Shipping Container Having Fiberglass Frame

Abstract

A fiberglass frame for a shipping container supports dunnage or other support members for separating parts. The fiberglass frame comprises four hollow vertical edge members made of fiberglass, each extending between corner assemblies. The fiberglass frame further comprises a roof and a base each made of hollow fiberglass members. Each hollow fiberglass member extends between two corner assemblies. The corner assemblies are also made of fiberglass. The inherent lack of electrical conductivity in the frame prevents sensitive parts shipped in the dunnage or other support members from being damaged or compromised.
