Popular North American design for contemporary deck railing

Clear grade Western Red Cedar cap rail planed smooth on 4 surfaces with eased edges.

A popular method of constructing deck railing in North America is to attach 40 x 90mm Top/Lower Rails between square newel posts and run a 40 x 140mm Cap Rail across the top of the posts. Square Balusters are attached to the Top/Lower Rails. The top of the baluster butts up to the underside of the Cap Rail and bottom of the balusters can be cut at 45º to give a more finished look.

Finishing & Protection

It is recommended that a finish is applied to all surfaces, including ends, before installation. The type of coating will be determined by the final finish and appearance desired.

Why Pre-finish?

  • Enhances the natural beauty of wood
  • Ensures a consistent finish
  • Applied in factory conditions
  • Long lasting protection against weathering
  • Simple maintenance routine
  • Reduces onsite labour costs

What is weathering?

There is a risk involved when leaving wood exposed to the elements. During the weathering process wood can appear unsightly as the material can blacken due to moisture getting into the fibres and pulling out tannins and extractives. Finish protects the wood from moisture absorption and UV degradation.

Western Red Cedar is the ultimate green building material. It is legally, responsibly and sustainably harvested in the publicly managed forests of British Columbia, Canada. Less than 1% of standing timber is harvested each year.

For each tree harvested, three are replanted to ensure the forests will exist in perpetuity. Western Red Cedar has a low impact on the environment throughout its life cycle. It requires significantly less energy to produce than man-made alternatives and is bio-degradable.
