DX51D galvanized coil is a European standard galvanized coil. It is characterized by a zinc layer of 80 grams, a hot-dip galvanized substrate, and a stamping grade of 51. This is the most common specification. "D" represents galvanized sheet, "X" represents the base plate is hot rolled, "51": serial number, no specific meaning, represents general use. A dense layer of pure zinc is attached to its surface, which has good anti-rust effect. Common grades of galvanized coils are SGCC, which is the Japanese standard (Japanese standard).

"Z" means that the product structure is a dense layer of pure zinc on the galvanized iron base material. The surface of this kind of galvanized coil has a fingerprint-resistant coating; -A refers to the A-level surface; C means coil, usually 1.0*1250*C (thickness, width, length). Generally, the coils are random and not fixed. of.
