Electrostatic architectural polyester powder coating applied over sweep-blasted galvanized steel, delivering supreme color retention and resistance to coastal salt spray.
Every batch shipped to Turkey includes complete documentation: raw mill test reports verifying chemical composition (Carbon equivalent ≤ 0.43% for optimal weldability), mechanical yield and tensile test results, zinc coating gauge records, and non-destructive weld inspection certificates.
Contractors bidding on Turkish utility tenders require competitive landed costs, predictable maritime schedules, and fail-safe export packaging that prevents transit deformation.

How our R&D team is aligning steel pole manufacturing with modern grid digitalization, green metallurgy, and urban electrification trends.
Adopting advanced micro-alloyed structural steels that decrease total pole weight by 18-24% while increasing structural moment capacity, reducing shipping emissions and crane capacities.
Factory-prefabricated mounting nodes and wiring channels for real-time conductor temperature, line sag, and wind anemometer sensors, supporting TEİAŞ's transmission optimization.
Designing dual-purpose distribution poles with reinforced lower access chambers for 22kW-50kW EV DC fast chargers, facilitating roadside charging across crowded Istanbul neighborhoods.
Transitioning toward scrap-based Electric Arc Furnace (EAF) steel sourcing, lowering the embodied carbon footprint by up to 60% to comply with EU Carbon Border Adjustment Mechanism (CBAM) regulations.
Direct technical responses to the critical questions asked by utility project managers, EPC engineering directors, and tender procurement boards.
We use high-ductility, low-temperature impact tested structural steels (Q355B/D, S355JR/J2 per EN 10025). Our structural calculations account for Istanbul's Zone 1 seismic acceleration response spectra ($S_{DS}$ ≥ 1.5g) to ensure elastic response under design earthquakes, while base plates and anchor cage j-bolts are designed with elevated shear capacity to eliminate concrete breakout risks.
We apply a multi-barrier protection system. First, complete hot-dip galvanization per TS EN ISO 1461 / ASTM A123 delivers an average zinc thickness of 100 to 120 microns. For high-salinity zones within 2 km of the coast, we apply a duplex system featuring a degreased, sweep-blasted mechanical profile and an architectural-grade epoxy-polyester powder coat (80-120 μm) rated for ISO 12944 C5-M marine durability.
Under TEİAŞ and international ASCE 48-11 guidelines, working load deflection is typically restricted to ≤ 1.0% of the pole's above-ground height under standard operating wind conditions. For terminal strain poles or angle dead-ends, our structural engineers model finite element stiffness parameters to limit deflection to ≤ 0.5%, preventing phase imbalance or line sag issues.
Yes. We operate as an OEM/ODM direct factory. We review your municipal tender specification (TEİAŞ / BEDAŞ / AYEDAŞ Şartnamesi), conductor tension profiles, span lengths, and foundation soil parameters. Our engineering department generates customized CAD blueprints, PLS-POLE load validation tables, and fabrication shop drawings for engineer-of-record approval before metal cutting begins.
Standard factory production lead time for utility tenders (50 to 500 units) is 25 to 35 business days. Maritime transit from our Shanghai/Ningbo loading berths to Port of Ambarlı or Haydarpaşa takes approximately 24 to 28 days. Poles are nested telescopically inside one another with nylon cradle slings to protect the zinc coating and maximize container space.
All longitudinal and circumferential welds are executed by certified welders operating under ISO 3834-2 / AWS D1.1 specifications. Critical base plate-to-shaft welds and slip-joint seams undergo 100% Visual Testing (VT), Magnetic Particle Inspection (MPI), and Ultrasonic Testing (UT) to ensure complete penetration and zero internal voids before the structure enters the galvanizing kettle.
