Based in the industrial district of St Mary's, ABC Frames & Trusses has provided and serviced all clients with quality and reliability for over 30 Years. The company has shifted its objective over this period from providing an array of building supplies, to strictly producing prefab wall framestrusses and flooring systems for residential builds. 

At ABC we estimate, construct and deliver our products using the latest in both technology and machinery to provide our customers with a quality product, no matter how large or small the job is.


In 1969, Duilio Crosariol (Will), started the supply and install of conventional framing. Once this took off, he started a company in 1978 called Detailed Pre-fabrication Frame, located at Lansdowne Street, Guildford. Sydney Roof Trusses was the next purchase and was sold as a package deal. 2 Years later, Will met Peter Norris, and after much deliberation, they came to the consensus of agreeing to a new business name ABC Trusses. The acronym of ABC stood for Australian Building Components and was based at Bearing Road, Seven Hills for 6 Years. The two companies then formed a merger and took on the name ABC Frames & Trusses, which is still a household name and located at our now current location of Anne Street, St Mary’s. In 1992, ABC Supplies took shape for the purpose of selling building supplies such as:

  • Window cladding
  • Windows
  • Cavity door sliders
  • Roofing
  • Bricks etc.

In the early 2000’s, the company decided to supply and install roll formed facias and gutters, unfortunately, in 2008 with the Global Financial Crisis (GFC) impacting worldwide markets, resulted in a tremendous slackening of sales, thus, resulting in the scaling back of the company’s assets to only the manufacturing of frames, Trusses and floors which is still the predominant focus to this day.


The ABC Frames & Trusses team has in excess of over 40 years of combined experience in the fabrication of frames and Trusses. Over these years we have changed and developed passion for new and intriguing design and development, however, our methods of fabrication and the consistent measure of delivering a quality product has never changed.

Below is are examples of current and non-current projects completed by the ABC Frames & Trusses team.
