How is heavy-duty steel grating manufactured?
Heavy-duty steel grating can be integrated into an extensive range of industrial projects, from airplane hangars to drainage grates. Contractors rely on steel grating products for roadway inlet gratings and other industrial applications. With its high demand in industrial construction, steel grating needs to be made as quickly and efficiently as possible. Laurel Custom Grating (LCG) is at the forefront of automated steel grating manufacturing. The company’s modernized fabrication process ensures their products are of the highest quality—and that they arrive on time. Bill Adams, sales team lead at LCG, recently discussed how LCG combines hand-welding and automated technology to produce versatile, durable steel grating products.

Hand-welded, heavy-duty steel grating offers design versatility and a quick manufacturing process, so the products can make their way to construction sites faster. Our 30,000-square-foot manufacturing facility at LCG features large capacity hydraulic presses with automated feed lines and high-production robotics. By using robotic technology, we maintain our competitive edge in the steel grating market. Our high-capacity hydraulic presses are precise and economical, providing users with reliable, heavy-duty steel grating products at an affordable price.



Automation allows us to maximize productivity and efficiency. Our robotic welder can weld commercial steel grates from start to finish. This means less time needed for staging materials—and less people needed for the job. Instead of having to do the fitting process and the welding process in two different areas, the robotic welder puts all of the material into the fixture and then it welds it on the spot.

This hand-welding process is very efficient and allows for customization, too. First off, LCG’s team cuts the steel to size, and then punches in the bearing bars to allow the cross bars to fit in. Then they fit the steel grating to spec and assemble it. The welders complete all of the final touch-ups to ensure the gratings are in compliance with National Association of Architectural Metal Manufacturers’ standards, and the customer’s specific requirements. Our manufacturing facility in Everson, Pennsylvania, also offers convenient access to major interstates, which makes the shipping process even simpler and more energy-efficient.

How to Avoid Problems When Installing Stair Treads
When using resilient stair treads on angled “ADA” steps, choose a tread that is notched so it can bend (top) or an angled nose tread (bottom) that will fit snugly against the step.

The use of epoxy nose filler can prevent cracking of stair treads.
Stair treads have been around for a long time, and are a tough, durable and safe covering for stairs from heavy duty to light usage. Growing up in the industry, I always found stair treads an interesting material. I spent several years working for a major manufacturer of stair treads, and recently started working with another. You could say this is a product category that is near and dear to my heart. I recently visited an office where diamond design rubber stair treads were installed and asked how old they were. The answer, “1965,” did not surprise me. Done properly, stair treads will last a good long time.

This rubber stair tread was properly trimmed to butt up to 1/8” VCT in the corridor at the top of the stairs. This is also a nice use of stair treads with carpet as the riser material.
The keys to stair tread installation success start before even taking the order. There are two types (rubber and vinyl), two shapes (round nose or square nose), two different constructions (one piece tread and riser or separate tread and riser), and a variety of surface textures (diamond, ribbed, circular, smooth, etc.). Rubber treads are the most widely used, for everything from the most heavy traffic area to light duty use. Vinyl treads tend to be for light duty use.

As for the type of nose, this is an important detail. “Square Nose” could be a 90-degree angle step or in the case of newer steps the riser is angled back to provide a more safe walking surface, as per the Americans with Disabilities Act (ADA). Make sure the tread can be angled. Some treads come out of the box already angled and some have a notch at the nose so it can be bent slightly, as shown in the photo below. I remember being on a job where square nose treads were ordered for an angled step. I had to show the installers how to grove out the back of the nosing by hand. We made it work and it turned out to be a beautiful job, but the extra time required could have been avoided by ordering a tread that was able to handle an angled riser.

Round nose treads also need some careful attention. Not all treads are able to wrap all the way around a typical round nose wooden step, so take an actual sample to the job to be sure.

Open trenches, broken pits and displaced manhole covers are all potential dangerous trip and fall hazards.

For instance, in public places including on footpaths and nature strips, there are many utility pits and manholes that have been installed by telecoms, power, water and other utility companies.

At times, due to ongoing civil works, repairs, upgrades or general works, pit covers need to be replaced. If left in state of disrepair or if the works are ongoing, these open pits/holes can be a serious hazard.

In addition, pit covers which are located near or on footpaths, may develop exposed or raised edges, creating additional trip hazards.

Therefore, it is extremely important to cover trenches, damaged pits, raised pit covers and damaged manhole covers with a sturdy, durable and non-slip cover.

The WB Safety trench cover has been designed to cover these dangerous trip and fall hazards and can be used as a trench cover, pit cover, footway board etc. The cover can be a temporary or semi-permanent installation.

The safety trench cover is available in 2 sizes:

1200mm x 800mm – suitable for pits/trenches up to 700mm wide

1600mm x 1200mm – suitable for pits/trenches up to 900mm wide

These versatile safety covers are exceptionally rigid in construction, yet lightweight. The sturdy glass-reinforced composite trench cover maintains performance in the most demanding situations.

Designed primarily for use in street works or construction, the safety covers are made from a single piece of glass-reinforced composite and can support a distributed weight of up to two tonnes.

Therefore, potential trip and fall hazards on the street, footpath and construction site can all be reduced or eliminated with the WB safety trench cover.

Correct Grating of Production Method, Materials, Mesh Size and Surface
Steel gratings are widely used in many industrial applications including factory platforms, walkways, stair treads, trench covers, fences, ceilings, etc. It ensures personnel safety and provides high strength, great carrying capacity and excellent corrosion resistance. We have stainless steel gratings, galvanized steel gratings, pressure-locked steel gratings and heavy steel gratings for you to choose from. Then how to choose the right steel gratings? Here are some tips on how to choose the correct steel gratings for your reference:

Welded steel grating or press-locked grating

The main difference between the two gratings is the mode of production.

Welded steel gratingIt is a steel grating fixed by pressure resistance welding in the each intersection point of bearing bar and cross bar, and the cross bar is generally used by square steel or twisted steel. It provides a robust structure, high strength and great carrying capacity. It is commonly served as walkways, stair treads, fences, floors, etc.

Press-locked grating
It is a steel grating fixed through the pressure to make the cross bar into the pre-open flat steel in the each intersection point of bearing bar and cross bar, and the cross bar is usually flat steel. It offers a stable connection and an attractive appearance. It is widely used in factories, civil and commercial buildings for stair treads, trench covers, floors, platforms, fences, etc.

Materials

When you choosing materials, you must consider the expected use of the grating. Is it used only for grating walkways? Or a shelf? Does the vehicles need to pass through the gating? In these cases, you must ensure that the grating has adequate strength to ensure the correct choice of materials.

Each material has its unique characteristics and applications. Here we’d like to introduce it briefly to help you choose the right material.

Which mesh size to choose

The common mesh size of welded steel gratings is 33 mm × 33 mm and 34 mm × 38 mm. According to the different load, place, use, method of application and the requirements of customer, there are different ways to divide grating mesh.

• Load: The smaller the mesh, the higher the load capacity of grating.
  
  
• Application: Larger mesh allows more light to pass through. Smaller mesh prevents objects from falling off.
  
  
• Customer: The shape and size of the mesh determines the optical perception of the grating.
