Steel Grating

Steel Grating, also known as metal grating or steel bar grating, is a type of metalwork product made up of steel bars that are either welded or locked together. It forms a grid – like structure, which is widely used in various industries and applications due to its unique properties.

Steel Grating is designed scientifically and equisitely, is very strong and safe to support floors and walkways. It can be used for ceiling, interior and exterior decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.

Our Steel Grating, also known as Bar Grating, is an open grid assembly of bearing bars and cross bars, engineered for maximum strength, safety, and durability across industrial and commercial applications. This product offers superior load-bearing capacity while allowing for excellent passage of light, air, water, and debris, which minimizes maintenance requirements.

Key Features & Advantages:
High Strength-to-Weight Ratio: The forge-welded construction creates a positive, fused connection between bars, providing a robust structure ideal for platforms and walkways without excessive weight.
Superior Corrosion Protection: The standard hot-dipped galvanized finish ensures long-term resistance to rust and weather, making it the top choice for outdoor, marine, or chemical environments.
Enhanced Safety: Available with an optional serrated (anti-slip) surface to provide secure footing even in wet, oily, or icy conditions, complying with OSHA and workplace safety standards.
Self-Cleaning Design: The high open-area design ensures debris, snow, and liquids fall through, keeping the walking surface clean and safe.

Primary Applications:
Industrial Plants & Factory Floors (catwalks, platforms)
Trench & Drain Covers (municipal infrastructure, driveways)
Stair Treads (commercial and industrial staircases)
Bridge Decking & Mezzanines
