Product Information

Full details

The Snowdon Timber 6x2 treated beams are designed for homeowners, DIY enthusiasts, and contractors who need reliable structural support for outdoor landscaping, decking, and fencing projects. These beams offer excellent durability through pressure treatment, which guards against rot and moisture, providing a solid foundation for weight-bearing tasks. However, users should note that as natural softwood, these boards require regular maintenance and sealing over time to preserve their structural integrity and appearance against extreme weather conditions.

FAQs

Can these beams be used indoors?

While they are safe for outdoor use, the pressure treatment chemicals may have a distinct odor, so they are generally recommended for exterior applications only.

Do I need to treat the wood after buying it?

The timber is already pressure-treated against rot. However, applying a water-repellent stain will help preserve the appearance and prevent splitting.

What does C16 grade mean?

C16 is a structural grading standard for softwood that ensures the timber meets specific strength and stiffness requirements for construction projects.

Can I use these for ground contact?

Yes, the pressure treatment is rated for external use, though placing them on a gravel base or concrete pads is recommended to keep them out of standing water.

Are these beams planed or rough-sawn?

These beams are planed on all sides for a smooth, consistent finish that is much safer to handle than rough-sawn lumber.

Troubleshooting

Timber showing surface splits or cracks

Small checks are common in softwood as it dries. Apply an exterior wood filler if the structural integrity is compromised or paint/stain to seal the gap.

Wood appears green or discolored

This is a normal result of the pressure treatment process. The color will fade to a natural grey over time, or you can paint over it with an opaque wood stain.

Beam appears warped or twisted

Natural timber reacts to humidity. Store boards flat on level ground, supported by spacers to allow airflow until ready for immediate installation.

Pros and Cons

Pros

  • Resistant to rot and decay due to pressure treatment
  • Planed surface provides a safer and cleaner aesthetic
  • C16 structural grading ensures predictable performance
  • Easy to cut and maneuver for custom DIY projects

Cons

  • Softwood material is prone to natural movement like warping
  • Requires professional sealing to maintain long-term outdoor protection
  • Limited to 1800mm lengths, which may require joining for larger spans

Setup, Compatibility & Care

Installation requires standard carpentry tools, including a circular saw or handsaw, a level, and appropriate weather-treated exterior screws or joist hangers.

  1. Planning: Calculate the span requirements for your load-bearing structure, as C16 timber has specific deflection limits.
  2. Cutting: Always seal cut edges with a proprietary wood treatment to prevent moisture ingress.
  3. Mounting: Use galvanized or stainless steel hardware to prevent corrosion when in contact with the pressure-treated chemicals in the wood.
  4. Maintenance: Although pressure-treated, we recommend applying an exterior wood stain or oil annually to prevent checking and to keep the timber looking fresh.
