Extruded shapes are supplied with a “mill finish” and are subject to some possible minor surface imperfections.

The various manufacturing steps in the extrusion process, stretch & roll straightening, cutting to length, stress relieving, if required and final packing into wooden cases can cause the following surface condition:

• surface oxidation
• small black graphite marks on one of the flat surfaces of a shape
• superficial stains on some surfaces • small handling scratches or marks
• thin die lines on surfaces of some complexed shapes, although not a common occurrence
• a very thin layer of lubricant or liquid cutting oil on surface.

We do our best to supply extruded shapes to the highest quality standards and minimize any of the surface conditions mentioned above, however, if any of these are present, they should easily be removed during your final finishing operations.
