Aluminum Grates
Aluminum grates are load-bearing construction materials renowned for their corrosion resistance, light weight, and durability. They are widely used in both industrial and architectural settings due to their versatile features and robust construction. This article focuses primarily on aluminum bar grating, though other types such as plank grating also exist.
Primary Uses of Aluminum Grates
Aluminum grates, also known as aluminum bar grates, serve two main functions: covering openings and bearing loads. They are commonly employed on elevated catwalks, factory floors, platforms, pedestrian bridges, and stair treads. Additionally, they find unique applications in design and architecture, such as railing infill panels, sunshades, or even as set decorations in television and movies due to their industrial aesthetic.
Manufacturing Process of Aluminum Grates
Aluminum grates are crafted through a two-piece construction method. The primary component is a rectangular-shaped bearing bar, which supports the load. The secondary component, known as the cross bar or cross rod, maintains the spacing between bearing bars.
Swage-Locked Bar Grating is produced by a swaging (pinching) and forming process that locks the cross bars in place within the diamond-shaped openings of the bearing bars, preventing them from turning or twisting.
Press-Locked Bar Grating involves placing the cross bars into slots within the bearing bars and applying significant hydraulic pressure to secure them. Both methods result in a grating product that offers a high strength-to-weight ratio, minimal deflection, and maximum safety.
Advantages of Aluminum Grates
Ventilation: Grating allows for the ventilation of air, light, sound, and liquids. When used as walkable surfaces, grates prevent liquid pooling, debris accumulation, and allow heat to escape while maintaining visibility.
Strength and Durability: Aluminum grates possess a high strength-to-weight ratio, making them both lightweight and durable. They can meet a wide range of load-bearing requirements, which is particularly beneficial for elevated installations.
Long-Term Maintenance: Compared to other metal grates like stainless steel, aluminum grates are often more cost-effective. Their durability and resistance to corrosion mean they require less frequent replacement. Additionally, aluminum grates are recyclable, contributing to environmental sustainability.
ADA Compliance: Certain aluminum grates meet ADA standards for accessible design, ensuring slip resistance, proper height transitions, and appropriate opening sizes, in compliance with the Americans with Disabilities Act.
Ease of Installation: Aluminum grates are relatively easy to install due to their lightweight nature. This can reduce labor costs and installation time, making them a practical choice for large projects.
Customization: Aluminum grates can be easily customized to fit specific design requirements. This flexibility makes them suitable for a variety of unique applications, enhancing both functionality and aesthetic appeal.
Aluminum Grating Accessories
Common accessories for aluminum grates include:
- Angle: Used as a frame for railing infill panels.
- Carrier Plates: Connect cut bar grating pieces and nosing to complete a stair tread.
- Grating Clips and Fasteners: Secure the grating to supporting structures.
- Flat Bar: Often tack-welded to the grating edge for a clean and safe finish.
- Stair Tread Nosing: A 90-degree angled component designed to enhance slip resistance and visibility of steps.
Application Example of Aluminum Bar Gratings In The United States
San Francisco Bay Area Rapid Transit (BART) System
Project Overview: The BART system is a major transit network serving the San Francisco Bay Area. Aluminum grates have been used extensively in this project, particularly for walkway surfaces and platform gratings.
Applications:
Elevated Walkways: Aluminum grates are used to create safe, slip-resistant surfaces for elevated walkways and pedestrian bridges within the transit stations.
Platform Covers: They are also used on station platforms to ensure durability and resistance to corrosion from environmental factors.
Benefits: The lightweight and corrosion-resistant properties of aluminum grates make them ideal for the high-traffic, outdoor environments of the BART system.
The University of California, Los Angeles (UCLA)
Project Overview: UCLA, a prominent research university, has incorporated aluminum grates in various campus infrastructure projects to enhance both functionality and aesthetics.
Applications:
Campus Walkways: Aluminum grates are used for walkways around the campus, providing a modern look while ensuring durability and ease of maintenance.
Architectural Features: They are also employed in architectural elements such as sunshades and decorative panels, blending functionality with visual appeal.
Benefits: The use of aluminum grates at UCLA offers a balance of strength and lightweight properties, contributing to the university’s sustainable and aesthetically pleasing campus environment.
Conclusion
Aluminum grates are irreplaceable by other material grates because of its unique characteristics.
