Our brooms start here...literally.

These two resin silos hold up to 360,000 lbs of raw material. The very foundation of every Keystone brush and broom that ends up in your hands.

They're looking good this spring after a fresh coat of paint!

From raw material to finished bristle, quality is built into every step of our process. It starts here.

Most people credit the broom when a sweeper performs well. We'd point to something a little more specific.

It's the bristle.

The part of the broom that actually touches the road. It's what lifts debris, flicks it clear, and resets for the next pass.

At Keystone, we don't source our bristle from a third-party supplier. We manufacture it ourselves, right here in the US. Controlling that process is how we control the quality that goes into every broom we ship.

After 80 years, we thought it was time to share a little more about where "Keystone Quality" actually comes from.

Is it time to replace your broom?

Here's a quick rule of thumb: measure bristle length from the tips to the core. Replace main brooms at 7 inches and gutter brooms at 6 inches.

Pro tip on down pressure: aim for a 2 - 4 inch sweeping path and let the bristle tips do the work. That alone can significantly extend broom life.

Small habits like these go a long way toward consistent performance and fewer surprise repairs.

Best kind of workdays include surprise visitors! At Keystone, family comes first — loved having Mike Santos's son stop by the office and brighten everyone’s day.
