When a traditional backyard shed simply isn't big enough, step up to the 20' x 13' Heavy-Duty Metal Storage Shed.
With an expansive footprint measuring approximately 19.75' long x 12.66' wide, this extra-large outdoor storage building provides substantial room for vehicles, lawn equipment, tools, workshop equipment, seasonal belongings, and other bulky items that can quickly overwhelm a garage.
Wide front double doors make moving larger equipment in and out easier, while a separate side entry door gives you convenient everyday access without opening the main entrance.
Whether you're trying to reclaim your garage, create dedicated equipment storage, or establish a backyard workshop, this shed gives you room to work with.
The shed provides approximately 250 square feet of exterior footprint, putting it in an entirely different category from a conventional garden shed.
Use the additional space to create dedicated zones for different equipment.
Park appropriate vehicles or recreational equipment inside.
Create shelving and tool-storage areas.
Set aside space for lawn and garden equipment.
Or build a dedicated workshop separate from your primary garage.
The larger footprint gives you flexibility to organize the interior around the way you actually plan to use it.
Large storage buildings need large access points.
The front double-door opening measures approximately:
113.4" W x 77.6" H
At nearly 9.5 feet wide, the front opening provides generous clearance for moving larger equipment into and out of the shed.
That makes the building especially useful for items that would be difficult to maneuver through the narrow doorway found on a traditional garden shed.
Before storing a vehicle or oversized equipment, always compare its exact width and height—including mirrors, attachments, racks, or accessories—with the available door clearance.
You shouldn't have to open oversized double doors every time you need a tool.
A separate side entry door measures approximately:
29.1" W x 72.4" H
Use the side entrance for everyday access to tools, supplies, gardening equipment, or your workshop area while reserving the larger front doors for vehicles and bulky equipment.
It's a simple feature that can make a large storage building considerably easier to use.
The shed is constructed from galvanized steel, providing a substantial metal enclosure for outdoor storage.
Galvanization helps protect steel against corrosion while eliminating many of the maintenance requirements associated with traditional wood storage structures.
The metal construction also gives the shed the appearance and function homeowners often want when storing larger equipment, tools, and machinery.
Large enclosed storage areas benefit from airflow.
This shed incorporates stamped gable vents directly into the structure, providing ventilation without requiring separate vent components to be added afterward.
The integrated vents help promote airflow through the enclosed storage area.
Need somewhere to work on projects without sacrificing your entire garage?
The generous footprint creates the potential for a dedicated workshop environment.
Organize one area with a workbench.
Add appropriate tool cabinets and storage systems.
Keep equipment along another wall.
Use shelving for supplies.
And maintain open floor space for the projects you're currently working on.
The combination of a wide main entrance and separate side door makes the layout particularly useful for workshop and equipment-storage applications.
Garages often become storage buildings long before they stop being parking spaces.
Lawn equipment.
Tools.
Bicycles.
Recreational equipment.
Seasonal decorations.
DIY supplies.
Before long, there's barely enough room left for the vehicle.
Moving appropriate equipment into a dedicated 20' x 13' metal storage building can give you the space to reorganize your property instead of continually trying to squeeze more into the garage.
The large interior can accommodate a wide variety of household and property-storage needs, including:
Lawn tractors and mowers
Garden equipment
Tools and tool cabinets
Workshop equipment
Bicycles
Recreational equipment
Appropriate vehicle storage
Seasonal equipment
Outdoor furniture
Storage totes
