Steel Building Designs

There are two categories of design types, with various subcategories.  Each design has its own benefits and its optimum range of sizes.  With both design types, building length is virtually unlimited.

Quonset Hut (or Arch) Designs

This is the most popular arched building type, due to its extended width, superior strength, durability, & economy Width: from 20'-100'

Least expensive arch design
With its straight walls, the S-Model is best suited for warehouse & equipment storage, as inventory can be stored against all walls with virtually no wasted space Width: from 16'-60'

More expensive than Q-Model, less expensive than P-Model
With its traditional gable-style appearance and & high sidewall clearance, the P-Model is best suited to backyard applications like garages & workshops Width: from 16'-30'

Most expensive arch design (still less expensive than straight walls)
