Why choose ZM coated steel as best choice for C type steel ballasted roof mounting system?
As the topic of environmental protection continue to be mentioned and the world vigorously advocates, the solar energy industry is also gradually attaching importance to environmental protection. For Art Sign solar mounting system, one of the most efficient and environmental protection material is ZM coated steel.1.What is Zinc-Aluminum-Magnesium alloy-Coated Steel sheet (ZM coated steel)?
Hot-dip Zinc-Aluminum-Magnesium alloy Coated Steel sheet is a highly corrosion-resistant coated steel sheets with a coating composition consisting of Zinc as the main substrate in combination with Aluminum (11%), Magnesium (3%) and a trace amount of Silicon.
Hot-dip Zinc-Aluminum-Magnesium alloy Coated Steel sheet had been developed successfully in foreign steel mill of Japan (“ZAM brand”), European (ZM Ecoprotect, Magizinc), Australia (ZINCALUME) etc.
ZM coated steel is usually used for Art Sign C type steel solar panel roof and ground mounting system brackets.
2.Features and Mechanical Property of ZM coated steel for C type steel solar mounting system.
ZM coated steel offer several advantages on Art Sign solar mounting system brackets that make them a popular choice for solar installer and building owners alike:
| Anti-corrosion | Self-healing | Long life time | Easy Processing |
| Anti-corrosion property is 10-20 times better than galvanized steel materials. | Zn (OH)2, ZnCl2 and Mg (OH)2 form protective film and restrain cutting places corroded. | Normally, lifetime not less than 30 years. | Perfect property in stretching, bending, welding or other process. |
ZM coated steel mechanical property show as below:
| Grade | C % | Si % | Mn % | P % | S % | Yield StrengthRel. Mpa | Tensile Strength Rm.Mpa | Elongation |
| SCS440 | 0.06 | 0.02 | 0.69~0.72 | 0.009~0.014 | 0.004~0.005 | 335 Mpa | 440 Mpa | 17% |
| S350GD+ZMA | 0.1904 | 0.02498 | 0.61 | 0.009 | 0.0026 | 350 Mpa | 420 Mpa | 22~24% |
