What Are Specialty Shipping Containers?
Specialty shipping containers are modified or purpose-built containers designed for specific cargo requirements that standard containers cannot handle. Unlike standard dry containers used for general storage and shipping, specialty containers feature unique designs, equipment, or modifications to transport temperature-sensitive goods, oversized cargo, or materials requiring special loading methods.
The three main types of specialty containers are:
Reefer (refrigerated) containers - Temperature-controlled units maintaining -40°F to +65°F
Flat rack containers - Open-sided units for oversized or heavy cargo up to 45,000 kg
Open-top containers - Crane-loading units with removable roofs for tall cargo
Why Specialty Containers Matter for Your Business
when you're dealing with temperature-sensitive goods, oversized cargo, or crane-loading requirements, you need specialized solutions. Being the main reason these containers matter.
Reefer containers maintain precise temperatures for perishables, pharmaceuticals, and sensitive materials
Flat rack containers handle oversized loads that won't fit through standard container doors
Open-top containers accommodate tall cargo that requires crane loading from above
The key is understanding which specialty shipping container matches your specific application - and that's exactly what this guide will help you determine.

What Are Reefer Containers? Complete Temperature-Controlled Guide
Reefer containers (short for "refrigerated") are sophisticated mobile cold storage units that maintain precise temperatures during transport and storage. These aren't simple coolers - they're engineered systems capable of maintaining temperatures from -40°F to +65°F with remarkable precision.
How Do Reefer Containers Work?
Modern reefer containers use advanced refrigeration units powered by 440/460V, 3-phase electrical systems. The units circulate conditioned air throughout the container using specialized T-bar flooring that ensures even temperature distribution. Our reefer containers feature:
Stainless steel or aluminum food-grade interiors
Remote monitoring capabilities for real-time temperature tracking
Precise humidity control to prevent condensation and spoilage
Emergency power backup systems for critical applications
Industries Using Reefer Containers
Pharmaceutical Cold Chain Solutions Our reefer containers meet FDA requirements for pharmaceutical storage with:
Validated temperature mapping
24/7 monitoring systems
Backup power integration
cGMP compliance documentation
Temperature-sensitive medications, vaccines, and medical supplies require strict temperature control. Our pharmaceutical customers rely on reefers to maintain the cold chain during storage and distribution.
"The 40ft reefer we purchased has been perfect for our vaccine distribution program. The temperature control is precise, and the remote monitoring gives us peace of mind during transport." - Jason R., Small Business Owner
Food Service & Restaurant Applications From farm-to-table restaurants to catering companies, reefer containers provide reliable cold storage that scales with business needs. Popular applications include:
Fresh produce storage for restaurants
Catering event cold storage
Farmers market vendors
Food truck operations
Wine & Beverage Industry Wineries and beverage distributors use reefer containers to protect products from temperature fluctuations that can affect quality and taste.
Event Management Large events, festivals, and outdoor gatherings use reefer containers for temporary cold storage when traditional refrigeration isn't available.

