DX51D G275 Hot Dipped Galvanized Steel Coil 0.15–3.8mm for Roofing and Industrial Freezers

１．Product Overview

DX51D G275 hot dipped galvanized steel coil is used for roofing sheets, wall panels, explosion-proof steel, electrical control cabinets, industrial freezers, residential buildings, and industrial buildings.

The product is manufactured according to ASTM A653, JIS G3302, and EN10147 standards. Zinc coating from 40g/m² to 450g/m² provides corrosion protection for steel coils used in construction, appliances, transportation, industrial equipment, and furniture manufacturing.

２．Technical Solution

The steel substrate is coated by continuous hot dip galvanizing to form a protective zinc layer on the surface.

Surface treatments include passivated, chromated, oiled, and anti-finger acrylic coating. These treatments support storage protection, handling cleanliness, and downstream fabrication.

Regular, minimized, big, and zero spangle options are available for different appearance and processing requirements.
