Its about Safety: wire balustrade creats a barrier to keep people safe. It is a safety barrier. It needs to be suitable for preventing injuries from a fall. Always best to build an Asset – Not a liability. And please remember the people you are keeping safe include your children, your sister’s or brother’s kids when they come over to play, your dogs and your parents who may or may not have their original hips. If you’re lucky enough, your grandparents. No one wants to fall or get injured. So keeping safety in mind when planning your balustrade is key. Thus, knowing regulations governing your wire balustrade makes the planning much easier.
Rules and Regulations: These are the rules and regulations pertaining to barriers and handrails in Australia.
You can’t go wrong if you stick to the Building Code of Australia (BCA) guidelines and gain approval from your local council to ensure your wire balustrade is legal and safe.
