Container Cover Configurations

Most of the container covers we sell are custom designed to meet unique usage, environmental regulation, and code requirements. These are the main ways they differ.

Open-Ended Container Roof Structure

Open-Ended Container Roof Structure

  • Two shipping containers with no endwalls
  • Most common container cover configuration
  • Typically found on construction sites or other working areas
Partially-Enclosed Container Roof Structure

Partially-Enclosed Container Roof Structure

  • Common for bulk storage
  • Allows large equipment to drive inside and easily maneuver throughout the structure
  • Another container can be moved against the back of the structure to create a partial endwall
Fully Enclosed Container Roof Structure

Fully Enclosed Container Roof Structure

  • Prefabricated steel endwalls on both ends can be used for a more conventional building appearance
  • Offers added security/protection for items inside of structure
  • Can add garage door or other openings needed to endwalls

Mounting Your Container Cover Roof

Roofs can be attached to either the inside edges or outside edges of the two containers, referred to as “inside mounts” and “outside mounts.” For the largest industrial-scale projects builders can also mount a roof on top of stacks of two shipping containers.

Outside Mount Roof

Outside Mount Roof

  • Ideal for adding endwalls & enclosing space
  • Roof completely covers the containers
  • Clears water from the roof
  • Allows for extra dry storage on top of conex boxes
Inside Mount Roof

Inside Mount Roof

  • Typically cheaper depending on configuration
  • Covers only space between shipping containers
  • Ideal for creating a covered workspace between units
  • Makes the roof narrower & more cost-effective

Custom Container Cover Options

From easy to advanced, we provide options in configuring a container cover building that fits an industry need.

Customization Options Open Ended Structure Fully Enclosed Container Building
Endwalls None needed. If it’s acting as equipment storage, keeping the ends open is an option Can be customized to include any type of entryway that fits underneath the roof and can be aesthetically upgraded
Accessories None needed. With no endwalls, you won’t require optional add-ons to complete the building Steel endwalls, doors, and skylights are common options for enclosed structures
Doors None needed Can meet any door requirements, including man and/or garage doors
I priced it out with three different companies and [SteelMaster was] the quickest response and the best price for what we were looking for.

Shipping Container Building FAQs

What’s a container cover building?

A container cover building installs a roof between two existing shipping containers and converts wasted space into a functional building.

Are container cover roofs expensive?

The short answer is no. More specifically, with the money saved on construction, maintenance costs, and using our team of experts to design your building, a container roof becomes one of the most economical building choices on the market.

Our projects and prices range from just supplying the prefabricated corrugated steel panels and connector plates to designing and delivering commercial-scale warehousing solutions.

How difficult is it to install container roofs?

Shipping container roof systems are designed to be as simple to erect as they are to use. Kits are made of pre-cut steel panels that only use one type of nut and bolt.

What are the available sizes for shipping container buildings?

The smallest container cover building width we’d suggest is 20′ with the largest spanning 50′ wide.  Keep in mind container cover building dimensions can be anywhere in between these sizes and in certain geographies, larger models may be available.

What are container cover roofs used for?

Popular for industrial, commercial or construction applications, container covers are one of the most versatile and affordable building options available. Applications include but certainly aren’t limited to:

  • Storage buildings
  • Garages
  • Onsite heavy equipment cover
  • Workshops
  • Barns
  • Offices
  • Sheds

How can I customize my project?

We work directly with our clients to design and engineer custom container buildings. From the space between the containers to the parts and accessories you want, each container cover we sell is designed only for our customers. Our team allows you to keep it simple with a dirt floor or go large with a secure storage facility.
