What Are The Sandwich Panels?

The sandwich panel is widely used for wall and roof enclosure systems in industrial and commercial buildings.
Each sandwich panel consists of a central insulation core and metal cover panels on both sides. It combines high strength and high stability through a continuous molding process.
It should be noted that the sandwich panel is not used as a load-bearing structural material. Instead, it is primarily used for functions such as insulation, fire prevention, sound insulation, airtightness, and quick installation. The sandwich panel is an indispensable enclosure system solution in modern prefabricated buildings.
For projects such as industrial plants, cold storage warehouses, and clean rooms, selecting the right custom sandwich panel manufacturer will directly affect construction efficiency, operating energy consumption, and long-term maintenance costs.
How to Produce The Sandwich Panels?
Raw Material Inspection
All panels will pass equipment inspection before going online to ensure that its flatness is controlled within 0.5 mm/m, providing a stable foundation for subsequent shaping.
Unrolling
The metal coil passes through the unrolling machine and enters a multi-pass leveling rolling system, effectively eliminating warping and internal stress on the panel surface.
Forming
After entering the forming machine, the panels are gradually pressed by multiple progressive rolls to form the side locking structure and panel reinforcement ribs. This enables panels to maintain lightweight while having higher structural stability.
Filling
According to different applications, fill the core materials such as PU, rock wool or EPS so that the panel can be precisely matched in terms of insulation, fire resistance, or sound insulation performance.
Cutting

After the core material is filled, the flying saw machine rough cuts the panels while continuously conveying. Cutting length is automatically controlled based on preset parameters.
PU Edge Sealing
The edge sealing machine either sprays a special PU sealant onto the panel’s end face or uses an aluminum alloy edge strip combined with PU foaming to fill the gap.
For cold storage and cleanroom panels, it will embed additional low-temperature-resistant sealing strips to maintain airtightness, moisture-proofing, and no core material exposure at the end.
Curing
PU core panels require 24–48 hours of curing to ensure complete foam curing and a stable density of over 40 kg/m³. While the rock wool or EPS core panels require curing for 12–24 hours to ensure the adhesives are fully cured and the structure is stable.
Fixed-length Cutting
After curing, the panels enter the fixed-length cutting process. Per the order requirements, the final size is cut to ensure a high degree of alignment with the construction drawings.
Testing
The finished sandwich panels will undergo inspections for dimensions, tolerances, appearance, and key performance to ensure that each core panel delivered to your site complies with the technical requirements.

Performance Specifications of Custom Sandwich Panels
Thermal Conductivity
The thermal conductivity (U-value) of sandwich panels is typically controlled between 0.20 and 0.50 W/m²·K, reducing heat loss in the building envelope. This means that in steel-structure factories, warehouses, and cold-chain buildings, you can significantly reduce energy consumption for cooling and heating throughout the year, helping the project achieve more stable, predictable long-term operational cost control.
Fire Resistance
Depending on the selected core material, the sandwich panel can achieve A2 or B1 fire resistance. This could meet the requirements for fire separation and fire-resistance performance in industrial and commercial buildings.
Structural Performance

The sandwich panel shows stable wind pressure resistance, panel surface flatness, and connection strength. In projects with high installation precision requirements, this structural consistency can reduce the complexity of your construction adjustments and improve overall installation efficiency.
Sound Insulation
The sandwich panels’ air sound insulation value (Rw) can reach 40 dB, effectively reducing noise from equipment operation and the external environment. This enables it to better suit industrial facilities, logistics centers, and commercial buildings, helping you create a quieter, more comfortable work and usage environment.
Considerations of Custom Sandwich Panels
Application
Before customizing the sandwich panels, it is necessary to clarify their applications, such as industrial plants, cold storage facilities, clean rooms, or commercial buildings. Different applications prioritize insulation, fire resistance, airtightness, and durability, which directly affect the selection of core materials, panel types, and connection methods.
Performance Requirements
It is recommended that you clarify the requirements for thermal conductivity, fire resistance level, sound insulation performance, and structural strength, based on the project’s local climate conditions, usage functions, and applicable regulations. Clear performance goals will help us provide you with more precise and implementable solutions during the design stage.
Specification
The sandwich panels’ width, length, thickness, and connection structure need to match the height of the building structure system. Reasonable specification design reduces on-site cutting and rework and significantly improves installation efficiency, thereby lowering overall construction costs.
