Product Introduction

Pre-painted Galvalume Steel Sheet is a high-performance coated steel product manufactured by applying a layer of aluminum-zinc alloy coating to a steel substrate, followed by a durable paint coating process. The base material usually consists of cold-rolled steel with a Galvalume coating containing approximately 55% aluminum, 43.4% zinc, and 1.6% silicon, which provides excellent corrosion resistance, heat resistance, and long-term durability. The surface is coated with advanced paint systems such as PE, SMP, HDP, and PVDF, offering excellent color retention, weather resistance, and surface protection under different environmental conditions.

Our Pre-painted Galvalume Steel Sheet is supplied with customizable specifications, including thickness from 0.12mm to 2.0mm, width from 600mm to 1500mm, and various surface finishes such as smooth, embossed, and patterned designs. The product features strong adhesion, good formability, lightweight structure, and outstanding resistance against rust, UV radiation, and high temperatures. It is widely used in roofing sheets, wall panels, steel structures, home appliances, automotive components, and industrial buildings. With strict quality control, SGS inspection support, and international standard compliance, our pre-painted Galvalume steel sheets provide reliable performance and a cost-effective solution for global construction and manufacturing applications.
