Manufacturing process: welded elliptical steel tube is made of steel plate, which is directly welded and formed after winding. The seamless elliptical steel tube is secondary shaped by pickling phosphating die. Welded elliptical steel tubes are mainly used in steel structure construction, such as bridge handrails, stair handrails, steel structure columns of large buildings and so on. Seamless elliptic steel tubes are mainly used for fluid transport, such as water, gas, steam, oil, oil and gas pipelines.

Galvalume Steel Coil is a kind of Alloy-Coated Steel Sheet widely used in building materials, household appliances,automobiles, environment, machinery, ships and many other fields. The surface coating of galvalume steel sheet is composed of 55% aluminium, 43.5% zinc and a small amount of other elements. 1. Heat reflectivity: Aluminum-coated galvanized steel sheet has a high thermal reflectivity, which is twice as high as galvanized steel sheet. It is often used as insulation material. 2. Heat resistance: Aluminum-zinc alloy steel sheet has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. 3. Corrosion resistance: The corrosion resistance of aluminized and galvanized steel coils is mainly due to the protective function of aluminium and aluminium. When zinc is abraded, aluminium forms a dense layer of alumina,which prevents further corrosion of corrosion-resistant substances. 4. Economy: Because the density of 55% Al-Zn is smaller than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of galvanized steel sheet under the same weight and thickness of gold plating. 5. Easy to paint: Aluminum-coated galvanized sheet and paint have excellent adhesion and can be painted without pretreatment and weathering treatment. 6. Aluminum-galvanized steel sheet has a silver-white gorgeous surface.
