> **Executive summary**
> **An automatic light gauge steel packing line takes loose C and U profiles from a roll former and outputs labeled master stacks ready for logistics.** The line counts profiles, feeds them into small bundles, orbitally wraps the contact points, applies labels, and stacks the bundles into master loads. The PLC-synchronized line runs on standard ratings such as a 2500 kg stack load and 15 to 25 m/min wrapping speed. This guide covers the workflow and the specification range.

<h2 id="what-it-does">What the line does</h2>
An automatic light gauge steel (LGS) bundling and wrapping packing line takes loose C-stud, U-track and LGS profiles from a cold roll forming line. It turns them into labeled master stacks ready for global logistics and construction site delivery.
The line synchronizes with the roll former, so the finished profile moves straight into counting, bundling and wrapping instead of building up at the machine outlet. That removes the post-forming bottleneck that decides total output in high-speed roll forming production.
<h2 id="how-the-line-runs">How the line runs</h2>
The line follows six automated steps from profile output to unloading.
Precision sensors count the profiles and confirm the quantity of each small bundle against the preset parameters. A heavy-duty lateral transfer mechanism moves the profiles out of the roll former into the alignment zone. An orbital wrapping system then applies partial wrapping at the key contact points to hold the bundle together, and a real-time printer applies a barcode label on the top surface.
A specialized lifting device stacks the completed bundles into high-density master loads along the preset matrix, and a conveyor outputs the master stack to the unloading area for forklift pickup.
The whole sequence runs on PLC synchronization across all stations, coordinated by a central Siemens PLC with an HMI touchscreen operating station [manufacturer rating]. The system interlocks counting, lateral transfer, wrapping, labeling, and stacking with the parent roll forming line. This integrated architecture shares the same proven concept as OEM automated bundling and stacking lines—coordinating piece-by-piece infeed, automated alignment, multi-layer bundle forming, and discharge transfers from a unified control interface [manufacturer rating]. The HMI holds the tuning points that govern bundle rigidity. Calibrating the orbital wrapping tension achieves maximum bundle stability without deforming the thin-walled LGS profiles, removing the risk of loose bundles in transit without adding excessive film.
<h2 id="partial-wrapping-advantage">Partial wrapping advantage</h2>
The bundles are reinforced where the profiles touch, rather than covered edge to edge. The orbital wrapping system targets the key contact points, so the bundle stays stable in transit while film consumption stays low.
Targeted wrapping is what protects the zinc coating: the stretch film keeps the profile faces from rubbing and picks up less dust and moisture than full coverage configurations often retain.
Orbital film wrapping replaces traditional steel strapping here. Heavy structural steel tubes and hot-rolled sections typically rely on cold-rolled steel strapping applied with high radial force—often utilizing 25 mm or 32 mm straps under tension levels reaching up to approximately 13.7 kN at 0.54 MPa air supply [manufacturer rating, for reference]. On thin-walled light gauge steel (0.55 mm to 1.2 mm), such concentrated steel band forces easily crush profile lips, cut through flanges, and strip protective galvanizing. Orbital stretch film delivers continuous elastic recovery over a broader surface area, securing thin-walled profiles firmly without edge deformation.
<h2 id="master-stacking-and-load-protection">Master stacking and load protection</h2>
Completed small bundles are built into master loads by an automatic master elevator system, which stacks each bundle along a preset matrix so the finished load is dense and stable.
The elevator places every bundle in line, so the weight spreads across the load. The lower profiles are not deformed by heavy pressure. The result is a uniform rectangular load that shrinks the footprint in the warehouse and keeps its shape through stacking and transit.
<h2 id="labeling-and-traceability">Labeling and traceability</h2>
Each bundle carries a barcode label printed and applied in real time on its top surface, so the identity, grade and quantity of every bundle travel with it to the construction site.
That closes the loop between roll forming data and the finished load. With counts confirmed by sensors at the infeed and labels applied automatically, the manual entry errors that usually appear in large construction projects are removed from the material flow.
<h2 id="typical-specification-range">Typical specification range</h2>
The values below are the published standard ratings of this line. Line layout, indexing pitches, and handling mechanisms are engineered to order according to specific customer profile cross-sections, length ranges, and cut-off speeds [manufacturer rating]. Confirm the exact numbers against your roll former output per project.

| Master load | Stack matrix and max height |
| Utility | Power, air pressure and floor capacity |
| Site | Layout, guarding clearance and outfeed |
<h2 id="operation-and-safety">Operation and safety basics</h2>
The processing zone around the transfer, wrapping and stacking stations is enclosed by protective guarding, and a warning beacon cycles while the line runs. Operators stay clear of the guarded stations during automatic cycles and confirm the master load is clear of the outfeed before unloading.
Before a run, confirm the preset spec of the current profile size, the label stock and the film reel. Any change to the profile or bundle spec is entered on the HMI before the next bundle set, and servicing inside the guarding follows the lockout procedure in the manual.
<h2 id="maintenance">Maintenance essentials</h2>
Run the daily checks before the first shift. Confirm the counting sensors are clean and reading every profile, the film path is free of debris, and the label printer has stock and no ribbon faults.
Keep the transfer mechanism guides, the elevator chain and the conveyor drives lubricated per the manual, and check the air line pressure against the rating before high-volume runs. Watch the PLC alarm screen for sensor and drive faults and clear them before restarting.
<h2 id="engineering-faq">Engineering FAQ</h2>
Q: What profiles does the line handle?
A: Light gauge steel profiles, including C-stud, U-track and LGS profiles, at the machine's published stack ratings.
Q: How fast does the line wrap?
A: The published wrapping speed is 15 to 25 m/min, with the counting, labeling and stacking steps synchronized by PLC.
Q: Is every bundle wrapped completely?
A: No. The orbital system applies partial wrapping at the key contact points, which stabilizes the bundle with low film consumption.
Q: How are bundles identified?
A: A barcode label is printed and applied in real time on the top surface of each bundle for full traceability.
Q: What happens to the completed bundles?
A: An automatic master elevator stacks them into high-density master loads along a preset matrix, and a conveyor outputs the load for forklift pickup.
