Welded Bar Grating is a rigid open-grid flooring product made by welding load-bearing bars to perpendicular cross bars. The welded intersections create a stable panel that can be used where industrial floors and access surfaces need strength with an open design.
The W-19-4 configuration uses 19mm bearing bars with a 30mm bearing bar pitch. AMMS Global manufactures this product in carbon steel with mild steel and hot-dip galvanized finish options.
W-19-4 Welded Bar Grating Specifications
The W-19-4 product is designed for industrial applications where a strong metal grating surface is required. Its resistance-welded construction keeps the bearing bars and cross bars securely joined at each intersection.

The exact load capacity depends on bearing bar dimensions, span, support conditions and the applied load. Engineering selection should therefore be based on the project requirements rather than product designation alone. Standard W-19-4 grating terminology commonly identifies welded construction with bearing bars at approximately 1-3/16 inch centers and cross bars at 4 inch centers.
Why Choose Welded Steel Bar Grating?
Welded steel bar grating is widely used for industrial flooring because the welded construction provides a rigid panel with an open surface. The openings allow water, debris and other materials to pass through instead of collecting across a solid floor.
The open structure can also support airflow and visibility beneath platforms. This makes welded grating useful for elevated access areas where drainage and ventilation are important alongside structural performance.
For applications exposed to weather or moisture, hot-dip galvanizing can provide additional corrosion protection. The appropriate finish should be selected according to the operating environment and maintenance requirements.
Heavy Duty Welded Bar Grating for Industrial Applications
Heavy duty welded bar grating is commonly selected for platforms and access areas that experience substantial foot traffic or industrial loading. The suitable bearing bar size and panel configuration depend on the required span and load conditions.
The W-19-4 product is suited to platforms, walkways, catwalks and drainage covers in oil and gas, petrochemical and general industrial facilities.
For broader product requirements, Bar Grating provides access to other grating configurations that can be selected according to span, loading, surface and application requirements.
Where Is W-19-4 Grating Used?
W-19-4 grating can be used across a range of industrial access and flooring applications. The open grid construction is particularly useful where water drainage and airflow are required.
Common applications include:
Industrial walkways
Elevated platforms
Catwalks
Maintenance access areas
Equipment platforms
Drainage covers
Industrial flooring
Plant access structures
The product page identifies oil and gas facilities, petrochemical facilities and general industrial environments among its intended applications.
Welded Bar Grating vs Other Grating Options
Welded Bar Grating is one option within a broader range of industrial grating products. The right selection depends on the material requirements, environment, loading conditions and intended use.
For lightweight applications or corrosive environments, other materials may be more appropriate. Aluminium Grating can be considered where reduced weight and corrosion resistance are important. Stainless Steel Grating is suitable for applications where corrosion resistance and hygiene requirements are more demanding.
For non-metallic applications, Fiberglass Grating provides an alternative where corrosion resistance or electrical insulation is required. For access flooring requirements, Platform Grating and Floor Grating cover related industrial applications.
How Do You Select the Right Welded Bar Grating?
Start by identifying the required span and loading conditions. Bearing bar dimensions should then be selected based on the structural requirements of the installation.
The operating environment is another important consideration. Carbon steel can be suitable for many industrial applications while a hot-dip galvanized finish can be specified where greater resistance to atmospheric exposure is required.
Surface requirements should also be reviewed. Areas exposed to oil, water or other slippery substances may require a suitable anti-slip grating configuration rather than a standard smooth surface.
The installation method and panel dimensions should be confirmed before ordering. Support conditions and fastening requirements can affect the final performance of the grating system.

Frequently Asked Questions
What does W-19-4 mean in welded bar grating?
W-19-4 is a standard grating designation used to describe a welded grating configuration. The W identifies welded construction while 19 refers to the bearing bar spacing designation and 4 identifies the cross bar spacing.
Is welded bar grating suitable for outdoor applications?
Yes. Welded bar grating can be used outdoors when the material and finish are selected for the environment. Hot-dip galvanized carbon steel is one option where additional protection against atmospheric corrosion is required.
What is the difference between welded and press-locked bar grating?
Welded bar grating joins bearing bars and cross bars through welding at their intersections. Press-locked grating uses mechanical pressure to lock the cross bars into the bearing bars, creating a different construction method and surface appearance.
What information is needed to specify welded bar grating?
Important information includes the required span, design load, bearing bar size, panel dimensions, material, finish and support conditions. These details help determine the appropriate grating configuration for the intended application.
