UV Printed Hollow Sheet for Coroplast Signs and Custom Printed Boards
UV printed hollow sheet is a printable PP hollow sheet, also called printed coroplast sheet, printed corrugated plastic sheet or printed corflute board. It is used for advertising signs, yard signs, event boards, directional signs, display panels, construction warning boards and custom printed packaging sheets.
Jinmai can supply printable PP hollow sheets in common thicknesses such as 4mm, 6mm and 10mm. For outdoor yard signs and temporary display boards, we can also provide matching H stakes / H stands as accessories.
What Is UV Printed Hollow Sheet?
UV printed hollow sheet is made by printing text, logos, graphics or warning information on PP hollow sheet. The hollow fluted structure keeps the board lightweight, while the printed surface helps buyers use it for promotion, identification, direction, safety notice or branded packaging.
Main Applications
- Yard signs and H-stake signs: real estate signs, election signs, campaign signs and outdoor temporary signs.
- Advertising and promotion: event signs, retail display boards, exhibition panels and directional boards.
- Construction and safety: warning boards, site notice boards, floor/wall protection signs and temporary instruction boards.
- Packaging and logistics: printed divider sheets, labeled layer pads, turnover box panels and reusable identification boards.
- Agriculture and outdoor use: plant labels, farm signs, temporary boards and moisture-resistant markers.
Common Thickness Options
| Thickness | Typical Use | Buyer Notes |
|---|---|---|
| 4mm | Yard signs, election signs, real estate signs, event signs | Lightweight, easy to insert with H stakes, suitable for temporary outdoor display |
| 6mm | Stronger signs, display boards, packaging panels, reusable boards | Better stiffness than 4mm for larger boards or repeated handling |
| 10mm | Heavy-duty display boards, protection panels, thicker packaging sheets | Used when higher rigidity, durability or stronger support is required |
H Stakes / H Stands for Yard Signs
For outdoor yard signs, H stakes are commonly used with 4mm corrugated plastic signs. The wire stake is inserted into the flute direction of the hollow sheet, allowing the sign to stand on grass, soil or soft ground. When ordering signs with H stakes, buyers should confirm board size, flute direction, sign quantity and whether the H stakes need to be packed together with the printed boards.
Printing and Customization Options
- Single-sided or double-sided printing
- Custom logo, text, QR code, warning message or full-color graphic
- Custom board size and shape
- 4mm, 6mm and 10mm thickness options
- White or colored PP hollow sheet base material
- Optional hole punching, cutting, creasing, edge finishing or H stake matching
How to Choose the Right Printed Hollow Sheet
If the product is used as a temporary yard sign, 4mm printed coroplast with H stakes is usually a practical choice. If the board is larger, handled repeatedly or used as a packaging panel, 6mm may provide better stiffness. If the application needs stronger rigidity or protection, 10mm can be considered. Buyers should also confirm whether the sign will be used indoors, outdoors, on soft ground, on a wall, or inside a packaging system.
Artwork and Quotation Checklist
To request a quotation, buyers can provide the board size, thickness, quantity, printing side, artwork file, color requirement, indoor/outdoor use, H stake requirement, packing method and shipping destination. For printed signs, vector artwork or high-resolution files are recommended for clearer printing results.

Can you print double-sided full-color graphics and supply matching H stakes?
Yes. Single-sided or double-sided custom printing can be specified, including full-color graphics, and matching H stakes can be supplied for yard-sign applications. Confirm board size, quantity, flute direction and whether the stakes should be packed together with the printed boards.
