Pre-engineered polygon structural masts equipped with automated dual-drum raising-and-lowering gear, IP67 LED optics, and heavy-duty marine hot-dip galvanization designed specifically for Bangkok municipal corridors, port facilities, and airport aprons.
Standardized for Bangkok Expressway interchanges (EXAT) and urban ring roads with internal motorized winches, fall-arrest mechanisms, and dynamic wind deflection control.
Heavy-duty 25m–40m apron and container terminal towers, engineered for Laem Chabang and Bangkok Port with C5-M marine anti-corrosion barrier coatings.
High-output asymmetrical optical floodlighting with cross-arm head-frames, customized targeting matrices, and zero-flicker broadcast compliance for Thai municipal athletic venues.
Modular high-lumen solar floodlighting for suburban logistics parks, toll plazas, and remote transport bypasses without expanding the Bangkok municipal power grid.
Designing high-elevation lighting infrastructure for Bangkok requires rigorous structural consideration of quaternary soft marine clay, monsoon-induced aerodynamic vortex shedding, and high-salinity industrial microclimates.
The Bangkok basin rests on thick, compressible marine clay characterized by undrained shear strength as low as 10–25 kPa in the upper strata. Installing 25m–40m high mast towers requires deep cast-in-place bored piling reaching the lower stiff clay or dense sand stratum at 22m–36m depths.
Thailand's Department of Public Works and Town & Country Planning (DPT 1311-50 standard) prescribes strict design wind loads. Masts across the Bangkok plain must absorb severe squalls, monsoons, and thermal vortex shedding without second-mode harmonic resonance.
Operating in Bangkok's tropical savanna climate entails 80%+ average relative humidity, high ambient heat (+40°C), and chemical/saline fallout from the Gulf of Thailand and Chao Phraya petrochemical zones (Samut Prakan corridor).
Global contractors managing expressway bypasses, airport terminal aprons (Suvarnabhumi Phase 2 & 3, Don Mueang), and Eastern Economic Corridor (EEC) freight nodes require rigorous quality verification, traceable raw materials, and factory-direct pricing without distributor overheads.
High mast towers demand precision telescopic slip-joint fabrication. Transporting 20m, 30m, and 40m masts requires segmented modular designs engineered for standard 40ft High Cube (HQ) and Open Top (OT) shipping containers. Sourcing from our 100,000 m² Gaoyou production facility allows direct breakbulk or containerized dispatch via Shanghai/Taicang port to Bangkok Modern Terminal (BMT), Khlong Toei Port, or Laem Chabang Deep Sea Port within an economical 7 to 11 days ocean transit time.

A high mast installation is an integrated structural and electro-mechanical system. Failure of the winch gear, latching mechanism, or thermal management directly jeopardizes public safety across mission-critical transport nodes.

Ground-level maintenance eliminates the danger and expense of hydraulic cherry pickers or cranes on busy highways. Our R&L mechanism utilizes:
Urban light pollution and glare are heavily restricted around Bangkok's international airports (ICAO Annex 14) and dense expressway interchanges:
Ambient ground temperatures in Bangkok often reach 42°C, with solar absorption driving luminaire housings past 65°C. Unmitigated heat degrades LED lumen maintenance and causes driver failure:
Public infrastructure procurement in Thailand requires unyielding adherence to national electrical and civil safety codes. Our high mast product series are pre-engineered to align seamlessly with regional submittal guidelines.
Compatible with MEA (Metropolitan Electricity Authority) in Greater Bangkok and PEA (Provincial Electricity Authority) networks in surrounding EEC industrial provinces:
Every mast shaft undergoes full non-destructive testing (NDT) to prevent catastrophic weld cleavage under persistent tropical monsoons:
The transition toward the "Thailand 4.0" framework has converted standalone high mast structures into multi-functional IoT communication nodes supporting intelligent traffic systems, air quality monitoring, and adaptive energy management.
Cellular and sub-GHz mesh wireless modules embedded in high mast crowns transmit luminaire diagnostics, power factor anomalies, and runtime logs to municipal control centers without dedicated signal trenching.
Integrated DALI-2 and 0–10V smart drivers dynamically adjust illumination levels based on real-time transit density, reducing energy draw by 35% to 55% during low-traffic overnight windows.
Tri-axial MEMS accelerometers and inclinometers mounted at the top shaft detect deflection spikes, base settling, or high-amplitude wind oscillations, triggering predictive maintenance alerts prior to structural fatigue.

