The manufacturing process directly influences the strength, appearance, and performance of steel grating. Different production methods create unique structural characteristics for various industrial applications.
According to the manufacturing method, steel grating is available in welded grating, press-locked grating, swage-locked grating, and riveted grating. Welded steel grating is known for its strong and stable structure, while press-locked and swage-locked grating provide a clean appearance and precise surface design. Riveted grating is often used for projects requiring additional flexibility and heavy-duty performance.
With advanced manufacturing capabilities, Dunqiang supplies customized steel grating solutions in different materials, dimensions, load capacities, and surface treatments to support applications such as walkways, platforms, stair treads, drainage systems, and industrial flooring.
Swage Locked Grating

Welded Steel Grating
Welded steel grating is a strong and durable industrial flooring product manufactured by welding bearing bars and cross bars together
Types of Steel Grating by Manufacturing Process
Welded Steel Grating
Welded steel grating is the most widely used type of steel grating, manufactured by welding cross bars and bearing bars together under high pressure and temperature. The welded joints provide excellent structural stability and high load-bearing capacity.
This type of grating features a simple structure, strong durability, and easy installation, making it suitable for most industrial flooring and access applications.
Key Features:
- High strength welded structure
- Excellent load-bearing performance
- Easy fabrication and installation
- Available with galvanized, painted, or untreated surfaces
Common Applications:
- Industrial platforms
- Steel walkways
- Factory floors
- Stair treads
- Maintenance passages
Press-locked Steel Grating
Press-locked steel grating is manufactured by pressing cross bars into pre-slotted bearing bars under high pressure, creating a tight mechanical connection without welding.
This manufacturing method provides a smooth and uniform surface appearance with good load distribution. It is commonly used in architectural and industrial applications where appearance and precision are important.
Key Features:
- Smooth and attractive surface design
- Precise manufacturing structure
- Good ventilation and light transmission
- Suitable for customized patterns and sizes
Common Applications:
- Architectural platforms
- Decorative walkways
- Commercial buildings
- Industrial flooring
Swage-Locked Grating
Swage-locked grating is produced by permanently locking cross bars into bearing bars through a high-pressure swaging process. The cross bars are mechanically bonded with the bearing bars, creating a rigid and stable structure.
Compared with press-locked grating, swage-locked grating provides enhanced connection strength and a cleaner surface appearance.
Key Features:
- Strong mechanical locking structure
- High dimensional accuracy
- Excellent stability under heavy loads
- Suitable for customized spacing designs
Common Applications:
- Heavy-duty platforms
- Industrial walkways
- Power plants
- Transportation facilities
Riveted Grating
Riveted grating is manufactured by connecting bearing bars and cross bars with rivets, forming a flexible yet durable load-bearing structure. The riveted connection allows slight movement between components, improving impact resistance and vibration absorption.
It is commonly used in heavy-duty applications requiring high strength and long-term durability.
Key Features:
- Strong riveted connections
- Excellent impact resistance
- Suitable for heavy loads
- Reliable performance in demanding environments
Common Applications:
- Mining facilities
- Heavy industrial platforms
- Bridge walkways
- Transportation projects
How to Choose the Right Steel Grating Manufacturing Process?
Choosing the appropriate steel grating type depends on several factors, including load requirements, application environment, installation conditions, and aesthetic requirements.
Manufacturing Process | Main Advantages | Typical Applications |
Welded Steel Grating | Strong, economical, versatile | Industrial platforms, walkways, stairs |
Press-locked Steel Grating | Smooth appearance, precise structure | Commercial and architectural projects |
