What is the difference between fixed and collapsible flat racks?

Fixed flat racks have permanent end walls providing more security for heavy cargo. Collapsible flat racks have folding end walls, allowing 4-5 units to stack together when empty, reducing repositioning costs.

How much does it cost to ship a flat rack container?

Flat rack shipping typically costs 2-4x more than standard containers due to special handling requirements and OOG surcharges. Exact pricing depends on dimensions, weight, route, and cargo overhang.

Can cargo hang over the sides of a flat rack?

Yes, cargo can overhang the sides (out-of-gauge), but this incurs additional charges. Each carrier has specific limits on overhang dimensions. Significant overhang may require booking multiple container slots.

Overview

Flat rack containers are essential equipment for shipping oversized cargo that exceeds the dimensions of standard containers. With no side walls and collapsible or fixed end walls, flat racks allow cargo to extend beyond the container's footprint. They're commonly used for heavy machinery, vehicles, boats, industrial equipment, and construction materials. Available in 20ft and 40ft sizes, flat racks can be loaded from the top or sides using cranes or forklifts.
