Fibreglass scaffolds available in Australia, are one of the preferred scaffolding types when used with or near Electricity source. This is because Fibreglass is non-conductive and hence safer to use.
Being lighter and easy to transport adds to the advantage of Fibreglass scaffolds. Especially because, it can shifted on the back of a trailer or small truck and is not as heavy to carry and/or assemble.
Regardless, it is best to get professional advice from people who are skilled and experienced in scaffolding.
