Fully Automatic C U Purlin Machine for Steel Buildings | Haixing
The fully automatic C U purlin machine from Haixing is designed for manufacturing cold-formed C-shaped and U-shaped steel profiles used in metal building construction. It combines progressive roll forming with automatic control and adjustable forming functions to support the production of different purlin specifications.
For steel structure manufacturers and building material suppliers, producing multiple C/U purlin sizes is an important part of fulfilling customer orders. A fully automatic production line can help organize profile adjustment, length control and repeat production according to the approved machine configuration.
Haixing offers customized purlin forming solutions based on customers’ structural profile drawings, steel material specifications and production requirements.
Automatic Size Adjustment for C and U Purlins
A major feature of the fully automatic C U purlin machine is its adjustable forming system. This allows the equipment to be configured for different C-shaped and U-shaped purlin dimensions within the supported profile range.
Automatic size adjustment can be managed through the machine control system and associated adjustment mechanisms, depending on the final equipment design. This is useful for manufacturers handling orders with different section heights, flange widths and finished lengths.
The actual adjustment range, changeover sequence and C/U switching method should be confirmed in the approved technical proposal.
How the C/U Purlin Production Line Works
A typical C/U purlin production line includes a decoiler, material guiding section, roll forming system, cutting equipment and automatic control unit. Optional punching equipment may be included according to the customer’s finished profile requirements.
The steel coil is fed into the forming section, where a series of rollers progressively shapes the material into the specified C or U cross-section. The machine control system manages production settings according to the selected configuration.
After forming, the finished steel profiles are cut to the required length. The exact punching, forming and cutting sequence depends on the approved production line design.
Custom C/U Purlin Dimensions and Steel Materials
The fully automatic C U purlin machine can be designed around customers’ required profile dimensions. Important specifications include section height, flange width, lip dimensions where applicable, steel thickness, coil width and finished purlin length.
Customers should provide detailed C/U profile drawings so that Haixing can evaluate the forming roller arrangement and supported adjustment range.
Suitable galvanized or other approved structural steel coils can be considered according to the equipment design. Steel grade, material strength and thickness should be confirmed before manufacturing.
Applications in Steel Structure Construction
C and U purlins are commonly used in prefabricated steel buildings, warehouses, industrial workshops, roof support systems and wall framing applications.
The appropriate profile dimensions and steel grades depend on the structural requirements of each construction project. Manufacturers can use a dedicated C/U purlin forming line to produce profiles according to approved drawings and customer orders.
Automation and Production Planning
When selecting a fully automatic C U purlin machine, manufacturers should evaluate the required profile range, steel thickness, size adjustment functions, punching requirements, cutting system and target production capacity.
Depending on the final control system, automated functions may include profile size settings, production length control and quantity counting.
Factory layout, material handling and finished profile collection should also be considered when planning the complete production line.
