IBR sheet roll forming machine
Generally speaking, an IBR sheet roll forming machine can easily produce the metal roofing sheets in the speed of the 25 meter to 50 meter per minute with Inverted Box Ribs. Like other metal sheet roll former, IBR sheet roll forming machine has advanced PLC control system & Omron encoder and is capable to run both automatically and manually.
 
What is the IBR panel sheet?
IBR, abbreviated from “Inverted Box Rib”, usually applies for the outside cladding or roofing materials in commercial, industrial and residential buildings. Besides, the raw material is mostly Galvanized steel with the thickness from 0.4mm-0.8mm, and the width 925mm and 1219mm. Sometimes the customer also uses the PPGI as raw mateiral and the thickness also could be from 0.18 to 0.2mm if the customer uses SG550 hardness strong material.  The IBR roofing roll forming machine and corrugated sheet roll forming machine are TOP 10 metal roofing roll formers in African steel building industry. Here is one drawing profile for your reference:
 
Based on the IBR sheet features, we design machine like following:

The following part is about the details of the IBR machine:
 

1. For the gear it is important for the machine we use Chinese famous brand HRB
2. For the leveling part, we will use two layer and handrail adjustment.
3. For the roller we use the carefully polishing to make sure it will not damge the surface of raw material.

The main parts of the IBR roof panel roll forming machine is composed by the following elements:

1. Manual Uncoiler;
2. Feeding Guider;
3. Roll forming machine;
4. Hydraulic Cutting system;
5. PLC Control System;
6. Runout Table

For the IBR roofing machine above is about the slow speed like 25 meter per minute. We also have another options like 45 meter per minute, here is the machine pictures for your reference:
