Best for

Modern designs, ocean-front or salt-air installs, contractors wanting fastest install (most kits go up in 1/3 the time of wood), 2nd-floor decks where weight matters.

Watch-outs

Powder-coat finish can chip and show silver underneath at impact points (hot tubs, pool ladders) — touch-up paint required. Limited color range (black, bronze, white, sand mostly).
