Product Overview
Color steel rock wool sandwich panel is a factory-laminated composite enclosure material composed of color-coated steel facings and an inorganic rock wool core. It integrates building rigidity, thermal insulation and fire-resistant performance to support fast-track building envelope construction.
Factory integrated lamination delivers stable, consistent finished performance and greatly simplifies on-site installation compared with traditional on-site assembled insulation systems. It is widely applied for industrial enclosures, commercial partitions, cold storage structures and general controlled-environment buildings.
We supply panels with thicknesses of 50–200 mm, standard effective width of 1000 mm, customizable lengths up to 12000 mm, and steel sheet gauges from 0.4 mm to 0.8 mm. Core density and final dimensions are confirmed according to project requirements. Negotiable MOQ is available for large projects and bulk orders. Our team reviews drawings only to verify production feasibility, without providing structural or fire-rated design selection.
Product Features
Composite construction
The rock wool core is continuously bonded to the steel facings during production, creating a single composite panel with stable thermal performance across the entire surface.
Thermal and fire protection
The mineral wool core provides thermal insulation and fire resistance in one material. Its inorganic composition does not support combustion, helping slow fire spread through building enclosures.
Enclosure rigidity
The steel facings contribute to the panel's cladding performance, allowing use as wall and roof cladding. The panels also provide sound insulation and vibration damping in building enclosures.
Fast installation
The large-format panels are crane-lifted and fixed directly to the building frame with self-drilling screws. Interlocking edges are designed for effective weather resistance when installed per project specifications, and installation labor is significantly reduced compared with traditional built-up systems.
Facing and Coating Options
Color steel sandwich panels are available with various surface finishes and coating systems. Available options include:
| Option Type | Description |
|---|---|
| Standard Color Coating | Polyester or PVDF coating in standard RAL colors; colors confirmed per project |
| Anti-Corrosion Coating | Enhanced coating system for aggressive environments |
| Embossed Finish | Embossed surface texture for reduced glare and improved aesthetics |
| Perforated Facing | Perforated steel sheet for acoustic applications (functional performance to be confirmed by project designer) |
Please specify the required facing type and coating when submitting your inquiry.

Note: Our service executes fabrication strictly to customer-provided specifications. The product is supplied as a building component; final design, panel selection, fixing systems, fire ratings, thermal calculations, cleanroom compliance, and code conformity must be verified by the project owner and their qualified engineering team. We do not provide engineering certification or compliance validation for specific applications.
Customization and Packaging
Panel thickness, core density, length, steel gauge, coating system, color, and packaging are all tailored to order specifications and confirmed prior to production.
Panels are packed in protective stacks according to their dimensions and quantity. Container load calculations and stacking configurations are finalized per order to prevent panel damage during transit and optimize freight costs.
MOQ: Quoted based on specifications and order volume
Sample availability: Panel samples are available on customer's request
Production lead time: Determined by specifications and order size
Packaging: Protective stacks / plastic wrapping / steel banding / final packaging arranged per order
OEM marking: Offered upon request (labeling or paint marking)
FAQ
Q1. What core densities are available for the rock wool core?
Typical core density ranges from 100 kg/m³ to 120 kg/m³. Final density is confirmed per project drawings and specifications. Other densities may be available subject to order quantity and production feasibility.
Q2. What panel thickness should I choose for my project?
Thickness selection depends on thermal performance requirements, local climate, and building design specifications. Please refer to your project's thermal calculation documentation for guidance.
Q3. Can panels be supplied in custom colors?
Yes. Standard RAL colors are available, and custom colors can be matched subject to coating system availability. Color samples are confirmed prior to production.
Q4. Are the panels suitable for exterior wall applications?
Yes. The panels are designed for both exterior wall and roof cladding applications. Panel joints and fixing systems should be selected based on project wind load and weatherproofing requirements.
Q5. How are panels joined together?
The panels feature interlocking male-female joints that provide effective weather resistance when installed per project specifications. Joints may be sealed with appropriate sealant or gaskets as specified in the project design.
Q6. What is the fire performance of the rock wool core?
Rock wool is an inorganic material that does not support combustion. The composite panel's overall fire performance depends on the complete assembly including joints and fixings. Please consult your project fire engineer for assembly-specific fire ratings.
