We are a scale manufacturer based in Great Falls, Montana. We can build any length scale you need. Please see our other ads here or call us for pricing on anything you may not be able to find here. Rockwell Scales are 100% made in the U.S.A. with American labor. Rockwell Scales come with a 5 cement deck with supporting I-Beams underneath. We use steel I-beams to reinforce the deck so that the decking has plenty of support. We use heavier beams and closer spacing between load cells for less deflection. All wiring is 100% enclosed in conduit and not vulnerable to rodents. Our patented load cell design is self leveling and self checking making the system less complicated and easier to install. You can install these scales yourself using our blueprints and videos or we can install these scales anywhere. Please call for installation pricing. Warranty- Rockwell Scales come with a 20 year structural warranty. The best in the industry. No other scale company stands behind their scales like we do. Service- Rockwell Scales will travel anywhere in the world for installations and works with local dealers for any service you may need in the future. Our scales are easy to work on and contain no proprietary parts or electronics, unlike scales that contain digital load cells, so any scale company can service them giving you, the customer, a wide variety of options. Rockwell Scales also does service agreements and ourselves service Utah, Idaho, Wyoming, Montana and South Dakota.
