Load class guide
Pick the Grating Before You Pour the Channel
On a 1 m module the grating is the structural lid: bearing bars span across the channel and carry whatever crosses it. Class the traffic first, then the channel body and cover follow from one specification. Classes below are referenced to EN 124 — panels are produced to the class you specify.
| Load classreferenced to EN 124 | Typical traffic | Grating spec we quote | Where it sits in the run |
|---|---|---|---|
| A15 | Pedestrians, bicycles | 20×3 / 25×3 mm bearing bars, 30–40 mm centers | Patios, footpaths, roof perimeter channels |
| B125 | Cars, light vans | 30×3 / 40×4 mm bearing bars, 30–40 mm centers | Parking bays, driveway edges, yard doors |
| C250 | Kerbside traffic, delivery vans | 40×4 / 50×5 mm bearing bars, 30–40 mm centers | Kerb lines, forecourt margins, service yards |
| D400 | Trucks and HGV wheels | 50×5 up to 100×8 mm bearing bars, 30 mm centers, banded edges | Road crossings, loading bays, washdown aprons |

Coverage planning
One Spec: 1 m Channel Runs + Grating Covers
1 · The matched module
Each module pairs a 1 m channel body with a cover cut and banded to the same opening. Coverage is simple arithmetic: run length divided into modules, with cover panels numbered to drop straight onto their section.
2 · Runs, end caps & outlets
Mark outlet positions and slope direction on your layout. We confirm module count, end caps and outlet placement in the drawing review, so the water path and the grating layout are decided in one pass — not reconciled on site.
3 · Load framing
Bearing bars run across the channel and land on the support edges or companion frames each side — the span is the channel width, not the run length. That is why one heavy class crossing sets the bar height for its whole module.
Why specify this module
Heavy Duty, High Flow, Any Length
Truck wheels, not just rain
Heavy-duty modules take bearing bars up to 100×8 mm on 30 mm centers with banded edges — the same steel grating we weld for industrial platforms, framed into a channel run.
High-flow storm water
Open mesh at 30 / 40 / 60 mm centers lets storm water straight through and sheds debris at the surface — the channel carries the flow, the grate keeps the surface trafficable.
Any run length, made to spec
Covers, frames and grates quoted as one package from one factory, factory-direct with no middlemen — modules cut to your drawings so straight runs, corners and outlet sections all arrive together.
Applications
Where 1 m Channel Modules Work
Linear drainage with a load-rated steel lid — specified wherever surface water has to disappear without giving up the surface to traffic.
Loading bays & forecourts
D400-class crossings in front of dock doors, where HGV wheels stand and turn.
Yard perimeters & aprons
Long straight runs collecting yard wash-down and rain before it reaches the gate.
Kerb lines & crossings
Channel runs along kerbs and across entrances, classed for the traffic that uses them.
Washdown & corrosive zones
Same module in SS304 / SS316 for food and chemical washdown areas.

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. Modules 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
EN 124 load classes, referenced
Classes A15 to D400 are referenced for selection; covers are produced to the class you specify, with joint and weld checks on our five-stage QC plan.
ASTM A123 / ISO 1461 HDG
Galvanized coating thickness checked by sampling on every galvanized batch before covers are released — outdoor and civil runs ship protected.
CE & SGS tested
Certified & tested, reports on request — batch-tested covers with documents you can verify, not a certificate wall.

FAQ
Frequently Asked Questions
Do you supply the channel and the grating as one matched package?
Grating covers, frames and banding are made in our own workshop; channel bodies, end caps and outlet fittings are quoted as companion items alongside the panels. Everything arrives as one matched module set, listed line by line in your itemized quote.
How do I plan coverage and outlets for my run?
Send the run length, channel width and outlet positions — a hand sketch is enough. We confirm module count, end caps and outlet placement in the free drawing review, included in the 24-hour quote.
What lead time should I plan for?
Samples ship in 5–7 working days and mass production runs 15–25 working days after drawing confirmation, both including hot-dip galvanizing. Shipped worldwide FOB Tianjin — EXW or CIF negotiable.
