Product Overview Galvalume steel sheets have a coating composition of 55% aluminum, 43.5% zinc, and 1.5% silicon. They exhibit excellent resistance to atmospheric corrosion, with their corrosion resistance being 2-4 times that of galvanized steel sheets at the same coating thickness. Meanwhile, they also possess the high-temperature corrosion resistance of aluminum sheets. Product Specifications Lines： Galvalume Steel Coil Thickness (mm)： TC 0.2-1.2 Width (mm)： 800-1260 Coil weight (MT)： 3.0-8.0 Zinc coating： 30-220 g/㎡ Painting： 0.5-1.5μm Coating Composition： 55% Aluminum - 43.5% Zinc - 1.5% Silicon Strength： G250/G280/G300/G350/G550/ DX51D/DX52D MOQ: 32 tons per size Payment term： T/T; L/C at sight Quality Assurance Product Advantages Small dendrites space distance With unique formula of the coating and control of coating thickness, the dendrite spacing of Shinmade galvalume steel is 10-15μm under electron microscopy, and the corrosion resistance of the product is excellent. Coating cross-sectional structure - optical microstructure The coating structure of Shinmade’s products is a staggered skeleton, which has good density and can prevent the intrusion of rainwater and other corrosive media, and that is why the product has good corrosion resistance. If the coating structure is bamboo-like, which means the coating layer is not dense enough and the corrosion resistance can be poor. Small-sized and uniform spangle The stability of crystallization determines the size and uniformity of spangles. The spangles are precisely controlled under the combined effects of the steel strip temperature, zinc liquid temperature, surface roughness, post-plating cooling, and special coating formula. The diameter of the spangle of Shinmade's galvalume is controlled between 0.5-3mm, which means the spangles are small-sized and uniform, and the appearance effect is more stable. Chromate/Passivation+AFP We adopt double-coating and baking process for post-treatment, which means we first to passivate, dry and cool the sheets, next to apply AFP coating on the sheets and dry and cool. The AFP film is thicker and cured better, so the processing lubricity is relatively better. Applications Construction industry： Roofs, exterior walls, color - coated substrates, garage doors, fences, shutters, ventilation ducts of civil and industrial buildings, etc. Industrial instrumentation： Electric control cabinets, industrial freezers, vending machines, etc. Home appliance industry： Washing machines, refrigerators, televisions, air conditioners, ovens, outer covers of ventilation systems, explosion - proof strip steel, solar water heaters, electrical components, etc. Other industries： Automobile mufflers, heat shields for exhaust pipes and catalytic converters, parts at the bottom of automobile bodies, highway signs, car horns, small hardware, etc. Production Lines Shinmade owns 2 galvalume production lines with an annual designed production capacity of 550,000 tons. 1、Siemens electrical control system 2、German EMG correction CPC/EPC system 3、9-stage cleaning system 4、Ultra-long horizontal annealing furnace 5、Advanced air knife system 6、Online X-Ray coating thickness measurement gauge 7、Wet finishing design (skin- pass strength 5000kN） 8、Double-bending and tension-leveling ( wet leveling and straightening )process 9、Double coating (passivate and AFP) and baking configuration FAQ Q: What types of steel coils do you supply? We offer a wide range of coils including GL, PPGL, and CR. Q: Can I customize the coil specifications ? Yes. We support full customization of thickness, width, coating weight, paint color, and surface finish based on your specific requirements. Q: What is the minimum order quantity ?

Product Overview Zinc - aluminum - magnesium products are usually classified into three categories according to the aluminum content in the coating: low - aluminum products, medium - aluminum products, and high - aluminum products.They are characterized by high corrosion resistance and high cut - edge protection. Product Specifications Item： Details Coating Composition： 53% Aluminum - 43.4% Zinc - 1.6% Silicon - 2% Mg Coating Thickness： AM60 - AM200 Product Thickness： 0.15 - 1.60 mm Product Width： 700 - 1260 mm Product Advantages Mechanism of Corrosion Resistance A large number of experiments verify that AZM products have excellent corrosion resistance and are the trend in the construction field. The reasons are as follows: · Zinc provides sacrificial protection; · Aluminum provides passivation protection; · Magnesium,together with zinc and aluminum are to reduce the consumption rate of the coating; · Mg2Si formed below the coating provides barrier protection inside the coating. Ten-week cyclic Q-Fog test (Q-fog CCT) After 10 weeks of cyclic corrosion comparison experiments, there was no obvious change on the surface of the Al-Zn-Mg samples (AM150 gsm and AM100 gsm), a little red rust appeared on the surface of the galvalume sample (AZ150 gsm), and a large area of rust appeared on the surface of the galvalume sample (AZ100 gsm). Eleven-month marine environment exposure After 11 months of marine environment exposure experiments, there was no obvious change on the surface of the PPAM (AM50 gsm) sample, while salt frost appeared locally on the surface of the PPGL (AZ50 gsm)sample. Fourteen-month outdoor acid rain environment exposure After 14 months of exposure to outdoor acid rain environment, there was no obvious change on the surface of the Al-Zn-Mg samples (AM150 gsm and AM100 gsm), but the surface of the galvalume sample (AZ150 gsm) began to rust, and the surface of the galvalume sample (AZ100 gsm) had been rusted over a large area.
