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.
Shipping container buildings are popular due to their cost effectiveness, speed of construction and sustainability.
Turning a steel shipping container, also known as a conex box, sea can or ISO container, into a building can save you money for several reasons.
Once you have your shipping containers purchased, Conex box buildings can be assembled quickly—all you have to do is add a roof!
With ingenuity and imagination, the sky is the limit with container building uses.
These structures are already used for a variety of commercial and residential applications, including:
Shipping containers are typically 20’ or 40’ in length.
A 20’ container is about the size of a standard parking spot. A 20ft container holds about 1,150 cubic feet and could comfortably hold one to two room’s worth of items.
If you plan to store taller items, you might want to opt for a high cube container. A high cube container is one foot taller (9’6”) than the standard height container (8’6”).
The intended dimensions of your building will help you determine the way you group your containers. For example, you can figure out how close or far apart the containers will be based on the width of your building.
If you’re storing taller equipment, you also have the option to stack containers on top of each other for extra height.
SteelMaster’s container roofing kits can be tailored to fit any job site. They are pre-engineered to meet the local wind, snow and seismic design requirements of any location.
The roofs can be mounted on the outer edge of the container or the inner edge of the container.
Your mounting location can depend on several factors, including:
