Grades & Finishes

Engineered Glulam Landscaping Posts
Visual - Tight Knot Appearance

This grade is intended for use in applications where appearance of the member is important and clear or painted finishes are used. All surface voids are filled, small tight knots are permitted. The surfaces are planer machined to a high quality finish.
Specifications: 90% of the post is clear timber, there may be up to 10% that has a small tight knot, of up to 19mm.

Prolam glulam timber beams can be used in any form of construction where the structure relies on AS/NZS 1170: 2002 and NZ 3603 1993. The design can be from the Prolam online software, span tables or specific design by an engineer using Prolam’s structural properties. All glulam timber products must be stored, handled and installed in accordance with all Prolam’s installation requirements. Prolam glulam works well in harsh environments, for example in corrosive chemical stores, fell-monger, acid plants, salt-water environments and swimming pools, as it does not rust and the glues used are service class 3 certified.


Limitations on use

This laminated treated product must be protected from the elements until it is sealed, Prolam Landscaping Posts can be supplied with a temporary sealer if required. Timber naturally absorbs moisture from the surrounding environment. This can cause the product to alter dimensionally. All exposed timber must be sealed with a good quality paint or stain system within 14 days of delivery to dramatically reduce the incidence of dimensional change and increase longevity. All cuts, holes and rebates must also be sealed to prevent the ingress of moisture.

Prolam glulam products can be used in specific fire performance situations, and must be designed in conjunction with a fire engineer.
