Sizing & duty
Size the Grating to the Gully — and to What Runs Into It
A gully is a point where the floor gives up its worst water. In a food plant that is washdown and fats; in a chemical bay it is corrosive spill heading for the interceptor. The stainless steel gully grating has to fit the chamber exactly and survive what passes through it — so sizing and grade are one decision, made together.
| Gully duty | What runs through it | Cover sized to the chamber | Grade |
|---|---|---|---|
| Food plant floor gully | Daily washdown, fats, detergents, small solids | Rectangular 304 stainless steel drain grid to the clear opening, close mesh where solids are fine | SS304 |
| Chemical bay & interceptor gully | Corrosive spills routed to the sump before discharge | Square or rectangular grid, banded edge seated flat all round | SS316 |
| Equipment & vehicle wash bay | Constant water plus trolley or wheel loads | Heavy bar sections over the chamber, clear opening plus bearing edge | SS304 or SS316 |
| Stainless steel outdoor drain | Rainwater, de-icing salt, coastal chloride spray | Circular or square top, mill finish that needs no coating | SS316 |
How to measure a gully for a stainless cover
Send three numbers per gully: the chamber's clear opening (length × width), the seat depth the cover rests on, and the traffic that crosses it — foot, trolley or vehicle. We cut and band each SS gully grate to sit flat with a bearing edge all round; square, rectangular and circular tops are all made to order, any length of run and any project quantity.

Load framing
Foot, Trolley or Vehicle — the Gully Cover Follows the Wheels
The same chamber can sit in a pedestrian corner or a truck crossing. Load classes below are referenced to EN 124; state your traffic in the RFQ and we match the bearing bar section to it within our standard spec range.
| Class (referenced to EN 124) | Traffic over the gully | Recommended grating spec |
|---|---|---|
| A15 | Pedestrians only — foot traffic across the cover | Light bearing bars from 20×3 mm, 30 / 40 mm spacing, close mesh to 11/11 mm where small solids flow |
| B125 | Trolleys, pallet trucks, kerbside parking | Mid bars around 30×3 to 40×4 mm on 30 / 40 / 60 mm centers, banded edges |
| C250 | Cars and delivery vehicles in yards and bays | Bars from 40×4 toward 50×5 mm, 30 / 40 mm centers, heavy banding |
| D400 | Trucks, forklifts and heavy plant crossings | Heavy sections up to 100×8 mm on close centers — heavy duty gully grating built to last |
Actual load tables for your exact chamber size are provided with your quote — send the drawing and the wheel load, and the calculation comes back itemized.
How a gully cover is specified
From Gully Chamber to Stainless Cover
1 · Chamber & seat
The gully chamber sets everything: clear opening, seat depth and where the water arrives. We confirm the cover outline against your chamber dimensions before any bar is cut.
2 · Grating selection
Bar height and spacing follow the load crossing the gully — foot, trolley or vehicle. Close mesh keeps the open area a gully needs while holding back small solids, so storm water passes and the interceptor works as designed.
3 · Fabrication & export
Stainless needs no galvanizing — covers are cut and banded to drawing, welds dressed, then strapped and palletized with their mill certificates for the run to Tianjin Port.
Why specify stainless gully gratings
Why Corrosive Sites Specify Stainless Steel Gully Grating
High flow, heavy duty
Open-mesh SS gully grating handles storm water and truck wheels alike — the open area keeps the gully draining while heavy bar sections take whatever crosses the chamber.
Built to last in corrosive duty
Washdown chemistry eats coatings off carbon covers; a stainless gully grating in SS304 or SS316 keeps its section and stays serviceable — the grade you pick for the effluent, not for looks.
Covers, frames and grates from one factory
Factory-direct from the mill in Shijiazhuang — no middlemen — and made to spec: gully gratings to your drawings, any size and any length, with small trial orders and wholesale quantities both welcome.
Applications
Where Stainless Gully Gratings Earn Their Keep
A galvanized gully grid covers most civil drainage. The stainless steel gully grating takes over wherever what enters the chamber would attack a coated cover — or wherever hygiene rules refuse rust streaks.
Food plant gullies
A 304 stainless steel drain grid at every washdown point — fats and detergents daily, close mesh for small solids.
Chemical bays & interceptors
Corrosive spills route through SS316 gully gratings to the interceptor — the cover survives the same chemistry as the sump.
Equipment & vehicle wash bays
Constant water plus wheel loads — heavy SS bar sections over the chamber, sized to the seat.
Outdoor & coastal gullies
A stainless steel outdoor drain where chloride spray and de-icing salt strip coatings year after year.

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

FAQ
Frequently Asked Questions
How do I size a stainless steel gully grating to my chamber?
Measure the gully chamber's clear opening (length × width) and the seat depth, then send both with your load requirement. Each cover is cut and banded to sit flat on the seat with a bearing edge all round — square, rectangular or circular tops are all made to order.
SS304 or SS316 for a gully in a corrosive plant?
SS304 handles food plant washdown, fats and general detergents. SS316 adds molybdenum for chlorides and harsher cleaning chemicals, so it is the usual choice for chemical bays, interceptors and coastal outdoor drains. Both grades run on the same bar and mesh range — the choice is about environment, not strength.
What are the lead time, MOQ and shipping terms?
Samples ship in 5–7 working days and mass production runs 15–25 working days after drawing confirmation. Small trial orders are welcome. Gully gratings ship worldwide from Tianjin Port — FOB Tianjin as standard, EXW or CIF negotiable — with mill test certificates (EN 10204 Type 3.1) in the paperwork.
