A bottom track slide gate rolls on wheels along a rail set into the ground. It's the cheapest wide slide gate to build and the one we replace most in Winnipeg, because frost heaves the rail and snow and ice stop the wheels. For almost every Manitoba site the answer is a cantilever gate that never touches the ground; a bottom track only makes sense indoors, under cover, or on very wide openings with no room for a cantilever.
A bottom track slide gate (sometimes called a V-track or ground-track gate) rolls on wheels along a steel rail set into the ground across the opening. It's the cheapest way to build a wide slide gate, and it's the gate type we replace most often in Winnipeg.
How They Work
The gate panel sits on V-groove wheels that ride an inverted-angle track bolted or embedded across the driveway. Guide rollers on the receiving post keep the top of the gate upright. Because the ground carries the weight, the gate panel doesn't need the extra counterbalance length a cantilever gate does, so the structure is lighter and the opening can be almost as wide as the panel itself.
Why We Rarely Recommend Them Here
The track is in the frost zone. Manitoba ground heaves every spring. A track that was level in October is a hump or a dip by April, and the wheels bind or jump the rail.
Snow and ice stop the gate. Any packed snow, ice ridge, or gravel on the rail becomes a wheel stop. On a bottom track gate that usually means the operator stalls, trips its obstruction sensor, and the gate stays open — or someone shovels the track every morning.
The track is a trip and plow hazard. Plow blades catch it. Forklifts and trucks flatten it. Once the rail is bent, the gate is out of service until the rail is cut out and replaced.
Maintenance never ends. Wheels, bearings and the rail itself wear in grit and salt. A cantilever gate with sealed trucks has no comparable wear point.
When a Bottom Track Gate Still Makes Sense
- Indoor or fully covered openings where the track never sees snow or frost
- Very wide openings (80 ft+) where a cantilever counterbalance would run out of fence line
- Paved sites on a proper frost-protected slab, with a budget that can't reach a cantilever
- Temporary or seasonal enclosures that are removed before winter
What We Install Instead
For nearly every Winnipeg driveway, yard or compound, the answer is a cantilever slide gate: the panel hangs from rollers on its own posts and never touches the ground, so snow, ice and heave don't matter. Where the fence line is too short for a cantilever, an overhead track gate keeps the rail up on a beam instead of in the ground. Both cost more than a bottom track gate on day one and less by the third winter.
If you already have a bottom track gate that's fighting you, we can often reuse the posts and operator and convert the opening to cantilever. Ask us for a site look.
