Decoding our Part Numbers

Steel & Aluminum Products

The first letters in each part number are the descriptors for the type. Subsequent numbers describe the thickness of the material, followed by the dimensions of the shape. Thickness, height, and width are in inches, length is in feet.

[Type Code][Thickness] X [Width] X [Height] X [Length]

 For example:

A.188 X 1.50 X 1.50 X 20'

Angel, 3/16th thick, 1.5in wide x 1.5in tall, 20 ft Long
