Feature: 1. Precise Adjustment: The three station edge roller allows for easy angle adjustment, great for bending and cleaning metal roof panels made of steel, aluminum, or copper. It can manufacture steel from 29 to 22 gauge, ranging from 5/8 inch to 4 inch (16 to 102 mm). 2. Uniform Bending: The unique design of the three station edge roller produces consistent bends, with the middle roller independently adjustable for creating precise bends. The three screw adjustment ensures stability and ease of use. 3. Premium Materials: Equipped with an upgraded aluminum alloy handle, the sheet metal roller bending machine offers a comfortable grip, saving energy and making movement easier. The 6 solid steel columns improve durability and strength. The connection between the solid steel column and the machine is made of premium brass, which has high strength and is not easy to be deformed and rusted. 4. Enhanced Grip: Upgraded to V shaped rollers, the edge rolling machine securely grips materials during bending, reducing errors and preventing slipping, providing a more reliable bending process. 5. Accurate Alignment: Featuring a precise imperial and metric depth gauge on one leg of the central roller station, ensuring accurate alignment of all roller stations for precise bending size when locked in place.
