Steel Grating for Industrial Platforms, Walkways and Drainage
Junhe supplies steel grating for industrial platforms, walkways, drainage systems, stair treads, steel structures, municipal projects and other applications that require durable open-grid flooring.
Our steel grating can be manufactured with different bearing bar sizes, bar spacing, panel dimensions, surface configurations and surface treatments according to project requirements. Welded and pressure-locked structures are available for different load and installation conditions, while plain or serrated surfaces can be selected according to the required walking environment.
As a steel grating manufacturer and supplier, Junhe supports both standard products and custom fabrication based on drawings, dimensions, load requirements, installation conditions and application needs.
Steel grating is widely used in factories, power plants, wastewater treatment facilities, petrochemical projects, drilling platforms, warehouses, transportation infrastructure and other industrial environments where drainage, ventilation, slip resistance and structural strength are important considerations.
Types of Steel Grating and Related Grating Solutions
Different applications require different materials, surface treatments and structural configurations. Junhe provides several grating solutions for industrial and infrastructure projects.
Hot-Dip Galvanized Steel Grating
Hot-Dip Galvanized Steel Grating is commonly selected for outdoor platforms, walkways, stair treads, drainage covers and steel structures where corrosion resistance is required.
The galvanizing process provides a protective zinc coating over the steel surface, helping reduce corrosion in humid, outdoor and industrial environments.
Common configurations can be manufactured with different bearing bar sizes and mesh spacing according to project requirements. Junhe's current product range includes common bearing bar sizes such as 20 × 5 mm, 25 × 5 mm and 30 × 3 mm, with mesh options including 30 × 100 mm, 40 × 100 mm and 60 × 100 mm.
Drainage Grating
Drainage Grating is used for drainage channels, trench covers, industrial floors, roads, platforms and other areas where water needs to pass through the surface while maintaining safe pedestrian or equipment access.
The appropriate drainage grating should be selected according to the expected load, clear span, drainage requirements, bar spacing, surface condition and installation environment.
Serrated surfaces can also be considered for wet or slippery locations where additional slip resistance is required.
Fiberglass Grating as a Non-Metallic Alternative
For projects where a lightweight and non-metallic grating solution is preferred, Junhe also supplies Fiberglass Grating.
Fiberglass grating is not a type of steel grating. It is an alternative material that may be considered for corrosive environments, chemical facilities and applications where low weight or electrical non-conductivity is important.
The appropriate choice between steel and fiberglass grating should be based on structural load, environment, corrosion exposure, installation requirements and project specifications.
Steel Grating Specifications
Steel grating performance depends on the complete combination of bearing bar dimensions, spacing, span, material and support conditions. For this reason, load capacity should be evaluated according to the actual project rather than a single universal value.
Common specification considerations include:
| Specification | Common Options or Considerations |
|---|
| Bearing Bar Size | 20 × 5 mm, 25 × 5 mm, 30 × 3 mm and other project-specific sizes |
| Bearing Bar Spacing | Selected according to load, drainage and opening requirements |
| Cross Bar Size | Different sizes available according to grating design |
| Mesh Size | Common options include 30 × 100 mm, 40 × 100 mm and 60 × 100 mm |
| Surface Type | Plain or serrated |
| Surface Treatment | Hot-dip galvanized, untreated or other available treatments |
| Material | Carbon steel or stainless steel depending on product and project |
| Panel Size | Standard or custom dimensions |
| Structure | Welded or pressure-locked depending on application |
| Load Requirement | Determined by bearing bar size, spacing, span and support conditions |
For specification-based projects, buyers should provide drawings or clearly identify the required bearing bar size, bar spacing, panel dimensions, support span and design load.
Steel Grating Applications
Industrial Platforms
Steel grating is widely used as flooring for industrial platforms because its open-grid structure allows drainage, ventilation and light transmission while providing a durable working surface.
The bearing bar size and spacing should be selected according to equipment loads, pedestrian traffic and support span.
Factory Walkways and Catwalks
Industrial walkways and catwalks require a stable walking surface while allowing liquids, dust and debris to pass through the floor.
Plain grating can be used in many general applications, while serrated steel grating may be more suitable for wet or slippery environments.
Steel Structure Flooring
Steel grating can be incorporated into structural steel projects, equipment platforms, access areas and maintenance floors.
Custom panel dimensions and cut-outs can be produced according to structural drawings and installation requirements.
Drainage and Trench Covers
Steel grating is commonly used for drainage channels and trench covers because the open structure allows water flow while maintaining access across the surface.
The required load and bar spacing should be confirmed according to whether the area is used by pedestrians, equipment or vehicles.
Stair Treads
Steel grating can also be fabricated into stair treads for industrial plants, warehouses, platforms and maintenance access systems.
Anti-slip surfaces and suitable nosing designs can be selected according to project requirements.
Petrochemical and Energy Projects
Steel grating is frequently used in refineries, drilling platforms, power plants and other energy facilities where strong, open flooring is required around process equipment and maintenance areas.
For corrosive or outdoor environments, hot-dip galvanized or other suitable corrosion-resistant configurations should be considered.
Municipal and Infrastructure Projects
Applications also include landscape walkways, wharfs, drainage systems, transportation infrastructure and other public works projects.
Junhe has supplied steel grating for industrial platforms, drilling projects, wharf drainage applications and landscape walkways.
How to Select Steel Grating for Your Project
Selecting the right steel bar grating requires more than choosing a panel size. The structural and environmental requirements of the installation should be reviewed first.
1. Determine the Required Load
Identify whether the grating will support:
The required bearing bar size cannot be determined accurately without considering both load and support span.
2. Confirm the Support Span
The distance between structural supports has a major influence on grating performance.
A longer span generally requires a stronger bearing bar configuration, so the clear span should be included when requesting a quotation.
3. Select Bearing Bar Size
Bearing bar height and thickness affect the structural capacity of the steel grating.
For example, a 30 × 3 mm bearing bar and a heavier bearing bar cannot be treated as equivalent simply because they use the same mesh spacing.
4. Choose the Appropriate Bar Spacing
Spacing affects:
Open area
Drainage
Walking comfort
Load distribution
Small-object retention
Overall panel weight
Specifications such as 30/100 and 40/100 typically describe different bar-spacing arrangements and should be selected according to application requirements.
5. Select Plain or Serrated Surface
Plain steel grating is suitable for many general industrial applications.
Serrated grating provides additional surface grip and may be preferred for ramps, wet areas, drainage zones and other locations where slip resistance is a concern.
6. Consider Corrosion Protection
Outdoor, marine, chemical and high-humidity environments may require additional corrosion protection.
Hot-dip galvanized steel grating is commonly considered for these applications, while stainless steel may be suitable for selected projects requiring higher corrosion resistance.
7. Provide Drawings and Project Requirements
For custom projects, provide as much information as possible, including:
Panel dimensions
Bearing bar size
Bar spacing
Clear span
Required load
Surface type
Surface treatment
Cut-outs
Installation drawings
Quantity
This helps the manufacturer evaluate the appropriate configuration before production.
