Selection guide
Non-Slip Selection by Hazard Zone: Wet, Oily, Frost, Ice
Start from what lands on the floor, then choose the geometry, then the metal. Non-slip on this page means surface design — teeth, edges and spacing described geometrically, never a slip-test rating. This is the matrix we work through with your drawings.
| Hazard zone | What the floor fights | Geometry we spec | Metal & finish we pair |
|---|---|---|---|
| Wet zones | Rain-exposed platforms, washdown bays, process water | Serrated tops as the default — the open mesh lets water drain straight through while the teeth keep their bite | Q235B hot-dip galvanized for outdoors; SS304 where floors are hosed daily |
| Oily zones | Mills, press shops, lube and coolant spillage | Serration combined with closer mesh — more toothed edges under the same sole; site-applied grit coating accommodated per project | SS304 for solvents and degreasers; Q235B HDG where the oil sits outdoors |
| Frost zones | Overnight frost film on stairs, ramps, escape routes | Serrated tops with galvanizing — the tooth profile breaks the thin frost film, and open mesh sheds meltwater instead of pooling it | Q235B hot-dip galvanized to ASTM A123 / ISO 1461 |
| Ice zones | Winter yards, freezer thresholds, exposed bridges | The combination route — serration with closer centers so the sole always meets toothed steel; de-icing access planned into the fixing layout | Q235B HDG as standard; SS316 for marine-exposed and brine-spray decks |
Tell us the zone and send your drawings — we will spec geometry and metal inside the 24-hour quote.
How the geometry grips
The Geometry Behind a Non-Slip Metal Surface
Three levers decide how a metal floor behaves underfoot. All of them are cut into the steel, not sprayed onto it.
1 · Serration depth framing
The teeth are sheared into the top edge of the bearing bar in the same pass that sizes the bar. The tooth profile stands proud of the bar body, so under load the sole deforms over the steel and interlocks with it — the height comes from the cut, not from an added layer that can wear or peel.
2 · Close mesh
Press-locked panels run openings down to 11 / 11 mm. More bars under the same footprint means more steel edges in contact with the sole — and heels or small wheels stay on the surface instead of dropping into the mesh.
3 · The combination
Serration and close spacing stack: every bar underfoot is a toothed bar, so the sole lands on steel edges that bite even where a film of water, oil or melt frost sits on the panel. This is the route we default to for ice-prone duty.
Why specify non-slip
Why Specifiers Choose Non-Slip Metal Grating
A surface that grips
Non-slip metal teeth bite wet or oily soles — fewer slips, fewer incidents on site, and a walking surface that behaves the same on a rainy ramp as on a dry platform.
Made to spec, any size
Non-slip metal surfaces, serrated or plain, cut to your sizes — from a single tread to heavy-duty non-slip panels, custom-made with free drawing review inside the 24-hour quote.
Mill cert with every order
Certified & tested, reports on request. The steel behind the teeth carries an MTC to EN 10204 Type 3.1, and galvanized coating thickness is checked by sampling on every batch.
Metal chooser
Which Metal for Your Zone: Q235B, SS304 or SS316
Geometry handles the grip; the metal handles the environment around it. All three run through the same four product lines, in the same spec ranges.
Q235B + hot-dip galvanizing
The outdoor default for wet, frost and ice zones — platforms, stairs, ramps and walkways. Galvanized to ASTM A123 / ISO 1461 at a certified partner plant near our mill, with coating thickness checked on every batch.
SS304 for washdown duty
Food processing, beverage and chemical plants where floors are hosed daily and solvents strip lesser finishes. Stainless keeps the tooth geometry clean and bright for the life of the floor.
SS316 for marine chloride
Offshore walkways, coastal platforms, brine-spray and de-icing salt zones. The added molybdenum holds up where chlorides attack, keeping the serrated surface in service longer.

Materials & test documents
Non-slip is geometry — the paperwork covers the steel and the coating behind the teeth. 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. Panels leave 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
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.
CE & SGS tested
Certified & tested, reports on request — material and coating documents you can verify, not a certificate wall.

FAQ
Frequently Asked Questions
How does non-slip metal grating work?
By geometry, not by coating chemistry. Serrated teeth are sheared into the top edge of each bearing bar, so the sole deforms over the tooth profile and interlocks with the steel instead of riding on a flat bar. Close mesh puts many more bar edges under the same footprint. Non-slip here is a surface-design goal described geometrically — we do not publish slip-test ratings.
Which metal should I pair with my hazard zone?
For wet, frost or ice zones outdoors, Q235B carbon steel with hot-dip galvanizing to ASTM A123 / ISO 1461 is the standard pairing. For daily washdown in food or chemical plants, specify SS304 stainless. For marine and chloride exposure — offshore decks, coastal platforms, brine areas — SS316 is the choice. We confirm the geometry-and-metal pairing for your zone inside the 24-hour quote.
What sizes and lead times apply, and can I sample first?
Bearing bars run from 20×3 mm to 100×8 mm with 30 / 40 / 60 mm welded centers or press-locked mesh down to 11 / 11 mm; panels measure up to 1.25 m wide and 6 m long, cut and banded to your drawings. Samples are ready in 5–7 working days, mass production runs 15–25 working days after drawing confirmation, and your quote lands within 24 hours.
