What Is a 40-Foot Insulated Shipping Container?
A 40-foot insulated container is a steel shipping unit equipped with thermal insulation built into the walls, roof, and floor. Unlike standard shipping containers, it’s designed to maintain a stable internal temperature regardless of external conditions.
Key Specifications:
