Double layer roofing sheet roll forming machine

Double Layer Roofing Sheet Roll Forming Machine — Custom Design for Brazil Market

1. Machine Structure

The Double Layer Roofing Sheet Roll Forming Machine is built with a middle-plate welded frame, ensuring high strength, precision alignment, and long-term stability during continuous operation.
It combines two forming layers on the same base, capable of producing two different trapezoidal roofing profiles according to the customer’s requirements in the Brazilian market.
This integrated design not only saves space but also reduces investment compared to two separate production lines.

2. Function and Working Principle

The machine automatically performs coil feeding, roll forming, cutting, and stacking according to the preset program.
Operators can easily select the desired profile layer from the PLC control system to switch production.
Each layer’s profile rollers are designed with high accuracy, ensuring precise shaping, smooth sheet surface, and consistent dimensions.

3. Material and Configuration

This model is suitable for processing Galvanized Steel (GI), Pre-painted Steel (PPGI), Aluminum-Zinc Coated Sheets, etc., with a thickness range of 0.3–0.8 mm and coil width up to 1250 mm.
Equipped with an efficient coil tension device, it ensures stable and smooth feeding, preventing material deviation and improving forming accuracy — a crucial feature for thin metal sheets commonly used in Brazilian roofing production.

4. Transmission System

The entire line uses a chain drive transmission system, providing reliable torque transfer, synchronized roller operation, and easy maintenance.
Compared with gearbox drives, chain transmission offers a cost-effective and durable solution suitable for high-speed production of roofing sheets.

5. Operation and Control

The system is controlled by a PLC with a touchscreen interface, featuring automatic counting, length setting, and profile switching.
It supports both manual and automatic modes.
Brazilian operators can easily set production parameters, while the built-in memory allows saving multiple profile settings, ideal for factories producing various sheet models.

6. Applications

This double-layer forming machine is widely used for producing roofing and wall panels in residential, industrial, and commercial construction.
Typical applications include warehouses, workshops, factories, and houses in tropical climates — exactly matching Brazil’s construction standards and popular trapezoidal profiles.
