Our commitment to product excellence is reflected in our rigorous quality control measures, which commence with the selection of top-notch oak. Before any timber is incorporated into our manufacturing process, our skilled team of carpenters and timber graders meticulously inspects and grades each piece. This meticulous process guarantees that the wood meets our stringent standards for fresh green oak beams, ensuring a consistently strong, durable, and aesthetically pleasing final structure.
