How Deep Is Commercial Guttering?

Gutter Materials

• Gutters for industrial applications can be made of galvanized steel, aluminum, and sometimes stainless steel, although galvanized steel is the most common. Aluminum is used in coastal areas to prevent corrosion, although it fluctuates due to temperature changes. In areas with wider temperature fluctuations, steel is preferred since it expands and contracts less than aluminum
  
  

Gutter Depth Calculations

• The needed depth of an industrial gutter depends on the total area of the roof, the slope of the roof, and the rainfall intensity. Copper.org gives a formula using the plan area, design area, downspout area, and rainfall intensity to determine downspout size and gutter size.
  
  

Keeping Gutters Clean

• Regardless of the depth of the gutter, it is important to keep them clean and free of debris. A clogged gutter can cause water to run down the outer walls of the building and cause water damage. Blocked drainage pipes can also leach water under the foundation of the structure.
