Octagonal Tapered Steel Monopole Tower Hot Dip Galvanized Flange Bolted For 5G Telecom Antenna

A steel monopole is a single self-supporting tubular steel pole carrying telecom antennas or power conductors on one vertical structure. This octagonal tapered monopole is formed from steel plate into a polygonal conical section, seam welded along its full length, and delivered in transportable segments that are joined on site with bolted flange connections. Every pole is hot dip galvanized after fabrication, producing the uniform silver grey zinc finish that buyers recognise on telecom monopole towers and galvanized utility poles worldwide. Because the structure is engineered to the project rather than to a fixed catalogue size, height, plate thickness, section shape and accessory layout can all be adapted to the load case, the antenna configuration and the local wind code.

• Octagonal faces give flat mounting surfaces, so antenna brackets, RRU mounts and microwave dish adapters sit flush without shimming
• The tapered conical profile keeps the top diameter small, reducing wind load and visual bulk in urban and suburban sites
• Polygonal sections resist local buckling better than thin round tubes under the same plate thickness
• Flange bolted joints are factory drilled and match marked, so site work is bolting only, with no field welding and no hot work permit
• Internal stiffener diaphragms at each flange transfer bolt load into the pole wall and control ovalisation under high wind
• Pre-formed cable entry holes and internal cable routing keep feeders protected and the external appearance clean
• Hot dip galvanizing to EN ISO 1461 or ASTM A123 gives predictable zinc coating inside and out, including the inaccessible internal surfaces

The values below are reference ranges used for preliminary sizing only. Final dimensions are engineered against the actual antenna load, wind speed and governing design code, so please treat them as indicative rather than fixed.

Used as a 5G or 4G antenna pole for macro sites, rooftop installations, small cell densification and rural coverage. The single pole footprint is small, which matters where land acquisition is difficult, and the polygonal shaft carries multiple antenna sectors plus microwave transmission equipment on one structure. Where planning authorities require it, the same structure can be detailed as a camouflage monopole with cladding or a tree canopy.

Used as a steel pole for overhead lines in the low and medium voltage range and up to subtransmission levels, typically discussed in the 10 kV to 220 kV band. Compared with wood and concrete poles, a galvanized steel pole is dimensionally consistent, lighter to handle, free from rot and insect attack, and easier to maintain over a long service life. Single circuit and double circuit arrangements, cross arms, insulators and climbing steps are all integrated at the fabrication stage.

Every monopole we fabricate is a custom structure. That means the starting point is your drawing, your antenna schedule or your line loading table rather than a standard product list. Where the buyer has site data but no drawing, we work from height, wind speed, antenna count and weight, and the required design code, and return a proposal with recommended dimensions for review.

• Fabrication from buyer drawings, or design support from site parameters
• Shop drawings and approval drawings issued before production
• Material certificates, galvanizing thickness report and dimensional inspection report supplied with the shipment
• Third party inspection such as SGS, BV or TUV can be arranged on request
• Section lengths planned around container and trailer limits, with flange faces protected and bolt sets packed separately
• Trial assembly of joints before shipment is available for multi section towers

Is a monopole better than a lattice tower? For a single operator site with a small antenna load and tight land, a monopole is usually simpler to permit and faster to install. Lattice towers remain more economical for very tall structures or heavy multi operator loading. Both are available.

Can one design serve both telecom and power use? The fabrication process is the same, but the design basis differs. Telecom poles are governed by antenna load and wind induced vibration, power poles by span, conductor tension and clearance. Tell us the intended use and the design is carried out accordingly.

What about lead time? Lead time depends on height, quantity and whether approval drawings are required. Small orders typically move faster than multi section engineered towers. Share the scope and a schedule will be confirmed.

Can the pole match an American or Australian standard? Yes. Material, welding and galvanizing can be aligned to AISC, AS/NZS and EN requirements where specified in the enquiry.

To receive a tailored proposal, please share the pole height, intended use, antenna or conductor loading, design wind speed, governing code and quantity. With those points a technical proposal and commercial offer can be prepared against your project rather than against a generic catalogue figure. Drawings in PDF, DWG or DXF are all acceptable.
