Panel Construction
The Fuqiang fire-resistant rock wool insulated wall board is a three-layer composite sandwich panel. The outer face consists of a profiled galvanized steel sheet with a weather-resistant color coating. The structural core is a continuous layer of high-density rock wool insulation. The inner liner is a flat or lightly profiled steel sheet. The three layers are bonded together to form a rigid, self-supporting panel that can be installed directly onto steel purlins or wall framing without additional internal lining.
Surface Material and Coating
The outer and inner steel facings are manufactured from galvanized or aluminum-zinc coated structural steel. The surface is finished with a factory-applied color coating that provides resistance to corrosion, UV exposure, humidity, and light chemical contact under normal building exposure conditions. The coating system helps maintain panel appearance over the service life of the building and reduces the need for on-site painting or surface preparation. A range of standard colors is available, and custom color matching can be arranged based on project specifications or RAL references.
Rock Wool Core Performance
The insulation core of this panel is composed of high-density rock wool, a mineral fiber material derived from volcanic basalt. Rock wool is classified as an A-Grade non-combustible material and has a documented melting point above 1,000°C, making it suitable for projects where fire containment and flame spread limitation are specified requirements. The rock wool core provides a low thermal conductivity value of 0.043 W/(m·k), contributing to effective thermal insulation across the wall assembly. The core also provides sound insulation performance of ≥30 dB, reducing the transmission of external noise into occupied building spaces.
Joint and Edge-Sealing System
The panel system incorporates a tongue-and-groove interlocking joint profile along the long edges of each panel. The joint interface is sealed with a polyurethane edge-sealing compound that fills the connection zone and helps prevent water infiltration, air leakage, and thermal bridging at panel joints. This sealed joint design contributes to the overall airtightness of the wall assembly and supports a consistent thermal envelope across multi-panel installations. The joint system also assists with panel alignment during installation, reducing the skill level required for large-area wall construction.
Available Dimensions and Customization
The standard effective panel width is 950 mm. Available panel thickness ranges from 50 mm to 200 mm, allowing specifiers to select the appropriate insulation depth based on thermal requirements, fire rating targets, or acoustic performance criteria. Custom panel lengths can be produced to match specific structural bays or project floor-to-roof dimensions, reducing site cutting waste. Core thickness, surface profile, coating color, and panel length are all available as customizable parameters. OEM and private-label production can be arranged for qualified distributors and regional buyers.
Installation Compatibility
The panel fixing system uses concealed or exposed structural fasteners depending on the wall frame configuration. Panels are designed for installation onto standard steel purlin or cold-formed framing systems. Fuqiang supplies a complete range of matching installation accessories, including external and internal corner trims, window and door frame trims, base trims, ridge and eave flashings, closure pieces, and sealing strips. Sourcing the panel system and accessories from a single supplier simplifies procurement coordination and helps ensure dimensional compatibility on site.
Project and Climate Suitability
This fire-resistant rock wool wall panel is suitable for wall cladding applications in industrial facilities, steel-structure workshops, logistics warehouses, cold-chain distribution centers, commercial buildings, prefabricated plants, and modular construction systems. The panel is also applicable to building renovation projects where existing wall surfaces require upgraded insulation, fire performance improvement, or a refreshed exterior appearance. The sealed joint system and corrosion-resistant coating make the panel suitable for deployment in moderate to demanding climate conditions, including humid, coastal-adjacent, and high-UV environments where surface durability is a practical project concern.
