Container Modification FAQs
What is shipping container fabrication or modification?
At Advanced Container Co., shipping container fabrication, modification, and customization includes structural modifications, interior buildouts, and system installations to create offices, workshops, storage units, restrooms, and other purpose-built steel containers.
Do you sell storage containers that are already modified?
No. Advanced Container Co. does not have pre-designed floorplans. Customers sometimes ask if we have ready-made or pre-built units available, but all modifications are built to order. This allows us to customize each container to your exact requirements rather than offering one-size-fits-all solutions.
How long does it take for container modifications?
Customers often ask how long it takes to modify a shipping container. Fabrication timelines at Advanced Container Co. vary based on the scope of work. Simple modifications may take a few weeks, while fully customized builds with electrical, climate control, and interior finishes may take longer.
Are custom fabricated containers portable after modification?
Yes. Even after fabrication, containers built by Advanced Container Co. remain fully portable. They can be relocated to new sites as needed, making them ideal for jobsites, temporary facilities, and changing operations.
Do you require a deposit for custom containers?
Yes. With any modification work, Advanced Container Co. requires a minimum 50% deposit to begin fabrication. Customers often ask how payment works for custom containers—after the initial deposit, the remaining balance is due once the work is complete and prior to delivery. This ensures materials, labor, and scheduling are secured for your project.
I have a large project in the pipeline. Would you be able to handle it?
Yes, we regularly handles large-scale and multi-unit container projects. Customers often ask if we can support bigger or phased builds, and our team is equipped to manage complex fabrication scopes, multiple containers, and longer-term project timelines while maintaining consistent quality.
How do you maintain structural integrity when modifying a shipping container?
A common concern is whether cutting into a shipping container makes it weaker. At Advanced Container Co., structural integrity is maintained by reinforcing all openings, preserving corner castings, and using proper steel framing techniques. This ensures every modified container remains strong, stable, and safe for long-term use.
Can containers be joined, stacked, or combined in custom builds?
Yes. Advanced Container Co. can join and stack shipping containers for custom builds. Containers are engineered for stacking and can be combined side-by-side or vertically to create larger or multi-level structures, with proper reinforcement to maintain strength and load capacity.
A good example of stacking containers can be found on our confined space container page.
Does modifying a container affect its durability or weather resistance?
Many customers want to know if modified containers are still weatherproof. When fabricated by Advanced Container Co., durability and weather resistance are not compromised. Proper sealing, reinforcement, and protective coatings ensure containers remain wind- and watertight—even in harsh environments.
Do I need building permits for a modified container on my property?
Permit requirements depend on local regulations, intended use, and whether the container is temporary or permanent. Please contact us regarding permitting information.
Can container fabrication include climate control systems?
Absolutely, we can install climate control systems such as air conditioning, HVAC, insulation, ventilation, and humidity management as part of a custom container fabrication.
What industries use modified shipping containers?
Advanced Container Co. provides modified shipping containers to almost every industry, including construction, oil and gas, petrochemical, industrial facilities, agriculture, logistics, military, disaster response, and commercial operations.
Why choose Advanced Container for your next container modification project?
