Expanded metal offers numerous design options: diamond and square meshes are available in different sizes. The meshes of MESHdesign Light are especially filigree. Thus, it has an open appearance in combination with the frameless expanded metal ceiling AMD-St 215. Expanded metal is acoustically effective thanks to acoustic inlays on the rear side.
- almost unlimited diversity of structures, sizes and surfaces
- filigree expanded metal meshes for open appearance
- acoustically effective in combination with sound absorbing inlays
MATERIALsteelCOATINGCOLOURLINEMOODLINEDEFINITION/DIMENSIONSAs a rule, expanded metal is defined using four dimensions:Example:RM 28 x 10 x 1.5 x 1.0a) mesh length: 28 mmb) mesh width: 10 mmc) strand width: 1.5 mmd) strand thickness: 1.0 mmDepending on the mesh dimension, expanded metal is available up to a width of 1,250 mm. The design and the stability of the ceiling construction are influenced by the shape and size of the mesh, the material and its thickness and also by the ceiling system itself. Thus, we recommend to check the project-specific feasibility and to make a sample of the mesh.VIEWING DIRECTIONAnother important aesthetic criterion is the viewing direction. Depending on the angle of vision, the expanded metal appears either more open or more closed.MESH ARRANGEMENTTo maximise the stability and the deflection properties of expanded metal ceiling panels, the mesh arrangement type A should be chosen.ACOUSTICSROOM ACOUSTICSEquipped with acoustic inlays, expanded metal ceilings achieve high sound absorption values.In case of expanded metal ceilings with open area exceeding 30 %, the mineral wool inlay is decisive as expanded metal is then absolutely sound-permeable.FIRE PROTECTIONBUILDING MATERIAL CLASSbuilding material class acc. to DIN EN 13501-1: A2 – s1,d0building material class acc. to ASTM E 84: Class ACOMBINABLE WITHEXPANDED METAL CEILINGSAMD-ST 215CORROSION PROTECTIONexposure class acc. to DIN EN 13964: A
