The structure and performance of different types of bridges are different, which makes them have different requirements when they are used. So what are the thickness requirements when the bridge is installed?

The minimum plate thickness of the bridge is allowed: when the width of the bridge is B <100mm, the thickness of the plate is 1.0mm; 1.2mm when 100≤B <150; 1.5mm when 150≤B <400; 2.0mm when 400≤B≤800; 2.5mm when B≤800 mm.

Cable tray width ~ minimum allowable plate thickness Cable tray width <100 ~ 1 100≤ Cable tray width <150 ~ 1.2 150≤ Cable tray width <400 ~ 1.5 400≤ Cable tray width <800 ~ 2800 <Cable tray width ~ 2.5 Cable trench cover Boards, cable trays, cable supports, meter boxes, extruded profiles, etc.

Bridge body thickness: B (bridge width) less than 100mm thickness 1.0mm; B greater than or equal to 100mm less than 150mm, thickness 1.2mm; B greater than or equal to 150mm less than 400mm, thickness 1.5mm; B greater than or equal to 400mm less than 800mm, The thickness is 2.0mm; when B is greater than 800mm, the thickness is 2.5mm.
