Why Choose Us for your next metal building selection?

The majority of I-beam steel buildings sold in the USA initiate from 3 large corporations. These corporations primarily distribute (sell) their prefabricated metal buildings through subsidiaries, brokers and contractors. Therefore even if you get a 100 bids, you are still reviewing primarily the same building materials sold by different re-sellers. 

Why continue the archaic method of collecting random quotes from traditional outlets that sell at retail prices?

Solid I-beams

Some firms have elected to use a back-to-back Cezz members- which are a cheaper form of construction- instead of I-beam for metal buildings widths of 40’ and less.  This weaker design increases concrete cost as well as causes screws to loosen in time. So any money saved on their building is totally lost when concrete cost is factor in.

Long Life Fasteners

A building’s integrity is secured by the quality of its fastener.  Long-life screws provide a lifetime warranty against red rust on the head of the fastener. Generally made of Zinc, the head provides superior corrosion resistance, along with compatibility of the metal sheets. They are generally used along the coastal regions to guard against the corrosive environment. They are also recommended for roof systems with exposed fasteners throughout the county.
