The Strength and Versatility of Steel Grating - Peterson Co

In construction, it is imperative to have a material that is both strong and durable yet versatile enough to be used in a variety of applications. This is why steel grating remains a property choice in the industry and many others. The material also provides adequate drainage, improving safety and functionality wherever it is used.

View Details

Steel grating, also called bar grating and metal bar grating, has a pattern of crossbars and load-bearing bars created by cutting and opening a flat steel panel. It is lightweight because 80 percent of its area is open space. However, even with these open spaces, thanks to their forge-welded construction, they can withstand loads as heavy as full trucks without separating or severe bending. It also requires minimum maintenance and is corrosion-resistant when made from steel.

Industrial factories, plants, and refineries prefer steel bar grating due to its load-bearing properties and because the open grid allows for easy ventilation and drainage. These two factors make it perfect for flooring in areas where liquids and debris may accumulate and cause potential safety issues. Maintaining sanitary standards in the gas and oil industries is easy when using metal gating for platforms, ramps, catwalks, trench covers, and mezzanine floors.

Workers are able to remain safe in hazardous areas using elevated walkways made of metal bar grating because the grid pattern allows them to maintain visibility no matter where they are in the facility. It is also used in the ramps and loading docks for the logistic centers and warehouses for shipyards and oil fields.

Bar grating also has aesthetic and practical purposes in public and commercial environments. Because it can be made to fit almost any shape, steel grating opens up possibilities for architects looking for ways to improve the functionality of their designs without decreasing the overall visual appeal. For instance, when used as a sunshade, the open grid pattern blocks direct sunlight, reducing the heat while allowing airflow. Steel grating has also been used for cladding and decorative exterior panels.

Other commercial industries and public spaces, such as stormwater management systems and public parking garages, use bar grating for ventilation and drainage properties.

The strength, durability, and versatility of steel grating make it a popular choice for a wide range of applications across industrial and commercial industries and in public spaces. Its open grid design provides excellent drainage and ventilation, and the material can be customized to meet the needs of any project.

Bearing bar types - Steel Grating System

Bearing bar types

Steel grating is made up of bearing bar and cross bar as certain distance by welding or pressure locked. Bearing bar have the types: flat type (also called plain type), serrated type, I bar type (I plain type and I serrated type). According to the bearing bar materials, there are carbon steel bars, mild carbon steel bars, stainless steel bars and so on.

Flat type bearing bars are made from steel strip or slit sheet or from rolled steel. These are produced using high quality steel materials which exhibit good hardness, ductility and tensile strength. Our bearing bars provide extremely good level support for floor joists. They have excellent finishing and based on clients' need we provide them with untreated, galvanized or painted bearing bars.

Applications: flat type bearing bar gratings are the most widely used gratings, available for flooring sidewalk, all kinds of ditch cover, stair tread, etc.

Serrated type-bearing bars delivers excellent performance in application areas, which are slippery, oily, moisture filled. They form a sort of anti-slip grating with their non-slip notches offering them a very good grip. They are made using mild carbon steel or stainless steel materials. We offer variety of serrated products in this category such as, normal serrated, serrated interrupted, serrated trapezoid, serrated carrier bar and serrated carrier bar with cross bar. For inclined gangways with a pitch of 10-25 degrees, we also provide grating with tread strips.

Advantages: Serrated type bearing bar gratings are best non-skid property & safety compared with plain grating.

I type bearing bar is one among the highly demanded product in our range. Features such as high strength, cost-efficient production processes and ease of installation are incorporated in all of our mild steel grating products. Because of its high strength and durability, these bar gratings can withstand extreme loads, quite comparable to solid floorings. Our products have wide range of applications such as Walkways, Platforms, Safety barriers, Drainage covers and Ventilation grates. Standard panels available for this product are in 6 × 1 meter at any size of bearing bar/cross bar and at any center distance as per load design.

Features: I type bearing bar is lighter, not substantially weaken the case of load capacity more economical and practical comparing with plain grating.
