Box Gutter Depth
With 1 gpm 0 063 l s flow rate.
Box gutter depth. For box gutter depth any equation incorporating flow depth and width will do. Have a minimum depth of 75mm at the high end. The usual nomenclature applies q flow w width y depth. Our 6 box commerical gutter is fabricated from 032 kynar 500 aluminum.
These gutters are commonly seen in commercial and industrial applications but are also used in homes for a more clean and modern look. If a roof s various drainage areas call for different size gutters go for the biggest one k style. It may be lined with epdm rubber metal asphalt or roofing felt and may be concealed behind a parapet or the eaves or in a roof valley. The box gutter depth and the sump length are influenced by the size of the overflow.
5 inch 5 520 square feet. Plumbing codes typically use the vertically projected roof area for drainage design and they often use a square foot allowance per square inch of downspout for 1 in hr 25 mm hr rainfall that varies with diameter for example 3. Downspouts and gutters are sized in relation to rainfall on this basis. The best and simplest is the critical depth equation.
6 inch 7 960 square feet. Have a minimum width of 300mm for commercial installations 200mm for domestic installations. The most important point of this section is that you cannot reduce the size of the box gutter to exit the building so we advise keeping the box gutters between 200mm and 300mm wide. At k m sheet metal and gutter supply we offer box gutters in several profiles since these are bent on a brake.
Normally offered in 10 and 20 we can actually bend such profiles in up to 21 lengths. Have a sole width which is not reduced discharge at the downstream end without box gutter design. A wider overflow needs less depth of overflow hence the box gutter depth will also be reduced. Multiply the drainage area by the roof pitch factor and rainfall intensity to find out the adjusted square footage.
However a wider overflow may increase the length of the sump. Suffix 1 represents the base condition to be scaled and suffix 2 the scaled result. A box gutter internal gutter parallel gutter or trough gutter is a rain gutter on a roof usually rectangular in shape. The width of the rainhead is to be at least equal to the width of the box gutter and the box gutter needs to.
Architects around the world specify kynar finishes since no other coating withstands the rigors of nature and time like those based on the kynar 500 resins. Making the box gutter wider will also reduce the box gutter depth. Critical depth occurs near the outfall of every box gutter. Depth of the box gutter consistent with saa hb39 installation code for metal roof and wall cladding section 5 clause 5 7 3 and figure 5 7 3 to prevent internal flooding or damage to the building or contents see figure 2.
Modifications such as roof flanges are common on custom profiles.
