SRT Products
SRT (Structural Round Timber) products can be priced and delivered as turnkey structural systems, custom-designed configurations, and decorative components from round timber. Trees are purchased from sustainably managed forests, prioritizing small diameter, low commercial value, and otherwise waste-stream trees. Unlike most other forest products, SRT sources trees for their natural form and strength for long-lasting biophilic components. This unmilled timber can be up to 50% stronger than milled lumber of the same size. SRT products include columns, beams, and truss assemblies for cost-competitive, low embodied carbon alternatives to steel, concrete, or laminated wood products. All products are peeled, sanded, pre-fabricated, finished, and delivered to site with pre-fit steel connection hardware, PE stamped shop drawings, and easy installation guidelines.
SRT fabricators have standardized production processes, installation packages, and warranties that limit risk for general contractors and make decision-making easy for designers, engineers, and owners because to their ease of integration with other building materials, LEED and LBC building standard credits, and unmatched aesthetic appeal.
