Shipping/cargo containers are much stronger than traditional wood light frame construction, this is simply because shipping containers are made from steel, which is much stronger than wood.
Many are designed to be stacked eight or nine units high. Steel shipping/cargo containers walls are made from 14 gauge, 0.075 inch corrugated sheet steel panels that are welded to the main structure. The top and bottom side rails and end frames are 7 gauge tubular steel. The steel used to build modern shipping/cargo container is a corrosive resistant high-strength low-alloy steel.
The roof of shipping/cargo containers is constructed with die-stamp corrugated steel sheets with a certain chamber at the center. The roof’s main purpose is to keep out the elements.
The bottom of the shipping/cargo container has 3-4 mm thick cross members that have recesses along the bottom side rails, which allows them to be lifted with special straddle carriers. The floor of the shipping/cargo container is 28 mm thick with 19 ply treated plywood screwed into the structural cross members.
Shipping containers can resist snow, wind, hurricanes, tornadoes and earthquakes. Please contact us at www.structure1.com or (541) 850-6300 to check your local conditions.
