Types of Serrated Steel Bar Gratings

Welded Serrated Steel Bar Grating

Welded gratings are strong grids made of bearing and cross bars. These steel bearing bars are neither chipped nor pierced. In contrast to press-locked gratings, the welded gratings have stretched and twisted steel cross bars that are welded to the serrated bearing bars in a perpendicular direction. This is to ensure the sturdiness of the serrated steel bar grating.

The opening space can also be reduced to keep things from slipping through.

Welded serrated steel bar gratings are mostly made using low carbon steel or stainless steel. It is surface treated by the processes such as hot-dip galvanizing, mill finishing, and paint or powder coating.

Welded serrated steel doesn’t bend even in the harshest conditions. Due to the inclusion of twisted cross bars, it also provides an anti-slip effect. It is so stable that even in its ungalvanized form, it doesn’t lose its steadiness.

It can be used for platforms, stair treads, shelves, floors, and ceilings of any commercial or residential area.

Apart from the material and surface treatment, the bearing bar height and thickness, along with the mesh size of welded serrated steel bar gratings, can also be altered to meet specific application needs.

Swage-locked grating

Swage-locked Serrated Steel Grating

The swage-locked serrated steel grating can be made up of aluminum or stainless steel. The cross bars are put through already punched perforations in the bearing bars, after which they are hydraulically swaged under lots of pressure to set them securely.

Serrated Swage-locked steel bar gratings are classified into three types: serrated rectangular bars, serrated I bars, and serrated T bars. The most common kind is Serrated I bar swage-locked grating, which is lightweight and less expensive than rectangular bar swage-locked grating.

This type of steel grating can be used in stair treads, floors, platforms and bride decking, etc., in the industrial sector. These gratings can be used as tread gratings, floors, platforms, or decks in the commercial sector.  

It can be the ultimate choice in all these areas due to its anti-corrosive properties, immense strength, rigidity, fast speed, and easy installation.

Press-locked Serrated Steel Grating

The press-locked serrated steel grating can also be called pressure-locked serrated steel grating since it is manufactured by applying tremendous hydraulic pressure. This pressure connects the two close-tolerance slotted bars, firmly securing them in place.

These press-locked serrated steel bars may be hot-dip galvanized and painted or powder coated.

These press-locked serrated steel bars have several advantages, such as their non-slip and anti-corrosive properties. They are also lightweight but extremely sturdy. Their strength is the most common use of stair treads, security screens, and bridges.

They also have a long lifecycle and are also easy to install or remove. Their attractive appearance is an eye-turner, but the best part is that this appearance isn’t easy to deform.

Riveted Serrated Steel Grating

Riveted serrated gratings are heavy-duty steel bar gratings with more load-bearing capacity than press-locked, welded, or swage-locked serrated steel bar gratings with the same span, thickness, and depth of grating.

It comprises bearing bars and crimp bars that are fastened together using rivets.

Riveted gratings are available in a number of materials, including aluminum, carbon steel, and stainless steel.

Riveted gratings are used in various applications, including industrial and commercial settings.

For applications with high corrosion resistance, the serrated carbon steel bar grating is best as it can undergo surface treatments like galvanization or paint to enhance its corrosion resistance further.

Besides, aluminum serrated steel bar grating can also be helpful for applications where good resistance to corrosion along with a lightweight structure is required.

In contrast, stainless steel serrated steel bar grating is most suitable for harsh environments, where extra resistance to acid and alkali is required.

2. Preparing Raw Material:

When the design is complete, our manufacturing team begins sourcing and preparing the highest quality raw materials for the serrated steel bar grating. All primary materials are purchased from reputable suppliers and examined to guarantee they are eco-friendly, durable, and of high quality.

Typically, raw and primary material processing requires 4 to 5 days. Nevertheless, finding personalized and unique materials may take considerably more time.

3. Manufacturing of Steel Grating:

The different types of steel bar gratings, including swage-locked, press-locked, riveted, and welded steel bar grating, are manufactured with slight changes in the procedure.

The slots are first punched on both bearing and cross bars for the press-locked steel bar grating. Then these bars are placed onto each other perpendicularly to form a grid and are fixed together using extra force hydraulic pressure.

For the swage-locked steel bar grating, there are diamond-shaped apertures made on bearing bars (plates) with a machine’s help, irrespective of whether they are the I-bar, rectangular bar, or T-bar. Following that, the crossbar, either round or square-twisted, is put into the pre-punched holes of the bearing bars (plates) to produce a grid-like structure. Machines on the manufacturing line are also used in this procedure. Finally, hydraulic pressure is applied to them to fix their shape in place.

The bearing bars constructed of steel strips are neither notched nor pierced for welded serrated steel bar grating. The drawn and twisted steel cross bars are instead forced into the bearing bars, and resistance is welded at every junction to achieve high stiffness.

For riveted serrated steel bar grating, bearing bars and crimp bars are placed together to achieve the desired design and then joined together using rivets by a hydraulic machine.

The entire manufacturing for all of these serrated steel bar grating types may go on for approximately as low as five days or as high as eight days.

4. Surface Finishing:

Always considering the customer’s opinion, the surface of the manufactured serrated steel bar is coated with either paint or powder. Other ways its surface finishing may be done is through hot dip galvanizing or mill finishing.

About three days are enough for this process to take place.

5. Product Finalizing:

After the serrated steel bar grating is ready, the product is carefully examined for any irregularities or defects. It is checked to see if it fulfills our quality requirements.

Then the grating is packaged and dispatched to our client after approval.


The finishing and packaging process normally takes three days, while shipping might take anywhere from five to forty-five days, depending on the specified address and delivery method.
