What Is DX51D galvanized steel?
DX51D galvanized steel is a low-carbon cold-rolled steel substrate that undergoes a hot-dip galvanization process. This treatment gives the steel excellent corrosion resistance, making it well-suited for environments exposed to moisture and harsh weather conditions. Known for its outstanding durability and formability, DX51D is widely used in industries such as construction, automotive, and home appliances, where long-lasting performance is essential.
Hot-dip galvanized steel is a type of steel coated with zinc through a hot-dip process to provide enhanced corrosion resistance. GNEE STEEL Group DX51D hot-dip galvanized steel is supplied in hot-rolled and cold-rolled states. Its zinc coating weight typically ranges from Z60 to Z275 g/m².
DX51D is a cold forming steel grade under EN 10346.
1.0917 is its official steel number used in European steel classification systems.
