We will hold material for 30 calendar days, if a fabricator is specified. If material is not purchased at that point it will be returned to the active stock and sold to other customers. If your project does not start within 30 days of you selection, you may purchase the material and MGSI will store it for at minimal storage fee. We reserve the right to request your commitment to the material reserved, prior to the 30 days expiration date. Holding period for product in short supply may be changed to fit current company needs.We will hold material for 7 days if no fabricator is specified. It is the responsibility of the customer to contact us within 7 days and provide us with the name of a fabricator for the project. If we do not hear from the customer at the end of the 7th day, we will proceed to sell the material to other customers.


We require a full payment for custom orders. Payment must be received prior to placing the order.
