Factories

We have our own three factories of prestressed and precast concrete products in Japan. All our factories are registered under JIS and approved ISO9001 as well as ISO14001. The production is processed with the reliable equipment and facilities in the factories under strict quality control. The production equipment is the most advanced and environment-friendly production oriented. The factories are thus equipped with automatic steam curing systems and concrete disposal recycle systems. The products are constantly of high quality and performance.
