4 light pole technology reference

1. The main body is made of a forming, steel bar (Q235) weld must level off is smooth, the weld

Convex part and the error of leveling rod body should be no greater than + / - 1 mm. Light pole welding method for automatic arc welding, coloring flaw detection of welding international GB/T3323-1989111 standard requirement. Light pole socket means using nail and wire fixation.

2, anti-corrosion treatment for hot dip galvanized, light pole. The galvanized layer surface is smooth and beautiful, luster. Not wrinkled skin, flow drop and zinc tumor, peeling, spots, surface defects of Yin and Yang, the zinc layer thickness reach more than 85 um, galvanized layer adhesion should meet GB2694-98 standard, guarantee the 8 years do not fade, light pole according to 36.9 m/s wind resistance design. Light pole anti-corrosion life more than 20 years.

3. ≧ 100 um light pole surface coating thickness, adhesion to GB9286-880 level, smooth surface, hardness ≧ 2 h, using outdoor weatherability material, coating material for the polyester molding powder.

4. Light pole technology and acceptance standard execution according to the national standards. Design coefficient of 1.8. Light pole design life is more than 20 years.

5. Design should facilitate wire wear light pole, hand hole door adopt backpack door form. Bar the door must level off is smooth, with this cue level error is not more than + / - 1 mm, the same light pole from door to door better interchangeability, meet the requirements of security rainproof. Bar the door local do after cutting, the strength of the basic in the whole bar.

6. Color: the color specified by the owner. (color) rendering
