NEW! Now Offering Plasma Cutting!

We now offer precision steel plate cutting with our new CNC plasma cutting machine. In addition to faster speed, there are many advantages to using this machine on steel 1″ thick or less: by utilizing a much smaller cutting path there’s less excess material, which means cleaner and prettier parts. Plasma-cutting steel eliminates the heat-effected zone of a cut, bringing less distortion on thinner plates, and it results in much tighter tolerances, making non-linear cuts much more feasible with a beautiful end result. Efficiencies in faster cutting times allow you to receive your material faster. Contact us today for more information on our new CNC plasma cutting machine!

Plate Saw Cutting

We can saw cut any of our plates (or yours) into flats, squares, or near-machined large rectangles. We can cut as small as a 3/16″ x 3/16″ all the way up to 18″ wide. We are more than happy to quote you on saw-cutting material that you supply. The saw is also perfect for making those hard-to-find flat sizes that the bar mills no longer roll. You pick the width, and we can make it!

Heat Treating & Shot Blasting

We have our own NC controlled car-bottom furnace at your disposal. We can normalize, stress relieve, or anneal in-house. This has a two-fold benefit: (1) it helps cut your machining costs by providing a product that has had the heat-affected zone removed from the part; and (2) it cuts your acquisition costs, as we don’t have to ship the material to an outside contractor.

Delaware Valley Steel also provides shot-blasting services to clean and polish steel after heat treating, which removes any carbon buildup for improved functionality and helps the metal regain its uniform texture and color.
