Rock Wool Roof Sandwich Panels for Steel Building Roofing
1、Bingfa Steel Structure offers all kinds of rock wool roof sandwich panels, which are both durable & fire resistant, and give excellent sound, insulation & heat performance in all types of steel buildings, including warehouses, workshops, industrial and commercial projects, prefab structures, etc! The sandwich panel consists of two layers of colour coated (painted) steel sheeting, combined with an inner core of rock wool (or mineral wool) insulation to produce a sandwich panel with great fire resistance, good insulation properties, sound absorption, and long-lasting roof enclosure. 2、Our rockwool sandwich roof panels are specifically designed to fulfill three main purposes for steel building roof systems, namely safe and dependable, insulated and durable weatherproofing. You can choose the panel thickness, panel length, steel thickness, panel colour, etc., and customize it all (to match your project needs).
1.Good Fire Resistance The rock wool core provides strong fire-resistant performance, making it suitable for industrial buildings, warehouses, workshops, and projects with higher fire safety requirements.
2.Thermal and Sound Insulation Rock wool roof sandwich panels help reduce heat transfer through the roof system and can also improve sound insulation performance for steel buildings.
3.Durable Metal Roof System The color-coated steel sheets provide roof strength, weather resistance, and a clean exterior appearance for steel structure buildings.
4.Practical Waterproof Roofing Design Profiled roof surface, overlap joints, screws, flashing, ridge caps, and sealing accessories help create a practical roof system with good drainage and weather protection.
5.Custom Thickness, Length, and Color Panel thickness, length, steel sheet thickness, surface color, and roof profile can be customized based on your building design, insulation needs, and budget.
Rock wool sandwich roof panels are widely used for steel building and industrial roofing applications, including:
Steel warehouse roofing
Steel workshop roofing
Industrial building roofs
Commercial steel building roofs
Prefabricated steel building roofs
Factory and production facility roofing
Fire-resistant roof systems
Logistics warehouse roofing
Agricultural steel building roofing
Storage building roof systems
Rock wool roof sandwich panels are used as roofing material for projects that require durability as a roof enclosure, along with requirements for sound insulation, fire resistance, insulation etc.
A rock wool roof sandwich panel usually consists of:
Upper color-coated steel sheet
Rock wool insulation core
Lower color-coated steel sheet
Profiled roof surface for drainage
Overlap joint for roof installation
Matching accessories such as screws, ridge caps, flashing, trims, and sealant
This design merges the benefits and qualities of both types of materials, by providing durable and strong roofing panels, along with the insulation and fire-resistance properties of rock wool insulation, which makes the panels suitable for use in roofs of Steel Building Systems.
The rock wool sandwich panels for building roofs are appropriate for a steel structure project with an emphasis on fire safety, insulation, and long roof life. The use of rock wool roof panels improves the quality of the roofing enclosure, lowers the amount of heat transfer through the roof, and will provide a stable interior environment.
In addition, the prefabricated panel installation is often faster than other types of panel systems, which also contributes to the improved efficiency of the installation process. When correctly selected with the right type of roof profile, overlap, attachment hardware and sealant, Rockwool sandwich roof panels can provide you with a durable and quality roofing solution for your warehouses, workshops, factories, logistics buildings and other industrial projects.
Our sandwich panel production process is carefully controlled to ensure accurate dimensions, strong bonding, and consistent panel quality.
Steel Coil Uncoiling
Color-coated steel coils are loaded onto the uncoiling machine, leveled, and continuously fed into the production line. Protective film may also be applied to reduce scratches and surface damage.
Steel Sheet Roll Forming
The upper and lower steel sheets pass through roll-forming equipment to create the required panel profile, surface pattern, and edge shape.
Core Material Feeding
Rock wool or other insulation core materials are transported into the production line according to the required panel thickness and specification. The core is positioned carefully to maintain consistent panel structure.
Adhesive Application & Edge Sealing
Adhesive is applied evenly between the metal sheets and insulation core to create a stable bond. Panel edges may also be formed or sealed according to the selected joint design.
Double-Belt Pressing & Automatic Cutting
The metal sheets and core material pass through the double-belt pressing system, where they are continuously bonded and formed. The finished panels are then automatically cut to the required project length.
Finished Panel Stacking & Packaging
The completed panels are inspected, stacked, labeled, and packed with protective materials. Proper packaging helps protect panel surfaces and edges during storage, container loading, and delivery.
