However, in the actual press-working, the deep-drawability of steel sheets cannot be determined only by the value of and the measure of planar anisotropy, is more appropriate. In an ordinary cold rolled steel, R 90 {\displaystyle R_{90}} is the highest, and R 45 {\displaystyle R_{45}} is the lowest.
Metal prices are the prices of metal as a commodity that are traded in bulk at a predefined purity or grade. Metal can be split into three major categories, precious metals, industrial metals and other metals.

Steel studs are gaining popularity as a non-combustible alternative, especially for non load-bearing walls, and are required in some firewalls. In New Zealand, the required lumber size and spacing of wall studs are determined using NZS 3604 Timber-framed buildings table 8.2 for loadbearing walls and table 8.4 for non-loadbearing walls. [4]
