Business Areas

• High-performance coated steel pipe: The company primarily produces composite steel pipes with polyethylene coated on the outside of carbon steel pipes and an antibacterial zeolite resin layer formed on the inner surface. These products are supplied to the water and sewage pipe and industrial piping markets based on their excellent pressure resistance, corrosion resistance, and chemical resistance.
• Double-insulated pipe: We produce double-insulated pipes for district heating, double-insulated pipes for water and sewage, and double-insulated pipes for freeze prevention. Straight pipes and various fittings are pre-insulated at the factory, contributing to reduced construction time and maintenance costs.
• Stainless steel coated steel pipe and other steel pipes: We handle various types of steel pipes and fittings, including stainless steel coated steel pipes. We provide custom-made products according to special applications and design conditions, supplying core materials necessary for various infrastructure construction projects.

Products

• Composite steel pipe: This is a double-structured product with polyethylene coated on the outside of a carbon steel pipe and an antibacterial zeolite resin layer formed on the inside. It has excellent pressure resistance, corrosion resistance, and chemical resistance, and is a new concept pipe that is hygienic and suitable for water supply.
• Double-insulated pipe: It consists of an inner pipe through which the conveyed substance passes, insulation material, and an outer pipe that protects the insulation material. It is made of straight connection pipes and fittings such as bends, tees, and reducers for branching and distribution, and is used for district heating and water/sewage.
• PE coated steel pipe: Extruded polyethylene coated steel pipe (KS D3589), etc., with an HDPE exterior that perfectly blocks moisture and air. It prevents corrosion of the inner pipe and changes in insulation material, ensuring long-term durability and stability.

Special Notes

• Proprietary coating and fusion technology: Since its establishment in 2016, the company has been producing high-quality steel pipe products based on its proprietary coating and fusion technology. It holds numerous patents, thereby securing a differentiated competitive advantage in related fields.
• Designation as an Excellent Product by the Public Procurement Service and Quality Certification: The 'Double-structured polyethylene composite steel pipe with high-temperature and high-pressure fusion technology' was designated as an excellent public procurement product by the Public Procurement Service in 2024. Furthermore, it produces high-quality products based on ISO9001/14001 quality management systems and Korean Industrial Standards (KS) certification.
• Development of eco-friendly products and awards: The company is also focusing on developing eco-friendly buoys to solve marine environmental pollution problems, creating sustainable value. It was recognized for its efforts in environmental conservation by receiving the Minister of Environment Award at the Korea Environment & Energy Awards.

Recruitment Information

• Main Hiring Positions: We mainly recruit for production positions (double-insulated pipe manufacturing assistant, pipe manufacturing related, PE coating team), and also recruit for quality control managers and office workers (production management, material management).
• Benefits: We offer benefits such as enrollment in four major insurances, severance pay, provision of lunch, 5-day work week, annual and half-day leave system, separate payment for overtime/extended/holiday work allowances, separate payment for production incentive allowance, and provision of work clothes and safety shoes.
