Platform grating is an open flooring system used to create working surfaces on elevated platforms, maintenance areas, access structures and industrial walkways. The open construction allows water, light, air and small debris to pass through while the bearing bars provide structural support.
A grating platform can be designed around the expected pedestrian or operational load, support span, material and installation environment. Unlike solid plate flooring, grating can help reduce water accumulation and improve drainage in areas exposed to rain, cleaning water or process fluids.
Platform grating is available in several configurations. AMMS Global's Bar Grating range includes welded bar grating, press-locked grating, aluminium bar grating and stainless steel grating options.
Types of Platform Grating
Steel Bar Grating Platform
A steel bar grating platform uses load-bearing bars supported by cross bars to create an open structural surface. Steel is commonly considered for industrial platforms where strength and durability are important.
A bar grating platform can be specified with different bearing bar sizes, spacing and surface profiles depending on the application. Serrated surfaces can provide additional traction where moisture, oil or other contaminants may be present.
Galvanized Steel Grating Platform
A galvanized steel grating platform provides additional corrosion protection compared with untreated carbon steel. It can be considered for outdoor platforms, access structures and industrial areas exposed to moisture.
The appropriate finish should be selected according to the environment, expected service conditions and project specification.
Metal Grating Platform
A metal grating platform can be manufactured from different metals depending on the required performance. Carbon steel can suit general industrial applications, while stainless steel and aluminium can be considered where corrosion resistance, weight or environmental conditions are important factors.
FRP Grating Platform
An FRP grating platform uses fiberglass reinforced plastic rather than conventional steel. FRP can be useful in environments where corrosion and chemical exposure are significant concerns.
A fiberglass grating platform may be considered for chemical processing areas, water treatment facilities and other locations where a non-metallic grating solution is required.
Platform Grating Applications
Platform grating is used across industrial environments where personnel need access to equipment, elevated work areas or maintenance zones.
Industrial Platforms
Industrial platform grating provides an open working surface around machinery, tanks, production equipment and process systems. The open construction allows liquids and debris to pass through the floor rather than remaining on a solid surface.
Walkways and Access Areas
Grating can form elevated walkways between equipment or provide access to areas that require regular inspection and maintenance. Surface selection is particularly important where water, oil or other contaminants could affect underfoot traction.
Offshore Platform Grating
Offshore platform grating must be selected with particular attention to corrosion exposure, loading, drainage and surface traction. Marine environments can expose steel products to saltwater and high humidity, making material selection and protective treatment important considerations.
For offshore applications, the final specification should be established from the project's structural, environmental and applicable regulatory requirements rather than relying on a generic grating specification.
Maintenance Platforms
Grating platforms are also used around industrial equipment where maintenance teams need safe access to valves, pumps, machinery and elevated components.
Platform Grating Material Comparison
Material Type | Best For | Key Strength |
Carbon Steel | General industrial platforms and access areas | Strength and structural performance |
Galvanized Steel | Outdoor and moisture-exposed platforms | Added corrosion protection |
Stainless Steel | Corrosive and hygiene-sensitive environments | Corrosion resistance |
Aluminium | Applications where lower weight is important | Lightweight construction |
FRP / Fiberglass | Chemical and highly corrosive environments | Corrosion and chemical resistance |
The actual material should be selected according to the application, support arrangement, loading, environment and required service life.
Load Capacity and Open Area
Platform grating should not be selected based on material alone. Load capacity depends on factors such as bearing bar dimensions, bearing bar spacing, cross bar arrangement, panel span, support conditions and the type of load applied.
For example, a platform intended only for pedestrian access will have different requirements from one carrying maintenance equipment or regularly supporting industrial loads.
Open area is another important characteristic. The percentage of open space in the grating affects drainage, ventilation and visibility through the platform. A suitable balance between open area and structural requirements should be established during specification.
For project enquiries, providing the platform dimensions, support span, expected load, material preference and operating environment helps AMMS Global determine an appropriate grating configuration.
Platform Grating vs Floor Grating
Platform grating and floor grating can use similar products, but the terms generally describe different applications.
Platform grating usually refers to grating used as the working surface of an elevated platform or access structure. Structural loading and support span can therefore be particularly important.
Floor grating is a broader term that can describe grating used for industrial floors, walkways, drainage areas, trench covers and other ground-level or elevated surfaces.
The same bar grating product may be suitable for both applications when its dimensions, load capacity and support arrangement meet the project requirements.
How to Choose Platform Grating
Start with the application rather than the product name. Consider:
Expected load: Determine whether the platform will carry pedestrians, equipment or other operational loads.
Span and support: The distance between supports affects the required bearing bar specification.
Material: Select steel, galvanized steel, stainless steel, aluminium or FRP according to the environment.
Surface: Serrated surfaces can provide additional traction in wet or contaminated areas.
Open area: Consider the drainage, ventilation and visibility requirements.
Environment: Outdoor, marine, chemical and high-moisture locations may require specific materials or finishes.
Dimensions: Panel length, width and required cut-outs should be established before fabrication.
AMMS Global can work from project dimensions and application requirements when a specific grating configuration is needed.

Frequently Asked Questions
What is the weight of a grating platform?
There is no single standard weight for a grating platform. Weight depends on the material, panel dimensions, bearing bar size, bearing bar spacing, cross bar arrangement and overall construction. Larger bearing bars and closer spacing generally increase the weight of the panel. The project dimensions and specification should be used to determine the actual weight.
What are the different types of grating available?
Industrial grating is available in different materials and construction types. Common options include welded steel bar grating, press-locked grating, stainless steel grating, aluminium grating and FRP or fiberglass grating. The appropriate type depends on the required load performance, corrosion resistance, weight and operating environment.
What are the two types of grating?
Two common construction methods are welded grating and press-locked grating. Welded grating uses welded cross bars to connect the bearing bars, while press-locked grating uses mechanically locked connections. Other grating categories, including molded FRP grating and formed safety grating, use different manufacturing methods.
What is the working principle of a grating?
Grating creates a load-bearing open surface through a network of bearing bars and cross members. The bearing bars carry the primary load while the cross members maintain the spacing and stability of the panel. The openings allow water, air and debris to pass through the surface.
