  • AS 3600 — Concrete Structures (Australian Standard)
  • AS 1379 — Specification and Supply of Concrete
  • Minimum 32MPa compressive strength at 28 days
  • Steel-reinforced with deformed bar to AS/NZS 4671

Steel Post Standards

All steel posts — including C-Channel PFC and H-Beam UC profiles — are sourced from certified Australian and international steel mills and comply with:

  • AS/NZS 3678 — Structural Steel — Hot-Rolled Bars and Sections
  • AS 4100 — Steel Structures
  • Hot-dip galvanised or primed finish options available on request

Engineering & Council Compliance

For walls requiring council approval or a structural engineering certificate, our products are suitable for use in engineer-designed retaining wall systems. Visit our Engineering & Council Rules page for state-by-state height limits and DA requirements.
