Reasonable value of design new develop gutter configuration:

- consistently safe and strong- durability- cheapness- ease of fixing

Which often comes down to three decision:- domestic/ commercial,- aesthetics- long light prediction.

An exiting range gutter needs to install and remove the condensation tray, shown in Fig.1.

Step 1: We estimated the person who went over the gutter which is about 200 [kg] weight at the center point of the gutter. The load of the gut-ter comes from the roof reaches to 100 [kg].

*3. ANSYS Structural Analysis3.1 Boundary Condition

Step 2: We applied 150 [kg] of concentrated load at the end of gutter (over the pillars).

Application of correct shapes of gutters can help to restrain the durability and life prediction of the gutter to get to receiver side.

A good match was found between the measured and predicted profiles model (G).
