We offer two types of lightning protection systems for commercial and industrial structures.
The ERICO SYSTEM 2000 includes an engineered series of air terminals, downconductors and fittings in accordance with European-IEC 62305 and USA-UL96 and NFPA780 Standards. As industry leaders, Bonded Lightning Protection is specialized in handling and installing the Erico System 200 on Commercial and Industrial structures.
ERICO is a leading global designer, manufacturer and marketer of precision-engineered specialty metal products serving niche markets in a diverse range of electrical, construction, utility and rail applications.

The Six Interdependent Disciplines that form a Protection Plan are:
1. Capture the lightning strike
2. Convey this energy to ground
3. Dissipate the energy into the grounding system
4. Bond all ground points together
5. Protect incoming AC power feeders
6. Protect low-voltage data/telecommunications circuits
There is no known method of preventing the occurrence of a lightning discharge. The purpose of a lightning protection system, therefore, is to control the passage of a discharge in such a manner that prevents personal injury or property damage. The need to provide protection should be assessed in the early stages of the structure design. Although no strict rules can be given, it is possible to use broad guidelines to arrive at the degree of protection required.
In a world of increasingly complex and sophisticated buildings and equipment, lightning is a constant risk. A single direct strike can result in physical damage to buildings and catastrophic failure of sensitive electronic equipment. It can start fires, cause major breakdowns to electrical, telephone and computer installations, and simultaneously cause substantial loss of revenue.
A thunderstorm commences with the development of a cumulonimbus thunder cloud. The cloud is typically formed by rapidly rising humid air which becomes electrified due to convection and precipitation effects. This is accompanied by wind speeds of up to 125 miles/hr. The end result is the separation of positive and negative charges (see Figure 1). In most cases, the lower part of the thundercloud is comprised of a thin, concentrated layer of negative charge, and the upper part comprises a more diffuse positively charged region. The cloud base is typically 1 to 4 miles above the ground and the cloud depth is typically 4 to 8 miles. As a result of the cloud electrification, a quasi-static electric field is established between the cloud and ground. Pointed ground objects subjected to this ambient electric field emit varying amounts of point discharge or “corona”, and the resulting positive or negative ions drift upwards to form a low density “space charge” which extends from ground to cloud.
The main lightning discharge is characterized by a rapidly rising current (averaging about 30,000 Amps) with maximum values exceeding 200,000 Amps. This whole process is extremely rapid, typically occurring within milliseconds. The average energy released in a single discharge may be 55 kW hours. The danger lies in the extremely high rate of current rise (up to 1010 Amps per second) which can generate very high voltages, and also from the continuing current following the peak. Without proper intervention to capture and control the passage of this lightning energy to ground, cloud-toground lightning can be catastrophic.
Lightning rods or air terminals are needed to capture the strike to a preferred point, and to help conduct the energy to ground to minimize the risk of damage. The number of terminals required, and their placement, is determined by the chosen lightning protection design method.
