Product Q&A

Q:Square flat grate vs side entry kerb grate

Square grate matches square cast-in-place tree pits, neat pavement layout, more popular for municipal standard greening; round grate fits circular tree pits, uniform stress distribution, mostly used for scenic boutique landscapes.

Q:QT500-7 vs FRP tree pit grate

FRP light weight but poor impact resistance, easy aging crack under ultraviolet sun; QT500-7 ductile iron high toughness, anti-aging, service life 3x longer, stable for heavy pedestrian flow roads.

Q:Split 4-piece vs integral one-piece structure

Integral whole piece only suitable for newly planted small saplings; 4-split mandatory for mature large trees, convenient wrapping around thick trunks.
