DROP US A LINE

When your operation goes beyond standard shipping needs, specialised containers provide the flexibility, durability, and design precision necessary to get the job done. Whether you're managing oversized equipment, temperature-sensitive cargo, or looking to build a mobile workspace, we have a range of specialty containers tailored to your industry and use case.

From construction and agriculture to retail and energy, we provide rugged, well-built units that meet strict compliance standards and support long-term deployment. Our special containers are available for sale across California and can be fully modified to fit your unique requirements.

Types of Specialty Shipping Containers

At Midstate, we offer several types of specialty shipping containers, each engineered for specific challenges and operational goals. Below are the most commonly requested builds.

Open-Top Containers

Ideal for cargo that's too tall to load through standard doors, open-top units allow loading from above using cranes or lifts. These feature removable tarpaulin covers or reinforced hard tops, depending on the protection level required. They’re used heavily in construction, mining, and heavy manufacturing industries.

Hard-Top Containers

Similar to open-tops but built with a detachable steel roof, hard-top special-purpose containers provide enhanced security and weather protection. These are ideal for equipment that must be loaded vertically but requires extra shielding. A preferred solution for transporting machinery or parts that can’t be disassembled.

Open-Sided Containers

Open-sided special containers feature one or both long sides that open fully, making them ideal for loading wide materials or creating mobile display spaces. These specialty containers are commonly repurposed into pop-up retail shops, mobile event stations, or field offices in agriculture and construction.

Flat Rack Containers

Flat rack special container units are built without sides or a roof, perfect for oversized or irregularly shaped cargo such as pipes, vehicles, or heavy equipment. These units feature collapsible ends and robust steel frames, offering flexibility and strength. This flatrack option is indispensable for industries where vertical and side access is crucial.

Double-Door Containers

Double-door units feature swinging doors on both ends, allowing easier access to cargo and improved loading/unloading speed. These are excellent for storage operations where throughput and accessibility are key. Explore our durable double-door units to simplify complex supply chains and worksite logistics.

Key Characteristics and Examples of Specialized Containers

Specialised shipping containers are all about solving tough logistical challenges. Designed to meet niche demands, these units typically feature:

  • Reinforced steel framing
  • Custom modifications for ventilation, insulation, and wiring
  • Flexibility in size, ranging from 10’ to 45’
  • Purpose-built solutions for security, mobility, and compliance

For example, one Midstate client in California’s wine country requested a 20-foot specialised unit with insulation, AC, double doors, and built-in shelving to function as a mobile wine lab. Another project involved a specialty storage box used on an oilfield, modified with fire-rated walls, emergency lighting, and spill containment flooring.

Benefits of Specialised Shipping Containers

Specialised containers are more than modified boxes; they’re long-term solutions that save time, reduce buildout costs, and adapt to evolving project goals. 

Some key benefits include:

  • Custom configuration for your business workflow
  • On-site deployment without the need for permanent construction
  • Enhanced storage and operational efficiency
  • Durable materials suitable for extreme weather or remote locations
  • Lower long-term costs compared to fixed infrastructure

Versatile Use Cases

Whether you’re in farming, education, manufacturing, energy, or entertainment, specialty storage containers provide versatility. These units can be used as:

  • Mobile testing labs
  • Construction command centers
  • Equipment shelters
  • Walk-in freezers
  • Drive-through kiosks
  • Outdoor classrooms

Each unit can be built to serve a purpose unique to your business or site needs, with easy transportation and redeployment as operations evolve.

Custom Fit

Every specialty container we produce is made with your custom specs in mind. Need sliding windows, security grilles, solar panels, or high-R-value insulated walls? We’ll tailor the design around your project, ensuring form meets function.

From flooring to roof vents and everything in between, we help you build a special container that supports real work, not just general use.

Safety

Our specialty shipping containers are built to last and made to protect. We integrate safety measures that support compliance with OSHA, CAL/OSHA, and other regulatory standards. Fire-resistant panels, grounded electrical wiring, and reinforced locking systems are all part of our design options.

When security and long-term dependability are critical, our team ensures your shipping module meets the highest standards, so your crew, equipment, and materials stay protected.
