Full Cast Number Certification 20 May 2015 David As many of you have noticed we have begun to supply a cast number label on all of our production since the 1st of January this year. We believe that for all of our customers a generic letter of conformity was not good enough and you should be able to know exactly what the metallurgical composition is for every piece that you purchase from us, ensuring you know exactly what you are purchasing! We are currently the only UK manufacturer that offers this trace-ability. If you wish to know any more information about our full mill certification or anything else about our range of ground flat stock and gauge plate then please get in touch!
