Key Product Benefits

1. Maximum Fixing Flexibility with Dual Support Rails

Unlike basic open frames that only offer perimeter tubing, our frame includes both vertical and horizontal 40x40mm internal support rails. This means whether your timber palings, aluminium slats, or Colorbond sheets need horizontal or vertical screw points, you have solid steel backing behind every panel.

"Engineered with fully welded vertical and horizontal internal rails—delivering superior structural integrity for any custom gate project."

VERTICAL SUPPORT RAIL:

• Enhanced Central Integrity
• Reduces Vertical Deflection & Sway
• Optimal Zone for Precise Cladding Fixing (Slat, Picket, etc.)

HORIZONTAL SUPPORT RAIL:

• Prevents Gate Twisting & Racking Along Length
• Increases Framework Structural Rigidity
• Secures Fixing Points for Varied Cladding Types (Sheet, Slat, Colorbond®)

2. Ready for Sliding & Swing Gate Automation

Engineered with automation in mind, the rigid 80x40mm bottom rail provides a stable foundation for mounting sliding gate rack-and-pinion hardware or heavy-duty swing gate actuator brackets.

3. Weatherproofed for Australian Conditions

Pre-galvanised steel combined with a sealed white powder coat finish shields the frame against moisture, UV rays, chipping, and rust, ensuring your gate frame maintains its sleek appearance and structural integrity over time.

Frequently Asked Questions (FAQ)

What size options are available for these white steel gate frames?

Our white powder-coated gate frames are available in eight standard lengths to suit any opening size:

• 1m Frame
• 3m Frame
• 3.5m Frame
• 4m Frame
• 4.5m Frame
• 5m Frame

All size variants feature the same 1200mm overall height, heavy-duty 80x40mm bottom rail, 40x40mm top and side posts, internal vertical and horizontal support rails, and 100% fully welded steel construction.

What type of gates can I build using this white gate frame?

This versatile frame is engineered for both sliding gate (slide gate) and swing gate (single swing or double swing) applications. It serves as a structural foundation that you can clad with your preferred material to match your driveway or garden fence.

Why are both horizontal and vertical support rails important?

Internal vertical and horizontal rails (40x40mm) prevent the frame from sagging or twisting across wide spans. They also provide multiple structural fixing lines for attaching vertical pickets, horizontal battens, timber palings, or full-sheet cladding.

Is the gate frame pre-welded or flat-packed?

The frame comes completely welded throughout. There are no DIY bolt-together corners or weak mechanical joints, ensuring maximum structural strength and rigidity straight out of the box.

Can I attach electric automatic gate openers to this frame?

Yes. The extra-thick 80x40mm bottom rail and solid 40x40mm internal support structure are specifically designed to accept sliding gate gear racks, guide rollers, and automatic swing gate opener mounting brackets.

Does the white powder coating resist rust and fading?

Yes. Every frame is constructed using structural galvanised steel before receiving its premium satin white powder coating. This dual-layer system protects against corrosion, rust, chipping, and UV exposure under harsh Australian sun conditions.
