Yes, the Model 150 is excellent for structural steel. By applying high specific pressure across the width, it can correct not only twist and coil set but also longitudinal camber (curvature along the length). This is essential for welding preparations in shipbuilding or bridge construction where fit-up tolerance is tight.

The Model 150 is a high-power machine. It operates on 3-phase AC 380V. While the exact amperage depends on the specific motor sizing for your width, these machines are designed for continuous heavy-duty operation. The variable speed drive (1-10 m/min) helps manage power consumption by allowing you to run slower when leveling the thickest/hardest materials.

Due to the massive roll diameter (150mm), the minimum workpiece length is 250mm. This ensures that the heavy plate is engaged by a sufficient number of rolls to be pulled through the machine safely. Attempting to feed shorter pieces could result in the material dropping between rolls or causing a jam.

The "15/19" notation indicates a specialized configuration. It typically means the machine can be set up with 19 rolls for general heavy leveling, or adjusted/configured to use 15 rolls (larger pitch) for the absolute thickest materials (near the 30mm limit) where maximum roll strength and gap are required to allow the material to pass.

Yes, the Model 150 is a super-heavy-duty leveler. With a maximum capacity of 30mm, it can easily handle your 28mm plates. The 150mm roll diameter is massive, providing the leverage needed to flatten material that would otherwise require expensive heat treatment or pressing.
