PP Hollow Sheet (Blue Hollow Board)

PP hollow sheet is a lightweight polypropylene board made of two flat skins joined by ribs, which leaves hollow channels inside. Site teams call it blue sheet or PP hollow board and use it to cover floors and finished surfaces, and to make partitions and boxes. Falcon Link TR supplies PP hollow sheet from Sharjah in 2 to 12 mm thickness.

What is PP hollow sheet and how is it built?

The board is extruded from polypropylene in one piece. A top skin and a bottom skin are tied together by thin vertical ribs. Seen from the cut edge, the hollow cells run in straight lines along the sheet. Our catalogue describes the section as H-shaped hollow, which is the rib pattern that gives the board its stiffness without much weight.

Because most of the volume is air, the sheet is light to carry and easy to cut with a sharp knife. Polypropylene does not absorb water, so the board does not swell, rot or go soft when it is washed or left in a damp area. Buyers also search for it as twin wall PP sheet, polypropylene hollow sheet or PP hollow board. In the UAE it is often called by the same names as corrugated plastic, such as correx or coroplast.

PP hollow sheet sizes and thickness: what to ask for

The blue sheet in our catalogue is 0.90 x 2.00 m, so one sheet covers 1.8 square metres. Thickness runs from 2 mm to 12 mm. Pick the thickness by the job, not by habit.

The table gives typical trade use. Confirm exact size, thickness and quantity with our sales team, because the figures depend on the supplier lot.

PP hollow sheet vs corrugated, solid and honeycomb board

These names get mixed up on enquiries. The table shows how they differ so you order the right material.

In short: if you need a flat, light board that cuts easily, choose hollow sheet. If the floor will carry trolleys or tools, ask about honeycomb. If you want a clear or glazed panel, you need polycarbonate sheets, not PP.

Where is PP hollow board used?

Why choose PP hollow sheet over plywood or cardboard?

• Water does not hurt it. Cardboard collapses when wet. Plywood swells at the edges. PP can be wiped and reused.
• Easy to carry up stairs. A 0.90 x 2.00 m sheet is light, which matters on floor-by-floor jobs without a goods lift.
• Clean to the surface. A smooth skin will not drag grit across marble the way a rough board can.
• Quick to shape. It cuts with a knife, can be taped, and can be creased along the ribs.
• Reusable across jobs. Careful crews lift the sheets, clean them and use them again on the next floor.

How do you choose the right PP hollow sheet?

1. Decide the job: surface cover, partition, packing or display.
2. Match thickness to the load. Foot traffic only needs 3 mm. Trolleys and ladders need more.
3. Count sheets from area: area in square metres divided by 1.8, then add a margin for overlaps and cuts.
4. Check the colour. Blue is the catalogue colour.
5. Ask whether you need full sheets or cut-to-size pieces.

Common mistakes: ordering 2 mm for a corridor that will see pallet jacks, laying the sheet over wet tiles and trapping moisture, and leaving it on a hot slab with unsealed edges so it curls. In UAE summer, sheets left in direct sun can warp and fade. Store them flat, in the shade, and tape the joints once they are laid.

What to buy together with PP hollow sheet

Most buyers also need tape to hold the sheets, such as masking tape for edges or duct tape for joints. For wet work, lay polythene roll under or over the board. For a full cover system, read our floor protection sheet page and the wider polypropylene sheet range.
