5 Container Building Questions to Ask Before Starting Your Project

Why are container buildings so popular?

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!

What are container buildings used for?

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:

  • Job Site Storage/Tool Room
  • Vehicle and Equipment Storage
  • Office Buildings
  • Workshop
  • Garages

What dimension shipping container will I need?

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”).

How will I group my containers?

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.

What are some roofing options for container buildings?

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:

  • Water run-off placements
  • The height/radius of the roof
  • If storage under the roof is a priority
