Business sectors

• Shipbuilding/Offshore Plant Business: We focus on producing special bolts requiring extreme precision and durability, such as hydraulic coupling bolts and holding-down bolts that connect ship engines and propeller shafts. In particular, we have successfully developed high-strength bolts capable of withstanding fastening pressures of over 700 bar, thereby localizing key components that were previously dependent on imports.
• Power Generation/Nuclear/Wind Industry: We supply mechanical parts and precision machined products used in power plants and the nuclear industry, and also produce special metal bolts and nuts for the wind power industry. This contributes to the technological self-reliance of the domestic energy industry.
• General Industry and Defense: We specialize in manufacturing bolts, screws, machine parts, and precision machined products required for various industrial sectors, including construction bolts, plant bolts, and engine and defense components. We provide customized products that meet the specific situations and needs of our customers.

Products

• Special Bolts and Nuts: We develop and produce special-purpose bolts and nuts designed to withstand high pressure or achieve lightweighting, such as coupling bolts, holding-down bolts, and aluminum alloy bolts for shipbuilding and marine applications. This contributes to the localization of high-value-added fastener components.
• Industrial Bolts and Screws: We manufacture various types of bolts and screws, including hex bolts, stud bolts, U-bolts, and anchor bolts, used across the construction, plant, and power generation industries. We supply highly reliable products through strict quality control.
• Precision Machined Parts: In addition to bolts and nuts, we produce machine parts and precision machined parts to provide customized products tailored to customer needs. Based on our precise machining technology, we manufacture components applicable to various industrial fields.

Special Features

• Unrivaled Technological Capabilities and R&D: We have demonstrated unrivaled technological capabilities by successfully carrying out government R&D projects, such as the development of 'shipbuilding and marine coupling bolts' capable of withstanding high pressures exceeding 700 bar and 'aluminum alloy bolts' for lightweighting. We are expanding our technology portfolio through continuous investment in research and development.
• Quality and Production Efficiency: We possess the capability to produce high-quality products by obtaining numerous quality, environment, and safety certifications, including ISO 9001, ISO 14001, ISO 45001, KEPIC MN, and SN. We are maximizing production efficiency by implementing a smart factory system.
• Supply to Diverse Industries: We have established ourselves as a highly reliable partner by supplying core components to major domestic and international heavy industry and construction companies, including Daewoo Shipbuilding & Marine Engineering and Hyundai Mipo Dockyard. This contributes to securing a competitive advantage in domestic and international markets.

Job Information

• Main Recruitment Positions: We are primarily hiring for roles such as general administration and accounting, CNC lathe operation and production processing, sales office staff (quoting, supplier management), mechanical engineering technicians, and researchers.
• Benefits: We operate various welfare systems, including lunch and dinner provision, housing fund support, bonus payment after one year, and social insurance enrollment.
