G550 High Gloss Brick Pattern Pre Painted Steel Coil for Roofing Wall Panels and Decorative Building Applications

１．Product Overview

G550 High Gloss Brick Pattern Pre Painted Steel Coil is a decorative color coated steel product designed for roofing panels, wall cladding, building decoration, and industrial fabrication. The high-gloss brick pattern surface combines the strength of galvanized steel with an architectural appearance that simulates traditional brick finishes while maintaining the lightweight advantages of steel.

The product is manufactured using galvanized steel substrates and continuous coil coating technology, providing both corrosion resistance and decorative performance for indoor and outdoor applications.

２．Technical Solution

The steel substrate is protected by a zinc coating ranging from 30–275g/m², which provides corrosion protection in construction and industrial environments.

The decorative brick pattern finish is produced through a continuous coating process that combines primer and color coatings to achieve a high-gloss textured appearance. Surface treatment options such as passivation, chromating, skin-passing, and anti-fingerprint treatment can be selected according to processing and service requirements.

Multiple steel grades from commercial quality to high-strength G550 grade are available to support different forming and structural applications.
