Pine timber that is graded as S5 and S7 complies with certain stress grades, which relate to specific load bearing strengths as per the SANS (SABS/SATAS) certification. Foresta Drum Manufacturing has permission to use the SATAS (South African Technical Auditing Services) logo on its solid and finger-jointed structural pine timber.
As the name suggests, structural timber has a wide variety of applications - including the construction of roof trusses and frames for timber homes, cabins, sheds, stages and decking bases.
Because of its application, strucural grade timber has minimal allowance for defects such as warping and knots. It is available in a wide variety of sizes and lengths that cater for specific applications and requirements.
