  QUALITY - SAND TESTING  
 

Southwest Steel Casting Company achieved certification to ISO-9002 on December 26, 1996. In so doing, SWS becomes only the second foundry in Texas to distinguish itself in this manner.

 
 
 
 

One of the principle components of making a quality casting is the preparation of the sand into which molten metal is poured. To that end, Southwest Steel Casting Company operates a laboratory for the testing of sand to meet AFS standards and which conforms to Southwest Steel's ISO-9001 procedures.
