FRP Grating
FRP Tree Grates
FRP tree grates are molded fiberglass panels installed around tree pits in sidewalks, parks, plazas and street landscaping projects. They help water and air reach the root area, reduce handling weight compared with many metal grates, and can be supplied in project colors. Buyers should confirm tree pit size, panel layout, center opening, thickness, mesh, resin, surface, support frame and quantity before quotation.
Files PDF, DWG, DXF, sketches and product photos are welcome.
Buyer overview
FRP Tree Grates Are Specified by Tree Pit Opening, Panel Layout and Outdoor Exposure
Quotation should confirm tree pit opening, panel layout, center cutout, support ledge or frame, pedestrian load, thickness, mesh size, resin, color, anti-slip surface and packing marks.
QY Metal Tech reviews landscaping drawings, marked photos, tree opening dimensions, color requirement, quantity and export packing notes so the tree grate quotation matches the installation area.
Tree pit layout
Square, rectangular or custom panel layout should match the support ledge and installation opening.
Center opening
Tree trunk clearance, opening diameter or custom cutout shape should be confirmed.
Thickness and mesh
Thickness and mesh size depend on pedestrian load, drainage needs and support frame.
Resin and color
Resin system and color should match UV exposure, outdoor service and landscape appearance.
Surface and fixing
Gritted surface, removable layout, clips or edge fit can be reviewed for pedestrian areas.

Design notes
Send Tree Pit Dimensions, Support Frame and Color Details
Panel size, center opening, split direction, support ledge, surface and color usually decide whether the quotation can be prepared quickly.
For replacement tree pits, site photos and old panel measurements are useful when a full landscaping drawing is not available.
Standards reference
FRP Tree Grate Standards and Outdoor Surface References
- FRP tree grate selection can be reviewed by thickness, mesh size, resin system, surface, color, support frame and landscaping drawings.
- Fire, resin and mechanical property references such as ASTM E84, ASTM D635 or ASTM D2583 can be discussed when required by the project.
- Public pedestrian areas should confirm anti-slip surface, UV exposure, drainage, removable panel layout and local access requirements.
- Final specification should follow approved tree pit drawings, support frame details, operating environment and buyer approval documents.

Applications
Where FRP Tree Grates Are Commonly Used
Sidewalk tree pits
FRP tree grates for sidewalks, parks, plazas and public pedestrian areas.
Drainage and root airflow
Open mesh helps water and air flow around the tree base while keeping the walking area covered.
Streetscape replacement
Lightweight FRP panels can replace old or corroded grates with project color and panel marks.

Project notes
Confirm Tree Pit Layout, Color and Packing Before Production
For project supply, FRP tree grates should be checked against the landscaping drawing, support ledge, center opening and installation area before production.
Clear panel marks, split-panel sequence, color requirement and packing notes reduce revision time and help installers match each tree pit.

FAQ
Common FRP Tree Grates Questions
Why choose FRP tree grates?
They are lighter than many metal grates, do not rust and their open mesh lets water and air reach the roots while keeping the walking area covered.
Can the center opening be customized?
Yes. Trunk clearance, opening diameter or a custom cutout shape can follow your drawing or a marked site photo.
Can tree grates be split for existing trees?
Yes. Two-piece or multi-piece layouts let panels be installed around trees that are already planted.
Which colors are available?
Green, yellow or a project-specified color, confirmed together with the resin system and outdoor UV exposure.
What panel type is used for public walkways?
A 38 × 38 × 38 mm molded panel with gritted anti-slip surface is a common choice for pedestrian tree pits.
For a walking route, confirm the finished clear openings and the applicable accessibility requirements with the project designer; a nominal mesh size is not an accessibility approval. See our guide to mesh pitch and clear openings.
Can FRP tree grates replace old metal grates?
Yes. Send site photos and the old grate and pit dimensions so the new panels match the existing support ledge or frame.
