Great question! It’s one we hear a lot from cities in northern climates, ski resorts, and even coastal towns that get hit with sudden cold snaps. The short answer is: we design our street benches with winter in mind, using materials and engineering that simply don’t behave like traditional wood or metal when temperatures plummet.
Let me break down the key reasons our benches stay intact when it’s freezing.
Material Selection is Everything
We avoid materials that absorb water. Traditional wood soaks up moisture, which then expands when it freezes, causing splits and cracks. Instead, our benches use high-density polyethylene (HDPE) — a recycled plastic lumber that has almost zero water absorption. Even after days of rain, snow, or slush, there’s no internal moisture to freeze and expand. Metals like iron or steel can become brittle and crack in extreme cold, but the steel we use is either galvanized and coated or replaced entirely with aluminum in the coldest regions, because aluminum retains flexibility at very low temperatures.
Thermal Contraction is Handled by Design
All materials shrink slightly when it’s cold. A poorly designed bench will fight that contraction, leading to stress fractures. Our benches feature expansion gaps in the slats and joints. These gaps are barely noticeable visually — just a few millimeters — but they give the material room to contract without putting pressure on fasteners or the frame. We also use stainless steel bolts and brackets that move differently than the HDPE, so one doesn’t crack the other.
No Water Traps, No Ice Explosions
If water gets into a small hole and freezes, it expands with tremendous force — enough to crack concrete. Our benches have sloped surfaces and open slats so that snow and rain run right off. There are no hidden crevices, cup holders, or flat screwholes where water can pool and freeze. The brackets are designed with drainage channels, and the legs are raised slightly from the ground to prevent ice from forming around the base and pushing upward.
Tested for Real-World Cold
We don’t just trust lab numbers. Each model is cold-impact tested at temperatures down to -40°F (-40°C). We freeze a bench solid, then drop a heavy bag of ice on it — simulating a person sitting down suddenly in extreme cold. If it cracks or shows stress, we revise the material mix or the design. Currently, our benches handle these tests with zero damage.
What About Snow Removal?
This is where a lot of benches fail. Snow plows, shovels, and salt can scratch or chip surfaces, leading to water intrusion later. Our HDPE surface is UV-stabilized and dense enough that it doesn’t chip easily, and salt has little effect on it. The steel hardware is galvanized or treated with a rust-proof layer. So even after heavy snow removal, the bench stays smooth and crack-free.
Real World Example
We have benches installed at a ski lodge in the Colorado Rockies where temperatures regularly drop to -30°F in January. The benches are completely exposed. After five winters, there’s not a single crack. The only maintenance needed has been a quick wash in the spring to remove road grime.
So, to give you a quick checklist:
- No water absorption → no freeze-thaw cracking
- Expansion gaps → thermal contraction isn’t a problem
- Drainage design → no ice pockets inside the bench
- Cold-tested to -40°F → proven performance
- Salt and impact resistant → survives snow removal
If you’d like, I can send you the specific material data sheet for any model you are considering. We can also discuss options like heated benches for extreme locations, though I’ve found most customers don’t need them with our standard design.
