Which Bar Grating Do You Need?
People type this product a dozen ways — bargrate, bar grading — whatever spelling you use, this is the panel: parallel bearing bars locked with cross bars into an open steel mat. You do not need the jargon to order it. Start from the job below, and we handle bar sizes, centers and finish in the quote.
| The job | Bearing bars | Bar centers | Surface | Read more |
|---|---|---|---|---|
| Walkways & catwalks, foot traffic | Plain bars, from 20×3 mm | 30 mm | Serrated optional for wet floors | Floor Grating |
| Platforms & mezzanines | Heavier bars, up to 100×8 mm | 40 / 60 mm | HDG for outdoor duty | Grated Floor Panel |
| Trench & drain covers | Plain bars, from 20×3 mm | 30 / 40 mm | HDG, small openings | Grating Mesh |
| Public floors, heel-proof | Press-locked bars | Close mesh 11 / 11 mm | HDG or stainless | Metal Mesh Grating |
| Wheel traffic & ramps | Up to 100×8 mm, serrated | 40 / 60 mm | HDG, anti-slip | Heavy-Duty Grating |

How to order
From Sketch to Container in Three Moves
1 · Send what you have
A drawing, a marked-up photo of the old panels, or just dimensions typed into a message. Rough is fine — drawing review is free and part of every quote.
2 · We spec it, quote in 24 hours
Back comes a spec: bar size, centers, finish, banding, fixing layout — itemized, FOB Tianjin as standard. Small trial orders are welcome, so you can test before you scale.
3 · Samples, production, documents
Samples in 5–7 working days, production 15–25 after drawing confirmation — HDG included. Five-stage QC, then MTC and inspection report travel with the goods.
Why buy this way
Why Buyers Order Bar Grating Factory-Direct
Factory-direct FOB pricing
You buy from the mill in Shijiazhuang, not a trading desk. Every order is quoted factory-direct FOB Tianjin and itemized — per m² or per ton, no hidden layers.
Custom sizes from a small MOQ
Stock designations like 19W4, or panels cut and banded to your drawings. Custom bar grating starts from small MOQ — order the quantity the job needs, not a container more.
Anti-slip and heavy-duty options
Serrated bearing bars for wet or oily floors, plain bars for dry interiors, bars up to 100×8 mm for wheel loads. Stainless SS304 / SS316 when the environment eats carbon steel.
Applications
Where Bar Grating Ends Up
Open mesh lets water, light and air through while the steel carries the load. Four jobs cover most bar grating orders we quote.
Plant platforms
Load-rated flooring around machines and on mezzanines.
Walkways & catwalks
Drains rain and spills underfoot, so the walking line stays clear.
Trench & drain covers
Covers that let process water through and keep the surface safe.
Stair treads
Bar grating treads with serrated or plain surface and nosing.

Materials & test documents
You do not have to take our word for the steel. Every heat of Q235B, SS304 or SS316 is checked against its mill test certificate at goods-in, and the paperwork follows the panels:
- Mill test certificate to EN 10204 Type 3.1
- Factory inspection report with every shipment
- Declaration of Conformity prepared per order destination
Standards & compliance
Produced to Recognized Standards — Documents on Request
ANSI / NAAMM MBG 531
Bar grating produced to MBG 531 reference practice, with joint inspection on our five-stage QC plan.
ASTM A123 / ISO 1461 HDG
Hot-dip galvanized coating thickness checked by sampling on every galvanized batch before panels are released.
CE & SGS tested
Certified & tested, reports on request — you get documents you can verify, not a certificate wall.
