30m Lightning Protection Tower
The 30m lightning protection tower is a free-standing steel mast that stands taller than the equipment it protects. The body reads as a narrow tapering trunk, wide at the base for anchor bolts and slender at the top where the air terminal sits. Every steel part is hot-dip galvanized before shipment, so no field painting is needed. The tip is a tin-coated steel pipe, chosen because tin sheds moisture better than bare zinc in wet coastal air.
Components
A built 30m lightning protection tower splits into four to six shipping tiers, so each section fits inside a 12 m trailer:
Four-leg angle steel main body (GFL) or tubular pole (GH)
Galvanized round-steel cross arms holding the air terminal
Base plate and anchor bolts sized for 100 kN/m² or 200 kN/m² soil bearing
Climbing ladder with a rest platform for annual inspection

Product Advantages
A fixed tower removes the need to lift a separate mast onto every rooftop. Field crews stand the tower in two days once the concrete foundation has cured, and the rigging hardware reuses on later projects. We also supply the base anchor bolt template so your civil crew sets bolts level on the first pour. The tapering trunk lets wind pass through with less drag than a solid pole, which cuts the anchor load on exposed hilltops.
FAQ
Q: Can the same 30m lightning protection tower protect a 20 m tall refinery unit?
A: Yes. We run the rolling-sphere calculation with your strike class and unit height, then confirm the protection radius covers the whole roof.
Q: What foundation do I need?
A: A reinforced concrete pad sized for the soil bearing value from your geotech report. We supply the anchor bolt layout and embedment drawings.
Q: Do you provide installation abroad?
A: We ship members and dispatch a supervisor. Local riggers do the bolting; our engineer checks verticality and grounding bonds at handover.
