How to produce high grade corrugated sheet?
We have two methods to produce corrugated iron sheet, one is made by roll forming machine; other one is made by barrel type corruagetd sheet machine

Here’s a step-by-step guide for producing metal corrugated sheets, which are commonly used in roofing and wall cladding:

A:Roll Forming Machine Production Process
1. Raw Material Preparation

• Material: Galvanized steel coils or other pre-painted steel.

• Thickness: Usually between 0.2 mm to 1.2 mm, depending on application.

• Width: Depends on the finished profile width (typically 762mm, 914mm, or 1000mm effective cover).

2. Decoiling

• The steel coil is loaded onto a decoiler.

• The decoiler unwinds the coil and feeds it into the machine.

3. Feeding & Guiding

• The sheet passes through guiding rollers to ensure it's straight and properly aligned.

• A pinch roller or feeder pulls the material into the forming section.

4. Roll Forming

• The core process happens in the roll forming machine.

• Multiple rollers gradually shape ( about 23 rollers) the flat sheet into a corrugated profile.

5. Cutting

• A hydraulic or fly-cut shear cuts the sheet to the desired length.

• Cutting is usually synchronized with the forming speed.

6. Output & Stacking

• The finished corrugated sheets exit the machine.

• They are manually or automatically stacked for packing.
  

B: Barrel Type Corrugated Machine Production Process

You need to purchase the sheets length like (3 meters or 4 meters) you want to produce, then the worker take the sheets into barrel type machine, one time can produce 3 sheets or 4 sheets, it is manually one, low speed.




If you want high-speed production(e.g., 10–15m/min vs. high-speed 30m/min lines), choose the molding machine solution; if you want to save costs, please choose the barrel type.
