S-TECH was established in 1989 as a manufacturer specializing in valves and parts for short air blasting equipment. Since then, it has been developing and supplying more convenient products that were previously entirely dependent on imports. We collaborate with numerous companies, including Hyundai Heavy Industries, Hyundai Mipo Dockyard, Hyundai Samho Heavy Industries, Hanwha Ocean, Samsung Heavy Industries, K Shipbuilding, Doosan Energy, and HSD Engine, among others. We continuously research and strive to provide better products, holding multiple patents and utility models. We will continue to strive to become a company that grows alongside our customers by supplying high-quality products with superior technology.
