resistance and aesthetics. In the automotive industry, galvanized sheets are used to make body shells and components to increase their weather resistance and durability.
In general, galvanized sheet has good corrosion resistance and mechanical properties, is an important metal material, for protecting steel from corrosion and extending its service life plays an important role.
1. Corrosion resistance, paintability, formability and spot weldability.
2. It has a wide range of uses, mainly used for parts of small household appliances that require good appearance, but it is more expensive than SECC, so many manufacturers switch to SECC to save costs.
3. Divided by zinc: the size of the spangle and the thickness of the zinc layer can indicate the quality of the galvanizing, the smaller and thicker the better. Manufacturers can also add anti-fingerprint treatment. In addition, it can be distinguished by its coating, such as Z12, which means that the total amount of coating on both sides is 120g/mm.
Galvanized Steel Sheet and strip steel products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grids, etc.; the light industry industry uses it to manufacture home appliance shells, civil chimneys, kitchen utensils, etc., and the automobile industry is mainly used to manufacture corrosion-resistant parts of cars, etc. ; Agriculture, animal husbandry and fishery are mainly used for grain storage and transportation, frozen meat and aquatic products, etc.; commercial is mainly used for storage and transportation of materials, packaging equipment, etc.

Standard packaging for Galvanized Steel Plate can vary depending on a number of factors including manufacturer, sheet size and quantity. However, most manufacturers typically package GI sheets in bundles, usually 10 to 100 pieces, with each bundle wrapped in plastic or metal straps for extra protection during transport.
Additionally, some manufacturers may provide further protection by placing the package in a wooden box or wrapping the package in plastic or cardboard. Packaging may also include labels or markings indicating dimensions, specifications, and other pertinent information about the GI form.
It's important to note that standard packaging may not be suitable for all types of shipping or storage, especially if the sheets are exposed to extreme weather conditions or rough handling. In such cases, additional measures such as cushioning, insulation, or special containers may be required to keep the sheets safe.
