Close-mesh steel grating for small openings
Finer-opening grating for pedestrian-friendly and public/commercial use. Heel-proof design, small-object retention.
Finer bearing and cross spacing than standard grating — smaller openings for pedestrian and public areas (heel-proof / small-object retention). Welded or press-locked per order. Specify target opening or standard in your RFQ; see spacing guide.

Close-mesh deployment contexts
Data centers
Walkways above sensitive cable zones where small hardware must not fall through open mesh.
Power generation
Platforms above rotating equipment or conveyors where owner standards limit opening size.
Oil & gas
Offshore cellar decks and modules referencing dropped-object programs alongside walkway use.

Frequently asked questions
How is close-mesh different from standard pitch?
Bearing bars and/or cross bars are spaced tighter, shrinking openings and increasing steel weight per square metre.
Does close-mesh affect drainage?
Yes—open area drops; hydraulic designers should confirm run-off where washdown or rain loads exist.
Is close-mesh suitable for public walkways?
Often yes when openings must limit high-heel intrusion; cite the governing rule set in the RFQ.
Can it be galvanized?
Yes with standard venting practices for trapped pockets.
What loads apply?
Same span/load methodology as other welded meshes—use released tables.
When is composite used instead?
When zero open area is required, consider composite grating.
