Korea Polytech Co., Ltd. is a civil engineering and piping material manufacturing company located in Buron-myeon, Wonju-si, Gangwon-do. We specialize in the development and production of high-functionality sewage pipe materials, including Glass Fiber Reinforced Plastic (GRP) pipes, polymer concrete manholes, and integrated pump station manholes. Based on our patents and excellent procurement product certifications, we supply high-quality piping structures to local governments and public construction sites nationwide.

Business Areas

• Manufacturing of Glass Fiber Reinforced Plastic Piping Materials: We manufacture lightweight, high-strength Glass Fiber Reinforced Plastic (GRP) pipes and fittings used in water/sewage and various civil engineering sites. They are applied to various transport conduits due to their excellent corrosion resistance and durability.
• Production of Composite Material Manhole and Pump Station Systems: We produce polymer concrete manholes resistant to hydrogen sulfide and chemicals, as well as GRP integrated manhole pump stations. We extend the lifespan of civil engineering structures by applying centrifugal methods and high-strength composite molding technology.

Products

• Glass Fiber Reinforced Plastic Pipe (GRP Pipe): Piping manufactured by combining glass fiber and resin; it is widely used for sewage pipes and agricultural water conduits due to its excellent corrosion resistance and watertightness.
• Polymer Concrete Manhole and GRP Pump Station Manhole: Manhole products with excellent freeze-thaw resistance and corrosion resistance; these are procurement-registered products that maintain long-term structural stability even in sewage and wastewater environments.

Special Notes

• Proven technical expertise based on excellent procurement products: We hold patents related to polymer composite material manufacturing, as well as KS and Public Procurement Service excellent product certifications, securing numerous supply records for public institutions and local governments.
• Competitive edge in superior durability and corrosion-resistant materials: We possess composite material technology that offers superior chemical resistance and durability compared to general concrete and metal piping, providing differentiated performance in the sewage conduit sector.

Recruitment Information

• Main Hiring Positions: Manufacturing and production site staff, composite material molders, quality control staff
• Benefits: Four major social insurance plans, severance pay, lunch provided, etc.

💡 A Word from JOBPLOY
Korea Polytech Co., Ltd. is a company that manufactures glass fiber reinforced plastic pipes and composite material manholes, with a high proportion of on-site work such as molding, processing, and material loading within the factory. As we handle large piping materials and chemical resin materials, wearing protective equipment (dust masks, safety shoes, gloves) and following safety rules are essential. Since there is a lot of team work on-site, being familiar with basic Korean communication regarding process-specific work instructions and safety is very helpful. JOBPLOY recommends this company for those who value stable manufacturing environments.
