The main advantage in using the LOKRING® method is that it eliminates the need for hot works at height in a refinery environment or offshore.

Guy Wire Services

Zenith provides a comprehensive guy wire service for structures such as flare stacks, steel chimneys and masts. In addition, we specify and supply complete guy wire requirements.

Our dedicated team of fully qualified inspection engineers also facilitate all on-site access requirements throughout the full length of the guy wires. Following the survey, all of the information obtained is fed back to our Structural Engineers who compile detailed inspection reports complete with recommendations.

Please refer to the list below for our full range of guy wire services:

• Inspection
• Maintenance & Repair
• Dismantling
• Lubricating
• Retention
• Supply and Replacement
• Verticality
• Magnetic Inspection (LMA and LF)

Magnetic Inspection (LMA and LF)

Of particular note is our Magnetic Inspection (LMA and LF) service. Electromagnetic tests provide valuable additional information on the condition of wire ropes and are regarded as a useful addition to the visual inspection, particularly, where difficult access precludes a meaningful visual survey. The permanent magnets induce a magnetic field around the rope, any defect within the wire rope creates a stray field, and this is detected and recorded on the data logger.
