Hot Galvanized Round 20 M Steel Electric Utility Power Transmission Tower Monopo Hardware 4mm for Power Distribution

 Specification:

 Descripition of material:

 1. Poles are made by the high-quality metal plants,which were molded into the multi-row cone-shaped  vertical steel barwith hot galvanized anti-corrosion treatment
 2. Light plate frame is made by high-quality stainless steel
 3. Fastened bolts and nuts of stainless steel

 Normally   Q345B/A572, Minimum Yield Strength ≥ 345 N/mm²
                  Q235B/A36, Minimum Yield Strength ≥ 235 N/mm²
 As well as Hot rolled coil from ASTM A572 GR65, GR50, SS400

Some of the advantages of steel poles over wood poles are as follows:

Lighter - steel poles are significantly lighter than wood poles

More consistent - steel poles do not vary in dimension

Longer service life – steel poles are not vulnerable to insects, woodpeckers or other wildlife

Cost competitive – steel poles are becoming much more affordable as an alternative to wood

Recyclable – steel poles are recyclable after their service life

Different appearances - steel poles are available painted, with a traditional galvanized finish, or in weathering steel

With the advantages of steel, utility companies continue to rely on steel distribution poles in place of wood.

 Welding:

 Advanced submerge-arc welding and CNC welding equipment. It has past flaw testing, internal and  external double welding makes the welding beautiful in shape. It confirms with the international welding  standard of CWB and AWS D 1.1

 
 Galvanization
 Standard:NFA91121
 Average thickness of the galvanization:Not less than 86μm.

 Installation
 - Remove all the equipment on the pole during Assembly.
 - Circle a sling around th epole shaft of each section.
 - Fix the sling on top section to one pulley block.
 - The sling on the bottom section is tightly fixed and fixed at the center of gravity.
 - Make the steel pole vertical by tighten the sling of the top section.
 - Fix the steel pole.
 - Remove the sling.
