With more than 6,000 line items, Parker Steel Company® is by far the largest distributor of metric size metals in America. Parker Steel® exclusively stocks metric size metals and takes pride in the service and selection we have built since the firm was founded in 1955.
When selecting from our large inventory, you can purchase as little as a single piece or a three ton bundle, and all stock is available for immediate shipping.
Our products are perfect for the customer who requires pre-sized metric stock in order to eliminate further machining.
At Parker Steel®, our service is top of the line. Arranging drop shipments is not a problem. We can even customize and cut the length of your order to meet your needs.
Should we not have a particular size or grade of metal you are looking for, please contact us and we will make every effort to find it for you as soon as possible.
Remember, we have a massive inventory of metric sized metals and we are always expanding our stock.
