Full-scale production line of the cylindrical Laminated Veneer Lumber (LVL) that was designed and set up in a factory of Watanabe Jigyosho Co. Ltd. In 2000, started to trial manufacture of structural or non structural posts using cedar, larch and pine veneers for the domestic new buildings Through this trial use, the success of practical applications of the cylindrical LVL was verified. The posts used were as follows :1) Two main posts of the entrance hall in Teijo kindergarten in NoshiroOuter diameter : 800mmφ, thickness of wall : 80mm, height : 6,300mm and 2,600mm2) Six columns along the front corridor in the Cultural Exchange Center in Yuri-town, AkitaOuter diameter : 600mmφ, thickness of wall : 47mm, height : 1,500mm3) Twenty-four decorative posts set outside of the Multi-purpose huge building in Kyowa-town, AkitaOuter diameter : 750mmφ, thickness of wall : 46mm, height : 5,500mm or 5,170mm4) Two Cabinets for Local Information at Michi-No-Eki of Yadate Ridge and Futatui, AkitaOuter diameter : 700mmφ, thickness of wal l: 45mm, height : 1,900mmThe costs of these products were analyzed and the production was assessed to be profitable.

2000年在渡边实业的工厂设计并建立了圆柱形单板层积材（LVL）的全规模生产线，开始试制用于国内新建筑的雪松、落叶松和松木单板的结构或非结构支柱。通过这次试用，验证了圆柱形LVL实际应用的成功。使用的柱子如下：1）位于野四郎的Teijo幼儿园入口大厅的两个主要柱子外径：φ 800 mm，壁厚：80 mm，高度：6，300 mm和2，600 mm 2）位于秋田由里町的文化交流中心的前廊上的六根柱子沿着外径：φ 600 mm，壁厚：47 mm，高度：1，500mm3）秋田京和町多功能大楼外设置的24根装饰柱外径φ 750mm，壁厚46mm，高度：5，500mm或5，170mm 4）秋田县八手岭和二台町的町之站的地方信息室2个外径：φ 700mm，壁厚：45mm，高：对这些产品的成本进行了分析，并评估生产是有利可图的。
