Stainless steel grating is a strong, adaptable material used in many industries. Because it’s resistant to corrosion, easy to clean, and aesthetically pleasing, it’s a popular choice for demanding environments.
This article will provide an overview of SS grating, including the different types available and their common applications.
Understanding Stainless Steel Bar Grating
Stainless steel bar grating is often used in places that need to be both strong and sanitary. Here’s a quick look at the material and its components:
Material Properties and Advantages
- Alloys: Types 304, 304L, 316, and 316L are commonly used.
- Corrosion resistance: Stainless steel is ideal for harsh and sanitary environments because it resists corrosion.
- Applications: You’ll often see stainless steel bar grating in architecture, industry, and the food processing industry.
Key Components
- Bearing bars: These are the main components that carry the load.
- Cross bars: These connect the bearing bars and keep everything stable.
Common Spacing
- Bearing bar spacings typically range from 19/16” (1-3/16”) to 7/16” on center.
- Cross bar spacings are usually 4” or 2” on center.
Different Ways to Make Stainless Steel Grating
Stainless steel grating can be manufactured in a few different ways, depending on the application. Here’s a look at three common types:
Welded Stainless Steel Grating (WS)
With welded stainless steel grating, the components are forge welded together, creating a strong and economical bond. This type of grating is the strongest and most affordable of the three and is often used for industrial flooring and walkways.
Swage Locked Stainless Steel Grating (SLS)
In swage locked stainless steel grating, cross bars are hydraulically swaged to create a secure connection. This type of grating is ideal for close-mesh applications, including those designed to comply with ADA guidelines and pedestrian safety requirements.
Dovetail Pressure Locked Stainless Steel Grating (DTS)
For dovetail pressure locked stainless steel grating, the deep rectangular cross bars are pressure-locked into the bearing bars. This type is often chosen for its aesthetic appeal and is a favorite for architectural designs, facades, and decorative elements.
Specifications and Considerations
When choosing stainless steel grating, there are several things to keep in mind:
- Bearing bar size and spacing: This impacts how much weight the grating can hold and how much open space there is.
- Cross bar size and spacing: This affects the stability of the grating and how it looks.
- Finish options: You can choose from mill finish, polished, electro-polished, or passivated finishes.
It’s also important to consider the specific application. What kind of load will the grating need to support? Does it need to meet ADA compliance? How resistant to corrosion does it need to be?
Key Takeaways
Stainless steel grating is durable, versatile, and useful in many applications. Choosing the right type and specifications for your project is important; consider your specific needs and the look you want to achieve.
While the initial investment may be higher than with other materials, stainless steel grating offers reliable performance and long-term value.
