Started in March 1998 as a company that produces high-thermal resistant fabrics based on glass fiber weaving technology, Large Co., Ltd. started the development of insulators for automobile exhaust systems in 1999, playing an important role in the automobile industry through continuous product development and quality improvement, including sound absorption, noise insulators, and strength reinforcement.
 Starting to develop thermoplastic composite materials, which are the main materials for future industries in 2007, we completed the development of the world's first multi-layered continuous fiber thermoplastic composite materials in 2010. Today, we are reborn as a specialized company that produces and supplies composite materials, new materials which are lightweight, strong, eco-friendly, and recyclable.
 We will become a "company that fulfills its social responsibilities" where everyone can be happy by studying and developing eco-friendly material parts so that future generations can live in a better environment. We ask for your continuous interest and support.
