Material Purchasing Influence Area

The steel specified by the designer in the drawing must be purchased by the purchasing department in the appropriate dimensions, quantity, and delivery time. If there is no specific ordering rule for the steel to be procured, the purchaser will typically refer to the valid material and product standards and indicate these in the order as a reference, Fig. 3.1. In addition, many delivery specifications have been created, which in most cases define the property requirements more narrowly than the national and international material standards.
