Metalplate will check every piece in and out by piece mark (or description) on every order. If we have any discrepancies (short or over) with your paperwork, we will notify you immediately (usually within a day of receiving the material).
Our Houston facilities also helped pioneer bar coding of structural steel in the early 1990's. We can scan the loads in and out and provide data files to your customers to facilitate piece tracking. We utilize P2STS and Bartender to provide this service. If you have any questions regarding this system, we would be happy to provide you with information and contacts.
