Introduction to Double-Layer Trapezoidal Sheet Roll Forming Machines Commonly Used in Serbia
Below is a detailed introduction to **double-layer trapezoidal sheet roll forming machines** commonly used in Serbia, including market demand, equipment features, and applications:
I. Equipment Overview
Double-layer trapezoidal sheet roll forming machines** are specialized equipment designed to produce trapezoidal corrugated sheets with a dual-layer structure. Typically, two metal sheets (e.g., galvanized steel, aluminum) are roll-formed and bonded together, with optional insulation material (e.g., rock wool, polyurethane) sandwiched in between. This creates building panels that combine strength with thermal insulation, widely used in Serbia for industrial buildings, cold storage warehouses, and energy-efficient construction.
II. Core Structure & Technical Features
1. Dual-Layer Synchronized Forming System
Split Roller Channels: Separate feeding and synchronized roll forming for upper and lower metal sheets to ensure precise alignment of trapezoidal profiles.
Composite Modules: Optional functions like adhesive coating, insulation layer filling (with foam injection systems), or mechanical riveting.
2. Roll Forming Mainframe
Roller Sets: 16-24 sets to accommodate complex dual-layer deformation.
Material Compatibility: Processes steel, aluminum, or stainless steel sheets (thickness: 0.4-1.2 mm; width: 600-1200 mm).
3. Intelligent Control System
PLC or industrial PC controls for synchronized speed and tension to prevent misalignment.
Parameter memory for quick switching between profiles (e.g., trapezoidal waves with 50-150 mm height).
4. Optional Modules
Online Cutting**: Hydraulic or laser cutting (±1 mm precision).
Surface Treatment: Pre-coating (e.g., PVDF) or embossing.
Insulation Injection: For sandwich panels (EPS, rock wool cores).
