What is the reason why the actual pole size of high pole lights is often too small? solar street light-liter

Can the insertion depth of each section of high pole lights be controlled at 50 cm? The answer is yes, it is really out of control. From production to installation, high pole lights need to face many links that affect the assembly size, such as rolling rods, calibration, hot-dip galvanizing, welding, transportation, etc. These links will affect the final product to a greater or lesser extent. The insertion depth, that is to say, the insertion depth is designed to be 50 cm when the drawings are designed before production, and it may be 40 cm or 70 cm during the actual installation. This is entirely possible. This is also the main reason why customers have misunderstandings about high-pole light manufacturers. When many customers accept high-pole lights, the measured dimensions do not match the drawings. This phenomenon is most prominent on high-pole lights above 30 meters, because 30 High pole lights above meters are composed of at least three to four sections. Take four sections for example, the four-section pole section will have three insertion points, if the error of each insertion point is 40 cm (some even higher) , then the three sections are added together to be 1.2 meters, which leads to the final height will be lower than the drawing requirements, but households will mistakenly think that the manufacturer is cutting corners, in fact, the insertion error is large, resulting in too deep insertion
