What is aluminum grating
Definition and structure
Aluminum grating is a strong and light panel. It is made from flat and square aluminum bars. These bars are shaped by extrusion. The bars are joined together tightly, but not by welding. This makes the grating tough and safe to use. There are two main surface types. One is plain and the other is serrated. Serrated surfaces help stop people from slipping in wet or oily spots.
Here is a table that lists the main features of aluminum grating:
| Feature | Description |
|---|---|
| Material | Flat and square aluminum bars formed by extrusion |
| Connection | No welding points, firm and secure |
| Weight | About one-third the weight of steel per cubic foot |
| Strength | High strength, supports heavy loads |
| Surface Types | Plain and serrated (for anti-slip) |
| Surface Treatment | Mill finish, anodizing, or powder coating |
| Corrosion | Self-repairing oxide layer for protection |
The oxide layer on aluminum grating is very important. This layer sticks to the metal and keeps out water and air. It also blocks things that cause rust. If the surface gets scratched, the oxide layer comes back fast. This helps the grating stay strong and look nice for a long time.
Aluminum grating is also special because it is non-toxic. It does not let bacteria grow easily. You can use it in places where you need things to be clean, like food factories or hospitals.
Common uses
You see aluminum grating in many places. It is strong, light, and does not rust. Here are some common ways people use it:
- Walkways and platforms in factories
- Drain covers in cities and factories
- Fences and guardrails for safety
- Decoration for building walls outside
- Pavements and ramps in public places
Aluminum grating is good for floors that must hold weight. For example, types like 11-SG-4 or 11-SGI-2 can hold up to 100 pounds per square foot. They do not bend much. This makes them great for places where people walk or work.
When you look at other materials, you see some differences. Aluminum grating is heavier than fiberglass grating. But it is much lighter than steel grating. Steel grating can be 75% heavier than fiberglass. Aluminum is in the middle. This mix of weight and strength makes it easy to install and move.
Tip: If you want a floor or cover that is easy to move, does not rust, and stays clean, aluminum grating is a smart pick.
Types of aluminum grating
There are different types of aluminum grating you can pick. Each type has its own shape and works best in certain places. The table below shows how the types are not the same:
| Feature | Swaged Grating | I-Bar Grating | Press-Locked Grating |
|---|---|---|---|
| Material | Aluminum alloy, carbon steel | Aluminum alloy, carbon steel | Aluminum alloy, carbon steel |
| Weight | Lightweight (1/3 of galvanized steel) | Moderate weight | Varies |
| Strength | High strength and rigidity | Comparable strength | Varies |
| Corrosion Resistance | Yes | Yes | Yes |
| Surface Type | Plain or serrated | Plain or serrated | Plain or serrated |
| Applications | Walkways, platforms, security screens | Industrial applications | Varies |
Swaged grating
Swaged grating is used a lot in factories. It is made by a process called swaging. Machines push cross bars into bearing bars. There is no welding. This makes the grating both strong and light. Swaged grating is good for walkways, platforms, and stairs. You see it in chemical plants and food factories because it does not rust much.
I-bar grating
I-bar grating has bars shaped like the letter “I”. These bars are strong but use less metal. This makes the grating lighter than other types with the same strength. You use I-bar grating when you want to save weight but need a strong floor. Many factories and work sites use this type for heavy walkways and platforms.
Press-locked grating
Press-locked grating uses flat bars pressed together very hard. Machines push the bars into slots so they lock tight. There is no welding. This type looks smooth and nice. You see press-locked grating in buildings for sunshades, grills, and fences. Architects like it because it looks good and works well.
Typical applications
Aluminum grating can be used in many places. Here are some common ways to use each type:
- Swaged grating: walkways, platforms, stairs, fencing
- I-bar grating: factory floors, heavy platforms, ramps
- Press-locked grating: sunshades, grills, soffits, fencing, panels
Tip: Pick the type that matches your project. Swaged grating is best for strength and light weight. I-bar grating is good when you want to save weight. Press-locked grating gives a neat look for buildings.
Manufacturing of aluminum grating
Swaging process
The swaging process is used a lot to make aluminum grating. Machines push cross bars into bearing bars very hard. The bars lock together and stay tight. Welding is not needed for this process. Swaging makes the grating strong and safe to use. You can use swaged grating for walkways, stairs, and platforms. This method keeps the grating light, so it is easy to move and install.
