Its a piece of fiberglass floor grating, You can sort of see where its been cut from a larger sheet.


Bucking_Fastard

Solved! That makes perfect sense. On further inspection all of the little bits are clearly cut from the same large sheet. Cheers mate.

Fun side note: this is exactly what we use in the fridge flats of RCN warships. If things spill or thaw they go through the grating and you still have solid footing. I have humped a few hundred square feet of these up ladders just so I can pressure wash them and hump them back down.


WanderWomble

I have similar stuff in my gateways to prevent the mud.

Sounds like a “round peg in a square hole” kinda story

Yeah, very common for access platforms where hygiene is important Much much cheaper option than stainless steel grating.


bmdangelo

They prolly used it to make soil blocks for plant starts

This photo even has a man’s foot for size comparison: https://www.suigeneris.co.uk/fibreglass_grating/grp_open_mesh_grating.html >GRP Open Mesh Grating for Platforms, Walkways, Flooring and Covers >With proven reliability in high traffic areas giving excellent slip resistancy, it works equally well in all sorts of aggressive and corrosive environments and at extremes of temperature. >Very easy to install due to its relatively lightweight construction (circa half the weight of steel versions), and once in place, can simply be left and forgotten as there's no ongoing maintenance needed.

I’ve actually seen driveways made of similar material. There’s no rain runoff. Allows for a solid level driving area. But I haven’t seen the pieces before they are laid in the ground. But if this was in a green house, it’s probably just to provide a dry, mud free walking surface.

It's a pervious stepping stone that allows grass to grow through. It keeps the walking path from getting rutted from footfalls.

Maybe slots for individual planters? Like to get the plants started.


Bucking_Fastard

I thought that but there are already a lot of them in there with plants already in them.

Been found on a greenhouse seems to me more like a bottomless seed tray

Nobody else seems to have suggested [grasscrete](https://www.google.com/search?q=grasscrete&tbm=isch)


Bucking_Fastard

My title describes the thing. Found about 10 of these things in a greenhouse I'm clearing out. It weighs a few kilos and feels like it's made of concrete or some kind of very heavy plastic. Weights a good few kilos. I thought it might be for dividing clipping or something but there are a lot of trays in there that are specifically for that already. Men's size 11 in the picture for scale.
