A 20-ft shipping container with side doors opens up the entire length of one side, so getting bulky or oversized items in and out is a breeze.
With about 1,200 cubic feet of space, it’s the perfect size for all kinds of storage needs, measuring 20 feet long, 8 feet wide, and 8.5 feet high.
It’s a favorite for industries like construction, events, and logistics, where fast, easy access really matters.
You can make it your own with upgrades like insulation, heavy-duty locks, or custom flooring.
Conexwest makes customization simple. If you’re thinking about windows, shelving, electrical work, HVAC, or even a branded exterior, we’ve got the tools and talent to make it happen.
Shipping containers have come a long way from just hauling cargo across oceans. The 20-ft version with side doors is a real standout because it opens up along the entire side, not just the back, making loading and unloading a whole lot easier.

Delivery typically costs between $500 and $1,000, depending on your location, and add-ons like insulation or additional security can raise the cost. To get the best bargain, it's wise to compare prices.
Can these containers withstand harsh weather conditions?Absolutely. They’re made from durable Corten steel, which stands up to tough weather and resists corrosion. Plus, features like weatherproof seals and reinforced doors keep your stuff safe no matter the conditions.
What sort of maintenance is necessary for side door containers?It's very easy to keep your container in top condition.

This regular maintenance keeps everything safe and extends the life of your container.
