Anping Xinye Metal Wire Mesh Products Co., Ltd, based in Hengshui, Hebei, China, is a professional manufacturer of metal gratings. Our Hot Dipped Galvanized Flat Bar Steel Grating is engineered for heavy-duty flooring and trench covers, offering exceptional strength, corrosion resistance, and long service life. This product is designed to meet the rigorous demands of industrial environments, providing a reliable walking surface and secure cover for drainage channels, pits, and trenches.
Manufactured from high-quality steel flat bars, each panel undergoes a hot-dipped galvanizing process that delivers a thick, uniform zinc coating. This ensures superior protection against rust and harsh weather conditions, making it ideal for both indoor and outdoor applications. The open grid design allows for efficient drainage, light transmission, and ventilation, while the robust construction supports heavy loads, including forklifts and heavy machinery.
