Why Two-Color HDPE for Play Panels
- Zero paint, vivid graphics — Engrave 0.6–1.0 mm and the core color shows cleanly.
- Outdoor durable — UV-stabilized grades resist fading and chalking; no splinters, no rot, no rust.
- Child-safe edges — Easy to radius/chamfer; rounded corners and deburred edges are simple to finish.
- Low upkeep — Wash with mild soap; graffiti can be removed with approved cleaners (spot test first).
Recommended Specs (Playground Panels)
| Item | Our Recommendation | Notes |
|---|---|---|

| Thickness | 12 mm main panels; 10 mm small inserts; 6–8 mm decorative overlays | Go 15 mm for large spans or heavy use |
| Layer Build | Cap / Core / Cap | Top cap 0.3–0.6 mm typical |
| Material | HDPE (UV-stabilized option) | Black, natural or custom colors |
| Surface | Matte / Orange-peel | Anti-graffiti protective film optional |
| Thickness Tolerance | ±0.2–0.5 mm | Confirm per gauge in PO |
| Flatness | <2 mm/m (typ.) | Measured on granite |
| UV & Color | Outdoor grade, 20+ color combos | Pantone match with MOQ |
| MOQ & Lead Time | 30–50 sheets / color; 7–15 days | By color & volume |
Typical Weight (4×8 ft)
For logistics planning, a 4×8 sheet weighs approximately:
| Thickness | Weight / Sheet |
|---|---|
| 10 mm | ≈28.3 kg |
| 12 mm | ≈33.9 kg |
| 15 mm | ≈42.4 kg |
Calculated with area 2.9768 m² and density ≈0.95 g/cm³; actual weight varies with tolerance/density.
Design & Fastening (Thermal Expansion Matters)
- Expansion allowance — HDPE moves ≈0.18–0.20 mm per meter per °C (≈5–6 mm/m across a 30 °C swing). Use slotted holes and floating washers.
- Hole sizing — Slot length ≈ screw dia. + expected movement; keep edge distance ≥ 2× thickness.
- Fasteners — Stainless steel screws/bolts with large OD washers or bushings; avoid hard-clamping wide panels.
- Spacing — Perimeter 200–300 mm; field 300–400 mm (typ.), adjust for panel size and wind loads.
- Edges — Radius R2–R4 mm or 45° chamfer; deburr to child-safe finish.
Engraving & Graphics
- Depth — 0.6–1.0 mm to fully expose the core color without revealing the back cap.
- Tools — V-bit 60°/90° or flat 1/8″; sharp cutters + chip evacuation to prevent melting.
- Fonts & icons — Avoid ultra-thin strokes; keep minimum line width ≥0.8–1.0 mm for outdoor readability.
Safety & Compliance Notes
Our panels are material components. Final playground equipment must be engineered and installed to local standards (e.g., ASTM F1487 / EN 1176) by qualified parties. We can provide material COA, RoHS/REACH statements, and color/UV documentation upon request.
Cleaning & Maintenance
- Routine wash with mild soap and water; soft cloth or sponge.
- For graffiti, test cleaners on a small area; avoid aggressive solvents that may haze the surface.
- Inspect fasteners seasonally and re-torque as needed (accounting for thermal movement).

FAQ
What thickness do you recommend for main playground panels?
We recommend 12 mm for most main panels. Use 10 mm for small inserts and 15 mm for large spans or heavy-use areas.
Will the colors fade outdoors?
We offer UV-stabilized grades for outdoor use. Actual color change depends on climate and exposure; we can share our color management and ΔE controls.
Can you pre-drill and round all edges?
Yes. Provide drawings; we’ll deliver panels with rounded corners, radius/chamfer edges, and drilled/slot holes ready to install.
Do you provide safety certifications?
We provide material documentation (COA, RoHS/REACH). The finished structure must be certified to local playground standards by the equipment maker/installer.
