Container Types Overview
Every twistlock and lashing fitting is chosen to match a container — so before picking hardware, know the box: its dimensions, its door opening and what it's rated to carry.
Corner castings sit at the same ISO 1161 positions on every Series 1 container, whatever the type — general-purpose, reefer, open-top or flat-rack. That consistency is what lets one range of twistlocks, lashing points and lifting hardware serve dry boxes, reefers and flat racks alike, and it's why this reference starts with the container itself: external dimensions, internal dimensions, door openings, and tare, gross and payload weights for each of the standard ISO series-1 types.
These figures are drawn from carrier and industry reference specifications. Individual units vary by manufacturer and age, so the CSC (Convention for Safe Containers) plate riveted to the actual container is always the final word for that specific unit.
Use this section when you need to know about the container itself — its dimensions, door openings and rated weights — rather than a specific piece of hardware.
Scope: this reference covers the container types our hardware most commonly interfaces with. Bulk/hopper, half-height and open-side types fall outside it. Tank containers are included for reference only — we do not supply the tank itself — and they vary more by cargo class than other types do: general chemical and food-grade T11 tanks are shown here, while pressurised gas tanks in the T50 series carry materially different tare and gross weights.
