Punching system (holes for bolts)
Adjustable size capability (optional)
Hydraulic cutting system

Typical setup:

Uncoiler (hydraulic recommended)
Leveling system
Punching unit
Roll forming machine
Cutting system

👉 Structural machines must handle thicker material and higher loads

Step 4: Choose Material

Common materials:

Black steel
Galvanized steel

Typical thickness:

1.5 – 3.0 mm
Heavy-duty: 3.0 – 5.0 mm

👉 Material strength is critical for structural performance

Step 5: Factory Setup

Requirements:

Space: 500–1,200 m²
Heavy-duty flooring
Crane or lifting equipment
Coil storage area

👉 Structural production requires larger and stronger facilities

Step 6: Build Your Customer Base

Target:

Steel structure companies
Contractors
Builders
Engineering firms

👉 This is a B2B, project-based market

5. Equipment Required

Core equipment:

C purlin roll forming machine
Hydraulic uncoiler
Punching system
Hydraulic cutting system

Optional upgrades:

Automatic size adjustment (C/Z interchangeable machines)
Stacker
Coil handling systems

👉 Punching systems are essential for structural products

6. Startup Cost Overview

Typical investment:

Machine: $70,000 – $250,000+
Materials: $20,000 – $80,000
Setup: $10,000 – $50,000

👉 Total startup: $100,000 – $380,000+

👉 Higher cost—but strong long-term returns

7. Production Capacity

Typical output:

10–25 meters per minute
High-volume production

👉 C purlins support large-scale manufacturing

8. Profit Potential

Business model:

Medium to high margins
Large project orders
Repeat business

👉 Structural products often offer better margins than basic roofing

9. Advantages Over Roofing Products

✔ Less competition
✔ Higher value product
✔ Long-term contracts
✔ Strong demand from construction

👉 C purlins are a core structural product

10. Challenges to Consider

Higher startup cost
More complex machines
Requires technical knowledge
Strict quality requirements

👉 This is a more advanced manufacturing business

11. Best Startup Strategy

Recommended approach:

Start with fixed-size C purlin machine
Focus on quality and accuracy
Build relationships with contractors
Expand into Z purlins or adjustable machines

👉 Grow into full structural production over time

12. Real-World Example

Startup scenario:

Product: C purlins (standard sizes)
Material: galvanized steel
Market: steel building contractors

👉 Result:

Large orders
Repeat contracts
Scalable growth

13. Startup Checklist

Before launching:
