Mild steel
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.
When purchasing DX51D galvanized sheet, the choice between hot-dip
galvanizing and cold dip galvanizing is also important. Hot dip
galvanizing is a chemical reaction, while cold dip galvanizing is a
physical reaction. Hot dip galvanizing has a better anti-corrosion
effect.
The 275g/M2 Zinc-aluminum-magnesium alloy plating plate produced by
our factory 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
