"Seonghwa EST Co., Ltd., established in 2007, is a specialized company that precisely processes and produces standardized steel plates, stainless steel, and aluminum products for industrial and automation equipment. To improve the inefficiency of traditional production methods, the company has built equipment automation and established a mass production system, possessing the capability to supply precision standardized sheet materials. By directly delivering standardized cut and processed materials to customers using precision NC equipment, it contributes to shortening additional processing steps and reducing production costs."

Business Areas

• Production of Steel Plate and Non-ferrous Metal Standard Products: Seonghwa EST Co., Ltd. produces standardized products from various metal materials such as steel plates, stainless steel, and aluminum used in industrial and automation equipment. In particular, we utilize various types of materials including SS400, S45C, SUS304, and AL6061 to supply precision standardized sheet materials tailored to customer requirements.
• Precision NC Machining and Automation Equipment Construction: To improve the inefficiency of traditional production methods, we have established equipment automation and apply high-precision cutting and side machining technologies using precision NC (Numerical Control) equipment. This contributes to shortening customers' additional processing steps, reducing defect rates, and increasing production efficiency.
• Prompt Supply through a Nationwide Distribution Network: Through our own supply network of over 30 nationwide agencies, we supply products to more than 15,000 companies, maximizing customer raw material procurement efficiency and providing prompt delivery services. We have established a stable supply system based on accumulated technical know-how and self-developed equipment.

Products

• SW Standard Products (S45C, SS400): We produce over 3,000 types of steel standard products, including various thick plates from 6mm to 10cm in thickness. Precision NC equipment is used for standardized cutting and surface machining.
• Stainless Steel Standard Products (SUS304): We produce over 1,000 types of SUS304 stainless steel standard products, both unmachined and surface-machined. We possess the technology to maintain high quality through surface micro-scratch prevention and uniform thickness control.
• Aluminum Standard Products (AL6061) and L-BRACKET: We produce over 1,000 types of AL6061 aluminum standard products, achieving precision equivalent to milling, thereby eliminating the need for secondary processing and contributing to production cost reduction. We also offer over 900 types of L-bracket products used in automation lines.

Special Notes

• Proactive Equipment Automation and Mass Production System: We have improved the inefficiency of traditional production processes and established a mass production system that quickly supplies standardized cut and processed materials using precision NC equipment. This significantly contributes to shortening customer processes and reducing defect rates.
• Diverse Materials and Standardized Product Range: We produce a wide range of materials, including steel plates (SS400, S45C), stainless steel (SUS304), and aluminum (AL6061), as well as over 6,000 types of standard products. This ensures high responsiveness to customer demands.
• High-Precision Processing Technology and Nationwide Distribution Network: We provide advanced secondary processing services such as 4-sided machining, precision cutting, and burr removal based on NC equipment, achieving precision similar to milling. Additionally, our distribution network of over 30 nationwide agencies enables prompt delivery.

Recruitment Information

• Main Hiring Positions: We primarily recruit for production and delivery sales management positions, which may include handling and transporting heavy objects.
• Benefits: We offer a 5-day work week, annual leave, congratulatory/condolence leave, and four major insurances (National Pension, Health Insurance, Industrial Accident Compensation Insurance, Employment Insurance). Welfare benefits also include excellent employee awards, severance pay, meal allowances, dormitories, and an in-house cafeteria.
