CLEANER, SMOOTHER & STRONGER... hashtagFast Tread's unique Lamiboard soffit is manufactured with 2 materials bonded together giving you a far stronger, flatter finish (it's twice as strong as any single sheet on its own). The Lamiboard also eliminates weld spray marks which gives you a much cleaner & neater finish for your fire shaft. For cleaner & stronger stairs call us on 1300 751 701.
