Why Use a GramLine SteelPlinth™?

A GramLine Steel Plinth™ has many unique advantages over timber plinths

  • Steel Plinth™ is made from quality assured ColorSealed® prepainted steel for high durability and great performance
  • Steel Plinth™ is attractive, has clean lines, matches the fence finish and colour, and will last a long time
  • Steel Plinth™ won’t rot and is not affected by termites
  • Unlike timber, Steel Plinth™ is not treated with toxic timber preservative chemicals that can leach into the ground and cause environmental problems
  • And of course, Steel Plinth™ won’t twist and warp over time.

Steel Plinth™ uses include

  • Weed wall applications
  • Retaining wall applications
  • Raised garden bed applications

Weed Wall Applications

  • Steel Plinth™ slows down weeds, rubbish, dirt, grass and even snakes from entering your backyard or property from under the steel privacy fence.
  • The Steel Plinth™ fits under the bottom SlimLine™ rail and inside the SmartPost® or SlimLine™ channel posts of your GramLine® steel privacy fence.
  • Why have timber sleepers or toxic copper-chrome-arsenate treated timber logs when you can have a Steel Plinth™ that finishes and matches your steel privacy fence superbly?

Retaining Wall Applications

Steel Plinth™ can be built up as a retaining wall to a height of 600mm, which equates to 5 lapped plinths. The SmartPost® or SlimLine™ channel posts may need to be re-enforced and the depth plus diameter of the concrete may need to be increased, depending on the height of the wall to be constructed.
The GramLine® Steel Plinth™ Retaining Wall has been certified and tested by an independent Structural Engineering firm.
