Dura-Bar Stock Sizes
Dura-Bar stocks over 500 different sizes and shapes, for your convenience. Stock sizes are made to specific increments within a range, although a wide range of height and width combinations can be produced. Our standard bar lengths are 72" and 144" unless otherwise noted. We can produce custom lengths as non-stock items. All custom sizes and shapes are special order and are quoted individually at minimum run quantities.
1.500" to 26.560"
As-cast round bars are made to clean up at the nominal size. Additional stock is added to allow for out-of-round and normal imperfections in the as-cast surface. Stock allowance is a function of the bar diameter - see Stock Allowances for details. Other finishes available are Centerless Grinding and Centerless Turning, for demanding tolerance applications.
As-cast rectangles are made to the actual size with no allowance for machine stock added. Rectangles are cast to actual dimension, with clean up stock dependent on the height and width ratio. See Stock Allowances for details. Rectangles can be milled to achieve close tolerance benefits - see Services/Milling for details.
As-cast squares are made to the actual size with no allowance for machine stock added. Squares are cast to actual dimension, with clean up stock dependent on the height and width ratio. See Stock Allowances for details. Squares can be milled to achieve close tolerance benefits - see Services/Milling for details.
Trepanned tubes are stocked in 72" lengths, but can be produced in longer lengths upon request.

Tubes are sold with clean-up stock on the inside and outside diameters. See rounds Stock Allowances for O.D. The concentricity tolerance between the I.D. and O.D. is 0.250". See Services/Trepanning for details.
