With over 20 years of experience, we provide lightning protection, grounding systems, and integrated electrical and mechanical strut supports solutions for many of the most challenging sites in the Philippines.
When lightning strikes, an electrical field is always created at ground level and this increases in intensity as the «downward leader» approaches. Once this reaches a certain level — between 50 and 100 kV/m — the Corona effect, which develops naturally at the top of any high structure, allows discharges — known as upward leaders — to rise toward the cloud.
The position of the ionized path which will allow the lightning current to pass is determined by where the upward leader comes into contact with the first downward leader from the cloud. The sooner the rising discharge (upward leader) leaves the lightning rod to move toward the cloud, the sooner it will move closer to the downward leader and the greater the chances of the two making contact before other rising discharges from nearby high points.
It can be seen, then, that it is the start point of the first upward leader which determines the point of impact of the lightning on the ground. An early streamer emission lightning rod is designed to provide optimal conditions for the formation of this rising discharge.
An ESE (Early Streamer Emission) air terminal protects a defined radius around its tip rather than a single point. The actual protection radius depends on the terminal's triggering advantage, its mounting height above the structure, and the level of protection set by the risk assessment. A single ESE terminal can typically protect a radius of several tens of metres — we calculate the exact figure for your structure to NF C 17-102 and confirm it in the design report.
Yes. For most projects we conduct a site visit to assess structure geometry, surrounding risk factors, existing grounding, and soil conditions before finalising a design. On-site inspections are also part of our commissioning and preventive-maintenance work.
Yes. We provide scheduled preventive maintenance — visual inspection, connection and continuity checks, and periodic ground-resistance re-testing — with audit-ready documentation, on systems we installed or that were installed by others.
Yes. We can supply a complete lightning protection package — air terminals, down conductors, grounding materials, connectors, and accessories — matched to your design and required level of protection.
Yes. We handle full installation with our own trained crews, coordinated with your construction schedule and verified on completion.
Yes. You can purchase materials only. We can supply against your own design, or provide a bill of materials based on a design we prepare for you.
Our lightning protection products are manufactured to recognised international standards. Specific UL listing/certification status varies by product line — we will confirm the applicable certifications and supporting documentation for the items specified on your project.
Yes. We prepare lightning protection system designs together with the formal lightning risk assessment calculations required to determine the necessary level of protection, in line with applicable international standards.
Yes. We design facility grounding and earthing systems sized to your equipment, soil resistivity, and target resistance-to-earth, including electrode layout, bonding, and ground-enhancement measures where needed.
We provide warranty coverage on our lightning protection systems — standard coverage is 5 years, with the exact terms confirmed in your project documentation.
Our materials are sourced from established international manufacturers — including our ESE air terminals from Indelec — and supported by full technical documentation.
Performance is verified through engineered design calculations, on-site inspection of air terminals, down conductors, and bonding, and measurement of the grounding system's resistance to earth against the required threshold — documented in a signed report. Lightning strike counters can also be fitted to record activity over time.
