20ft Flat Rack Container
A reinforced floor with end walls — for over-width and over-weight pieces
The 20ft flat rack is essentially a heavy-duty steel platform with fixed or collapsible end walls and no roof or side walls. Its reinforced floor takes concentrated loads far beyond a dry box, making it the unit of choice for compact, very heavy machinery, and for cargo wider than a container.

Typical cargo & use cases
- Compact heavy machinery: presses, transformers, generators
- Over-width cargo (loaded across two adjacent slots)
- Boats, vehicles and steel coils with special cradles
Loading tips
- Engineering drawings and a lashing plan are usually mandatory — prepare them before booking.
- Concentrated loads need load-spreading beams sized by the cargo's footprint.
- Weather protection is on you — shrink-wrap or tarp anything sensitive.
Frequently asked questions
- How much weight can a 20ft flat rack take?
- Typical units are rated around 30–34 t gross with ~31 t payload — noticeably more than a 20ft dry box, and higher-rated specials exist for project cargo.
- What does out-of-gauge (OOG) mean on a flat rack?
- Cargo exceeding the container envelope in width or height. It blocks adjacent/above slots, so carriers charge for the lost slots — often the dominant cost of the shipment.
