DX51D galvanized steel sheet
DX51D galvanized steel sheet is a type of galvanized steel sheet based on low carbon steel. Its chemical composition mainly includes carbon (C), manganese (Mn), phosphorus (P), sulfur (S), and silicon (Si), with specific contents as follows: carbon content not exceeding 0.07%, manganese content not exceeding 0.50%, phosphorus content not exceeding 0.025%, sulfur content not exceeding 0.025%, and silicon content not exceeding 0.03%.
physical and mechanical properties
The mechanical properties of DX51D galvanized sheet include:
Yield strength: typically between 270-500 N/mm ²
Tensile strength: generally greater than or equal to 290 N/mm ²
Elongation rate: not less than 26%
Manufacturing process and application
DX51D galvanized sheet is manufactured through hot-dip galvanizing process, with a layer of zinc coating on its surface. This process can effectively prevent corrosion of the steel plate surface and extend its service life. Common thickness specifications range from 0.4mm to 3.20mm, with common thicknesses including 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, etc. The width is generally between 600mm and 1250mm, and the length can be customized according to needs, with common lengths ranging from 1m to 12m.
The 275g/M2 Zinc-aluminum-magnesium alloy plating plate produced by GNEE STEEL can be guaranteed not to appear red rust in 30 years under normal processing and use conditions. According to the characteristics of Zinc-aluminum-magnesium, it can completely replace hot dip galvanized products and the use of part of stainless steel.
Application: automatic breeding equipment, fan, photovoltaic bracket, pipe gallery bracket, thin-walled light steel structure chicken house, pig house, electrical cabinet, etc.
