Since the foundation in 2016, GM is a company specializing in aluminum windows and curtain walls that always seeks newness and changes.
We are committed to product development to respond quickly to changing environments and energy-saving measures, and to meet
the growing needs of consumers. As a result, I obtained KS certification and patent. In addition, new products are always under development by establishing a research institute affiliated with companies.
GM will continue to make efforts to fully realize all systems from design to manufacturing to construction to quality assurance. We will
reflect all your requirements and repay you with the best quality and products.
