3. Engineering Analysis & FEA


Finite Element Analysis (FEA) used to validate structural performance, load paths and stresses.


FEA supports:


  • Design verification
  • Structural upgrades
  • Safety and compliance checks
  • Equipment modifications and new builds
    This ensures every engineered component performs under real‑world conditions before manufacturing or installation.

4. Automotive Engineering


Design and build of specialised vehicle systems and transport solutions for mining, industrial and commercial applications.


Capabilities include:

  • Tray bodies (steel or aluminium)
  • Headboards
  • Canopies & cages
  • Tilt trays
  • Water carts & tank systems
  • Tipper bodies
  • Mudguards
  • Stainless steel fit‑outs (visors, steps, surrounds)
  • Bullbars
  • Lube carts
  • Plant & equipment trailers
    All builds are designed in‑house and supported by engineering certification where required. 

5. Industrial Engineering


Engineering support for fixed plant, infrastructure and heavy‑industry assets.


Capabilities include:

  • Machinery stands
  • Access systems (steel/aluminium)
  • Agitator tanks
  • Lighting plants
  • Mining wear packages (buckets, dump bodies, dozer blades)
  • Mining equipment overhauls
  • Structural upgrades for fixed plant
  • Custom bins & liners
  • Certified transport stands
  • Fabrication-integrated engineering for large industrial projects.

6. Engineering Certification & Compliance


Tefol works with a network of specialist certifying engineers to ensure all structural, mechanical and vehicle designs meet the associated Australian Standards.
Certifying disciplines include:

  • Structural engineering
  • Mechanical machine design & audits
  • Vehicle engineering (VSCCS)
  • Compliance reviews for plant and equipment
    This ensures every engineered solution meets its required design criteria before release or commissioning.
