Steel manufacturers in the Korean steel reinforcement market are facing increasing competition. Construction businesses are in a recession because demands have decreased, too many facilities have been built, and more imported materials are coming from Japan and China. Korean steel manufacturers focus on domestic sales as a result of these difficulties in the business environment. To overcome these difficulties, manufacturers must find strategies for producing high value products, minimizing distribution expenses, and reducing costs. However, such temporary expedients are insufficient. Accordingly, our study investigating steel manufacturer salespersons and agents that purchase supplies uncovered suggestions for remaining competitive. First, companies must outdo their competitors by offering more competitive prices. Second, they must be ahead of their competitors in announcing their prices. Companies can present their expected selling prices by analyzing their manufacturing costs, future market unit costs, and distribution unit costs of the present market. If they select prices for products they will sell in the next month, the data indicate that they can still expect to make profits. The lowest selling price is calculated by analyzing the manufacturing costs. By setting prices more rapidly than competitors, manufacturers should increase their market share by increasing sales volume.
