Curved Beams
Description

Curved glulam timber beams have long been a cost-effective form of construction, both for their strength and design capabilities. As well as being aesthetically pleasing, the characteristics of timber enable glulam beams to be formed to most shapes and sizes. Curved timber can be formed in almost any shape drawn, from elliptical beams and tapering curves that change in radius, to beams that transition from a straight line into a curve.

Techlam is able to form any radius of curvature in timber, from 100mm to 100m.

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.
