Choosing the right diameter strut is important for safety and ensuring the gas strut won't bend or break.
We generally recommend the diameter of the gas strut based on 3 important factors of a project:
Length
Width
Weight
When we do a design for any new project we take into consideration all of the above factors.
For instance if we were doing a window that was 1200 high and 1800 wide we would not recommend a 8/18 diameter gas strut as it would be more likely to bend due to the height and width of the window.
Our General Use Gas Struts come in the follow diameter
6/15 Diameter
Maximum length: 500mm - Maximum force: 400N
8/18 Diameter
Maximum length: 175mm - 750mm - Maximum force: 700N
Maximum length: 800mm - Maximum pressure: 500Nm
10/22 Diameter
Between length: 195mm - 730mm - Maximum force: 1200N
Maximum length: 1200mm - Maximum force: 1000Nm
14/28 Diameter
Maximum length: 195mm - 730mm - Maximum force: 2200N
Maximum length: 750mm - 940mm - Maximum force: 2000N
Maximum length: 1100mm - 1200mm - Maximum force: 1800N
