Is it a leak….or condensation?

Condensation in steel buildings is often mistaken for leakage from roofing failure. Although condensation can lead to premature deterioration of your steel buildings, it can be safely and easily solved by increasing circulation and ventilation. Windows, doors and roof vents are necessary to controlling condensation and should be considered when ready to purchase your new steel building. Fans and dehumidifiers as well as proper insulation and moisture barriers may also be considered.

Heat Transfer

Effectively controlling temperature in a steel building requires insulation to be present along exterior walls and roof. When a temperature differential is present in an enclosed steel building, heat will work from warmer areas to colder areas until the temperature in the building has stabilized. At the point of thermal stabilization, the cooler (and heavier) air will be present at lower elevations and warmer air will be present at the roofline. The function of insulation is to help stabilize air temperature at more desirable levels. When it is hot outside, preventing heat from transferring into the building is the goal, and of course in the winter we want heat to remain inside.
Heat transfer in steel structures occurs in two ways:
Convection : Occurs with the physical movement of air. There are two types of convectional heat movement. The first is natural, where hot air rises displacing the cold air and moving it down. The second type is forced or mechanical convection. This occurs when an object, like a fan, physically moves or “forces” the air to move. Convection can be solved by supplying efficient ventilation such as roof vents, windows and doors.
Radiation : Occurs when an object is warmer or hotter than the air around it. For example, the sun, which is hotter than everything around it, radiates heat waves that travel through the air and is either absorbed by or reflected by the surface it comes in contact with. Radiation is normally controlled with some form of insulation material.

Why are steel buildings so popular?

The main reason is price. The cost of steel buildings are less per square foot than any other known form of construction, and can be erected quickly, offering its owners faster access to their new building. Since steel is 100% recyclable, steel buildings have become one of the greenest construction methods available on the market today. Steel buildings construction have also been able to reduce its environmental impact in a variety of ways: (1) Raw Materials; (2) Design; (3) Construction; (4) Maintenance; and, (5) Disposal. Other important factors are its strength, mobility, flexibility, functionality and portability.

Allied Steel

Flo-Coat® Galvanized Steel Tubing


Flo-Coat ® galvanized steel tubing is the original in-line galvanized product. It is manufactured using the advanced processing technique of in-line galvanizing first introduced  by Allied in 1959.

Over the years the product has benefitted from continuous advances in technologies and processes. Flo-coat tubing provides advanced levels of corrosion protection, while having the ability to be painted or powder coated for aesthetic purposes with little advance preparation. In addition to its longevity, Allied’s cold forming process delivers higher strength levels than other competitive products. The product typically carries a minimum 50ksi yield and 55ksi tensile strength.
