What is a L purlin used for?
L-shaped purlin plates serve as beams that support the mid-span of rafters and are, in turn, supported by posts. By providing this intermediate support to the rafters, they enable longer spans than what would be possible with rafters alone, thus facilitating the construction of wider structures. This type of support beam is a common feature in large, historic barns across North America.
Advantages of the L-shaped Steel Channel Purlin Machine:
- The machine can manufacture purlins of varying dimensions without the need to change rollers or spacers.
- The L channel production equipment does not require a different cutter for producing various sizes.
- The L-shaped roll forming apparatus offers user-friendly operation and comes with low maintenance requirements.
- With an automated roll forming system for L-shaped steel, it’s possible to produce an infinite range of sizes within the machine’s capabilities, which optimizes material usage.
- The steel profile purlin machine provides the option to punch holes at any desired location on the web or flange sides of the purlin.
Workflow Diagram
The primary workflow for the L-shaped Purlin Roll Forming Machine proceeds as follows:
Uncoiling Station → Forming Stations → Hydraulic Power Unit → Automated Control System→ Automatic Cutting-off Section → Product Collection Tables
This streamlined process ensures efficient production from raw material uncoiling through to the final product being ready for use. Each stage is designed to work harmoniously, ensuring precision and consistency in the manufacturing of L-shaped purlin plates.
