The new type fireproof rock wool / fiberglass wool sandwich panel is composed of two layers of high-quality color-coated steel sheets or other precision-rolled metal sheets as the outer panels. After roll-forming, the slit rock wool or fiberglass wool is rotated 90 degrees (so that the fibers are perpendicular to the upper and lower steel sheets). A high-strength, high-bonding, and high-fire-resistant adhesive is then used to firmly bond the premium rock wool / fiberglass wool to the metal panels, resulting in an aesthetically pleasing, flat, and rigid building panel. The finished panel offers excellent fire resistance, thermal insulation, and environmental friendliness, making it an ideal choice for industrial building envelope systems.
New Type Fireproof Rock Wool Core Material
New Type Fireproof Fiberglass Wool Core Material
The core material is an inorganic man-made fiber produced primarily from high-quality natural rocks such as basalt and gabbro, which are melted at high temperatures and then fiberized. It features extremely low slag and dust content and is non-absorbent.
The core material is rotated 90 degrees and oriented vertically to the steel sheets, significantly improving compressive strength. The core material is vertically arranged and staggered, eliminating gaps between core blocks and greatly enhancing overall rigidity.
The product uses a high-performance imported adhesive with excellent fire resistance. The adhesive is mixed and then sprayed onto the steel sheets, with an application rate of 600g/m², ensuring uniform and reliable bonding and achieving a bonding rate of 100%.
The facility currently operates three world-class fully automated continuous polyurethane foam production lines. These lines consist of equipment such as an uncoiling system, film laminating unit, forming machine system, steel plate preheating unit, six-component high-pressure foaming system, cutting system, transverse cooling system, and palletizing system.
With an annual production capacity exceeding 10 million square meters of energy-saving sandwich panels, including polyurethane, rock wool, and fiberglass wool panels. Products are widely used in cold chain storage, ski resorts, food processing, industrial buildings, large exhibition halls, and stadiums.
40m Ultra-Long Double Belt Conveyor
Ensures a more complete foaming process, resulting in better strength and quality of the finished panel.
Pentane Energy-Saving Foaming System
Upgraded to the current pentane foaming system for faster and more environmentally friendly production.
Corona Treatment System
Applied to the metal surface to increase adhesion, enhancing the bonding strength of the composite panel.
Panel Cooling System
Allows for gradual cooling, ensuring that the finished panel achieves complete curing and stability.
