My current building design is based on using a prefab metal building as the structure. It has become clear to me that for a variety of reasons the interior finish walls will be on an independent stud wall system. See below image from the Rhodes Building Systems blog.




Metal Siding and Roof Details


This article on Metal Roofing and Costs has this cost information:


Cost Information – Part 1

Metal siding has a price range of $5.00 to $35.00 per sq. ft. installed.

Note: the above cost range covers 4 different material options:

  • Steel is usually under $10.00 per sq. ft. installed, unless going with architectural grade material or design options.

  • Aluminum is usually under $12.00 per sq. ft. installed, unless going with architectural grade material or design options.

  • Zinc comes in at around $10.00 to $20.00 per sq. ft.

  • Copper is the most expensive option that goes up to $20.00 to $35.00 per sq. ft. installed.

I am curious about ZAM (Zinc-Aluminum-Magnesium Alloy) coatings for metal. The company website is here. What does it look like unpainted?


Companies providing Metal Buildings

Morton Buildings (Cobleskill, New York)

I like this company!


Armstrong Steel Building Systems has a lot of brochures:

Du-Ben Steel Buildings seems to be a local company in upstate NY that does varied and large projects.
