Shipping container conversions continue to grow in popularity across storage, retail, and industrial sectors. However, many buyers feel confused by industry terms. Understanding key language helps you plan better for the container conversion you need and avoid costly mistakes.
Below are five commonly used terms in container conversions, explained clearly and simply.
1. One Trip Container
A one trip container completes only one cargo journey before delivery. As a result, it arrives in near-new condition. When people refer to “new” shipping containers, they usually mean one trip containers.
Most shipping container conversions start with one trip containers because they offer clean interiors, solid marine-grade floors, and minimal wear. They also reduce repair work, speed up the build process, and improve finish quality. Therefore, one trip containers deliver better long-term value for shipping container conversions.
2. High Cube Container
A high cube container provides extra internal height. This extra space can improve the depth of insulation.
Many container conversions use high cube containers for workshops and storage. The extra height supports electrics and ducting.
As a result, high cube containers allow more usable space and easier fit-out during shipping container conversions.
3. Bunded Floor

A bunded floor includes a raised containment edge designed to control liquid spills. This feature protects surrounding areas of the shipping container and helps meet environmental and safety regulations.
Many industrial container conversions require bunded floors for chemical or fuel storage. The smooth surface also allows fast and easy cleaning in case of spills, keeping the container safe and operational. Therefore, bunded floors are ideal for chemical, fuel and hazardous-material storage shipping container conversions.

4. RAL Colour



RAL colours provide standard colour options. For example, RAL 5010 creates a bold blue finish. RAL 9003 delivers a clean white look.
Clients often require their container conversion to match their company’s branding.
This Indoor Farming Container, clothing store, and pop up bar for festivals are some of Lion’s most eye-catching branded container conversions.
Even where branding is not a priority, the correct RAL colour provides Lion customers with smart-looking container conversions which compliment their surroundings.
The most popular RAL colours chosen by Lion customers include RAL 5010 Blue, RAL 6007 Green, RAL 7037 Grey, RAL 9003 White and RAL 7016 Anthracite Grey.
5. Fire Rated Lining
Fire rated lining slows fire spread and improves safety.
Many container conversions include 30-minute fire ratings. This feature suits chemical storage and equipment housing.
Fire rated lining adds protection to more high-risk shipping container conversions.
