One of the primary materials used in the production of metal bar grating is steel. Steel grating is preferred for its strength and resilience, making it suitable for applications that demand high load-bearing capacity. Galvanized steel, for instance, is treated with a protective coating that enhances its rust resistance, ensuring a longer lifespan even in the most corrosive environments. Stainless steel grating, on the other hand, offers superior corrosion resistance and is often utilized in food processing, pharmaceutical, and marine applications where hygiene is paramount.
