Frequently Asked Questions

Guiding You Through the Completion of Construction

Your local Capital Steel contractor is thoroughly trained by our staff and capable of helping you navigate your project from inception to planning, procurement and finally construction.

What's included in a metal building kit?
Our base building package comes delivered to your site with the primary and secondary framing, roof sheeting, wall panels, fasteners, bracing, sealants, trim and flashing.
How can I customize my building?
We have a menu featuring hundreds of accessories such as walk doors, sectional and roll up doors, gutters and downspouts, windows and even skylights to improve the functionality of your building.
How can I personalize my building?
You can choose to add any combination of colors to the roof, walls and trim. The select will be baked onto the building components prior to delivery. You may also add the look of stucco or stone to your building with optional panels.
How are building prices determined?
The price of your standard building package will be based on the current price of steel, the intended use and the codes and loads required by your locale.
How does my location affect my building price?
If you plan to build in Florida, your building will be designed to withstand higher wind loads than a building delivered to Utah where it may be engineered to endure snow loads. Each condition will require a unique amount of steel.
How does the intended use influence the cost?
A building intended to be used as a garage will most likely require sectional doors, possibly a man door and maybe windows. On the other hand, if you are planning to build an aircraft hangar, a bi-fold door would be necessary. Each component has its own added cost.
What if I need a contractor?
Capital Steel is a one stop shop for all of your building needs! Our builder network is made up of hundreds of contractors who along with the price of your building can estimate how much your concrete, building erection and even turnkey services will cost.
