SandCastle Developers can tell you that the Fiberglass Composite materials are stronger than wood, steel, and concrete. The Fiberglass material can withstand high winds and it doesn't pollute our environment. Plus, it last more than 100 years. All materials are made in the USA. Why use materials that start deteriorating on installation? This is not cost effective.
