Catwalk mesh formats
Catwalk Mesh Formats: Open, Close and Serrated
On an elevated walk the mesh opening is the whole decision: what falls through it, what the crew can see below, and how the panel feels underfoot. These are the three catwalk mesh formats we build — all three in the same factory, all cut to your drawings.
| Dimension | Open mesh 30 / 40 / 60 mm | Close mesh 11 / 11 mm | Serrated option |
|---|---|---|---|
| Mesh geometry | Welded bearing bars with twisted cross bars at open centers | Press-locked flat bars interlocked in a dense grid — no weld heat | Serrated bearing bars available in either format |
| What falls through | Rain, snow and debris drop straight through; small tools can too | Openings narrow enough that small parts and heels stay on the catwalk | Same openings as its base format |
| Open area & sight lines | Highest open area — best light, airflow and view of the level below | Dense grid reads almost solid underfoot — easier on the eyes at height | Teeth do not change the open area |
| Underfoot behavior | Classic grating tread with clearly defined bars | Even support across the whole heel line | Tooth profile adds bite on wet or oily plates |
| Typical catwalk duty | Plant walkways, pipe racks, tank access, roof catwalks | Catwalks above occupied areas and tool-carrying crews | Outdoor service, washdown areas, oil and frost zones |
| Steel per m² | Lightest format — fewer bars | More bars, more steel per square meter | Same as the base format plus tooth machining |

Mesh geometry
How Catwalk Mesh Geometry Is Built
1 · Open mesh at 30 / 40 / 60 mm
Bearing bars and twisted cross bars are resistance-forged at every intersection. This is the classic metal catwalk grating: water, snow and debris fall straight through, and the panel stays light per square meter.
2 · Close mesh at 11 / 11 mm
Flat bars are press-locked into a dense grid with no welding heat, so panels come out dead flat. The openings are small enough that spanners, bolts and work gloves stay on the catwalk instead of dropping onto people or equipment below.
3 · Serrated or plain surface
Either mesh format can be built with serrated bearing bars. The tooth profile is a geometry choice for wet, oily or frosty service — we describe it as design intent, and you can request per-batch test data with your quote. Plain bars where smooth-wheeled trolleys run or washdown matters.
Why specify catwalk mesh
Why Plant Teams Order Our Metal Catwalk Grating
Anti-slip by geometry
A metal grate catwalk stays safe through its surface, not a coating: serrated teeth in wet service, or plain welded bars for dry indoor walkways. Close 11/11 mm mesh adds even heel support on elevated runs.
Load-rated for daily traffic
Bearing bars from 20×3 mm to 100×8 mm, specified by span and traffic — maintenance crews with tool bags, not guesswork. Load tables are provided with your quote, and the 24-hour quote includes a free drawing review.
Custom sizes from small MOQ
Catwalk mesh is made to size, cut and banded to your drawings — in bulk for a full gantry or a handful of panels for one access platform. Galvanized or black, Q235B or stainless, itemized FOB Tianjin quote on request.
Applications
Where Catwalk Mesh Works
Elevated walks live or die by mesh spacing: what the crew carries, what sits underneath, and how comfortable people are looking down through the floor. Four typical duties:
Plant & equipment catwalks
Daily maintenance access over process lines — open mesh where nothing sits below, close mesh where crews work underneath.
Conveyor & pipe gantries
Long overhead runs with tools and spares in hand — 11/11 mm close mesh keeps small parts from dropping into the plant below.
Tank & silo access walkways
Outdoor catwalks in hot-dip galvanized steel — serrated mesh where plate surfaces and rain combine.
Mezzanine & platform edges
Mesh flooring and edge infill that lets light through the structure — sized and banded to each opening in your layout.

Materials & test documents
Every heat of Q235B, SS304 or SS316 enters production with its mill test certificate verified at goods-in — the first of our five QC stages. Metal catwalk grating leaves with documentation, not promises:
- Mill test certificate to EN 10204 Type 3.1
- Factory inspection report with every shipment
- Declaration of Conformity prepared per order destination

FAQ
Frequently Asked Questions
What is the lead time for catwalk mesh panels?
Samples ship in 5–7 working days and mass production runs 15–25 working days after drawing confirmation, both including hot-dip galvanizing. Rush production in 10–15 days is possible with a surcharge — ask in your quote.
Do you accept small trial orders of catwalk mesh?
Yes — small trial orders are welcome. Full-container orders are calculated per loading plan, so you only pay for the steel you ship.
How is catwalk mesh shipped and priced?
Shipped worldwide from Tianjin Port — FOB Tianjin as standard, EXW or CIF negotiable. Pricing is itemized per m² or per ton in your quote; we do not publish a fixed price list.
