The panels are manufactured with durable metal sheets on both sides and an insulated core in the center, creating an integrated system that combines thermal insulation, structural stability, weather resistance and fast installation.

Depending on project requirements, sandwich panels can be supplied with different insulation materials, thicknesses, surface profiles, colors and connection systems.

Our sandwich panel systems are suitable for both external walls, internal partition walls and roofing applications, and can be customized according to architectural drawings, insulation requirements and project specifications.

Sandwich Panel Structure

A typical sandwich panel consists of three main layers:

Outer Steel Sheet
Pre-painted galvanized steel, galvanized steel or other coated metal sheet provides weather resistance, corrosion protection and structural strength.

Insulation Core
Different insulation materials can be selected depending on thermal, fire and acoustic requirements.

Common options include:

• Rock Wool

• EPS

• PIR

• PU / PUR

Inner Steel Sheet
Provides a clean interior surface while helping improve panel stability and durability.

The three layers are bonded together to form a lightweight but strong prefabricated building panel.

Main Sandwich Panel Types

Rock Wool Sandwich Panel

Rock wool sandwich panels are widely used in industrial buildings where fire resistance, thermal insulation and acoustic performance are important.

Typical applications include:

• Industrial workshops

• Warehouses

• Factories

• Power facilities

• Equipment rooms

• Logistics centers

• Fire-rated partition walls

EPS Sandwich Panel

EPS sandwich panels provide a lightweight and economical insulation solution.

They are commonly used for:

• Temporary buildings

• Prefabricated houses

• Warehouses

• Workshops

• Site offices

• Interior partition walls

• Storage buildings

PIR Sandwich Panel

PIR insulated panels provide excellent thermal insulation performance and are widely used in energy-efficient buildings.

Typical applications include:

• Cold storage

• Food processing facilities

• Industrial buildings

• Logistics warehouses

• Temperature-controlled facilities

• Commercial buildings

Wall Sandwich Panel

Our insulated wall panels can be used for exterior wall cladding and internal partition systems.

Features

• Lightweight construction

• Fast installation

• Smooth appearance

• Good thermal insulation

• Easy connection with steel structures

• Multiple surface finishes

• Custom colors available

• Suitable for modular construction

Wall panels can be installed horizontally or vertically depending on architectural requirements.

Roof Sandwich Panel

Roof sandwich panels combine insulation material with profiled steel sheets to create a complete insulated roofing system.

The profiled surface helps improve structural rigidity and rainwater drainage.

Suitable for:

• Steel structure workshops

• Warehouses

• Industrial plants

• Agricultural buildings

• Logistics centers

• Commercial buildings

Typical Steel Building Application

The sandwich panel system can be integrated with the complete steel building structure.

A typical steel building envelope system includes:

Main Steel Structure
Steel columns, beams and roof frames

Secondary Structure
Purlins and wall girts

Roof System
Roof sandwich panels or profiled steel sheets

Wall System
Insulated sandwich wall panels

Connection System
Bolts, screws and fastening accessories

Flashing System
Roof ridge, corner flashing, gutter and trim

This integrated system helps improve installation efficiency and overall building performance.
