PPGL is the abbreviation of pre-painted galvalume steel which uses the galvalume steel as its base metal and painted with various types of painting like PE/HDP/SMP/PVDF, etc. With excellent corrosion-resistance and aesthetic beauty, they are mainly used in bulding industries as wall panels,metal roofing and sandwhich panels, etc.
Galvalume, also known as Al-Zn alloy coated steel, is an anti-corrosion steel material composed of 55% Al, 43.4% Zn, and 1.6% Si. It has excellent corrosion resistance, 2-4 times that of galvanized steel. It also qualifies some features of aluminum sheet, like the high-temperature corrosion resistance, smooth surface, and good appearance. Application: They can be used as some architectural materials, like roofing, wall panels, and the substrate of color-coated steel; they can also be used as some parts in elevators, automobiles, and lights.
The steel plate with zinc-aluminum-magnesium coating refers to the coated steel plate in which a certain amount of Al and Mg are added to the existing hot-dip galvanized coating, or a certain amount of Mg element is added to the hot-dip aluminum-zinc coating. It has the characteristics of high corrosion resistance and high edge protection performance. The results of publicly disclosed laboratory acceleration experiments, outdoor exposure experiments, etc. show that within a certain range, the increase in the content of Al and Mg can improve the corrosion resistance by several times to more than ten times. Another major advantage after adding Mg to the coating is the improvement of the corrosion resistance of the cut edge of the steel plate. The Zn-based corrosion products containing Mg will cover the surface of the cut, thus forming protection for the cut. Applications: Building roofs, walls, agriculture and animal husbandry, home appliances, automobiles, substrates for color coating, etc.
Cold-rolled steel sheets have good properties. We can get the cold-rolled steel sheets with thinner thickness and better tolerance control by rolling the hot-rolled steel sheets. With high flatness, gloss and bright surface,cold-rolled steel sheets are easier to be coated and processed. Cold-rolled steel sheets are mainly used in the packaging industry and used as the substrates of galvanized steel sheets, galvalume steel sheets and Zn-Al-Mg alloy coated sheets. Shinmade has 7 cold-rolled production lines with an annual capacity of 1.4 million tons. The production specification ranges from 600-1300mm in width, 0.06-2.0mm in thickness with a tolerance of ±0.01mm. The production lines are equipped with Fuzzy shape control systems, the shape measuring rollers made by ABB in Switzerland, R-700 PLC systems developed by Hitachi, and advanced PCS7 thickness control systems of Siemens.
Shinmade products can be used in industrial plants, gymnasiums, airports, stations, indoor partitions, warehouses, elevators, metal curtain walls and other places, and are exported to more than 20 countries and regions.
