Street & Floodlight NDT

Street Lighting NDT Inspection Services 

WHE NDT provides Non-Destructive Testing (NDT) inspections for street lighting columns and associated structures, helping asset owners manage safety, compliance, and lifecycle costs.

Street lighting assets are exposed to corrosion, fatigue, and environmental damage. Our inspections identify hidden defects before failure, reducing risk to the public and supporting informed maintenance decisions.

Why Street Lighting NDT Matters

• Prevent sudden column collapse

• Identify internal corrosion and wall loss

• Support highway authority duty of care

• Reduce unnecessary replacement through condition-based maintenance

• Provide independent inspection evidence for audits and insurers

Inspection Techniques

Our inspection methods are selected to suit column type, material, age, and environment, and include:

• Ultrasonic Thickness Testing (UT)
  Measurement of wall thickness to identify internal corrosion and material loss, particularly effective at ground line and door aperture zones.

• Magnetic Particle Inspection (MPI)
  Detection of surface and near-surface cracking on ferromagnetic components such as base plates, welds, and brackets.

• Visual Inspection (VT)
  Assessment of external condition, corrosion, deformation, impact damage, and fixings.

• Targeted Weld Inspections
  UT or MPI of critical welds where deterioration or cracking is suspected.

Applications

• Highway and local authority street lighting

• Car parks and public realm lighting

• Industrial estates and commercial sites
