Handrails are mainly installed for the safety and stability of a staircase. Nowaday, it is a regulatory requirement of new building staircases.
There are many options with stair handrails depending on the look you are after. PFC (Perth Fencing Centre) provide aluminium and stainless steel options suitable for internal or external requirement. The aluminium handrail can be powder coated to large range of colour to be a feature of your home.
