Product Description

The ZSJH Steel Sandwich Panel System is a lightweight and energy-efficient building envelope solution designed for industrial, commercial and modular construction projects. Each panel consists of two durable coated-steel sheets bonded to a high-performance insulation core, creating an integrated system with reliable thermal insulation, weather resistance and installation efficiency.

Our sandwich panels are available with rock wool, EPS, PU or PIR insulation cores. Different panel profiles, colors, thicknesses and connection systems can be customized according to project drawings, climate conditions, fire-safety requirements and architectural preferences.

The system is widely used for steel structure warehouses, industrial workshops, cold-storage facilities, clean rooms, prefabricated buildings, agricultural buildings and commercial facilities.

Core Material Options

Rock Wool Sandwich Panel

Rock wool panels offer excellent fire resistance, sound insulation and dimensional stability. They are suitable for factories, warehouses, power facilities and buildings with higher fire-protection requirements.

EPS Sandwich Panel

EPS sandwich panels are lightweight, economical and easy to install. They provide reliable thermal insulation for warehouses, workshops, temporary buildings and general industrial facilities.

PU/PIR Sandwich Panel

PU and PIR panels provide high thermal performance with relatively low panel thickness. They are commonly used for cold rooms, food-processing facilities, refrigerated warehouses and temperature-controlled buildings.

Typical Specifications

Wall Sandwich Panel System

Wall sandwich panels provide an insulated and weather-resistant external envelope for steel buildings. The panels can be installed horizontally or vertically and are available with concealed fasteners for a cleaner architectural appearance.

Properly designed joints, flashings and sealing systems help prevent water penetration, air leakage and thermal bridging.

Roof Sandwich Panel System

Roof sandwich panels combine external roofing sheets, insulation material and internal ceiling sheets into one integrated component. The profiled outer surface improves drainage and load distribution, while the insulated core helps control indoor temperature.

Matching ridge caps, gutters, eave flashings and sealing accessories can be supplied as part of the complete roof system.

Cold-Room Panel System

Cold-room sandwich panels are designed for refrigerated warehouses, food-processing facilities and temperature-controlled environments. Thick PU or PIR insulation cores help reduce heat transfer and maintain stable indoor temperatures.

Cam-lock or tongue-and-groove connections provide tight panel joints and support efficient installation.

FAQ

1. Which insulation core should I choose?

Rock wool is commonly selected for projects with higher fire-resistance and acoustic requirements. EPS is an economical option for general industrial buildings. PU and PIR are recommended for projects requiring higher thermal insulation, such as cold-storage facilities.

2. Can the panel thickness and color be customized?

Yes. Panel thickness, steel-sheet thickness, profile, coating and color can be customized according to the project requirements. RAL colors are available.

3. Can you manufacture panels according to our drawings?

Yes. Please send us your architectural drawings, panel layout, dimensions, insulation requirements and project location. Our team will recommend a suitable panel system.

4. Are wall and roof panels supplied with accessories?

Yes. Matching flashings, ridge caps, gutters, screws, sealing materials, doors and windows can be supplied as part of the complete system.

5. How are the panels packed for export?

Panels are normally stacked with protective film, timber spacers, edge guards and reinforced straps. The packaging method can be adjusted according to container loading and transportation conditions.

6. Do you provide installation support?

Yes. We can provide panel layout drawings, connection details, installation instructions and remote technical guidance.
