Tonusa believes that product testing is necessary due diligence to ensure the integrity of our high quality standard. Throughout our history of designing, manufacturing, importing and distributing cabinetry and lifestyle products for the hundreds of thousands of homes and properties, we have been testing against established U.S. and international standards such as ANSI and ASTM for quality and materials compliance. Our process of testing begins at the source with our materials. From wood testing to hardware durability testing, stress tests, etc., we understand that the quality of products can only be as good as the materials we use to build them. Our factory has a self-contained testing lab which is fully equipped with state of the art testing equipment and certified to meet the strictest standards. We also engaged one of the U.S.’s most respected wood testing laboratories, the Washington State University Wood Materials and Engineering Lab (WSU-WMEL) to conduct a wood integrity test to ensure our engineered wood materials surpass existing standards for such material. The results showed it not only exceeded the standard, it even performed better in tests against other solid wood samples.
