Cold Rolled Mild Steel Strip

Pre-painted galvanized steel combines utility with beauty. It consists of tin, chrome, zinc or paint, which are the extra finish applied to the natural steel surface. The application of coating is to protect the surface of steel from oxidation and it is also used to enhance requirements for visual appearance.

Galvanized steel is a hot-dipped coated metal that provides customers with better resistance to corrosive environments. To create galvanized steel, cold rolled steel is submerged into a molten zinc bath, known as the hot-dip process (galvanization can also be achieved through continuous galvanizing). When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs. The reaction causes the zinc coating to become part of the steel creating the well-recognized spangled finish.

Galvanized coil: a thin steel sheet that immerses the steel sheet into the molten zinc bath to make its surface adhere with a layer of zinc. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate; Alloyed galvanized steel sheet. This kind of steel plate is also made by hot dip method, but it is heated to about 500 ℃ immediately after coming out of the groove to form an alloy coating of zinc and iron. The galvanized coil has good coating adhesion and weldability.

304 Stainless Steel is the most widely used of the austenitic (chromium/nickel) stainless steels. In the annealed condition it is essentially non-magnetic and becomes slightly magnetic with the application of cold work. Type 304L Stainless Steel is preferred in welding applications to exclude the formation of chromium carbides during cooling in the heat affected region of the weld. These alloys represent an excellent combination of corrosion resistance and fabricability.

Aluminum zinc coated steel coil is proceeding by dipping aluminum and zinc on the surface of cold rolled steel sheet.

Galvanized iron sheet is a material consisting of a zinc layer applied to sheets of metal that go through a process called “Hot-Dipping”, in which the metal sheets go through a molten zinc bath. The zinc then bonds to the iron particles within the steel sheet and forms a protective layer on both sides. Hot-Dipping is a process that helps protect metal materials such as steel sheets from corrosion caused by potential exposure to extreme environments. This is achieved through multiple processing types and it protects materials over a long time from degrading whilst maintaining their original properties unaltered.

The coated steel sheet we make into our roof cladding are produced in accordance with a strict series of quality standards by leading suppliers, giving us traceability and quality control. The durability of this roof cladding material is dependent on the galvanised and protective coatings applied to roofing substrate and fenicing substrate. As a roofing sheets material, steel has long been used in building and has the added benefit of being recyclable. To produce our high quality pre-coated roof cladding sheets, a system of multi-layer coatings is applied to the zinc-coated high tensile steel strip and then oven-cured to ensure optimum adhesion. This gives roofing sheets with excellent corrosion resistance and climatic protection together with abrasion resistance and a strong structure.
