Sandwich Panel
Insulated Panels for Prefab Modular Buildings
Sandwich panels are a type of composite material with a metal surface (galvanized steel/aluminum/color coating) and an insulating core (PU, rock wool, or EPS).
- Use for: walls, roofs, cold storage, cleanrooms, warehouses.
- Thickness: 50 mm, 75 mm, 100 mm, 150 mm, 200 mm available.
What Is a Sandwich Panel?
A sandwich panel consists of three layers: two metal skin layers (typically galvanized steel or aluminum) sandwiching a low-density core material (polyurethane, rock wool, or magnesium oxysulfide).
This construction provides lightweight, high strength, good thermal insulation, and fire resistance, making it ideal for energy-efficient buildings. Here are the benefits:
- Fire Safety: Class B1 to A1 fire rating
- Thermal Insulation: 0.019-0.035 W/mK conductivity
- Waterproof: ≤3% moisture absorption
- Lightweight: 42-45 kg/m³ density
- Fast Installation: Pre-cut panels, no additional insulation needed
Sandwich Panel Applications
Cold storage and Refrigeration: Dairy freezers, meat storage, fruit/vegetable cold rooms
Cleanrooms and Medical Facilities: Pharmaceutical, hospital, laboratory walls/roofs
Warehouses and Workshops: Industrial storage, modular workshops
Food Processing Factories: Cold processing areas, walk-in coolers
Commercial Buildings: Fire-rated walls/roofs, energy-efficient facades
Prefab Buildings and Modular Homes: Container homes, prefab villas, portable restrooms

Magnesium Oxysulfide (MOS) Sandwich Panels are a chloride-free prefabricated building material engineered for high-demand environments. Each panel features a dense MOS core — a blend of magnesium oxide, magnesium sulfate, modifiers, glass fiber mesh, and performance fillers — bonded between two color-coated steel or galvanized steel facing sheets.
Unlike older magnesium oxychloride (MOC) panels, MOS sandwich panels address the industry's concerns about corrosion and moisture "sweating." So that delivers superior long-term performance across a wide range of construction applications.
Magnesium oxysulfide sandwich panels combine load capacity, moisture resistance, Class A1 fire resistance, thermal insulation, and acoustic performance in a lightweight system. Making them one of the most versatile prefabricated panels available today.

Handmade gypsum rock wool sandwich panels are a composite material featuring rock wool as a high-density core filler and smooth gypsum boards on both surfaces. Reinforced with an aluminum alloy or galvanized steel frame, these high-performance sandwich panels are manufactured through a manual composite process.
Gypsum rock wool sandwich panels offer outstanding fire resistance, thermal insulation, sound absorption, and moisture resistance. They are widely used in partition and ceiling systems for cleanrooms, pharmaceutical facilities, laboratories, and high-standard industrial spaces.

Handmade glass magnesium rock wool sandwich panels are prefabricated panels composed of glass-magnesium outer layers, rock wool core material (for thermal insulation), and edge sealing (typically galvanized steel). These panels are commonly designed for high fire resistance, excellent airtightness, and lightweight prefabrication.
Handmade polyurethane sandwich panels consist of two layers of high-strength panel material encasing a PU Foam core. The manufacturing process involves meticulous hand assembly, edge sealing, and pressing to create a high-performance composite sandwich panel. This handcrafted production process allows for greater flexibility in panel dimensions and surface treatments, making it ideal for both standard and custom applications.
Furthermore, they offer excellent sound insulation and fire resistance, meeting stringent building safety standards. These handmade polyurethane sandwich panels are widely used in logistics warehouses, factories, industrial buildings, commercial buildings, and residences—places where high levels of insulation and durability are required.

A Handmade Hollow Glass Magnesium Sandwich Panel (also known as a Hollow Glass Magnesium Manual Purification Panel) is a lightweight, prefabricated construction material commonly used in cleanroom environments, industrial facilities, and modular buildings. It consists of a core made from hollow glass magnesium board, which is sandwiched between two outer layers of color-coated steel sheets, stainless steel, or galvanized panels. The "handmade" aspect refers to its manual assembly process, which allows for customization in thickness, size, and fillers, making it ideal for precise applications.
Handmade aluminum honeycomb sandwich panels are formed by bonding two aluminum facings to a lightweight aluminum honeycomb core. This core is bonded to the two aluminum skins using high-performance aerospace-grade adhesives, creating a lightweight yet exceptionally rigid composite panel. Compared to other sandwich panels, it offers advantages such as low weight, excellent flatness, aesthetic appeal, scientifically designed joints, superior sound insulation and thermal properties, fire resistance, and ease of installation.
Handmade rock wool sandwich panels are high-performance composite panels featuring rock wool as the core material, metal panels as surface layers, and edge sealing as auxiliary structures. Unlike mechanically made panels from automated assembly lines, these panels are manually assembled, offering superior structural stability and customization flexibility.
With outstanding fire resistance, sound insulation, thermal insulation, and eco-friendly properties, hand-made rock wool sandwich panels are a preferred choice for cleanrooms, electronics workshops, pharmaceutical facilities, laboratories, and food processing clean zones.

Acoustic sandwich panels (also known as sound-absorbing sandwich panels or soundproofing sandwich panels) are architectural acoustic materials specifically designed to control noise transmission, reduce sound reflection, and enhance the acoustic quality of a space. Through their unique structural design and material combination, acoustic sandwich panels absorb sound wave energy entering their surface and convert it into heat, effectively reducing sound reflection and transmission.
Depending on their structure and intended use, acoustic panels can be categorized into various types, including perforated, slotted, fiber-absorbing, and porous foam, to meet the acoustic management needs of different frequency bands and environments.

Corrugated sandwich panels are composite panels consisting of two layers of corrugated metal, one on top and one on the bottom, with an insulating interlayer in between. The corrugated metal panels are typically made of aluminium, color-coated or galvanized steel, with a wavy (corrugated) structure. The interlayer is commonly made of insulating materials such as polyurethane foam, rock wool, polystyrene (EPS), or magnesium oxysulfide.
This structural design not only ensures the panel's thermal insulation properties but also enhances its mechanical strength and wind resistance, making it a multifunctional sandwich panel that combines thermal insulation and structural support.

Paper honeycomb sandwich panels are lightweight composite panels formed by thermally or cold-pressed bonding. They feature a honeycomb-shaped paper core as the core material, covered on both sides with plywood, cardboard, gypsum board, galvanized iron sheet, or other composite facing materials.
The internal honeycomb structure mimics the shape of natural honeycombs, providing excellent load-bearing and compressive strength. Being primarily made from paper—a recyclable and biodegradable material—it represents a genuinely eco-friendly product.

Phenolic sandwich panels are composite panels made of two layers of color-coated steel sheets with a phenolic foam core. These panels are suitable for roofs and walls, offering excellent thermal insulation, energy efficiency, and durability. Thanks to their fireproof and eco-friendly properties, they are widely used in prefabricated buildings, cleanrooms, and other high-safety environments.
Oven Rock Wool Sandwich Panels use high-performance rock wool as the core material and consist of color-coated steel or stainless steel sheets, crafted through a specialized composite process. They are commonly used in applications such as drying equipment (like baking tunnels), industrial furnaces, and heat treatment systems, offering exceptional insulation, heat resistance, and fire protection. They are increasingly becoming the preferred choice for building or renovating drying tunnels.
