Product Q&A

Q:Q1: Do water and debris fall through the gaps between teeth?

A: Gaps between interlocking teeth are minimal at the riding surface, and an optional EPDM strip beneath the teeth catches drips and blocks debris before it reaches piers and bearings below.

Q:Q2: How noisy is a finger joint compared to other types?

A: Steel-to-steel contact creates a mid-level hum, quieter than open finger designs but louder than rubber joints. Optional damping inserts reduce impact noise for residential areas.

Q:Q3: Can individual tooth plates be replaced if damaged?

A: Yes. Each plate is bolted independently -- a damaged tooth is swapped without removing the entire joint or cutting concrete.

Q:Q4: Does it work on curved or sloped bridge decks?

A: Yes. Tooth plates are CNC-cut to follow deck curvature and slope -- the comb profile adapts to alignment without extra components.

Q:Q5: How does it perform in snow and ice conditions?

A: Zinc-coated steel sheds ice better than rubber surfaces, and the flush profile resists snowplow blade damage. De-icing chemicals do not affect the coating.
