Key Feature | White Powder-Coated Steel Post

• In-Ground Concrete Mount: Extra length (2700mm) provides ample embedment depth for setting into concrete foundations—offering maximum overturning resistance for tall or heavy gates.

• Dual Layer Weather Protection: Built from high-tensile galvanised steel and coated with a durable White Powder Coat for ultimate resistance against Australian UV rays, rain, and coastal corrosion.

• Heavy-Duty Structural Profile: Features a 100mm x 100mm square hollow section (SHS) with a 2mm structural wall thickness to prevent flexing, sagging, or twisting.

• Versatile Gate & Fencing Support: Ideal for automatic driveway sliding gates, single or double swing gates, high privacy panels, and commercial perimeter fencing.

• Seamless Color Match: Blends cleanly with white aluminium slat fencing, Colorbond® gates, and modern architectural gate frames.

• Free Matching Cap Included: Supplied with a tight-fitting white steel post cap to block rainwater penetration and protect against internal rust.

 

Heavy-Duty 2.7m White In-Ground Steel Support Post

Ensure maximum stability for your gate installation with our 100x100x2700mm White Powder-Coated In-Ground Steel Gate Post. Engineered to suit demanding Australian residential and commercial environments, this extended-length metal gate post provides the deep footing embedment needed to support heavy automatic driveway gates, high-privacy swing gates, and long perimeter fencing runs.

Designed for Secure In-Ground Concreting

At 2700mm in total length, this post gives you approximately 600mm to 900mm of extra tail length to embed directly into a concrete footing below ground level. In-ground concrete installation provides superior leverage and load-bearing capacity compared to surface mounting—making it the ideal choice for high-wind zones, soft soil conditions, or heavy automatic swing gate setups that exert strong leverage on support columns.

Galvanised Strength & Premium White Finish

Made from high-grade galvanised steel and finished with a smooth, durable White Powder Coating, this post protects against severe weather, moisture, and fading. The internal galvanised core shields the steel tubing from rusting inside out, while the exterior white finish matches modern white gate frames, slat fencing, and perimeter posts across Australian homes.

Why Choose Our 2.7m White In-ground Gate Posts?

• Maximum Structural Stability: Sinking a 100mm x 100mm post into concrete creates a rigid upright column capable of supporting heavy gate automation rollers, guide brackets, and drop bolts.

• Custom Height Flexibility: The generous 2.7m length allows you to set the precise finished post height required for 1.5m, 1.8m, or 2.0m tall gates on sloped or uneven driveways.

• Built for Australian Gate Automation: Rigid wall strength prevents operational binding or misalignment when fitted with electric gate motors, heavy hinges, or magnetic latches.

 

Frequently Asked Questions (FAQ)

Q1: Why choose a 2700mm in-ground post over a bolt-down base plate post?

An in-ground 2700mm post is set deep into a concrete footing (typically 600mm - 900mm deep). This provides significantly higher resistance to leverage, ground movement, and wind loads—making it essential for tall gates (1.8m+ height), heavy swing gates, or installations into soil rather than existing concrete slabs.

 

Q2: What size gate height is this 2700mm post suitable for?

When embedded 600mm to 900mm into a concrete footing, this post leaves 1800mm to 2100mm of exposed height above ground, making it ideal for standard 1500mm, 1800mm, and 2000mm high gate frames.

 

Q3: Can I mount sliding gate hardware and swing gate hinges directly to this post?

Yes. The 2mm wall thickness of the galvanised steel tubing provides excellent thread holding strength for tek screws, rivnuts, or through-bolts used to mount heavy-duty swing hinges, sliding gate guide rollers, and gate stops.

 

Q4: How does the galvanised steel and white powder coating prevent rust?

The post undergoes dual-layer protection: the galvanised zinc layer shields the raw steel against moisture and rust formation, while the exterior white powder-coat layer acts as a tough barrier against UV rays, scratches, and harsh Australian coastal air.

 

Q5: Is the post cap included?

Yes. Each 2700mm white gate post comes complete with a matching UV-resistant white post cap to keep rainwater, dirt, and insects out of the hollow steel column.
