We started non- ferrous alloy sheet and strip production when the company was established in 1968
SHEETS & STRIPS
Poongsan's rolled products are the basic materials for an entire spectrum of manufacturing applications using copper and copper alloy sheets and strips. Poongsan sheets and strips are second to none, meeting rigorous internal quality control standards that exceed international standards set forth by JIS, ASTM, DIN, and other standards. It supplies large volumes of sheets and strips as starting materials for manufacturers and exporters. , - With Plant's International Standards Organization (ISO) 9002 certification, Poongsan earned a reputation for yielding high- quality products. This reputation is long acknowledged and respected throughout the world. Poongsan supplies its own production lines for value- added copper/ alloy products such as coin blanks in Nordic Gold, Cupro- Nickel, and Al- Bronze. Poongsan routinely produces various kinds of standard copper alloy sheets and strips for specific applications, but can custom- manufacture any alloy. These materials find applications in innumerable day- to- day household and industrial uses or are supplied to more advanced, high- technology industries.
* APPLICATIONS FOR SHEETS AND STRIPS
The applications for our copper- alloy sheets and strips vary significantly. The following industries, use them: * Building Materials * Electrical/ Electronic & High Tech * Industrial & Machine Parts * Consumer Items * Defense
* PRODUCTION
A large- scale continuous production system from melting and casting to slitting is in operation at the Onsan plant. It consists of horizontal continuous casting (HCC) and semi- continuous casting (SCC) lines, a hot rolling mill that can roll 6- ton slabs continuously, tandem mills, 20- hi cold rolling mills and heat treatment furnaces. Intermediate products are re- rolled by a precision rolling mill in various dimensions up to 630 millimeters in width and 0. 03 millimeter in thickness at a tolerance of 0. 002 millimeter. They are subject to a rigorous quality control system with modern inspection devices for precise dimensions, desirable physical properties, and surface conditions.
* PRODUCTS
Rolled products are categorized according to their alloy component and casting method: * pure copper * brass* cupronickel* phosphor bronze* and aluminum bronzeCertain applications require particular characteristics and certain alloys are best suited for some of these. Sheets and strips made of phosphor bronze or nickel- silver, for example, are widely used as electric or electronic functional parts. Nickel- silver is also used to produce food- packing cans with the most desirable qualities. Their qualities and physical properties are strictly controlled on the level required for machining. Spring materials, for instance, are tension- annealed for better elasticity and reliability. Poongsan engineers and technicians are world- class metallurgical experts. We can help you find the exact alloy for your application. There should never be any doubt that the customer will receive the right material, with a short- lead- time, at a reasonable price. Our goal is to always delight our customers with every order. Every step of the way, we, your partners at Poongsan, wish you the greatest satisfaction with our products and services. We deliver promptly, in excellent condition, and provide support after the sale.

* QUALITY
You should be assured of the quality of copper/ copper alloy strip you receive from Poongsan. It has undergone comprehensive mechanical and metallurgical testing in the laboratory. In our constant quest toward the ultimate customer satisfaction, we implement the Six Sigma program throughout our organization. First developed at Motorola in the 1980's, this comprehensive program uses statistical methods for process improvement: from filling out purchase orders to manufacturing products. Central to the implementation is considerable customer input. Aligning the requirements of the customer with our company's management, processes and culture are a top priority. Poongsan is implementing the program in stages, the ultimate goal being streamlining processes and operations, virtually eliminating mistakes or defects in everything we do to the absolute benefit of both our investors and customers. * Poongsan has been ISO 9002 Certified since 1994 * 6 Sigma quality control program in place
* SUCCESS
We know our mutual goal is to be successful in the global marketplace. We pledge to continuously improve our customer relationships. We will work with you to nurture a long- term partnership in which you will be guaranteed: * High- Quality Strips * On- Time Delivery* Exact * Reasonable Price
