Overview
Steel Bar Grating
Steel Bar Grating, also known as Welded Steel Bar Grate is extremely strong and durable for all load bearing applications and is primarily used for pedestrian and light vehicle traffic. Steel Bar Grating is available in a variety of bearing bar spacing and thicknesses depending on applications and load requirements.
Metal bar grating is the workhorse of the industrial flooring market and has served industry for decades. Strong and durable with an exceptional strength-to-weight ratio, metal bar grating can be easily fabricated to nearly any configuration. The high percentage of open area makes bar grating practically maintenance-free, and all products are fully recyclable.

Welded Grating
Economical design ideal for most industrial applications. Manufactured by welding the bearing and cross bar intersection, typically with automated forge welding equipment. Available in carbon and stainless steel. |
|
|
Swage Locked Grating
Popular for the manufacture of aluminum, stainless steel, and close mesh gratings. Cross bars are inserted into pre-punched holes in the bearing bars and hydraulically deformed to lock the bars in place. |
|
|
Dovetail Pressure Locked Grating
Assembled by inserting pre-punched bearing and cross bars into an "eggcrate" configuration and deforming the cross bars under intense hydraulic pressure. Available in all materials and ideal for architectural and ornamental applications. |
|
|
Riveted Grating
Exceptionally durable grating manufactured by riveting bearing bars and bent connecting bars at their contact points. Excellent for applications involving impact loads and repetitive traffic patterns. |
|
For nearly a century, metal bar grating has been the predominant choice for open metal flooring. Features that make bar grating the preferred product include:
• Available in steel, aluminum, or stainless steel
• High strength-to-weight ratio
• High percentage of open area
• Easily fabricated to any configuration
• Essentially maintenance-free
Steel Bar Grating Surface Options
|
|
|
|
Plain Surface Standard surface with excellent "self-cleaning" characteristics. Suitable for most applications. |
Serrated Surface Preferred for applications where moisture or fluids cause the walking surface to become wet and slippery. |
OnGrip Surface Durable slip-resistant walking surface provides enhanced slip-resistance for applications in the public way. |
Steel Bar Grating Finishes
• Steel products are commonly provided with one of three finishes: bare steel (no finish); painted with one coat of manufacturers red, black, or silver paint; or hot dip galvanized in accordance with ASTM A123.
• Aluminum products are offered mill finish with optional chemical cleaning or anodizing also available.
• Stainless Steel products typically require secondary cleaning due to discoloration that occurs during welding and fabrication. Commercial cleaning, passivation, or abrasive blasting can provide a uniform matte surface while electro-polishing leaves a bright stainless finish.
All products can be provided with specialty finishes including enamel or epoxy paints, or powder coating. When considering specialty finishes, contact US for consultation.

| Painted Steel Bar Grating Standard colors: black, red, or silver or any others. | Anodized Aluminum Grating: clear or bronze. |

The open ends of the grating may be banded to provide additional transverse stiffness and a finished architectural appearance. Achieved by welding a flat bar, similar in size to the bearing bars, to the cut ends, banding enhances safety and should always be specified when gratings are designed to be removable.
Banding can reduce impact stress by transferring load to adjacent bearing bars and should always be specified when gratings are subject to vehicular loads. |
