Steel grating is one of the most widely used flooring solutions for industrial walkways, platforms and access systems. Its open design provides excellent drainage, ventilation and slip resistance while maintaining strong load-bearing performance.
However, like all structural access systems, steel grating requires periodic inspection and maintenance to ensure it continues to perform safely throughout its service life.
Many industrial access structures are designed to align with the intent of AS/NZS 1657:2018, which outlines requirements for the design and installation of fixed platforms, walkways, stairways and ladders used for operational and maintenance access.
While steel grating products are commonly used in these structures, the responsibility for inspection, maintenance and ongoing compliance rests with the asset owner or operator.
Below are key considerations that may assist asset owners when developing steel grating inspection and maintenance programs.
Why Steel Grating Inspection Is Important
Industrial walkways and platforms are exposed to a wide range of environmental and operational conditions including:
- heavy foot traffic
- vibration from nearby equipment
- corrosive industrial environments
- exposure to chemicals or washdown processes
- impact from tools or mobile equipment
Over time these conditions can affect both the grating panels and their supporting structure. Regular inspection helps identify issues early and reduces the likelihood of unexpected failures or safety hazards.
Establish a Steel Grating Inspection Program
A structured inspection program is one of the most effective ways to maintain safe industrial walkway grating systems.
Asset owners commonly consider:
- conducting steel grating inspections at least annually by a competent person
- increasing inspection frequency in corrosive, marine or chemical environments
- carrying out additional inspections after events such as:
- equipment impacts
- overload events
- chemical spills
- fire exposure
- structural modifications
Documenting inspections can also help track changes in condition over time.
What to Look for During a Steel Grating Inspection
When inspecting industrial grating walkways, several key conditions are often reviewed.
Check for Bent or Damaged Load Bars
Load bars provide the primary structural strength of a grating panel.
Inspectors may look for:
- bent or twisted load bars
- deformation from impacts or overload
- panels that appear uneven or unstable under foot traffic
Any deformation may affect the load capacity of the grating.
Identify Corrosion or Coating Damage
In many industrial facilities, grating is supplied as galvanised steel grating to provide corrosion protection.
Inspection may include checking for:
- coating degradation
- pitting corrosion
- rust formation
- material section loss
Early identification of corrosion can help extend the service life of the installation.
Check Grating Clips and Fixings
Grating panels rely on clips or fasteners to remain securely positioned during use.
Inspection may include confirming that:
- all grating clips are present
- fixings remain tight
- fasteners are not heavily corroded
- panels cannot shift or uplift during normal use
Missing or damaged clips can lead to panel movement and should typically be addressed promptly.
Verify Adequate Support of Grating Panels
Industrial grating systems rely on support beams, frames or concrete ledges to distribute loads.
Inspections may verify that:
- grating panels maintain adequate end bearing on supports
- support steelwork shows no signs of deformation or corrosion
- there is no structural damage to the supporting structure
Support locations are often areas where corrosion and debris accumulation occur, so these areas may warrant particular attention.
Watch for Field Modifications to Grating Panels
In operating facilities, grating panels are sometimes modified to allow for:
- pipe penetrations
- equipment supports
- service access openings
These modifications may include cutting load bars or trimming panels.
Because field modifications can affect structural performance, asset owners may wish to verify that alterations have been appropriately engineered or approved.
Maintain Clean Grating Walkway Surfaces
Keeping industrial grating walkways clean can help maintain both corrosion resistance and slip safety.
Routine cleaning may involve removing materials such as:
- soil or dust
- leaves and organic matter
- sludge or process scale
- grease or oil residues
- salts or chemical deposits
Debris accumulation between grating panels and support members may also accelerate corrosion and should typically be managed as part of maintenance programs.
Managing Slip Resistance on Industrial Grating
Slip risk can increase when grating becomes contaminated by liquids, oils or process materials.
Facilities often manage this risk by:
- promptly cleaning spills
- maintaining good drainage through the grating
- regularly inspecting areas exposed to wet processes or washdown
Maintaining adequate slip resistance supports safe access conditions for workers using platforms and walkways.
Cleaning Galvanized Steel Grating
Where galvanized steel grating is installed, cleaning methods that are compatible with zinc coatings are typically preferred.
Asset owners may consider:
- avoiding aggressive mechanical cleaning that may damage coatings
- limiting exposure to harsh chemicals where possible
- rinsing grating surfaces after exposure to cleaning agents
Appropriate cleaning helps preserve the protective zinc layer and extend the service life of the grating.
When to Replace Steel Grating Panels
Over time, some grating panels may require replacement.
Replacement may be considered where inspections identify:
- significant corrosion or section loss
- cracked welds or broken cross bars
- major deformation of load bars
- compromised structural integrity
Where uncertainty exists regarding structural performance or load capacity, assessment by a qualified engineer may be appropriate before returning the area to service.
Maintaining Safe Industrial Walkways
Steel grating remains one of the most reliable and durable solutions for industrial walkways, platforms and access flooring.
With appropriate inspection and maintenance practices, grating installations can continue to provide safe and effective access for many years.
