Company information
<We provide nationwide support> LNS JAPAN Co., Ltd. is an engineering company that performs maintenance and repairs of equipment and metal structures in various industries (such as petroleum, chemicals, power generation facilities, ships, heavy machinery, automobiles, steelmaking, etc.) using the METAL STITCHING method. Currently, most of the critical equipment used across industries is facing a challenging situation for new capital investment due to the global economic downturn. In Japan's industries, welding technology, which is widely used for metal repairs, has recently led to significant damage to many pieces of equipment and critical assets due to a shortage of skilled craftsmen and inexperienced welding repairs, with many cases worsening. Our company is the only certified company in Japan and is committed to continuous technological development in collaboration with our parent company, LOCK-N-STITCH INC, which continues to leap and grow as a global enterprise. We promise to ensure thoroughness for extending the life of equipment and providing high-quality and rapid maintenance by avoiding issues such as deformation from heat and secondary cracking, which have been problems with traditional welding repairs, while also achieving shorter construction periods and lower repair costs. For repairs where you want to avoid using fire or where time is limited, please contact LNS JAPAN.
