Every broom Keystone ships is manufactured from the ground up, starting with the bristle. It’s the part of the broom that actually touches the road, and it’s where over 80 years of manufacturing expertise shows up most clearly.
The bristle is where performance lives.
A broom is only as good as its fill, and getting that right isn’t simple. Too stiff and you risk damaging surfaces; too soft and debris gets left behind. That’s why we don’t source our bristle — we engineer it. Our polypropylene filament is built to deliver excellent stiffness, flexible flicking action, and good bend recovery, so the broom continues to perform whether it’s on the first pass or the one-thousandth. It’s also resistant to most solvents, oils, chemicals, acids, and bases, because we know real-world sweeping environments don’t give you ideal conditions.
Why it matters to your operation.
When you’re running a fleet, the price of a replacement broom is only the beginning of the story. Sweeper downtime and the labor involved in a changeover can easily add up to more than the broom itself, which means the quality of the bristle has a direct impact on your bottom line. A broom built on the right filament lasts longer, sweeps cleaner, and needs to be changed less often — and that adds up to real savings across every route, in every season.
It’s why OEM manufacturers, municipalities, and contractors have trusted Keystone for over 80 years. Quality that holds up in the field isn’t an accident — it starts with the bristle.
