Steel Roller Shutter Product Series

1. Insulated Steel Roller Shutter

Product Overview

The insulated steel roller shutter is an innovative composite door system constructed with double-layer galvanized steel sheets filled with high-density polyurethane foam. The total panel thickness is approximately 22mm, with each steel layer being 0.4-0.5mm thick. Manufactured through advanced continuous foaming technology, it perfectly combines the strength of steel with the insulation properties of foam.

Key Features

Excellent Thermal Insulation: Polyurethane foam layer density ≥60kg/m³, thermal conductivity ≤0.02W/(m·K), significantly reducing heat transfer and improving energy efficiency.

Superior Sound Insulation: Double-layer steel sheets and foam layer create multiple sound barriers, with noise reduction up to 8-12 decibels when combined with sealed guide rails and bottom gaskets.

Enhanced Structural Design: Streamlined panel cross-section with wind-resistant side locks provides wind pressure resistance up to level 10.

Intelligent Control System: Standard remote and manual dual operation, with optional Bluetooth and WiFi smart control modules supporting multiple opening methods.

Technical Parameters

  • Total panel thickness: 22±1mm

  • Steel sheet thickness: Outer 0.5mm/Inner 0.4mm

  • Foam density: 60-65kg/m³

  • Wind resistance: Levels 8-10

  • Thermal coefficient: K≤2.0W/(m²·K)

  • Operating temperature: -30℃ to +60℃

  • Color options: RAL standard colors, custom colors available
