Alberta & Ontario
Solid recycled HDPE for decks, docks, boardwalks and fences. It won't rot, splinter or needs sealing. And we'll price your package within one business day.
Why it lasts
Our biggest line
Most of the plastic lumber that leaves our yard becomes a deck. Just tell us how big your deck is and we'll count every board and screw it takes, and price the lot.
A sketch, a plan or measurements. Include whatever you have with your quote request
Board count, fasteners and a cut layout worked out so the joints land on joists, not mid-span.
Priced and ready for pickup, or delivered anywhere in Alberta and Ontario.
Beyond decking
Your wettest, dirtiest, hardest-to-reach jobs are where this board earns its keep. Ground contact, standing water, livestock country. Send the dimensions and the takeoff works exactly the same way.
Tables and benches that sit in wet ground all season. No sanding, no sealing, no annual refinish
Pens, bunks and fences that shrug off manure, moisture and pressure-washing season after season.
The strongest case for plastic lumber. Boards sit submerged, freeze solid and bake in the sun, without warping or swelling.
In partnership
Together with Premium Built Structures, we make the Eco Column: a solid recycled HDPE post frame foundation that keeps structural wood out of the dirt.
Alberta Emerald Awards · 2026
Judge's Choice Award recipient. Eco Column took the Judge's Choice at the 35th Annual Emerald Awards in Calgary, awarded jointly to Grey is Green and Premium Built Structures for turning hard-to-recycle plastic into post-frame foundations. Read the citation.
Built with Premium Built Structures
The Eco Column is a recycled HDPE foundation column for post frame shops, barns and riding arenas, developed in partnership with Premium Built Structures.
A different product from our dimensional lumber, engineered and tested to carry load. Ask us which one your build needs.
From waste to board
Paint pails in, lumber out. Ours comes from the plastics almost nobody will take (used oil containers and paint pails, dirty and mixed and worth nothing to anyone else) collected through Canada's regulated programmes and extruded into solid board at our own plant.
Stage 01
Paint and oil pails recovered through regulated Canadian recycling programs.
Stage 02
Cleaned and ground to flake. Mixed colours go in together, which is where the grey comes from.
Stage 03
Melted and formed into solid dimensional boards. No wood fibre, no chemical treatment.
Stage 04
Solid through the section. Cut it, drill it and fasten it with ordinary tools.
Our impact
Buying the board is what pulls the plastic out of the waste stream. Canadians bin roughly three million tonnes a year and recycle under a tenth of it, and pails sit at the difficult end of that: too contaminated for most processors, too cheap to be worth cleaning.
Updated monthly
0lbs
diverted since January, and rising every week we run the line.
We issue a diversion statement for any project, showing the weight kept out of landfill by your order. Councils put them in committee reports; builders put them on site boards.
Request a statement
Put in your dimensions. We'll show you the weight of plastic your build keeps out of landfill, and issue it as a statement you can hand to a client or a council.
Estimate based on 2×6 boards at 8 ft
Your project would divert
612lbs
of plastic that would otherwise have gone to landfill.
Send the dimensions and we'll come back with the whole thing counted, laid out and priced, usually within one business day.

When we set out to manufacture portable Miniature Golf we needed material that was durable, long lasting and fit the look and vision we wanted. Grey is Green checked absolutely every box! They are now more than just our supplier, they are friends that have gone over and above for us time and time again. From the material itself to the team behind it, we look forward to working with Grey is Green for many years to come!
The question to ask myself was not if I should, but when I should replace my decking with the recycled plastic decking. The end result has turned out beautifully and I will never have to redo this deck again. Longevity and durability are the key factors. One power wash and it's clean as a whistle. I would highly recommend.
