Why aluminum frames?

Aluminum is a durable, lightweight and very corrosion resistant metal, which makes it the best choice for portable shelters. This is particularly true when compared to steel; steel is heavy and highly corrosive. Though steel may be coated with a corrosive protectant such as zinc, in the manufacture of steel frame parts, the zinc is ground off prior to welding, leaving the part more likely to corrode at a critical joint. Specifying aluminum frames assures a long lasting, storable, non-corrosive shelter.

What is radio frequency welding and why is it important?

Radio frequency welding is used to join fabric together to form shelter panels. Fabric is overlapped and pressed together with a bar simultaneously with the application of radio frequency waves, which heat between the two overlapped fabrics. The heating from the radio frequency wave combines with the intense pressure of the bar to mix the molecules of the fabric together. Radio frequency welding is considered state of the art and assures a long lasting shelter cover. In contrast, other methods, such as hot air welding, apply heat to only the outside of the overlapped fabric and apply significantly less pressure. As a result, these types of fabric welds are significantly less durable. Specify radio frequency welding for durability and long life.

Why are the corridors 78” wide and why do they have straight walls?

The width of 78 inches, combined with straight walls, allows corridor sections to attach to shelters with double doors. The straight walls also allow for availability of more options, such as side exits and windows.
