If you've been searching for storage solutions in Pittsburgh, you've probably encountered two terms: "conex box" and "shipping container." Are they the same thing? Different? Which should you buy or rent for your project? As the owner of Mann's Cans, Pittsburgh's trusted container provider, I get these questions daily.
Here's the simple answer: conex boxes and shipping containers are the same thing. The confusion comes from terminology that evolved over decades in the shipping industry. Whether you call it a conex box, shipping container, cargo container, or ISO container, you're referring to the same standardized steel storage unit.

What is a Conex Box? The Origin of the Term
The term "conex box" comes from CONtainer EXpress, a shipping system developed by the U.S. military in the 1950s. The Army needed a standardized way to transport supplies quickly and efficiently during the Korean War. They created the CONtainer EXpress system, using sturdy steel boxes that could be loaded onto trucks, trains, and ships without repacking contents.
These original military containers were smaller than today's standard shipping containers, measuring 6x6x6 feet or 8x8x8 feet. However, the name "conex" stuck and became widely used across the United States, especially in military and industrial circles.
Today, when people say "conex box," they usually mean any standardized shipping container, regardless of its actual origin or manufacturer. It's simply regional terminology that's particularly common in the Midwest and among construction crews.
Shipping Containers: The Modern Standard
Modern shipping containers evolved from those early military designs but follow International Organization for Standardization (ISO) specifications. These are the containers you see stacked on cargo ships, freight trains, and trucks worldwide.
The most common sizes are:
- 20-foot containers:
20' x 8' x 8'6" (160 square feet).
- 40-foot containers:
40' x 8' x 8'6" (320 square feet).
- 40-foot high cube:
40' x 8' x 9'6" (320 square feet with extra height).
These standardized dimensions ensure containers can fit on any truck, train car, or ship designed for container transport. At Mann's Cans, we stock both 20-foot and 40-foot options in new and used conditions to meet different Pittsburgh-area project needs.
Are There Any Real Differences Between Conex Boxes and Shipping Containers?
In practical terms, no. When you're shopping for containers in Pittsburgh, vendors use both terms interchangeably. However, there are a few subtle distinctions worth understanding.
Term | What it usually means | Common Pittsburgh use |
Conex box | Regional or job-site term for a steel shipping container | Construction storage and job-site equipment. |
Shipping container | ISO-standardized steel container used in freight and storage | Buying, renting, delivery, and modifications. |
Cargo container | Another general term for a freight or storage container | Commercial storage and custom conversions. |
Age and Origin
If you encounter an actual vintage military conex from the 1950s-1980s, it might have different dimensions than modern ISO containers. These are rare and typically found only in military surplus yards. Most "conex boxes" sold today are standard ISO shipping containers.
Regional Terminology Preferences
Different industries and regions favor different terms:
- Construction sites:
Often call them "conex boxes".
- Shipping industry:
Uses "containers" or "shipping containers".

Either term is fine.

Popular Uses for Conex Boxes/Shipping Containers in Pittsburgh
Pittsburgh's diverse economy creates demand for containers across many industries. The region's mix of construction, technology, healthcare, education, and manufacturing drives unique container applications not seen in other markets.
The ongoing urban development in neighborhoods like East Liberty, Lawrenceville, and the Strip District creates consistent demand for construction storage. Meanwhile, the growing tech sector in Oakland and suburban corporate campuses drives demand for innovative workspace solutions.
Here's how our customers use them:
Construction Storage
Contractors use containers as secure, weather-resistant storage for tools, materials, and equipment on job sites. The steel construction provides superior security compared to wood sheds or temporary structures.
Residential Storage
Homeowners facing renovation projects, downsizing, or seasonal storage needs find containers perfect for temporary or long-term storage. They're particularly popular in areas like Upper St. Clair and Mt. Lebanon where garage space is limited.
Commercial Inventory
Small businesses use containers for overflow inventory, especially during peak seasons. Retailers, landscapers, and equipment rental companies rely on containers for cost-effective storage expansion.
Agricultural Applications
Farms throughout Washington and Westmoreland counties use containers for equipment storage, feed protection, and workshop space. The weatherproof design protects valuable machinery and supplies.
Container Modifications
Pittsburgh's growing interest in alternative housing and workspaces drives demand for container modifications:
Tiny homes and ADUs.
Home offices and studios.
Pop-up retail spaces.
Workshop and maker spaces.

