When transporting out-of-gauge (OOG) machinery, heavy industrial equipment, structural steel, or oversized vehicles, standard enclosed shipping containers simply aren’t an option. Our 20ft collapsible flat rack containers deliver the structural integrity of an ISO chassis without side walls or roof restrictions, allowing fast top-loading and side-loading via crane or forklift.
At Shipping Storage Containers UK, we supply both new (one-trip) and high-grade used 20ft flat racks directly to construction firms, freight forwarders, agricultural suppliers, and industrial manufacturers across the United Kingdom.
Unlike fixed-end flat racks, collapsible models feature end walls that fold flush into the floor structure. This critical feature offers significant logistical advantages:

Manufactured using premium-grade Corten steel (corrosion-resistant alloy), our new 20ft flat racks have completed a single trip from the factory. They come equipped with fresh CSC plates valid for 5 years, pristine floor timber or steel decking, smooth spring-assisted folding mechanisms, and heavy-duty paint finishes designed for severe marine environments.
Our used collapsible flat racks are fully inspected by certified container surveyors prior to dispatch. While showing minor cosmetic surface rust or scuffs typical of marine freight service, every used unit is guaranteed Cargo Worthy (CW), structurally sound, with fully operational folding end walls, solid floors, and intact lashing points.
Securing heavy cargo is crucial during sea and road transport. Our 20ft flat rack containers feature multiple heavy-duty perimeter lashing rings embedded in the side rails and corner posts. Each lashing ring is tested and rated up to 5,000 kg (5 tonnes), allowing robust chain, strap, or wire tie-down configurations in compliance with international maritime safety codes.
