Before you pick it up

Two people per piece. 90 lb each. Awkward as well as heavy: a wide panel has no good handhold, so it is heavier to carry than the number suggests.

The whole load. All 180 lb of it. Worth checking against what the car is rated to carry before you drive to the yard, and worth knowing before a freight quote.

Before you drill. The shelf itself is 90 lb before anything goes on it. Size the hardware for the shelf plus its load, fix into framing rather than drywall anchors wherever the two disagree, and remember that a floating shelf loads its bracket as a lever — the further out the weight sits, the harder it pulls at the wall.

Particleboard

Cheap, heavy and allergic to water. Fine for a shop jig or a shelf that stays dry, a poor idea anywhere it can get damp — a wet edge swells and never comes back.