Rent vs Buy: Which Makes Sense for Your Pittsburgh Project?
The decision between renting and buying depends on your timeline and intended use:
Consider Renting When:
You need storage for less than 18 months.
It's a temporary construction project.
You want to test container storage before committing.
Cash flow is a concern.
Consider Buying When:
You need long-term storage (2+ years).
You plan modifications.
You want to build equity in the asset.
You're creating a permanent workshop or studio.
Rent-to-Own Option
Mann's Cans offers flexible rent-to-own programs that let you start with monthly payments and build toward ownership. Terms range from 12 to 48 months, with no credit checks required for most programs.
This option works particularly well for customers who want to test container storage before committing to purchase. Many Pittsburgh-area contractors start with rental for seasonal projects, then convert to ownership when they realize the long-term value. The rent-to-own structure also helps with cash flow management during busy construction seasons.
Early payoff discounts are available, typically offering 33% off the remaining balance. This makes rent-to-own competitive with traditional financing while providing more flexibility.
What to Consider When Shopping for Conex Boxes in Pittsburgh
Delivery Access
Container delivery requires a tilt-bed truck, which needs adequate clearance and firm ground. Consider:
Overhead clearance (minimum 14 feet).
Street access for a truck and trailer.
Level placement area.
Distance from property line (may require permits).
Local Regulations and Zoning
Pittsburgh-area municipalities have varying rules about containers on residential property. Each borough, township, and the city itself maintains different zoning codes, making local research essential before delivery.
Common requirements across Western Pennsylvania include:
- Setback distances:
Usually 5-10 feet from property lines.
- Height restrictions:
Most areas limit containers to 8.5 feet in residential zones.
- Screening requirements:
Some municipalities require visual barriers or landscaping.
- Time limits:
Temporary placement often limited to 30-90 days without permits.
- Foundation requirements:
Some areas require concrete pads or permanent foundations.
For example, the City of Pittsburgh allows temporary containers for construction projects but requires permits for permanent placement. Suburban townships like Upper St. Clair have stricter aesthetic requirements, while more industrial areas like West Mifflin are generally more permissive.
Always check with your local zoning office before delivery. Mann's Cans can help navigate these requirements and recommend placement strategies that comply with local codes.
Security Features
Standard containers include:
Lockbox for padlock security.
Heavy-duty cam locks on doors.
14-gauge corrugated steel walls.
Weather seals around doors.
Additional security options like alarm systems or upgraded locks are available for high-value storage needs.

Frequently Asked Questions About Conex Boxes and Shipping Containers
Are conex boxes waterproof?
Yes, containers in "Wind and Water Tight" condition or better are designed to be weatherproof. They feature rubber door seals and are built to protect cargo during ocean voyages. However, older containers or those in "as-is" condition may have minor leaks.
Can you bury a conex box?
Standard shipping containers are not designed for underground placement. The walls can collapse under soil pressure. If you need underground storage, special reinforcement and professional engineering are required.
How much does a conex box weigh?
Empty container weights:
- 20-foot:
4,850-5,500 pounds.
- 40-foot standard:
8,160-8,800 pounds.
- 40-foot high cube:
8,750-9,300 pounds.
Can containers be modified for electrical and plumbing?
Yes, containers can be modified for electrical outlets, lighting, plumbing, and HVAC. However, modifications should be performed by licensed contractors familiar with local building codes.
Do I need a permit for a container on my property?
Permit requirements vary by municipality. Temporary placement (under 30 days) typically doesn't require permits, but longer-term placement often does. Check with your local zoning office before delivery.
How long do shipping containers last?
With proper maintenance, shipping containers can last 25-30 years or longer. The marine-grade steel construction is designed to withstand harsh ocean conditions, making them extremely durable for land-based storage.
