• Dimensional stability with minimal twisting, warping or splitting compared with solid sawn posts, which matters where posts are installed ahead of handrails, infill or cladding.
• PL12 bracing unit contribution allows fewer posts and greater spacing, opening up sightlines in pergola, veranda and alfresco applications.
• Visual grade appearance suitable for exposed feature applications.
• Direct in-ground installation removes the need for post brackets and the associated detail.

Ideal for gate posts, fence posts, supporting trellis, pergolas, fences, decks, and carports.

• Available in sizes 88mmx88mm to 300mmx300mm
• PL8 and PL12 strengths
• Available in four finishes: Sanded, Pre-Primed, Sanded & Sealed, Bandsawn

PL8 and PL12 posts are not interchangeable. PL12 is manufactured from SG12 timber and provides higher strength, stiffness and bracing units. Substituting PL8 for PL12 will not deliver the specified structural or bracing performance. PL is the Prolam prefix and GL is the generic glulam prefix; where PL is specified, no substitution should take place.

Posts must be sized in accordance with NZS 3604, the Prolam Specifier, Prolam span tables, or by an engineer using Prolam published structural properties. No drilling, notching or rebating unless specifically detailed by the design engineer.

Timber must be protected from the elements until sealed and sealed with a quality paint or stain system within 14 days of delivery, with all cuts, holes and rebates resealed. This is critical for in-ground posts where the cut end sits below ground.

Fixings and connectors must be selected for the corrosion environment in accordance with NZS 3604 Section 4.

CodeMark certification applies to Prolam H5 posts specifically and does not extend to other Prolam products.

For non-structural landscape applications, specify Prolam Landscaping Posts.
