The transverse directions are dimensions of a metal product that run perpendicular to the working direction of a metal product. In flat-rolled products there are two transverse directions. The direction through the thickness is known as the "short transverse" and the direction across the width is know as the "long transverse". It is sometimes difficult to determine the long transverse direction in sheet and plate products. To eliminate uncertainties many specifications require stenciling to be administered in the longitudinal direction. When viewing a product's microstructure, it is the direction perpendicular to the elongated grain in worked metal products.
