<We provide nationwide support> LNS JAPAN Co., Ltd. is an engineering company that performs maintenance and repairs on cracks and damages in equipment and metal structures across various industries (such as petroleum, chemicals, power generation facilities, ships, heavy equipment, automobiles, steelmaking, etc.) using the METAL STITCHING method. Currently, most of the critical equipment used across industries is facing a tough situation regarding 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 that our repairs do not cause deformation or secondary cracks due to heat, which have been issues with traditional welding repairs, while also shortening construction periods and reducing costs, thereby extending the life of equipment and ensuring high quality and prompt maintenance. For repairs where fire is not desired or where time is limited, please contact LNS JAPAN.
