We manufacture our own basketball backboards in-house.
Matchplay boards are made from 24mm thick birch-faced plywood and are painted using resilient chip and flake-resistant paint.
These boards will give you years of trouble-free usage.
Please be aware of alternative boards made from MDF or with tape to mark the border and shooting box. Those boards look great when you get them, but MDF is not resilient enough to deal with the impact of basketball goals (especially at the corners and edges). It is well worth paying for a high-specification laminated timber board such as this - anything else is false economy.
The board is supplied un-drilled so you will need to drill the board to suit your ring and mounting.
