Components of a Fabric Building

Components of a Fabric Building

Published on March 13th at 8:11 AM by Cobra Structures

Let us start with engineering. Ideally, rather than just having a building designed, it should be engineered with your environmental (wind, snow loads, exposure, soil type, etc) conditions factored in. But the best planning is worthless if the engineering and materials that go into the actual structure are inferior.

The Canadian Beef Industry

The Canadian Beef Industry

Published on February 22nd at 12:42 PM by Cobra Structures

The Canadian beef industry is in a state of flux, and has been since the BSE crisis. Exports to the USA are down significantly, and markets in the Far East are only slowly growing. Domestic demand is also down, while the Hong Kong market is emerging as a strong one and is our Number 2 importer of beef, ahead of Mexico. Herd sizes are down and the number of grazing acres has declined, partly due to adverse weather conditions. Throughout these conditions, beef prices are up, making the return on investment better.

HDPE vs. PVC

HDPE vs. PVC

Published on February 10th at 9:22 AM by Cobra Structures

The differences between PVC and HDPE lie both in the applications for each and their composition. While PVC is the more common of the two, high density polyethylene is used in specific circumstances that make polyvinyl chloride unattractive or unsuitable. PVC is a relatively inexpensive and fairly durable vinyl polymer. High density polyethylene is a thermoplastic made from petroleum. Both PVC and HDPE are considered plastics.

Galvalume only partly consists of steel. In fact, Galvalume consists of steel coil coated with an alloy of 55% aluminum and 45% zinc. It has a smoother appearance than galvanized steel. A variation on Galvalume is Galvalume Plus, which is Galvalume with a thin acrylic coating.

Happy Cows are Productive Cows

Happy Cows are Productive Cows

Published on January 9th at 3:04 PM by Cobra Structures

Happy cows are productive cows. It is a hybridization of an old saying, yet North American farmers paid little attention to the contentment of their animals until the late 1960s. Then research came along that showed that a comfortable environment actually did make for happy animals and happy cows produced more milk.

First Nations Housing in Fabric Buildings

First Nations Housing in Fabric Buildings

Published on December 15th at 8:25 AM by Cobra Structures

On a recent visit to a northern Manitoba First Nations community, I sat down with a few of the residents to discuss their housing issues. It was early spring and the frost was just coming out of the ground. Like many northern communities, homes are built on a combination of rock and moss, none of which is level. In the spring, the moisture in the moss expands, pushing a corner of the foundation of the home upward. Read full article…

Metal vs. Fabric Buildings

Metal vs. Fabric Buildings

Published on December 5th at 10:56 AM by Cobra Structures

Leakage is one of the problems common to older metal buildings. Cycles of heat and cold, sun and wind and differences between the internal and external conditions lead to warping of the metal so that rivets pop or moisture accumulations lead to rust penetration at key points. Read full article…

From air-reinforced inflated recreation centres to monstrous stretched canopies covering stadiums - tells us that this is new, innovative technology that only is possible because of recent inventions in specialty fabrics. "Space-age", we think. Wrong. Tension-fabric buildings actually pre-date the iron age. Read full article…

Published on November 14th at 9:02 AM by Cobra Structures

The magic of outdoor rinks in Canada is that, of course, that they are outdoors. However, small communities and remote villages often do not have enclosed arenas because of cost or difficulty constructing and maintaining these structures. Read full article…

Advantages of Fabric Buildings

Advantages of Fabric Buildings

Published on September 28th at 10:15 AM by Cobra Structures

In Canada, weather presents a huge challenge. In summer, extreme heat and abundant sunlight curl asphalt shingles, dry and crack timber, warp steel. The metals transmit both the heat and the cold, making for significant problems in controlling internal temperature and humidity. Wood rots in high moisture environment and is often scarce in remote areas, including the north and arid areas of southwest USA. Read full article…

The Basics of Tension Fabric Buildings

The Basics of Tension Fabric Buildings

Published on September 21st at 9:15 AM by Cobra Structures

While pressure washing a vehicle inside a Quonset, I noticed that moisture was dripping from the curved roof, yet none of the spray was reaching higher than a few feet above the truck. It was cool outside, and I was using warm water. The vapour was rising, condensing on the upper reaches of the steel ribbing and falling like rain. Read full article…
