PPGI HDG GI SECC DX51 Galvanized Sheet Metal Rolls with Minimized Spangle for Construction

１．Product Overview

PPGI HDG GI SECC DX51 galvanized sheet metal rolls are used for construction, roofing components, outside wall panels, garage doors, window blinds, household appliances, transportation parts, industrial cabinets, refrigeration equipment, and furniture components.

The product is supplied as galvanized sheet coil with regular, minimized, big, or zero spangle surface. Minimized spangle is suitable for applications requiring a cleaner galvanized appearance and stable surface performance for downstream fabrication.

２．Technical Solution

The coil is produced through hot dipped galvanizing, hot rolling, cold rolling, or related coated steel processing.

The galvanized layer provides corrosion protection for construction and industrial applications. Surface treatments such as chromated, dry, oiled, Cr3 treated, and anti-finger acrylic coating support storage protection, handling performance, and later processing.

Cutting and slitting can be arranged according to customer requirements for roofing, profiles, purlins, and other structural uses.
