How Do You Make a Double-Drive Aluminum Gate?
Specify two compatible swing-gate leaves as one coordinated driveway system. Each leaf needs a suitable hinge support, and the pair needs a reviewed meeting detail, latch or lock, stops and any drop bolts required by the design.
Wonderful Metal supplies custom double-leaf swing gate configurations. Submit the measured clear opening and site layout so leaf sizes, hinge clearances, center gap and hardware can be agreed before manufacturing. Combining two unrelated single gates is not automatically a suitable double-gate solution.
Design Two Leaves as One Complete System
| Article | Planning requirement |
|---|---|
| Gate leaves | Coordinated dimensions, frame structure, infill and meeting geometry. |
| Hinge supports | One suitable outer support for each leaf, with appropriate foundations. |
| Hinges | Selected for leaf loads, mounting interface and swing geometry. |
| Meeting detail | Latch, lock, overlap or other specified closure arrangement. |
| Stops & drop bolts | Locations, receiver details and operating sequence where required. |
| Automatisation | Optional coordinated operator and safety-device scope. |
Equal-width leaves are common; unequal leaves can be discussed where access needs or site constraints justify them.
Measure the Clear Opening Before Choosing Leaf Widths
Measure between the intended support faces at the relevant elevations and check support plumb. Record ground levels across the opening and throughout both swing paths.
A nominal “12-foot gate” can refer to an opening designation rather than the combined physical width of two leaves. Twelve feet equals 3,657.6 mm. Specify the actual opening and hardware allowances on the approved drawing.
For a simple non-overlapping layout: clear opening = left hinge-side allowance + left leaf width + center gap + right leaf width + right hinge-side allowance.
Overlapping frames or other closure geometry require their own dimensioning. Do not assume two six-foot leaves fit a twelve-foot opening with no allowances.
Worked Sizing Example for a Double Gate
Hypothetical layout: a 3,600 mm clear opening, 40 mm allowance at each hinge side and a 20 mm center gap leaves 3,500 mm for the two leaves. Equal leaves would each be 1,750 mm wide.
This example explains the arithmetic only. The allowances are not Wonderful Metal hardware specifications. Final leaf dimensions must follow the selected hinges, latch detail, manufacturing tolerances and installation drawing.
Separate the vehicle’s usable passage width from leaf dimensions, support spacing and any reduction caused by hardware or the open leaves.
Can You Combine Two Existing Single Gates?
Possibly, after checking compatibility. Review frame strength, handing, dimensions, hinge attachments, infill alignment and the center closure detail.
Two independently designed single gates may have incompatible locks, edge profiles or support assumptions. Do not drill, weld or change a finished frame without an approved modification detail.
For a new project, ordering a coordinated pair makes the interface requirements clearer. Confirm which leaf is active for routine access and how the second leaf is secured.
Drop Rods, Cane Bolts & Center Stops
A drop rod or cane bolt can secure a leaf into a specified ground receiver. Its function, quantity and position depend on whether the gate is manual or automated and on the closure design.
A drop bolt is not a substitute for sound hinges, posts or foundations. A receiver must be compatible with the supporting surface, drainage and required clearances.
Coordinate center stops and opening stops as required by the system. Confirm hardware supply and pricing in the quotation; no fixed accessory price or automatic inclusion is assumed.
Gate Posts & Foundations for Each Leaf
Each outer hinge support carries its assigned leaf and operating forces. Select gate posts or verified structural pillars according to leaf dimensions, weight, wind exposure and hardware loads.
Both foundations require review even when the leaves are symmetrical. Soil, frost conditions where applicable, base-plate anchors and mounting substrate can affect the detail.
A narrow center gap or strong drop bolt does not compensate for leaning or inadequately supported outer posts.
Swing Direction, Slopes & Vehicle Access
Check the full opening arc of both leaves, including driveway slope, paving, landscaping and nearby structures. A gate that clears the ground when closed can strike rising ground as it opens.
Confirm inward or outward operation according to site conditions and local requirements. Keep the gate’s travel within the permitted area.
If swing space is unsuitable, evaluate a different entrance arrangement, such as an appropriately specified sliding gate, rather than forcing a double swing layout.
Manual or Automated Double Swing Operation?
Pour double swing gates, operator selection depends on leaf geometry, loads, mounting positions, wind and duty cycle. Coordinate the opening sequence where leaves overlap.
Automation-ready fabrication does not mean motors, controls or safety devices are included. Confirm the complete automation scope separately.
Use appropriate installers for electrical work and commissioning. Manual drop bolts and automated operation must be coordinated so a locked leaf is not driven by the operator.
Match the Gate to Your Aluminum Fence
Coordinate infill direction, spacing, height and finish with horizontal slat fencing, panneaux à lamelles verticales ou clôture à piquets.
Match appearance while retaining suitable gate-frame and support specifications. A wide moving leaf may need a different frame from a stationary fence panel.
Confirm material, profile dimensions, color reference and coating requirements on the order drawings.
Contractor Installation & Final Checks
- Approve the opening, leaf sizes, supports and closure detail.
- Prepare foundations or verify structural mounting locations.
- Install hinges and hang both leaves to the approved dimensions.
- Set alignment and clearances within the hardware limits.
- Install latches, drop bolts, receivers and stops as specified.
- Check both complete swing paths and closure sequence.
- Commission automation where included and inspect safety functions.

Wholesale & OEM Double-Drive Gate Supply
Pour custom aluminum gate orders, schedule both leaves, posts, hinges, closure hardware and automation interfaces. Identify the assembly format and separately packed components.
Contractor enquiries, wholesale fence projects et OEM manufacturing requests should include drawings, finish, quantities, inspection and packing requirements.
Confirm MOQ, sample approval, lead time, tooling and hardware prices in the quotation. Compare gate-leaf supply, complete hardware packages and installed-project costs on equivalent scope.

Foire aux questions
Can two single gates form a double-drive gate?
Yes, if the leaves, supports and center closure are compatible and designed together. Two arbitrary single gates should not be assumed interchangeable.
Will two six-foot leaves fit a twelve-foot opening?
Not automatically. Leaf sizes must allow for hinges, the center gap and closure geometry.
Is a drop rod included?
Confirm the quantity, specification and price in the order scope. Inclusion is not assumed.
Do I need a center post?
Not necessarily. Many double swing designs use outer hinge supports and a center meeting detail with stops or bolts as specified.
Can a double gate be automated?
Suitable configurations can be discussed, with operator geometry, electrical scope and safety devices confirmed separately.
Does custom sizing mean no site adjustment?
No. Accurate manufacturing dimensions still require verified supports, proper hanging, alignment and final hardware adjustment.
