Imagine walking along an ocean boardwalk, watching the waves crash along the shore. You see a bird dive into the ocean as the water swells towards you. The large wave crashes against the boardwalk, and you look down. The serrated steel grating of the walk kept your feet nice and dry. How?

So, you want to know how these metal grates work, their benefits, and when you should use them for your at-home projects? Keep reading to deep dive into the process.

What Are Serrated Type-Bearing Bars?

The metal serrated type-bearing bars make up the load area of the welded grating. Most bars are either welded or riveted together, depending on the client’s needs, wants, and specifications.

Serrated type-bearing bars are made from low carbon steel, aluminum, or stainless steel. The types of grating include serrated welded steel with either a semi-circular surface, a trapezoidal surface, or an intermittent surface. Pattern-wise, the materials come in a normal, interrupted, carrier bar, or carrier bar with crossbar shapes. Some grates come with tread strips.

Uses of Steel Grating

Among the types of grating, serrated steel grating is used for a variety of walkways and platforms. Some apartment complexes choose to use serrated welded grating to create walkways along their units; engineers also create balconies using the same material.

For public construction projects, steel grating is used to create pedestrian cross-overs over highways and overpasses. Factories utilize the metal to create a safer working environment for their employees.

To create more grip and traction in environments filled with water, oil, and other natural elements, the best grating is used on stairs. Public beaches, parks, and other natural areas commonly have serrated steel grating stairs and walkways. In keeping the ground dry, workers install grating as drainage trench cover. The material gives overflowing water a convenient place to go.

Kinds of Serrated Steel Grating

Before diving into serrated steel grating, let’s dive into the different types available. These platforms are made of aluminum, stainless steel, or low carbon steel.

You can choose the welded serrated steel grates. First, the pieces of metal are welded together. You can choose between flux-cored arc, stick-shielded-metal arc, gas metal arc, laser beam, electron-beam, plasma arc, gas tungsten arc, atomic hydrogen, and electroslag welding. If you don’t want welded-together grates, you can choose between three other options: swage-locked, press-locked, and riveted grates.

Let’s go over a few of the differences between the various types of materials used in serrated steel grating, as well as the benefits and drawbacks of each.

Aluminum Bar Grating

Aluminum is not only lightweight, but it is also incredibly durable. This makes it a very versatile material with a wide variety of applications. Aluminum bar gratings can be used for both industrial and architectural purposes.

Carbon Steel Grating

Carbon steel is an incredibly strong material, meaning that it can hold up in various applications and is highly durable. That said, carbon is highly susceptible to corrosion, meaning it is not a good choice for any materials that are highly corrosive or are kept in corrosive environments.

Benefits of Serrated Welded Grating

Builders choose serrated welded grated due to the special features that come with the material. With the raised surface of the metal grates, the slip resistance performance is excellent. In wet and slippery places, the grooves and edges of the material give people footholds. With most types of grating, a galvanized surface treatment is included. The treatment allows for amazing corrosion resistance performance. Because of this, serrated steel grating products come with a long product service life.

If you need a walkway or ramp in an environment that’s either salty or corrosive due to to other chemicals, consider steel grating. The metal has high-quality chemical stability, meaning that corrosion won’t affect your projects as much. For public works projects, using steel grating gives both you and the public peace of mind. The serrated surface gives pedestrians traction and helps prevent them from slipping. Plus, weather debris does not collect on the platforms due to the gaps in each grate.

Partnering With a Professional

If you’re interested in using the serrated steel grating but don’t know how to get started, consider partnering with a professional team. Along with helping you determine the best metal grate for your project, a company like Bushwick Metals can also assist in steel saw cutting, shearing, stamping, and slitting metal.

Expanded Metal Options

Do you need a solid metal surface for your construction project? Expanded metal options include standard/regular, flattened, architectural/decorative meshes, and grating. You can choose between carbon, galvanized, or stainless steel, or aluminum. If you need expanded metal in other shapes and sizes, Bushwick Metals has what you need. Those looking specifically for grating should keep reading, to figure out which kind works best for them.

Grating Options

The engineers utilize an automatic weld-forge methodology to craft the types of grating. The machine joins the bearing bars directly to the cross bars in a form of one-piece constructed machine. For color options, you can choose between black-painted, galvanized, mill, or bare finish.


This is a grating product that locks through pressure. The spacing is closed bars to allow for ease of motion for pedestrians. The option also complies with the ADA (American’s with Disabilities Act).

Grip-Strut Safety

A one-piece diamond-shaped grate made from lightweight metal, the product is made with complete slip resistance in mind for workers dealing with rough weather.

Grate-Lock™ Interlocking-Type Mezzanine

This is a system made of interlocking planks, treads, and other parts. The rung design allows for ease of motion on all terrains. Plus, you can use lighter-gauge steel as the building material for appropriate building projects.

Heavy-Duty Grip Strut

This is a plank grating system that allows for a 24-foot clear span if so desired. The material allows you to support heavier loads for longer periods of time. If you own a large corporation with many factories, consider this option to improve the experience of your employees.

Common Materials in Serrated Steel Gratings

  • Low carbon steel is easy to mold and weld and is an economical choice. It is often used in commercial or industrial settings.
  • Stainless steel is useful in corrosive environments, such as those where it may encounter chemicals or food.
  • Aluminum is lightweight and nonmagnetic, and is often used in a commercial setting on ships or in waste treatment.

The material you choose will depend on the specifics of your project. Experts at Bushwick Metal can help you determine what the best material is for your use.

Ways to Produce Serrated Steel Gratings

Swage-locked grates are very strong and weight less than other options. Instead of being welded together, they are pinched by machinery. Hydraulic pressure is used to make press-locked grates, which are just as strong as welded grates. The hydraulic pressure permanently locks the bars in place and gives a smooth finish. Cold press riveting is the oldest type of grates, and produces grates that are both stiff and strong.

Both welded and non-welded serrated steel gratings are very strong. These grates don’t bend and can carry large amounts of weight. They are easy to install, and if you later need to change the area, they can be removed just as easily. When compared to flat surfaces, even smooth steel gratings, serrated gratings make workers or pedestrians safer. Even in rain or high winds the serration provides a foothold for shoes, and serrated steel grating is sometimes known as anti-slip grating.

Standards For Steel Gratings

Manufacturers commonly use standards set by the American National Standards Institute (ANSI) when creating their products. ANSI five classifications focus on the type of work that the grating will perform and the weight it can hold.

  • Light Duty grates are meant for pedestrians, and can hold up to 2,000 lbs. This classification is not intended to be used by vehicles.
  • Medium Duty grates are used for light traffic, such as in a parking lot in a residential area or on sidewalks, where there is very little traffic. They are used to support between 2,000 lbs. and 5,000 lbs.
  • Heavy Duty grates are for commercial vehicles, such as tractor trailers or box trucks. This type can support between 5,000 lbs. and 7,500 lbs. of weight.
  • Extra Heavy Duty grates are often used for bridges and highways, and they can carry up to 10,000 lbs.
  • Special Duty grates are the highest class, and are used to handle over 10,000 lbs. of weight. They are often used in airports.

Serrated steel gratings are used for a wide variety of applications, so it makes sense that there are various classifications of them, ranging from small light-duty grates to enormous special-duty grates used in airports. These classifications make it significantly easier to decide which type of grate you need to use for your project.

Even knowing the ANSI classifications, though, you might have some questions about which grating to choose or which one best applies to your project. Our team of experts at Bushwick Metal can take a look at your project and help you determine which grates are most appropriate for your needs.
