Pressure Treated 4×1 Timber

Our 4×1 timber (100mm x 22mm finished size) is a versatile, rough sawn, pressure-treated board designed for long-lasting outdoor use. Made from quality softwood and treated to resist rot and fungal decay, it’s a reliable choice for fencing, cladding, and a wide range of exterior projects.

The rough sawn finish gives this 4×1 timber a natural, rustic appearance that’s ideal for traditional garden builds. It’s especially popular for hit and miss fencing and Yorkshire boarding, where character and durability are just as important as strength. The pressure treatment allows the timber to perform well in changing weather conditions, making it suitable for ground-level and exposed applications.

Whether you’re building privacy screens, decorative cladding, or garden structures, this timber offers dependable performance and excellent value. Any cut ends should be sealed with an End Seal Preservative to maintain treatment performance.
