JAS certification - Stable supply of flat square and non-standard structural materials with a height of 300mm or more.
With our timber procurement capabilities, we can stably supply large cross-section and long-length materials that other companies find challenging! We produce high-quality structural materials at our JAS-certified factory.
I want to use square beams with a height of over 300mm in a large-span hall, but I gave up on adoption due to unstable procurement. I am also worried about whether the long materials specified in the drawings can be reliably obtained since the wood shock. Do you have such concerns? Our company resolves this 'procurement anxiety' by consistently handling everything from direct purchasing in the log market to sawing, drying, and processing. Our strengths lie in our unique procurement network and our own JAS-certified factory. This allows us to supply non-standard structural materials, such as square beams over 300mm in height and long materials, in a planned and stable manner, even if they are generally difficult to distribute. In particular, in spatial designs that require large spans, such as common areas in medium-sized wooden buildings like community centers, our 'procurement capability' and 'processing technology' are utilized. We deliver JAS-certified structural materials with guaranteed quality, in the necessary quantities, at the right time.
