Surface Treatment of Steel Grating
We offer a comprehensive range of surface treatment options to enhance the durability, corrosion resistance, and appearance of our steel grating, ensuring it meets specific environmental and application requirements.
Hot-Dip Galvanizing (Recommended): This is the most common and robust solution. The grating is immersed in a bath of molten zinc, creating a thick, bonded coating that provides superior corrosion resistance for long-term outdoor and industrial use.
Electro-Galvanizing (Cold Galvanizing): A zinc coating is applied via an electrical current. This process creates a thinner, smoother layer suitable for indoor applications or mildly corrosive environments where a bright, clean finish is desired.
Zinc Plating (Electroplating): Similar to electro-galvanizing, this offers a precise and uniform coating thickness with a bright appearance, often used for aesthetic purposes or specific engineering specs.
Painting / Powder Coating: Ideal for applications requiring specific color matching for safety or aesthetic reasons. We offer a variety of paint systems and powder coatings for enhanced visual appeal and moderate protection.
Anti-Rust Oil Immersion: A temporary protective solution that prevents oxidation during storage or transportation. It is not recommended for permanent outdoor exposure.
Plastic Coating / Dip Coating: The grating is coated in a layer of PVC or other polymers, providing excellent chemical resistance, electrical insulation, and a comfortable grip, making it perfect for handrails and specialized fixtures.
Mill Finish (No Treatment): The raw, untreated steel surface straight from production. This is a cost-effective option for indoor, dry environments where corrosion is not a concern, leaving the final treatment to the end-user.
