The metal range
One Factory, Four Lines, Three Metals
Searches for metal grating for sale, grating for sale or bar grating for sale usually mean the same thing: open-mesh metal panels, cut to size and shipped on time. What actually varies is the range behind the listing. Here is everything that is for sale from this one factory — four product lines, three metals and every common finish, ordered in a single RFQ.
| Line | Construction | Mesh range | Metals & finishes | Typical duty |
|---|---|---|---|---|
| Welded steel bar grating | Bearing bars and cross bars forge-welded at every intersection | 30 / 40 / 60 mm centers | Q235B black or HDG · SS304 / SS316 passivated | Platforms, walkways, trench covers, wheel loads |
| Press-locked grating | Cross bars pressed into notched bearing bars — no weld heat | Down to 11 / 11 mm close mesh | Q235B galvanized as standard · stainless on request | Municipal trench, tree pits, facades, fine floors |
| Grating stair treads | Welded or press-locked panels, banded, with end plates | To your tread dimensions | Plain or serrated · black, primed or HDG | Industrial stairs and escape stairs |
| Stainless steel grating | Same welded construction in stainless metals | 30 / 40 / 60 mm centers | SS304 or SS316, pickled and passivated | Food, chemical and marine platforms and drainage |
Every line runs on the same bar sizes and panel limits, so mixed orders — grating, treads and covers in one shipment — are routine. Not sure which line fits your duty? Send your drawings — we will spec the metal and the process inside the 24-hour quote.
The purchase path
From RFQ to FOB Tianjin, in Four Steps
No published price list, no minimum you cannot meet — just a clear path from your first message to panels on the water. Small trial orders are welcome at any step.
1 · Send your RFQ
Panel sizes, quantities and destination — or just photos and a sketch. Drawing review is free, and it happens before anything is quoted.
2 · Itemized quote in 24 hours
FOB Tianjin as standard, EXW or CIF negotiable — itemized per m² or per ton, quote on request. We do not publish a fixed price list.
3 · Samples in 5–7 days
Check the metal, the mesh and the finish in your own hands before you commit — samples ship in 5–7 working days, HDG included.
4 · Production 15–25 days
Working days after drawing confirmation, galvanizing included. Our mill sits about 400 km from Tianjin Port — close to the FOB point your freight quotes against.
Why buy here
Factory-Direct Metal Grating, Made to Your Order
Factory-direct, small MOQ
You buy from the mill that cuts, forms and inspects the panels — no trading desk in between. Small trial orders welcome; full containers calculated per loading plan.
Grating, treads & covers in one order
Custom grating in heavy-duty or anti-slip form, matching stair treads, trench covers — one RFQ, one production window, one shipment from one factory.
Certified grating, shipped worldwide
Galvanized grating to ASTM A123 / ISO 1461 practice, mill test certificates with every heat, and grating samples in 5–7 days wherever you are based.
Applications
Where This Metal Range Sells
Same purchase path, four very different duties — pick the environment and the range narrows itself to one metal and one finish.
Platforms & walkways
Q235B welded grating plus HDG — the default outdoor specification for plant flooring and access ways.
Trench & drainage covers
Open-mesh covers for drains and gullies — close-mesh press-locked panels where heels or debris matter.
Stair treads
Banded treads in plain or serrated top, cut to your stair geometry and shipped with the flooring panels.
Food, marine & washdown
SS304 for hygiene areas, SS316 where chlorides and salt spray would pit anything less.

Metals & test documents
Whatever the metal, the paper trail is the same. 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 — and the documents travel with the goods:
- 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

ASTM A123 / ISO 1461 HDG
Galvanized coating thickness checked by sampling on every galvanized batch before panels are released for packing.
CE & SGS tested
