Steel grating, also known as steel grid or bar grating, is a versatile and robust flooring solution designed for industrial, commercial, and architectural applications. Made from high-quality carbon or stainless steel, our steel grating features a lightweight yet durable design that ensures excellent load-bearing capacity and long-lasting performance.
Key features include a slip-resistant surface, customizable sizes, and various spacing options to suit different needs. The open design allows for optimal drainage and air circulation, making it ideal for demanding environments such as factories, walkways, and drainage covers.
Whether you require heavy-duty steel grating for energy sectors or lightweight options for pedestrian areas, our products meet safety standards while facilitating easy installation and maintenance. Enhance your project with our top-quality steel grating to achieve maximum efficiency and safety.
Steel Grating Types
Welded Bar Grating - Plain (Flat)
One of the most widely used grating types due to its versatility, durability, and cost-effectiveness. Typically made from carbon steel or stainless steel, it features a smooth, flat surface ideal for applications requiring load-bearing strength and stability.
Plain bar grating is commonly used in industrial flooring, walkways, drainage pit covers, stair treads, platforms, and ventilation grilles. Its open grid design allows for efficient drainage and ventilation, making it suitable for both indoor and outdoor environments. It provides a safe and sturdy walking surface while offering low maintenance and long-term reliability.
Serrated Bar Grating
Serrated steel grating is designed with serrated edges on the bearing bars, which provides enhanced non-slip performance and increased safety compared to plain grating. This makes it an ideal choice for environments where slip resistance is crucial, such as industrial platforms, walkways, stair treads, and areas exposed to wet or oily conditions.
In addition to its excellent anti-slip properties, serrated steel grating is durable, resistant to corrosion when galvanized, and offers high load-bearing capacity, making it suitable for both heavy-duty and light-duty applications.
Press Locked Grating
Also known as pressed or pressure lock grating, is manufactured from low carbon steel, stainless steel, or aluminum. It is made by bonding two precisely slotted bars together under tremendous hydraulic pressure, creating a permanent, secure lock.
Known for its high strength and solid structure, press-lock grating is widely used in industrial plants, commercial buildings, and municipal engineering projects. Common applications include stair treads, platforms, walkways, security screens, tree and trench covers, and drainage covers. For enhanced slip resistance, serrated surfaces are also available.
