Pedestrian trench covers
Light sections for walkways, parks and building surroundings where only foot traffic applies.
Engineered Around Your Load & Span
Trench Cover Grating
Trench cover grating closes drainage channels and utility trenches with an open grid that admits surface water while carrying foot or vehicle traffic. From pedestrian walkways to heavy truck crossings, every cover is sized for its clear span and load — with banding, frames, hinges and locking options for safe inspection access.
- Pedestrian through heavy vehicle load classes
- High open area for drainage flow
- Angle / channel frames, hinged and lockable options
- Sized to clear span, load and support conditions

What is trench cover grating?
Trench cover grating spans drainage channels and utility trenches with an open grid that admits surface water while supporting foot or vehicle traffic. Covers are typically banded on all sides for edge stiffness and safe handling, and seat on embedded angle or channel frames.
Correct specification starts with the clear trench span and the traffic above: pedestrian covers use light sections, while driveway crossings need heavy-duty bars confirmed against wheel load, contact area, span and support conditions before quotation.
Hinged, lockable and lifting-key designs keep inspection and cleaning access practical without loose covers — tell us the opening size and access frequency and we will detail the arrangement.

Fabrication & Quality Notes
- Covers are banded on all four sides; vehicle-rated covers receive load banding matched to the wheel path.
- Frames, anchors and hinges are fabricated as matched sets with the covers and checked before finishing.
- Cover width and seat depth are verified against the clear trench span so covers seat without rocking.
- Load class is confirmed against clear span, wheel load and support conditions before production.
Packaging
Packaging & Delivery
- Covers stacked with spacers and strapped; frames bundled separately with matching tags.
- Each cover tagged by trench zone or chainage to match site installation sequence.
- Galvanized covers ventilated in packing to reduce wet-storage staining during sea freight.
FAQ
Trench Cover Grating FAQs
Can trench covers carry trucks?
Yes — heavy-duty covers are engineered for vehicle crossings. Provide clear span, wheel load and traffic frequency and we will confirm the specification before quoting.
Do you supply the frames too?
Yes. Angle or channel frames can be supplied with the covers, including anchors for concrete embedment, or covers can be made to suit your existing frames.
Can covers be hinged for cleaning access?
Hinged and lockable designs are available for trenches needing regular inspection. Tell us the opening size and access frequency.
What information is needed to quote trench covers?
Clear trench span, cover width and length, traffic type (pedestrian, forklift or truck with wheel load), frame requirement and finish. A sketch or layout drawing lets us detail the full set.
Are the covers banded?
Yes — covers are banded on all sides as standard for stiffness and safe handling; vehicle-rated covers get load banding designed for the wheel path.
Can you match covers to existing frames?
Yes. Measure the frame seat width and depth and the clear opening, and we will make covers that seat correctly in your existing frames.
What MOQ and lead time apply to matched trench-cover sets?
Standard drainage covers start around 10–20 m²; custom and vehicle-rated sets around 50 m². Typical lead time is 15–25 days including galvanizing; samples take 3–7 days.
