Maintenance – Steelworks

Zenith has a wealth of experience in this essential field of activity. We have decades of experience in the maintenance and repair of structures across steelworks including industrial chimneys, natural draught cooling towers, flares and other tall structures.

Maintenance & Repair

Zenith specialises in carrying out repairs throughout all industrial, commercial and residential sectors. We provide all of the trades and skills required to maintain and repair buildings and structures. We work for the world’s leading companies ranging from petrochemical, power, steel and cement to academia, hospitals, local courts and much more.

Maintenance – Industrial Chimneys

The inspection, maintenance, repair and demolition of industrial chimneys remains our core activity. The successful external and internal refurbishment of these structures requires a thorough survey to establish the true extent of the repair work required. A full digital survey is the first stage in a five-phase operation that includes access equipment design, installation, load testing and repairs. We offer an online hot camera inspection as digital photography can reveal weaknesses and defects that require attention, for example to the interior lining and brickwork, baffle walls and flue inlets. Critically, it also enables engineers to plan in advance of a shutdown.
