container cover steel building on commercial shipping containers

A New Kind of Industrial Storage Solution: Shipping Container Roof System Kits

Convert your existing shipping containers into functional and secure storage or working area by adding a SteelMaster shipping container cover.

Our unique container roof system was designed with durability and usefulness in mind.

SteelMaster provides an economical solution for a variety of needs by simply covering the space between shipping containers, also known as Conex boxes or ISO containers, with our innovative steel roofing system kits.

What options do I have for my container cover building?

Container cover buildings are defined by two design factors: placement of containers and total building footprint. Depending on your application and future plans for the space, either option grants you certain advantages. 

No matter the job site, our shipping container roof structures can be tailored to fit virtually any specifications. 

They can be open-ended or enclosed and the size can be customized to the width between the two containers and height requirements of the project.

What are container cover roofs used for?

The advantage of using a roof between two unused containers is that it transforms wasted space into something useful. 

What you do with that now unwasted space can be up to you. SteelMaster Buildings container roof system kits offer a clear span design, providing 100% usable space which is perfect for industrial, commercial, or construction environments. 

Some of our most popular applications include but certainly aren’t limited to:

  • Storage buildings
  • Onsite heavy equipment cover
  • Workshops
  • Offices

How can I customize my project?

SteelMaster’s team of engineers and designers can create custom plans and quotes so that your building is exactly how you dreamt it. 

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. 

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 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. 

Regardless of your needs, SteelMaster can offer you a budget-friendly solution that is easy to erect. You can contact us now for a custom quote!

Which edge should the roof be placed upon?

Roofs can be attached to either the inside edges or outside edges of the two containers, referred to as “inside mounts” and “outside mounts.” 

Roofs on the inside edge decrease the size of the metal roof used, but doesn’t cover the shipping containers themselves. 

Roofs on the outside edge are larger and enclose the entirety of the footprint of the building. Outside mounts clear water from the roof and allow for extra dry storage on top of boxes

The advantage of inside mounts make the roof narrower, stronger and uses less material. Therefore, it is typically cheaper depending on your exact configuration.

What size of container cover building is right for me?

Typically the smallest roof someone asks for is about 20 feet, though we have designed smaller buildings like container sheds or shipping container garages

Dimensions may vary depending on your location, but you’ll get the most bang for your buck by having a width of 60 feet or less. However, our project managers can engineer to larger widths if necessary. 

However, there is no limit to the amount of containers that can be stacked on top of one another, so the need for a larger building can be addressed while keeping the price of the building reasonable. 

Stacking containers to make the sides of the building provide more straight-walled height to the building and provides extra compartment storage. 

How difficult is it to install container roofs?

SteelMaster pioneered shipping container roof systems in and designed the process of installing them to be as simple to erect as they are to use. Our shipping container roof kits are made of pre-cut steel panels that only use only one type of nut and bolt. 

This means the panels can be quickly and easily assembled to create protected working areas or storage spaces. Even after a job is done, they are designed to move to the next job site easily, as our commercial metal roof systems can be permanent or portable.

What is the foundation for my container building? Does my site need to be leveled?

Shipping containers themselves can act as the structural base to your building, saving you time and money. 

It is important to make sure the ground is level before you place your containers at your build site. This is because leveling your building will provide a uniform base for your shipping container building. 

If the ground is not level, your building could lean to one side and your roof panels, sides and ends may not line up properly.

Prepare your site before leveling by removing items that could affect the base quality, like:

  • Debris
  • Rocks
  • Tree and tree roots

Additionally, make sure there is enough room to allow workers and equipment to move around your site.

Why use steel? Why use SteelMaster steel?

Unlike fabric covers that tear easily or traditional roofing that requires maintenance and replacement, SteelMaster’s roof kits are manufactured to last for years after they’re purchased. 

Further, they are pre-engineered to meet local wind, snow, and seismic design requirements of your location – no matter your location! 

SteelMaster uses industrial-strength, commercial-grade steel panels in a minimum of 22 gauge thickness. Our panels are backed by a 30 year warranty, and coated with a top of the line anti-corrosion agent, Galvalume Plus. 

You can be confident that the building will have minimal maintenance costs and stand the test of time. 

Where did the idea for container covers come from?

Before it went out of business, California-based company Cube Depot experimented with the idea of using intermodal containers as the structural base of storage buildings. 

However, they were unsure of how to create a roofing system for the building. 

A team of SteelMaster design specialists developed a unique container roofing system, sacrificing neither design nor cost efficiency. 

The project also held up to design expectations and created a very rugged structure that was pleasing to the eye.

When you need an economical, secure industrial storage solution, SteelMaster roofs for shipping containers are the best option on the market.
