Production Line Performance & Features
Great Wall slitting line designed for processing coils of varied specifications, this production line completes the entire workflow from uncoiling and initial flattening to head cutting, slitting, and finally rewinding into coils with the required fixed width. Suitable for processing materials from thin sheets to thick plates, typically within a thickness range of 0.2 mm to 30 mm (depending on the machine model). As an integrated automatic coil processing equipment that combines mechanics, electricity, hydraulics, and pneumatics, it stands out for its user-friendly operation, rational layout, high automation level, and efficient processing capabilities.
Capable of handling multiple metal types, including carbon steel, cold-rolled sheets, galvanized sheets, silicon steel sheets stainless steel, aluminum alloys, copper, and other metals. Thanks to its advanced processing technology, the production line ensures consistent precision in coil width and flatness—effectively reducing material waste caused by dimensional errors, and meeting the strict quality requirements of high-end metal processing projects. Moreover, it is equipped with an intuitive human-machine interface (HMI) that allows operators to set parameters, monitor the production process, and troubleshoot simply, minimizing the learning curve for new users.
Versatile Application Scope
Welded Pipe Industry: It processes metal strips (such as carbon steel strips or stainless steel strips) into uniform narrow-width materials with precise dimensional control—these strips serve as the core raw material for welded pipe production, ensuring the subsequent pipe-forming and welding processes meet industry quality standards.
Automotive Manufacturing Industry: The machine specializes in processing high-strength steel strips, which are essential for manufacturing durable automotive components that meet strict safety and performance standards.
Solar Bracket Manufacturing Field: It precisely slits metal sheets (such as aluminum alloy sheets or galvanized steel sheets) into customized widths and sizes, supplying high-precision raw materials for assembling solar brackets—ensuring the brackets have stable structural performance to withstand outdoor environmental conditions.
Construction Sector: It processes galvanized steel and color-coated steel, producing materials that are widely used in manufacturing roofing products and structural components for construction projects.
