I am involved in providing a community notice board and have the following
requirements:

1 Vandal resistant
2 Weatherproof materials
3 Easy to insert drawing pins

1 is being addressed by using a welded steel frame, bolted to a wall,
using hidden (or tamperproof) bolts

2 means basically the material should be rainwater resistant (will not
rot easily)

3 is the killer; people need to be able to press in drawing pins fairly
easily but the pins must hold the notices securely, and the pins must be
fairly easy to remove later.

Can anyone suggest the ideal material for the board? MDF is too hard.

Martensitic (400 series) stainless steel, or cheaper plastic coated mild
steel, using small, powerful magnets instead of drawing pins.
