The materials used in B&G Sheds buildings have warranties that flow through from their suppliers. For our customer's peace of mind, all buildings use genuine Australian made products from Bluescope Steel and roller doors are from B&D Doors.

Our suppliers all have different warranties that vary from 1 yr to 25yrs, but most of the materials are Purlins and Colorbond Roofing materials which come from Lysaght / Bluescope. In general:

  • BlueScope Steel offers a warranty of up to 15 years* from the date of installation against corrosion to perforation by weathering in the natural elements, when used as roofing and walling for sheds and domestic garage applications located greater than one kilometre from a marine environment only. It applies to the following products when used in shed and large domestic garage applications (covering an area of not less than 18 square metres). Their warranty is attached below.
  • B&D Doors offer warranty on all rolling door and panel door products. Their warranty is attached below.

All buildings supplied by B&G Sheds are engineer designed and come with Plans and a Compliance Certificate which warrants the design for 6.5 yrs. That warranty is backed by the engineer's professional indemnity insurance.

Our installation crews warranty their work for a period of 12 months after installation. Any warranty claims should be reported directly to B&G Sheds. 

Note : Warranty terms and conditions apply. Warranties are not available for all products and applications. The duration and terms and conditions of available warranties vary according to product use and application.
