The Advance Guardrail provides an alternative build method equally supported by the HSE for our wide and narrow aluminium towers. It uses fewer components than standard aluminium towering by replacing the different sized braces with a lightweight frame, so is easier to erect. Wide towers have a base area of approx. 1450mm x 1800mm, and are available in heights from 2.2 metres - 12.2 metres. Wide towers with a platform height of 8.7 metres and over are for internal use only. Narrow towers have a base area of approx. 850mm x 1800mm, and are available in heights from 2.2 metres - 12.2 metres. Narrow towers with a platform height of 8.2 metres and over are for internal use only. Please see 'spec sheet' for prices.
