Greater Noida lightning protection: define the requirement before choosing a product
Discuss your site with SN Engineering from its Gurgaon contact office. For Greater Noida, specify whether you need air-terminal supply, a design review, installation, testing or a combined project scope. This guide explains the information needed to compare a lightning protection proposal.
Large sheds and changing roof profiles
For a Greater Noida shed, warehouse or logistics project, provide overall dimensions, ridge and eaves heights, roof extensions, loading canopies and rooftop equipment. Large roof areas need method-specific drawings and measured routes for a usable BOQ.
Roof interfaces and installation sequencing
Identify fragile roof areas, waterproofing details, conductor fixing arrangements and the civil-work schedule. Confirm approved fixing details and access before supply so the installation does not depend on an unreviewed roof penetration.
Components to identify in the quotation
| Component | Selection and quotation details |
|---|---|
| Air-termination system | Conventional terminals, mesh or masts, or a specified ESE model where accepted by the project. Identify the design method, mounting arrangement and protected-zone drawing. |
| Down conductors and fittings | Specify conductor material and dimensions, measured routes, supports, compatible connectors, guards and accessible test joints. |
| Earth termination and bonding | Define electrodes or ring/grid arrangement, connections, inspection points, material compatibility and the relationship to the existing earthing system. |
| Surge protection | Identify the power and signal services requiring protection, SPD selection and coordination, installation locations and connection details. |
| Inspection and handover | State inspection scope, continuity and earth-testing records, equipment/calibration identification, as-built drawings and maintenance instructions. |
Conventional and ESE proposals
For conventional lightning protection, ask for the selected air-termination method and the drawing showing roof coverage, conductor paths and bonding. For an ESE lightning arrester, identify the exact model, declared ΔT, test basis, installation height and the project acceptance requirements. The two approaches should be compared on their stated design basis.

Documents to check before order and at handover
Request the datasheet for the exact model offered, relevant test documents and a drawing showing the design basis. A test report for a different model, or a general company certificate, does not establish the performance of the proposed item.
For installation handover, agree dated site photographs linked to drawing references, conductor and bonding inspection records, test-point identifiers, the measurement method and instrument details, and as-built drawings. A preliminary design assessment is different from a signed record of completed installation and measured site results.
Installation, testing and maintenance scope
Agree the inspection points before work begins. The commissioning scope should cover the installed air-termination layout, conductor and bonding continuity, earth connections, accessible test joints and any SPDs included. Record the test method and results rather than relying on an unqualified target resistance figure.

Buyer questions
What affects the quotation for a large warehouse roof?
Roof area and levels, design method, conductor routes, mast supports, earth termination, access equipment and testing scope all affect quantities. A quotation based only on floor area is provisional.
How is lightning arrester price worked out?
Compare the exact air-terminal model, mast/support arrangement, conductor material and quantity, earthing and bonding scope, SPDs, access equipment, installation, testing, taxes and freight. Request a written itemised quotation; model-only prices do not describe a complete installed system.
Can one lightning arrester protect any building?
Selection requires the building dimensions, roof levels, equipment projections, design basis and protected-zone drawing. There is no universal coverage radius suitable for every project.
