When it comes to draining of a canopy, the myth (yes myth) is that it has to be sloped in order to drain. Understandably the theory of sloping the canopy is legitimate however keep in mind that a flat surface does not collect water. Flat single deck canopies are the industry standard in the nation and center gutter designs are a thought of the past.

Austin Mohawk uses a perimeter gutter system that is integrated within the perimeter of the canopy to initially collect the water, our gutter system is the largest used in the industry providing better drainage and easier access for maintenance. After the water from the deckpans is collected, it then flows to tapered gutters which extend back to each column. This section of gutter actually moves the water to the columns of the canopy. At each column is either an internal drain system (PVC pipe located within the column) or an external drain which uses a collector box.

Austin Mohawk designs each canopy for the specific site location and accounts for the wind and scannow loads required by code.  Our PE (professional engineer) dictates what drainage criteria should be used based on the region and code requirements.

Code also requires canopies to have a secondary drainage system which is met by the use of scuppers in the perimeter gutter. Scuppers are used as the secondary emergency drainage system; the size and number of scuppers are determined by the PE based on his calculations of the canopy layout, square footage, and geographic requirements.

To provide adequate drainage on your canopies it is imperative to have drains at all columns. If there is a site condition that would require a change in this standard Austin Mohawk should be provided these parameters at the time of quote and drawing request as custom requirements can affect steel layout, structural deck attachment direction and custom gutter systems thus affecting your cost and the drawing details. Insufficient drainage can result in void of warranty and longevity of the canopy product materials.
