G3LB-M Mechanical Asymmetrical Initial Pinch 3 Roll Serie B Overview
Three-roll machines are evaluated by plate size, material strength, target diameter, pre-bending method, production volume, and operator workflow. Available configurations and capacities vary by model and project. Confirm the final specification against your material, part geometry, production target, utilities, safety requirements, and installation conditions.
Product Details

This mechanical model is designed for light to medium jobs. It is used in jobs up to 10 mm thickness materials. It is used in Aluminum Bendings, Air Conditioning Channels, Advertising Panels and Sheet Metal Covers.
What to Confirm Before Requesting a Quote
- Material grade and yield strength.
- Routine and maximum thickness.
- Working width.
- Target diameter and geometry.
- Pre-bending and cone-bending requirements.
- Drive, control, support, and handling needs.
Workflow and Integration Considerations
Plan loading, alignment, pre-bending, rolling, removal, fit-up, and welding around the chosen model. Final machine selection should be confirmed against current drawings, capacity tables, application tests, utilities, safety requirements, installation conditions, training needs, and service availability.
