RMG600 PSA Medium Grade


RMG 600 Medium Grade is a gravity lay panel. It incorporates a unique wrap-around construction which eliminates panel jamming caused by sharp edges. The design also improves edge strength and accessibility. RMG600 Medium Grade panel is world renown for its exceptional characteristics of strength and durability.

Category: Gravity Lay
Core Material: High Density Particle Board
Panel Construction: Galvanised Steel Wrap-Round Encapsulation

Core and Tray Thickness

Core: 30mm
Steel – Top Tray/Sheet: 0.5mm
Steel – Bottom Tray/Sheet: 0.5mm


The RMG600 is based on a 600mm square module, 31mm deep, constructed around a high performance chipboard core.  The galvanised steel shell comprises a top sheet that is wrapped and laminated around the panel.  This is then mechanically stitched to the bottom steel tray for greater strength and to provide full electrical continuity of the system.

Die-formed indentations in the panel bottom sheet allow positive location and retention within the system using the pedestal head lugs precision moulded into the ABS cap.

Feature Benefits

  • High edge strength reducing edge-to-edge deflection
  • Precision construction and location for accurate gridding
  • Solid underfoot
