What is the difference between an arch designed Accu-Steel Cover Building and a flat roof and gable peak building?

Accu-Steel Cover Buildings are engineered with time tested compressive arch design technology. This arch design is the most efficient design to transfer building loads to the foundation and maintain equal cover tension while requiring the least amount of material. The main downfall of the flat roof and gable peak cover building design appears when a fabric is stretched over a flat plane without a curve or other support for the fabric; the fabric will wrinkle or move in the wind.

This type of movement can lead to premature cover failure. Try this experiment: Take a piece of paper outside in the wind and try to stretch it flat between your hands, then try to stretch it over your leg. You will notice when the paper is pulled around your leg (or stretched in a supportive arch) it has equal tension and the paper does not wrinkle or move in the wind.

Keeping proper tension on a flat surface is very challenging regardless of what a salesperson tells you. The other advantage to an arch ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
