STEEL BUILDING FEATURES, DESIGN & MANUFACTURING PROCESS

Curvco Steel Structures are manufactured in the U.S. using 100% Galvalume, the highest grade commercial steel made in the US.

Galvalume is a coating on the steel substrate that is applied at the steel mill. This coating is a mixture of some of the toughest metals including Aluminum (55%), Zinc (43%), and Silicon (2%). The advantage of Galvalume is the aluminum's ability to create a highly corrosion-resistant oxide film combined with the sacrificial action of zinc. The end result is a coating which provides excellent corrosion resistance on the sheet (steel panel) while still providing cutting-edge corrosion protection.

This unique coating forms an almost impervious (impenetrable) shield over the steel; in laboratory testing it has 7 times the resistance to rust as galvanized. It is extremely effective, especially in regions subjected to corrosive environments or acid rain. For this reason Curvco offers a 35-year non-prorated warranty against rust perforation.

Why Steel?

Steel is a vital part of our everyday lives from the cars we drive, the trains we ride, the appliances that make our lives easier and much more. Steel is durable and the most recycled material on earth. The steel industry has invested in the latest technologies to make steel more innovative, lower in cost to you and stronger than ever. Here are just some of the benefits of building with steel:

• Strong and Lightweight – Significantly stronger than wood, needs little or maintenance and easy to work with and more economical.
• Durable – Won’t crack, chip or warp. Can be engineered to better withstand hurricanes and earthquakes.
• Non-combustible – Fire resistant material.
• Versatility – Can be custom formed and cut to create high endwalls and large open spaces while maintaining its durability.
• Better for the Environment – Saves trees, is not treated with pesticides or other chemicals and does not encourage mold to form.

Curvco steel hardware consists of a one-size nut-and-bolt for the entire building! The bolt features a super resilient JS-500 clearcoat coating. In a military Kesternich saltwater cabinet test, this bolt withstood over 700 hours without showing any surface rust! (A standard hardware bolt only lasts 70-90 hours.) The United States Army Corps of Engineers has certified this bolt as superior in applications for the US Armed Forces. Just another way Curvco can save you time and money while providing the highest quality product!

All the steel building arch and end-wall panels are pre-formed, pre-drilled, and pre-cut. No field welding is necessary. Since the lip and the last 9 inches at the end of each arch panel are flat, the arch sections bolt together super-tight, as the bolts only rest on flat-to-flat steel. The end panels are all pre-cut and numbered for easy installation and assembly.

Every Curvco steel building has been pre-engineered and designed to meet your local wind, snow, and seismic conditions. Since Curvco's buildings are based on an arch configuration with a deep corrugation using heavy-gauge steel, pound for pound they are the most efficiently designed steel buildings. This enables them to withstand hurricane-force winds, the heaviest snow-loads, and even tremendous seismic activity. They have been laboratory tested against hurricane force winds and approved for use by the state of Florida (FL5897), FL5898).

When the arch panels are bolted together and overlap from panel to panel, and, at each lip every 2’ down the length it doubles the steel thickness. This overlapping or "doubling" of the thickness simulates having a steel beam every 2’ down the length and a steel plate wherever the panels bolt together. This design combined with the deep corrugation and heavy gauge of the steel makes the Curvco Steel Building pound for pound the strongest pre-engineered steel building in the world.

Curvco Steel Structures' standard models can usually accommodate virtually any application. In cases where a customer has a unique application our engineers will modify existing models or custom design a building solution. Using CAD (computer aided design) software they can easily tailor the product to accommodate often difficult criteria all at a significantly lower cost than conventional construction. It is because of this ability and attention to customers’ needs that Curvco has cultivated years of repeat business from many fortune 500 companies and Government agencies. Some of the custom or special uses Curvco designs for the buildings are:

• crane liftable buildings
• covering conveyor systems
• mounting to a barge or ship deck
• mobile cover- -attaching to rails that can be rolled on a track into place
