1. VShaped Roller Design: Featuring a Vroller design, the metal roof securely holds the material during bending errors and reduces the bending process. The hardened speed steel rollers ensure a longer lifespan, while the aluminum alloy handle provides a comfortable grip for the user. The side screws easily fix the lifting plate to the desired bending height. 2. 3Position Design The 3position roll edge bender offers a 3position design for stable and even bending without length limitations, ideal for creating leakproof and rainproof panels on metal roofs for houses, factories, etc. The roller design ensures material grip, reducing slippage and bending errors. 3. Upgraded Aluminum Alloy Handle: The improved aluminum alloy handle offers a comfortable grip, minimizing user fatigue during operation. This ergonomic design ensures a more pleasant and efficient bending experience. 4. Robust Construction and Stability: Made from materials and precision engineering, the metal edge rollers deliver reliable performance and stability. The sturdy construction, combined with effective design features, ensures consistent and precise bending results for various metal roofing applications.
