Automated commercial gates are everywhere—warehouses, parking garages, factories, loading docks. You hit the button (or the sensor picks up your truck), and the thing slides or swings open like it’s no big deal. But when the weather decides to go nuts—either baking hot or freezing your ass off—those gates can turn into a real pain in the neck. They jam, slow down, stop working altogether, or just wear out way faster than they should.
Look, nobody wants to deal with a gate that refuses to budge when deliveries are waiting or employees are trying to get in/out during a rush. Here’s the straight talk on how extreme temps screw with these systems and what actually helps keep them from crapping out.

When It’s Stupid Hot Outside
Heat doesn’t just make you sweat; it messes with the metal, the grease, the electronics, everything.
If your commercial gate is already giving you trouble in extreme heat or cold, Zimmer Gates and Doors provides professional commercial gate solutions, service, and support designed for heavy-duty, real-world conditions.
Metal parts expand when they get hot. That sliding gate rail or swing arm that’s been perfectly aligned all year? In 40°C+ (100°F+) weather, it swells just enough to throw things off. Rollers bind, the gate grinds, motors strain harder. I’ve seen setups where the gate starts making this awful scraping noise like nails on a chalkboard because the track’s no longer straight.
Motors and control boxes hate getting cooked too. They’re usually in metal housings that turn into little ovens in direct sun. Overheat protection kicks in and the whole system shuts down temporarily to save itself—great for the hardware, shitty for your schedule. Batteries (especially lead-acid ones in solar or backup setups) die quicker in heat; every 8–10 degrees hotter can cut their life in half.
Lubricants dry out fast. That grease you slapped on last winter? In summer scorchers it basically evaporates or thins out, so moving parts rub metal-on-metal and wear out quicker.
Real-world fix stuff: Shade the motor box if you can—even a simple awning or just parking a truck nearby helps. Use high-temp grease rated for hot conditions. Check alignment more often during summer. And don’t run the gate nonstop during peak heat if you can avoid it; give the motor breaks.
When It’s Freezing Your Balls Off
Cold is brutal in a different way. Everything contracts, stiffens, or straight-up freezes.
Ice builds up on tracks, rollers, hinges. One good freeze and your sliding gate is glued to the ground. Swing gates get ice in the pivots and won’t budge. Sensors get frosted over and think something’s always in the way, so the gate reverses constantly or won’t close.
Lube thickens like molasses. Normal grease turns to tar in sub-zero temps, making the motor fight twice as hard. Hydraulic systems (if you’ve got ’em) get sluggish because the fluid gets viscous.
Batteries lose power fast—cold kills capacity, sometimes dropping 50% or more below freezing. Electronics can get brittle wires or condensation that shorts things out.
Motors strain, overheat from working too hard against the resistance, and burn out if you’re not careful.
Practical shit that works: Switch to cold-rated lubricant before winter hits—silicone-based or special winter grease that stays movable. Clear snow/ice off tracks and arms every time it storms. Add heaters to the motor housing or battery if you’re in a really cold spot (some commercial kits have bolt-on ones). Insulate control boxes. Keep batteries charged and maybe wrap ’em or use cold-weather ones.
Bottom Line + Quick Tips to Not Get Screwed
Extreme heat expands stuff, dries lube, cooks electronics. Extreme cold shrinks stuff, freezes mechanisms, kills batteries, thickens fluids.
Most breakdowns aren’t some mystery—they’re temperature-related wear that builds up until something snaps.
To keep your gate from turning into an expensive paperweight:
● Lubricate twice a year with the right stuff for your season.
● Inspect tracks, rollers, arms for wear/alignment every few months.
● Shade or ventilate motor boxes in hot areas.
● Clear ice/snow immediately in winter.
● Test backup batteries regularly.
● Get a pro service once a year—catch small shit before it becomes a weekend disaster.
These gates are tough, but they’re not invincible. A little preventive hassle now saves you from standing in -10°C rain waiting for a tech who can’t get there till Monday.
If your gate’s already acting up in weird weather, nine times out of ten it’s one of these temperature gremlins. Fix the basics and it’ll probably behave again.
