Fireproof Metal Sandwich Panel Insulated Metal Wall/Roof Panels
Metal sandwich panels are the preferred choice for building roofing projects. Featuring low thermal conductivity core structures and high fire resistance, combined with customizable panel thickness and width, they precisely meet the personalized requirements of various construction applications.
These panels utilize a double-layer metal panel sandwich composite process with insulating core material filling the middle, creating a highly efficient thermal barrier structure. In hot weather, they effectively block external heat intrusion, while in cold conditions, they efficiently retain indoor heat, maintaining comfortable interior temperatures year-round.

Product Advantages & Features
- Lightweight and High-Strength: Significantly lighter per square meter than concrete, reducing building foundation costs and eliminating need for large hoisting equipment during installation
- Thermal Insulation and Sound Insulation: Low thermal conductivity provides winter insulation and summer heat protection; high-density core materials effectively reduce noise transmission
- Convenient Construction: Factory prefabrication allows direct on-site assembly, shortening construction periods by over 50% compared to traditional walls
- Durability and Aesthetics: Coated steel plates offer corrosion resistance and long service life; multiple color options available for unified building appearance
- Fire Resistance Rating: Inorganic core materials such as rock wool achieve Class A non-combustible rating, meeting various building fire protection codes
Product Applications
- Roofs and exterior walls of industrial plants, logistics warehouses, and steel structure workshops
- Public buildings including large supermarkets, exhibition halls, stadiums, and airport terminals
- Prefabricated houses, temporary construction sites, and container houses
- Cold storage facilities, cleanrooms (electronics factories, food factories, pharmaceutical factories), and other locations with high temperature, humidity, and cleanliness requirements
Frequently Asked Questions
What is a metal sandwich panel?
Metal sandwich panels are composite structural panels consisting of upper and lower metal panels with a middle core material bonded by adhesive. They feature thermal insulation, heat protection, fire resistance, sound insulation, light weight, and high strength, making them widely used in walls and roofs of steel structure buildings.
What core materials are available?
- Rock wool core (Class A fire protection, most commonly used)
- Glass wool core material (Class A fireproof, high cost performance)
- PU / PIR polyurethane (excellent thermal insulation effect)
- EPS polystyrene (economical type)
What materials are used for the metal panel?
Commonly used materials include color-coated galvanized sheets, galvanized steel sheets, stainless steel sheets, and aluminum-magnesium-manganese alloy sheets (corrosion-resistant, suitable for coastal areas).
What thicknesses are available for metal sandwich panels?
Conventional thicknesses include 50mm, 75mm, 100mm, 150mm, and 200mm. Custom thicknesses can be manufactured according to project requirements.
Are the width and length fixed?
Effective widths typically include 950mm, 1000mm, and 1150mm. Length can be customized as required, generally not exceeding 11.8 meters for transportation convenience.
