Hot Dip Galvanized Grating for Industrial and Structural Use


Hot Dip Galvanized Grating is a versatile and durable steel grating solution. Manufactured by QINGDAO HIGHLIGHT MACHINERY CO., LTD., it is designed for demanding industrial and structural applications. This product combines strength, corrosion resistance, and safety, making it suitable for various environments.


The grating is made from carbon steel, offering excellent load-bearing capacity. Its surface undergoes a hot-dip galvanization process, forming a protective zinc layer. This process enhances its resistance to rust, extending its lifespan in outdoor and harsh conditions.


The grid structure consists of load-bearing flat bars and perpendicular crossbars. These are welded together to ensure stability and uniform strength. It is available in different types, including plain, serrated, and I-beam styles, to meet specific project requirements.


This steel grating is widely used in industrial platforms, stair treads, trench covers, and walkways. Anti-slip serrations can be added for increased safety, especially in slippery areas. Its lightweight design allows for easy installation through welding or bolt connections.


Customizable dimensions and bar spacing are available to suit unique applications. The product's quality and adaptability make it a trusted choice for engineers, builders, and contractors.