How Do Flat Rack Containers Work for Oversized Cargo?
Flat rack containers are the workhorses of oversized cargo transport. With collapsible or fixed end walls and no side walls or roof, these containers accommodate loads that simply won't fit through standard container doors.
When Should You Use Flat Rack Containers?
Construction & Heavy Machinery Transport Moving excavators, bulldozers, cranes, and other heavy equipment requires the open-side access that flat racks provide. Standard containers can't accommodate:
Equipment wider than 7'6"
Machinery taller than 7'10"
Irregularly shaped construction materials
Items requiring crane loading from the side
Automotive Transport Solutions Car dealerships, auto auctions, and vehicle transporters use flat racks for:
Multiple vehicle shipments
Oversized vehicles (RVs, boats, construction vehicles)
Classic car transport requiring extra protection
Industrial Materials Handling Manufacturing facilities and industrial suppliers transport:
Steel beams and structural materials
Large pipes and ducting
Manufacturing equipment
Bulk raw materials
"Eric from Shipping Containers On Sale was incredibly helpful. He walked me through the differences between grades, sizes, and how to spot misleading ads elsewhere. The container was delivered and placed within 3 days. Outstanding service!" - Erica L., Construction Manager
Flat Rack Container Types Explained
Collapsible End Flat Racks These units feature removable end walls that fold down for efficient empty storage and stacking. When not in use, multiple empty flat racks can be stacked to save space.
Fixed End Flat Racks More robust construction with permanent end walls provides maximum strength for the heaviest loads. These are preferred for regular heavy-duty applications.
Flat Rack Container Specifications
20ft Flat Rack Container:
Platform Dimensions: 20' L x 8' W
Empty Weight: Approximately 6,041 lbs
Payload Capacity: Up to 45,000 lbs (varies by manufacturer)
End Wall Height: Typically 8'6" (when erected)
Lashing Points: Multiple tie-down points for secure cargo
40ft Flat Rack Container - Collapsible Ends:
Platform Dimensions: 40' L x 8' W
Empty Weight: Approximately 11,025 lbs
Payload Capacity: Up to 99,208 lbs (45,000 kg)
Construction: ISO-certified steel with reinforced corner castings
Features: Marine-grade timber flooring, multiple lashing configurations
Flat Rack Container Pricing
Flat rack containers command premium prices due to their specialized design and heavy-duty construction:
20ft Flat Rack: $4,000 - $6,000 (typical range)
40ft Flat Rack: $6,000 - $9,000 (typical range)
Collapsible vs. Fixed: Collapsible units typically cost 10-15% more due to complex hinge mechanisms
Delivery Considerations: Flat rack containers require specialized transport equipment and may have different delivery requirements than standard containers. Our delivery team coordinates appropriate equipment for safe placement.
When Should You Choose Open-Top Containers? {#open-top-containers}

How to Choose the Right Specialty Container for Your Needs {#choosing-guide}
Selecting the correct specialty container depends on understanding your specific requirements. Here's our systematic approach to help you make the right choice:
Step 1: Analyze Your Cargo Requirements
Temperature Sensitivity Assessment
Reefer containers for anything requiring temperature control
Consider temperature range: frozen foods (-10°F to 0°F), fresh produce (32°F to 40°F), pharmaceuticals (specific ranges)
Factor in humidity control needs
Size and Shape Analysis
Standard containers for cargo fitting within 7'8" wide x 7'10" high x 39'5" long
Flat racks for oversized width, length, or irregularly shaped items
Open-tops for cargo exceeding height limits or requiring top-loading
Loading Method Requirements
Standard containers for forklift or manual loading through doors
Flat racks for crane loading from sides or equipment driving on/off
Open-tops for overhead crane loading or tall item insertion
Step 2: Consider Your Operational Environment
Power Availability for Reefers Reefer containers require 440/460V, 3-phase electrical connections. If you don't have appropriate power:
Budget for electrical upgrades ($500-$2,000)
Consider generator backup for critical applications
Plan for ongoing electricity costs ($50-100/month)
Loading Equipment Access
Crane access for open-top containers
Forklift capability for side-loading flat racks
Ground conditions suitable for heavy equipment operation
Duration of Use Planning
Short-term rentals may be more cost-effective for temporary needs
Purchase makes sense for ongoing applications
Rent-to-own programs bridge the gap with flexible monthly options
Step 3: Evaluate Total Cost of Ownership
Initial Investment Analysis
Specialty containers cost more than standard units
Factor in delivery and setup costs
Consider modification expenses
Ongoing Operational Expenses
Reefer containers: Electricity, maintenance, monitoring
Flat racks: Special transport requirements, storage space
Open-tops: Tarpaulin replacement, crane rental for loading
Resale Value Consideration Specialty containers typically retain value better than standard units due to limited supply and specific demand in industries requiring these solutions.
