SDC – other models: the collective page of curtainsider semi-trailers outside the named ranges, tandem- and triaxle versions, 5,600 to 23,220 kg unladen weight, 30,000 to 45,000 kg gross weight
This page gathers the SDC semi-trailers the register could not assign to a named range. SDC Trailers, based in Northern Ireland, is one of the large semi-trailer makers on the British Isles, known above all for curtainsider versions; the model range carries designations such as TANDEM AXLE CURTAINSIDER and TRIAXLE C/SIDER for these, alongside the abbreviation types SDCCS, SDCPL45B3, SDCTL45B3 and TL45B3 and the shorter codes SK40B3 and SK42.

The register lists here 16 versions with unladen weights from 5,600 to 23,220 kg, gross weights from 30,000 to 45,000 kg, lengths from 10,800 to 16,280 mm and widths from 2,500 to 3,000 mm.
Curtainsider semi-trailers are the standard type of European general-cargo haulage because they can be loaded from the side and so work at ramps without a rear opening; SDC thereby supplies mainly the British and Irish market and hauliers using the ferry routes across the Irish Sea.
As class O4 semi-trailers, SDC curtainsiders need an air brake system and driving licence category CE for towing. The tandem- and triaxle versions differ in axle-load distribution: the three-axle version spreads the load more evenly and allows a higher gross weight, while the tandem-axle version offers slightly more payload at a lower unladen weight.
On a used example, the condition of the tarpaulin and sliding-curtain rails, stanchions and roof bows, axles and braking system under high payload, rust on the frame, and the condition of the kingpin and fifth-wheel plate count; spare parts run through the SDC service network and the general market for semi-trailer accessories.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
