Shear Resistance Rock Wool for Metal Sandwich Panel Core
Our sandwich panel rock wool core delivers high shear strength to meet structural load-bearing requirements for metal-faced sandwich panels. Featuring advanced 3D pleating technology, it provides exceptional shear strength perpendicular to the panel surface, creating an integrated load-bearing structure with metal facings.
- Core for metal sandwich panels in various building facades
- Core for long-span steel structure roof sandwich panels
- Sandwich panels in industrial plants
- Sandwich panel applications requiring structural shear resistance

3D pleating technology delivers up to 80kPa shearing strength with strong bonding between core and facings, effectively resisting interlayer shear deformation.
Core and metal facings form an integrated structure, preventing separation under wind, seismic, and thermal loads.
Meets Class A1 non-combustible standard with no burning or toxic fumes, meeting building fire codes.
High flatness ensures precise cutting, no edge chipping, suitable for continuous lamination production lines.
High acidity coefficient ensures corrosion and aging resistance, matching the service life of metal facings.
