Steel Pole Advantages Less right-of-way Better appearance Less components, fast installation Better reliability under extreme conditions Flexibility in design Reliable performance and long service life

Less Right-of-way Smaller foundation takes less land Efficiently placed along highways, roads, rail tracks Can be installed at locations with very limited space

Better Appearance Trend of city beautification –Remove visual pollution –Need structure compatible with environment –Bulky clutter lattice tower visually unpleasant 85% public prefer poles over lattice towers

Better Reliability under Extreme Condition Steel monopoles are more flexible than lattice towers, concrete or wood pole under heavy loads In broken conductor case, bigger deflection of the steel pole reduces tension in intact span and induces smaller bending moment at base Round or multi-side profile induces less wind load In past cases where lattice towers and wood poles failed in hurricane and tornado, no steel poles were damaged

Flexibility in Design Various structure configuration – monopoles and frames Different voltages and circuits on same pole Distribution under-built Multiple circuits in different orientation Adding lines for telephone, cable TV

Steel poles shapes Configuration - single pole, H-frame, Y- frame, X-frame, 3-pole structure

Steel poles connections available between sections Sections connections – slip joints, flange joints, butt welded joints

Steel pole foundations options Foundation types – concrete foundations with anchor bolts, direct embedded, caisson foundations

Steel poles finishes Surface protection – galvanizing, weathering steel, powder coating over galvanizing
