Single covers & frames
For manholes, pump, valve and transformer chambers, cable draw pits, lighting and fuel pits, hydrant pits and plant access chambers.
Products
The Gatic range of access covers & gratings
Five load classes, every major format — machined ductile iron, gas- and air-tight when correctly installed, engineered to sit flush and non-rocking under traffic.
Cover options
Recessed for infill, or solid top
Every format is available in two surface styles, so the finished installation matches its surroundings.
Recessed
Concrete or paviour infill
Cross-ribbed recesses take a concrete infill (specified to 45 N/mm² cube strength) or brick paviours, giving a hard-wearing surface that matches the surrounding paving — with the anti-slip character of the pavement around it.
Solid top
Anti-slip lozenge pattern
Solid top covers are lighter than infill units and carry a raised lozenge anti-slip pattern. Best suited to non-high-density traffic locations; assist-lift versions make single-person opening safe and easy.
Formats
Five formats, one machined system
Modular components share common frames, seating faces and lifting keys across the range — so covers are easy to remove, replace and extend.
Duct covers & frames
Modular runs over pipe and cable service trenches — the standard for utilities and data centre distribution corridors.
Continuous trench covers
Linked cover runs along service trenches, sealed and non-rocking under carriageway and dock traffic.
Single gratings & frames
Gully tops and channel gratings for kerbside and yard drainage, matched to the C250 to F900 duty of the surrounding pavement.
Continuous gratings & frames
Linear grating runs for channel drainage across aprons, yards and carriageways.
Multispan covers & frames
Wide chambers covered by multi-part units with removable structural steel beams — the format used on airport aprons and container terminals.
Loading groups
Choose the class, not more cover than you need
The right load class matches the duty the project needs at the best strength-to-cost ratio. We help you make that selection — and regard it as an important part of our service.

| Class | Test load | Wheel load* | Typical applications |
|---|---|---|---|
| B125 | 125 kN | 3 t | Footways, pedestrian areas, car parks, driveways, internal floors |
| C250 | 250 kN | 5 t | Kerbside installation, pedestrian precincts, yards |
| D400 | 400 kN | 11.5 t | Carriageways, hard shoulders, parking for all vehicle types, power stations |
| E600 | 600 kN | 20 t | Dockyards and other areas with slow-moving wheel loads up to 20 tonnes |
| F900 | 900 kN | 35 t | Airfield pavements, taxiways, civil airports, dockyards |
Classes and test loads per BS EN 124; compliance does not replace the user's responsibility to ensure correct installation. *Wheel loads are manufacturer's guidance from Gatic literature — single, slow-moving wheel loads. In high-density traffic conditions, a factory-fitted vibration-resistant locking system is recommended. Full specifications: www.gatic.com.
Features & benefits
What a machined cover buys you
- Fine tolerances — seating faces machined for metal-to-metal contact within 0.25 mm
- Gas, air & watertight — graphite grease film seals the joint against ingress when correctly installed, under normal rainwater conditions
- Pressure-tight options — locking screws and holding-down bolts to resist upward pressure
- Easy removal & replacement — machined undersides slide covers out without lifting damage
- Operator control — jack-screw lifting keys locate positively to break the seal safely
- Closed keyways — plastic plugs keep keyways clear of debris
- Ventilation — up to four 25 mm ventilation tubes in recessed covers
- Materials — ductile iron to BS EN 1563, structural steel to BS EN 10365
Specialist & bespoke
When the standard range isn't the answer
Most requirements are met by the standard range. When they aren't, Gatic's design engineers develop bespoke solutions — and 90-plus years of experience usually means the challenge has been met before.
Specialist additions
- Assist lift — single-person operation for recessed and solid top covers
- Hinged hydrant covers — access to valves and hydrants without removing the whole cover
- Solid top circular covers — for circular chambers and duct entries
- Gatic PAVE — paviour-infill covers for heritage and pedestrian surfaces
- Bespoke products & solutions — engineered to project specifications
