1. Product Information

With optimal molding technology and ERW(Electric Resistance Welding) method, the pipe with outside diameter less than 92.mm

1. High strength, extremely thick(up to T/OD=25%, Sch.160) steel pipes -> Replaced by seamless steel pipes
2. Eddy Current Testing(ECT), non-destructive testing guarantees weld ability -> API J-55
3. The pipe with inside diameter of more than 16mm, and with its internal bead removed -> Automobile parts, Solid-drawn pipes, having strength for the products that require precision measurement.

2. The Application of the Products of MS PIPE

Based on 15years of experiences to manufacture steel pipe roll forming and the outstanding technology for roll design, we founded the company for steel pipe manufacturing in 2006, and made the company established as a material pipe specialty company.

1. In particular, due to the weight reduction of the materials(steel bar) for automobiles, we are manufacturing and supplying hollow steel pipes.
   - Steering Shaft, Rack Bar, Tie Rod, Axle Housing, Door Impact Beam, Propeller Shaft, etc.
2. Hydraulic machine, Machine parts; Cylinder rod, Bush, and Roll, etc.
3. Electric, electronic goods(mainly by applying Cold Rolled Coil); Comp case of Air Conditioner, etc.

3. Demanding Sties and Distribution Flow

1. After second processing by a company of drawing, or a processing company, the products are delivered to automobile companies(Hyundai Motors, GM), and electronic company(LG).
2. We have the capacity of designing and manufacturing to meet the diverse requirements of the demanding sites(outside diameter/shape/thickness/cost down)

4. Ways to Receive Orders

Adoption of mass customization method(Steel type, thickness and application is considered in the design work to meet the customer's requirements)
"O.E.M type of various products with small quantity(Steel type, thickness and application is considered in considered in the design work to meet the customer's requirements)"
