Structural Laminated Posts by Techlam NZ

Structural Laminated Posts

Description

Laminated posts are an effective solution to problems that can arise from using solid timber products. The manufacturing process ensures that a dry laminated post will stay straight and true, eliminating twisting and cracking often found in solid timber products.

All Techlam posts are supplied coated with a temporary water-based sealer to protect the posts during the construction period.

Scope of Use

Techlam laminated timber posts and beams can be used in all forms of construction where the structure relies on AS/NZS 1170: 2002. The design and use must be in accordance with Techlam specifications, design criteria and selection tables.

Limitations on Use

Techlam glulam products are supplied with one coat of temporary sealer applied. To preserve the aesthetics of the product, it should be further sealed with a high quality primer and two full coats of premium enamel or acrylic topcoat within 14 days.

All cuts and notches, holes and rebates must be sealed with protective coating to prevent shrinkage and swelling. All exterior timber products must be kept dry and protected from excessive heat, direct sunlight or prolonged exposure to the elements. Where specific fire performance is required Techlam laminated timber posts and beams must be designed in conjunction with a fire consultant.
