Plastisol

Plastisol Sheeting is a very high quality Glavanised Steel sheet with a primer paint and the PVC rolled onto it giving a very durable sheet, that doesn't fade or scratch easily and with an expected lifespan of 30+years.

Fire: When tested, Class 0 in accordance with building regulations BS476 part 6 1989 and Part 7 1987.

Polyester

Polyester is a very useful in the agricultural uses as it has been stated as an acceptable material by a number of agriculture authorities. Also polyester is a cheaper alternative for roofing to other materials available. The polyester is coated upon zinc-coated steel in accordance to BS EN 10147. This type of roofing has a medium lifetime and should be recoated every five to ten years or less if there is pollution.

When handling polyester care must be taken as the polyester coating can easily be scratched.
Also sheets should not be slid against each other as this can also cause wear in the surface coating.

Galvanised steel

Now the base material for the Polyester and Plasticol roofing sheets, galvanised steel sheets have been used for over 100 years.
As long as the material is fitted and treated properly then it can last a number of years, however the material is very susceptible to corrosion especially the steel underneath the zinc coating, and with serious pollution can require replacing in as little as 18 months.
