Steel Side Frames
PGI Steel manufactures steel plate side frames for custom built machines. We stock a large inventory of A36, A572 Grade 50, 1020, 1045, 4140, and A514 plate ranging in thicknesses from 1/4″ to 8″ thick. After being flame cut in our plate burning/cutting department and Blanchard ground to within 0.005″ tolerance levels on our grinders, the steel side frames (pictured above) were drilled and machined on one of our many large CNC machining centers.
| Normal Tolerance Request | Thickness | Flatness | Parallelism |
| Blanchard Grinding | ± 0.005 | within 0.005 | 0.005 |
| Surface Grinding | ± 0.001 | within 0.003 | 0.001 |
Heavy Steel Side Plates for Custom Machines
Modern press calendar machines incorporate an L-Frame and an A-Frame roller system in order to allow the insertion of up to four large rollers. Multiple roller press machines can now handle laminating and coating paper, in addition to printing multi-colored, dual-sided, multiple layer paper products, such as calendars and cover papers. With up to 110″ wide x 162″ long x 42″ tall CNC machine capacity and bar mill table tops extending 84″ x 144″, we can machine steel side frames, steel table tops, and fabrications to nearly 20′ in length. Our largest Blanchard grinder can handle fabrications up to 45″ tall with a 128″ corner-to-corner swing and our largest reciprocal Mattison grinder can grind plate up to 48″ wide x 240″.
