Harvey Tuffspan
Natural Stone Coated Corrugated Roof Sheets
Rock Your Roof!
Harvey Tuffspan® combines the classic, versatile profile of corrugated steel with the legendary durability of Harvey’s natural stone-coated finish. It offers superior protection against UV rays, heavy rain and extreme impact with never-fade, never-paint peace of mind.
Superior Weather Protection
The stone-coated surface acts as a barrier against UV degradation and the onslaughts of harsh weather.
Never Paint
Because the rich colour is inherent to the natural stone granules themselves, it will never peel, flake or fade like traditional roof paint. You get a permanent, premium finish with no lifetime maintenance costs
Acoustic Dampening
The textured stone layer significantly absorbs sound, drastically reducing the noise of rain or hail on the roof for a quieter interior.
Zero Glare & Thermal Comfort
Unlike reflective metallic sheets, the matte stone finish eliminates harsh sun glare while naturally diffusing heat under the African sun.
Natural Stone Coat
In the constant battle against the elements, nothing stands up to nature like solid rock.
Never Fades – Never Paint.
Harvey Tuffspan® corrugated roof sheets consist of a steel substrate coated in natural stone. The natural, unpainted stone coating will not fade and never needs painting. It provides a naturally beautiful and durable barrier for decades of environmental onslaughts. Stone coated sheets are immune to discolouration and offer superior grit adhesion.
Create your Look.
Harvey Tuffspan Roof Sheets are available in a range of four natural stone colours to achieve your desired look.
Natural Colour That Cannot Fade
Harvey Tuffspan finishes use only the highest quality natural stone granules. These are bonded to the steel substrate through a patented, proprietary process – ensuring longlasting adhesion, vibrant colour, and exceptional durability for the lifetime of your roof.
