Cold roll forming machine mainly classified by raw material grade, section type (C-channel/U-channel/angle steel) and material thickness (light/heavy gauge), specializes in forming coil stock into various profiles through continuous cold rolling. Key features: high forming precision, consistent section shape, and stable operation. Advantages: advanced automation, energy efficiency, flexible profile customization, and low material consumption. Critical parameters: coil width/thickness range, forming speed, profile dimension tolerance, and maximum forming height. Extensively applied in construction, automotive, and infrastructure engineering industries.