Because Bangkok's upper clay layer (top 12m to 15m) possesses extremely low shear strength, shallow pad footings cannot withstand the heavy overturning moment generated by 25m–40m high mast towers. We provide project structural engineers with complete base moment, vertical axial load, and horizontal shear load calculations (reactions at mast base). Foundations are typically detailed for deep cast-in-place bored piles (600mm to 1000mm diameter) resting in the stiff clay or dense sand stratum at 24m to 35m depth, anchored via high-tensile Grade 8.8 / 10.9 steel anchor cages with rigid top and bottom positioning rings.
We engineer to Thailand's national standard DPT 1311-50 ("Standard for Wind Load Calculation and Response of Buildings"). Basic reference wind speeds in the Bangkok Metropolitan Region typically range between 27 m/s and 30 m/s (approx. 108 km/h sustained wind with gust velocity coefficients up to 140–160 km/h depending on terrain exposure category B or C). Our finite element modeling enforces a strict dynamic deflection threshold (< 1/40 of the total structure height) to prevent luminaire optical misalignment and metal fatigue during tropical squalls.
Our masts undergo full-immersion hot-dip galvanizing inside and out in accordance with ASTM A123 and ISO 1461. For coastal and estuary installations along the Gulf of Thailand, we specify a minimum average zinc coating thickness of 100 µm to 120 µm. Furthermore, we offer a duplex protective system combining hot-dip galvanizing with an electrostatic polyester/polyurethane powder coating (80–120 µm) cured at 200°C. All lifting wire cables, pulleys, and external hardware are manufactured from AISI 316 marine-grade stainless steel.
The raising and lowering system is built with fail-safe redundancy. First, the internal winch features a dual-drum self-locking worm-and-gear transmission that mechanically prevents reverse slippage without power. Second, when the luminaire ring reaches the tower masthead, an automatic mechanical gravity-latch mechanism engages solid steel hooks into structural docking slots. Once latched, all operational static tension is removed from the stainless steel hoisting ropes, ensuring the ring cannot descend even in the event of cable failure.
Yes. Our in-house lighting engineering team generates tender-ready DIALux Evo photometric studies based on your exact CAD site geometry, target lux requirements (e.g., 30 lx, 50 lx, 100 lx average), and uniformity ratios (Uo ≥ 0.40). We calculate isolux contour plots, 3D pseudo-color renderings, glare ratings (GR < 50 for port yards, UGR < 22 for roads), and schedule exact luminaire cross-arm aiming angles, complete with certified IES/LDT photometric files.
Production typically takes 20 to 30 working days depending on order volume and custom requirements. Telescopic mast segments are designed with precise slip-joint overlaps (1.5 times the mating diameter) to pack flat inside 40ft HQ or Open Top ocean containers. Containerized or breakbulk vessels depart from Shanghai or Taicang ports and arrive at Bangkok Port (Khlong Toei) or Laem Chabang Port within 7 to 11 days. Complete export documentation, packing lists, and Form E preferential certificates of origin are provided.
Yes. Tropical thunderstorms across the Chao Phraya basin produce heavy transient lightning strikes. Every high mast floodlight fixture is equipped with an integrated 10kV surge protection device (SPD) within the driver, augmented by an additional 20kV external lightning surge arrester in the base distribution terminal cabinet. Each mast is topped with a solid copper lightning air terminal rod grounded to the earth rod network (< 10 Ohms impedance).
We provide a 20 to 25-year structural warranty on the hot-dip galvanized steel pole shaft against perforation corrosion, and a 5 to 10-year comprehensive warranty on LED luminaires and driver power units. Our engineering department provides step-by-step 3D assembly animation manuals, slip-joint hydraulic pulling instructions, and remote video commissioning support during foundation erection and winch testing.
