Commercial & Security Fencing

As a Brisbane-based civil and infrastructure contractor, Golde Contractors Pty Ltd delivers commercial fencing solutions that prioritise compliance, durability and security. We understand that perimeter fencing is not just a boundary — it is a critical asset protection measure that must perform structurally, operationally and visually within its environment.

Our commercial fencing services are designed to integrate with industrial, utility and infrastructure projects, ensuring the finished installation aligns with site requirements while providing a robust security outcome. Whether the scope involves privacy screening, high-security perimeter fencing, or compliant construction site barriers, our systems are installed to meet relevant Queensland regulations and applicable Australian Standards.

Operating under disciplined project management and strong site supervision, our teams work efficiently to minimise disruption while maintaining strict quality control. We understand the standards expected across commercial, civil and utility environments — particularly where security, safety and durability are non-negotiable.

With more than a decade of industry experience, Golde Contractors brings a practical, solutions-focused approach to every project. We maintain clean, compliant sites and complete works to a professional standard regardless of scale — from targeted upgrades through to full perimeter installations.

If you require secure, compliant and professionally delivered fencing solutions in Queensland, Golde Contractors is ready to assist.

  GOLDE standard specification (for residential acoustic fence)

• Height: approximately 2.4 m to 3.0 m (depending on noise source, distance, elevation)
• Posts: treated timber or galvanised steel, deeper embedment/foundations than      standard fence.
• Rails: e.g., 3 rails of treated pine (or more if height exceeds 2 m) — example: rails 75×50 mm treated pine for a timber-acoustic fence.
• Boards or Palings: vertical treated pine boards butted together (no gaps), typically heavier boards than standard fence. “heavy acoustic” 15 kg/m².
• Sealing: Acoustic seal at panels/joints and at bottom (to prevent sound egress) as required in specification.
• Material durability: Treated timber, corrosion-protected steel, etc so the acoustic performance is maintained over life.
• Consideration of drainage, maintenance, gaps, vegetation etc: e.g., fences shouldn’t impede drainage, avoid ponding, must avoid gaps underneath etc

  Basic standards for a Koala proof fence:

• The fence must be both dog-proof and koala-proof.
• Fencing must be a minimum 1.8 m high in the context of koalas (and higher when also dog-proofing 2.4m high) where an infrastructure action is being assessed.
• There must be a minimum 50 cm wide scratch panel (on the outside of the fence) that prevents koalas climbing over. 
• It must be positioned 3 m clear of any retained trees or overhanging branches that koalas could use to bypass the barrier.
• There must be a permanently funded maintenance plan / monitoring arrangement in perpetuity.

Koala‑Sensitive Design Guidelines Version 2 (Queensland Dept. of Environment & Science):

• A summary of “koala exclusion fencing” (i.e., fencing that prevents koalas entering areas where they are at risk). 
• For example, fencing using metal sheet, timber without gaps, or chain-wire plus a “floppy top” or 600 mm exclusion element on top if using chain wire.
• The top of the ‘unclimbable’ section of the fence is to be at least 1.5 m  from the ground in one example.

•  Star pickets spaced every 2.5 m (so ~20 spaces over 50 m, ~22 pickets including start/end).  
• End/strainer posts at each end of run, and at any change of direction, ~every ~100 m for longer runs (not needed for just 50 m aside from ends).  
• Height of fence: 1.8 m (mesh height).  
• Top barbed wire (or top plain wire if preferred) above mesh.  
• Mesh fixed to star pickets, tie-wired every ~300 mm down the picket.  
• Bottom of mesh ~50–70 mm off the ground (or optionally buried ~100 mm if you want dig-proof).  
• Gate post and gate excluded in the 50 m run but leave space if required.
