What are the space / clearance requirements (for the swing arc, hinges, driveway slope) when installing a swing gate?

When fitting a manual swing gate, accurate space and clearance planning is essential for safe operation and long-term performance. The gate must have enough room to open fully, clear any ground slope, and avoid obstructions within the swing arc.

  1. Swing Arc Clearance – A single-leaf gate needs clear space equal to its full width to open. For example, a 4 m-wide gate requires roughly 4 m of unobstructed swing area behind the hinge line. Double-leaf gates reduce the swing radius of each leaf.
  2. Hinge Clearance – Allow at least 50–100 mm clearance between the gate edge and posts or walls for smooth hinge movement and to prevent binding.
  3. Ground Slope & Level – On sloping driveways, the gate must open uphill without scraping the surface. This can be solved by:
    • Installing rising hinges to lift the gate as it opens, or
    • Hanging the gate to swing downhill where possible.
  4. Vehicle & Pedestrian Clearance – Ensure there’s space for vehicles to stop safely clear of the swing path while the gate opens.
  5. Post & Foundation Alignment – Both posts must be vertically aligned and concreted to the correct depth (typically 300–500 mm) to support the swing load.

At Aremco Barriers, all UK-manufactured swing gates are supplied with detailed installation guidance, including clearance dimensions, foundation layouts, and hinge specifications. Each gate is built from galvanised and powder-coated steel, ensuring accurate operation and long-term durability for car-park, driveway, and industrial access points.
