Production Line
For the production of heavy duty rack upright profiles, we recommend separating the punching and roll forming processes into two independent lines.
1. Flow Chart
(1) Punching line: Decoiler → Leveling machine → Punch machine → Recoiler
(2) Roll forming line: Decoiler → Roll forming machine → Cut-off → Out table
After punching, the perforated coil is recoiled and transferred to the roll forming line for profile forming.

Profile Information
In addition to rack upright profiles, this production solution is widely used for other cold roll formed profiles that require large numbers of holes or complex punching patterns, such as:
| Storage rack profiles | Solar mounting profiles |
| boltless rack upright | solar mounting C channel |
| rack step beam | solar support rail |
| rack support channel | perforated PV mounting channel |
| Electrical installation channels | Cable management profiles |
| strut channel | cable tray side rail |
| slotted C channel | perforated cable tray components |
| perforated support channel |
These profiles often have repetitive hole patterns and high production volumes, making pre-punched coil processing highly efficient.
How Does The Production Line Work?
Machine Details
Steel Coil Decoiler
Steel coil decoiler is used to unwind metal coils smoothly for feeding into roll forming, cutting, or punching processes.
Manual decoiler is a basic and economical option, while motorized and hydraulic decoilers are also available for higher efficiency and automation:
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 3/5/7/10 Ton | Expanding Range | 460-50mm |
Optional: Leveler
The leveler is designed to eliminate coil set and internal stress, ensuring flat and stable strip feeding into the punching section.
It is especially recommended for materials thicker than 1.5 mm, where deformation is more significant. By improving strip flatness, it directly enhances punching accuracy, die life, and overall line stability.
Servo Feeder
The servo feeder ensures precise and synchronized material feeding into the punching system through programmable control.
It delivers high positioning accuracy for hole spacing, even at high speeds. This reduces cumulative errors, and enables flexible production of complex hole patterns required in structural and industrial profiles.
Punching Unit
(1) Hydraulic Punching Machine
The hydraulic punching machine provides greater flexibility for customized hole designs and thicker materials. It operates with adjustable force and stroke, making it suitable for complex patterns or lower-speed applications. This solution is ideal for projects requiring versatility, precision under heavy load, and easier tooling adjustments.
(2) Punch Press
The punch press is a high-speed mechanical punching system suitable for continuous mass production.
It offers fast stroke rates and excellent repeatability, making it ideal for standardized hole patterns. Compared to hydraulic systems, it delivers higher efficiency and productivity, especially for thinner materials and large-volume manufacturing.
Recoiler
The recoiler collects the punched strip efficiently after processing, ensuring neat and controlled recoiling for storage or downstream operations. It maintains strip tension and alignment, preventing material damage or disorder. This improves handling efficiency, reduces labor intensity, and supports continuous, automated production flow.
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer requirements.
Other Customization Details
The machine comes standard with a blue main color and orange accents. Other colors can be customized free of charge.
The default metal nameplate is Goalon, which can also be customized at no additional cost.
Basic Services
Professional Packing
Machines are packed in plastic film and labeled for easy identification and assembly, and secured inside the container with steel cables.
Installation Guide
Free customized manuals, operationvideos, installationvideos, and remote video supportare provided.
Customers Who Benefit Most From This Solution
This production layout is particularly suitable for manufacturers with the following requirements:
1. Large production volumes
Factories producing rack uprights or similar profiles continuously benefit from the improved production efficiency.
2. Multiple product sizes or hole patterns
Pre-punching coils allows different punched coils to be prepared in advance, making order switching faster.
3. Factories planning long-term expansion
A punching line can supply punched coils to multiple roll forming lines, making it easier to scale production capacity in the future.
4. Manufacturers focused on stable and continuous production
Separated processes reduce downtime and improve the overall reliability of the production system.
Leveler is optional but recommended for coils above 1.5 mm thickness. It improves flatness, reduces internal stress, and significantly increases punching precision and die lifespan.
With servo feeder control, hole positioning accuracy can reach ±0.2 mm or better, depending on material quality and die condition, ensuring consistent pitch and high repeatability in mass production.
It processes steel coils such as galvanized steel, carbon steel, and stainless steel, typically ranging from thin gauge sheets to medium thickness depending on punching force and tooling configuration.
