About Deck Railing
All decks higher than 24" above grade must have a guardrail. There's no nice way to put it, having a deck without railings is an extreme danger since any person can fall from it. By installing deck railings, homeowners can prevent these falling incidents from happening.
On the other hand, railings give the deck a unique personality. You are welcome to choose any high quality materials you prefer and combine them in different variations: wood, composite, aluminum,glass etc.
