Our home had metal cross braces that are corroded & we want to cross brace our stilts with wood. We have 6 ft centers going east & west & thougt 2x8s (16ft) crossing over 3 stilts would work. then the north south stilts are at 12' centers so wondered if we should go 2x10s. We are seeing newer constrution using 2x8s. We are on barrier island & get tropical storms & hurricanes so I want this old steel bracing replaced.
