We make a lot of custom planters including round and triangular shapes.
These have many options:
Stainless steel casters/wheels that can have brakes.
Storage covers that can be removed or with stainless steel hinges dampeners = reverse shock absorbers (think of a hood or hatchback on a car) so that fingers do not get pinched
Decking caulk (the same stuff used on decks of yachts) on the horizontal top so they are waterproof)
Description
Asphalt liners to make them last longer
Thick plastic to make them waterproof
Copper or stainless steel screening with gaps for air circulation for storage (pillows, dog and cat food, gardening tools and supplies, etc.) so that rodents and insects cannot get into the boxes
Faucet on the bottom to allow for drainage when you want
etc.
We can put just about any bell or whistle on your box and even paint these!
