Automatic Size Changing C U Purlin Machine | Haixing
The automatic size changing C U purlin machine from Haixing is designed to manufacture cold-formed C-shaped steel purlins and U-shaped steel channels for structural steel construction. Equipped with automatic size adjustment and C/U profile changeover functions, this roll forming machine supports manufacturers producing multiple structural steel profile specifications for different building projects.
Steel structure manufacturers often receive orders requiring different web heights, flange widths and finished lengths. A machine with automatic size changing functions allows operators to select supported profile dimensions through the control system, helping simplify production planning and reduce manual adjustments between different specifications.
Haixing provides customized C/U purlin forming equipment configurations based on customers’ profile drawings, steel material specifications and required automation functions.
Automatic Size Adjustment for Different C/U Steel Profiles
A key feature of the automatic size changing C U purlin machine is its adjustable forming system. The equipment can be configured to produce different C-shaped purlin and U-shaped channel dimensions within the approved production range.
Depending on the final machine design, the control system coordinates motorized adjustment mechanisms to reposition relevant forming components for the selected profile specifications.
This capability is useful for manufacturers producing multiple structural steel profile sizes. The actual adjustment range, supported steel thickness and setup requirements should be confirmed according to the approved equipment specifications.
Automatic Changeover Between C Purlin and U Channel Profiles
The machine is designed to manufacture both C-shaped steel purlins and U-shaped steel channels. These profiles have different cross-sectional geometries and may be specified for different structural framing applications.
The automatic C/U changeover system adjusts the relevant forming components according to the selected profile type. The actual changeover procedure, required operator actions and supported profile range depend on the final equipment configuration.
Combining C/U profile production with automatic size adjustment provides a practical solution for structural steel manufacturers handling different purlin and channel orders.
How the Automatic C/U Purlin Production Process Works
A typical automatic C/U purlin production line includes a decoiler, material guiding section, progressive roll forming stations, cutting equipment and an automatic control system. Optional punching or additional processing equipment may be integrated according to the required structural profile design.
During operation, steel coil material enters the forming section and passes through successive roller stations. These rollers progressively bend the steel strip into the required C-shaped purlin or U-shaped channel cross-section.
The finished profiles are cut to the specified length. The cutting method, optional punching arrangement and production sequence depend on the approved machine design.
Customized C/U Purlin Sizes and Steel Materials
The automatic size changing C U purlin machine can be configured according to different structural steel profile requirements. Important specifications include web height, flange width, lip dimensions where applicable, steel thickness, coil width and finished profile length.
Galvanized steel and other suitable structural steel materials can be considered according to the machine design. Material grade, yield strength, coating requirements and steel thickness should be reviewed before equipment manufacturing.
Haixing can evaluate customers’ C purlin and U channel drawings to discuss suitable forming roller arrangements, automatic size adjustment functions and optional punching or cutting equipment.
Applications in Steel Structure Construction
C-shaped steel purlins and U-shaped channels can be manufactured for a variety of structural steel applications, including industrial warehouses, prefabricated steel buildings, manufacturing workshops, agricultural facilities and commercial construction projects.
C-shaped purlins are commonly used as secondary structural members in roof and wall framing systems. U-shaped channels may be specified for compatible support, framing and connection applications according to the approved building design.
The appropriate profile type, steel thickness and section dimensions depend on the structural engineering requirements of each project.
Automation and Machine Selection
Before selecting an automatic size changing C U purlin machine, manufacturers should confirm the required C/U profile range, steel material thickness, automatic size adjustment method, C/U changeover functions, optional punching requirements, cutting system and target production capacity.
Depending on the selected control system, automation functions may include profile size settings, C/U profile selection, production length control, quantity counting and other production management features.
