Strength grading for structural timber

‍Structural timber refers to spruce or pine timber that is used for load-bearing structures or part of such a structure and for which there are set minimum strength and elasticity requirements.

‍Principle
‍
‍Structural timber is graded either visually or by machine. Visual grading requires sufficient expertise from the person carrying out the grading. Usually, this means training in grading course and passing examination.
Machine strength grading is based on mechanical measurements of the timber’s density and knots.

At Lotus Timber, we offer a comprehensive range of strength classes tailored to meet market demands.

Why Choose Construction Timber?

‍Construction timber is specifically evaluated for its mechanical properties, ensuring consistent performance in structural applications. Developers, retailers, and manufacturers select Lotus Timber’s premium construction timber, which is derived from our slowly grown, biodiverse forests. Our diverse product range caters to commercial, residential, educational, and industrial projects.

‍C14 to C30: These classes are suitable for various structural applications, allowing builders to select the perfect timber based on strength requirements without compromising on weight or design flexibility.
‍TR26: Specifically manufactured for high load-bearing requirements, TR26 timber is ideal for applications where additional strength is paramount.

The benefits of using strength-graded timber include:

‍Enhanced Structural Integrity: With precise grading, every piece of timber has been assessed for its strength, allowing for the optimal use of material based on load requirements. This reduces the risk of structural failure and enhances the overall longevity of buildings and products.
‍Sustainability: All our wood supply chains are covered by a wood traceability system that is third-party verified according to PEFC, FSC® and are CE marked as they meet all European health, safety, and environmental protection standards. We ensure that the forests we harvest are duly regenerated.
‍Consistency in Quality: Each timber piece is calibrated to meet strict dimensions, providing uniformity across your project. This precision reduces waste and ensures ease of handling and construction, ultimately saving time and costs.
‍Versatility: Whether for residential homes, commercial buildings, or industrial applications, strength-graded timber products are adaptable to a wide range of uses. Their robustness accommodates various construction methods, making them ideal for framing, flooring, roofing, and more.