Extrusion and assembly
Extrusion shapes aluminum bars before they are put together. Hot aluminum is pushed through a mold to make flat or I-shaped bars. This gives bars smooth surfaces and exact sizes. Extrusion also makes the grating stronger and helps it last longer. Here are some good things about extrusion:
- The process makes complex shapes with little waste.
- Impact extrusion makes the metal stronger by forming fine grains.
- The grating lasts longer and holds more weight.
After extrusion, workers or machines put the bars together to make panels. They use swaging or press-locking to join the bars. The finished product is strong and light.
Quality standards
When you buy aluminum grating, you want it to meet high standards. Makers follow strict rules to make sure the grating is safe and works well. Here is a table of common quality standards:
| Standard | Description |
|---|---|
| ASTM B209/B209M | Standard for Aluminum and Aluminum Alloy Sheet and Plate |
| GB/T 3880.1-2023 | Delivery rules for Wrought Aluminium and Aluminium Alloy |
| GB/T 3880.2-2012 | Mechanical Properties for Wrought Aluminium and Aluminium Alloy |

Benefits of aluminum grating
Corrosion resistance
Aluminum grating lasts a long time in hard places. The metal makes a layer that fixes itself. This layer keeps water and air away from the surface. If you scratch it, the layer comes back fast. In places near the sea, aluminum grating does not rust like galvanized steel. Galvanized steel rusts when its coating is gone. Aluminum stays strong and looks good. You can use it by the ocean or in wet factories without worry.
Strength-to-weight ratio
Aluminum grating gives you a strong floor that is not heavy. It has a great strength-to-weight ratio. You can move and put it in place easily. It still holds a lot of weight. Many companies use it for walkways, ramps, and platforms. The panels are light, so you save time and work when installing them. Your building does not have to hold as much weight.
- Aluminum bar grating is strong for how light it is.
- You can use it where steel would be too heavy.
Non-sparking and durability
Safety is very important in places with dangerous gases or chemicals. Aluminum grating does not make sparks if you drop something or walk on it. This helps stop fires and explosions in risky places. That is why you see it in oil refineries and chemical plants.
| Safety Certification | Application Area | Description |
|---|---|---|
| UL Class I Div. 1 | Oil Refineries | Non-sparking properties keep people safe in risky spots. |
| UL Class I Div. 1 | Chemical Plants | Stops fires in dangerous places. |
Aluminum grating also lasts a long time. Outside, it can last from 20 to 50 years. Good anodized panels stay strong and look nice for many years.
Low maintenance
You do not need to spend much time or money to care for it. Just clean aluminum grating with soapy water. It stays strong and clean even in wet places. Steel grating needs cleaning and painting every few years. Aluminum grating keeps working well with little care.
Tip: Aluminum grating lets air and water go through. This helps drain water and keeps floors dry and safe.
Compliance and accessories
ADA compliance
You must check that aluminum grating follows public space rules. The Americans with Disabilities Act (ADA) gives rules for walkways and ramps. These rules help people move safely. This includes people in wheelchairs or who have trouble walking. Here are the main ADA rules for aluminum grating:
- The open space in any direction cannot be more than 1/2 inch (about 13 mm).
- If the grating has long holes, turn the long side across the way people walk.
- The surface should help stop slips.
Following these rules makes walkways safer for everyone.
Tip: Always look at the grating size and direction before you put it in a public place.
Slip resistance
Slip resistance is needed for safety. You want people to walk on grating without slipping, even if it is wet or oily. Aluminum grating often has serrated surfaces. These surfaces grip shoes and help stop slips. You can use serrated grating in kitchens, factories, and outside ramps. The ADA also wants slip-resistant surfaces, so serrated aluminum grating helps you follow this rule.
Installation accessories
You need the right parts to put in aluminum grating. These parts hold the grating in place and keep it safe and strong. There are many types of clips and fasteners you can use. Here is a table that shows common installation accessories and what they do:
| Accessory Type | Description |
|---|---|
| Saddle Clip | Bent-clip fastener for removable panels, available in aluminum, stainless steel, and galvanized steel. |
| Plank Clip | Friction fastener for plank grating and embedded frames, fits ¼” flange thickness. |
| Grating Clamp | Friction fastener for bar grating, available in different metals. |
