The Quonset Hut Coating Amount calculator computes the exterior surface area (A) of a Quonset hut based on the height, length, width, corrugation factor, and thickness of coating. This includes the roof and both ends. See YouTube instruction video for this formula HERE.
INSTRUCTIONS: Choose units and enter the following:
Quonset Hut Coating (QHC): The calculator returns the following:
The above can be automatically converted into compatible units via the pull-down menu.
The calculator assumes that the face of the Quonset hut is half of an ellipse (or circle if W = 2*H). From that, the tally of the total surface area gets pretty easy using the formulas for the Area of an Ellipse, and the Circumference of an Ellipse.
The formula for the area of an ellipse is:
A = π•a•b
The circumference of an ellipse has been approximated in several simple formulae including this one by the famous mathematician Rumanujan. The the formula for the circumference of an ellipse used in this calculator is:
`C = pi * [3* (a+b) - sqrt((3*a+b) (a+3*b))]`
where:
Combining the two formulas, the Surface Area of a Quonset Hut is:
SA = A + C/2*L
where:
The surface area of a Quonset Hut is useful for calculating construction material needs and for computing the conductive heat loss of the Quonset hut.
Corrugation refers to the process of shaping a material into a series of parallel ridges and grooves. This is commonly seen in corrugated materials, such as cardboard or metal sheets. The purpose of corrugation is often to add strength and rigidity to the material while maintaining flexibility. In the case of corrugated cardboard, for example, the corrugated structure provides strength and helps the material withstand pressure and impacts. Corrugated metal sheets are used in roofing and packaging for similar reasons.
Corrugation adds complexity to the basic surface area calculation. Without corrugation the surface area of a rectangle can be calculated as length time width. To account for corrugation, and in essence flatten the surface area calculation, one can use a Corrugation Factor (CF) that can by applied to a dimension (e.g., width) in order to make an accurate surface area of a corrugated surface calculation.
Corrugation can have a smooth (curved) or straight segment pattern with squared ends in its profile.
Surface area is a simple length times width calculation, but what if one of the dimensions is not smooth? This is found in corrugated material. To account for this, this calculator has a corrugation factor that is applied to the length and width dimensions to account for corrugation.

To calculate the Corrugation Factor, do the following:
The formula for the Corrugation Factor is:
CF = SL / W
