Cangzhou Shengtai Metal Products Co., Ltd. produces cast iron tree grates, also known as tree pit grates or tree guards. These are grid-like covers used to cover tree pits in urban greening. These grates are corrosion-resistant, lightweight, high-strength, easy to cut and install, age-resistant, flame-retardant, safe, customizable in color, economical, and highly designable.

They protect tree roots, preventing damage from pedestrians and vehicles, and reducing soil compaction. Their porous structure ensures smooth ingress of rainwater and air. They also prevent debris such as leaves and plastic bags from falling into the tree pits, keeping the ground clean. Through their diverse materials and designs, they enhance the landscape.
