Single-Leaf vs. Double-Leaf Swing Gates
Swing gates open inward or outward on vertical hinge pivots. Selecting between single-leaf and dual-leaf configurations depends on overall opening span, driveway arc clearances, and structural post capacity.
Double-Leaf Swing Gates
Splits the driveway opening into two equal leaves meeting in the centre. Reduces inward swing sweep depth by 50%, providing an imposing architectural symmetry ideal for wider residential driveways.
Single-Leaf Swing Gates
A single continuous gate panel spanning up to 4.5 metres. Requires fewer motor actuators and simple center-free latching, well-suited for moderate openings with sufficient courtyard depth.
Hinge Positioning & Driveway Clearances
Precision hinge geometry and post foundations prevent sagging and ensure smooth gate leaf rotation.
Spherical Bearing Hinges
Heavy-duty multi-axis adjustable greaseable bearing hinges capable of carrying leaves in excess of 600kg without vertical drop or squeak.
Opening Arc & Gradient
Driveways with upward slopes require custom rising hinges or bi-folding leaf adaptations so bottom clearances clear ground elevation during swing.
Post Structural Anchors
Engineered steel core posts encased in brick pillars or freestanding heavy-wall structural hollow sections anchored to subterranean concrete footings.
Automation & Access Control Options
Linear Ram Actuators
Sleek stainless or powder-coated electromechanical rams mounted directly between post and gate, delivering strong locking force against wind pressure.
Underground Concealed Motors
Fully submerged waterproof motor boxes set into the driveway threshold, providing invisible automation that preserves pure architectural gate lines.
Articulated Arm Operators
Specially designed for wide masonry or stone pillars where deep hinge offsets prevent direct linear ram geometry.
Swing Gate FAQs
Can a swing gate open outwards toward the road?
Yes, but municipal regulations generally prohibit gate leaves from swinging past the boundary line onto public pavements or highways. Outward swing is only permitted when the entire swing arc remains within your private property line.
What happens if wind blows strongly against a swing gate?
Solid-infill swing gates act as wind sails. We install heavy-duty linear hydraulic or electro-mechanical rams paired with magnetic floor locks to firmly clamp the gate in both open and closed positions.
How deep do post foundations need to be for a heavy swing gate?
To resist rotational lever forces and avoid winter frost heave, foundation depths typically range from 900mm to 1200mm below ground level with high-strength C25/30 concrete.
