Metal workshops generally require less treatment and can potentially last longer than their wooden counterparts. The galvanised steel panels which form the core structure of a metal workshop are roll formed with deep ribs for added strength. This provides extensive durability, protection against the worst weather the UK can throw at it and no treatment being required to begin with. However, a wooden workshop is a heavy-duty option and built-to-last. That’s why our BillyOh workshops come with a 10-year anti-rot, decay and insect infestation guarantee.
