Metalplate is happy to provide a Certificate of Compliance with any applicable specification when requested. If you will notify us in advance, we are happy to include this certificate of compliance with the invoice as soon as the order is complete. However, we understand there are instances when Certificates are sometimes requested after a job has been completed, we have the capability to provide Certificates for any job we have processed and would only need an invoice number or purchase order/job number along with the date we processed the order.
