Street Lighting
CMT’s Structural Investigation Division offer effective proven on-site inspection and testing services to the street lighting industry that cover all areas identified in the new TR22 Third Edition 2007, as being at risk. Testing is routinely confined to zones of high stress that coincide with areas at greatest risk of corrosion although all other elements can be included if required.
The unique Relative Loss of Section™ systems were developed specifically to locate and quantify corrosion of steel columns that cannot be identified by visual inspection. i.e. Internal and external surfaces of the buried section of the root, and internal corrosion of the base and hot swaged joint.
The RLS technique is a dry coupled system that will provide a cost efficient assessment of the column. The results obtained estimate the percentage loss of section allowing the columns to be classified (1 to 5) for either replacement or retesting at a scheduled interval (See table below). An electronic reporting procedure enables test results to be downloaded directly into the client’s inventory.
CMT is UKAS accredited for the use of the RLS™ system and is currently the only organisation accredited for structural testing of steel lighting columns. For a complete cost-effective inspection and testing service that has been employed by many authorities and contractors in the UK and overseas, then CMT has to be the obvious choice.
Services offered include:
- Detailed structural inspection (concrete and steel)
- Loss of section monitoring
- Hot swaged joint assessment
- Ultrasonic testing
- Magnetic particle inspection
- Load testing of flange plate bolts
- Half-cell potential
