Decking boards 38mm x 150mm (finished 32mm x 145mm) are a reliable choice for outdoor timber decking projects across the UK. Designed for garden decks, patios, and raised platforms, these boards offer a robust finished thickness that handles foot traffic and weathering well in the South Wales climate.
Specifications
| Property | Detail |
|---|---|
| Material | Softwood timber |
| Nominal Size | 38mm x 150mm |
| Finished Size | 32mm x 145mm |
| Length(s) | 3.6m (12ft), 4.8m (16ft) |
| Profile | Decking board (flat face) |
| Use Class | Exterior / UC3 |
What it's used for
- Garden decking and patio deck surfaces for domestic properties
- Raised decking platforms and walkways in landscaped gardens
- Poolside or hot tub surrounds where a durable outdoor board is required
- Commercial outdoor seating areas and public realm decking projects
Fitting and handling
Before fixing, store boards flat and off the ground in a covered, ventilated area for at least 48 hours to allow them to acclimatise to site conditions, particularly important in the variable Welsh climate. Fix boards using stainless steel or hot-dip galvanised decking screws at each joist crossing, leaving a 5-6mm expansion gap between boards to allow for moisture movement. Once laid, apply a good-quality exterior decking oil or preservative stain to all exposed surfaces and end grain to extend service life.
FAQ
What is the difference between the nominal size and the finished size?
The nominal size of 38mm x 150mm is the rough sawn measurement before the board is machined and profiled. The finished size of 32mm x 145mm is what you actually receive after planing and processing, which is the measurement to use when planning your project.
Do these decking boards come pre-treated?
These boards are not listed with a factory preservative treatment, so we recommend applying a suitable exterior preservative, decking oil, or stain shortly after laying, paying particular attention to end grain cuts made on site. This will protect the timber and maintain its appearance over time.
What length should I order for a standard garden deck?
The 3.6m length suits most standard garden deck widths and produces less waste on smaller projects. The 4.8m board is better suited to larger or longer runs where fewer joints are desirable. Measure your joist span carefully and add a small allowance for trimming before ordering.
