What is accreditation and why is it important?

Accreditation formally recognises that we meet an authorised third-party's manufacturing standards.

Our ACRS and NATA accreditation guarantees:

  • Independent testing free from any commercial interests or influence.
  • You get the most up-to-date safety and testing measures.
  • The products you use are safe, strong and reliable.
  • Your peace of mind that you’re buying quality structural steel products made to Australian/New Zealand Standards, backed by multiple independent industry bodies.
