Steel Structure Inspection & Restoration
AGING STEEL INFRASTRUCTUREOnce thought to be permanent structures free from maintenance and concerns, steel towers and poles have demonstrated that they do indeed degrade over time as a result of corrosion and mechanical damage.
Osmose inspection and maintenance programs are designed to help de- tect, repair, and prevent corrosion on steel towers, poles, anchors, and other steel structures and their foundations. Accurate inspections, effective mitigation methods, and structural repairs designed to re- store strength help electric utilities:
Extend the service life of steel towers and poles
Improve system reliability
Reduce emergency and unscheduled costs
Alleviate premature replacement of structures and subsequent replacement costs

RESTORATION DESIGN & INSTALLATIONOsmose provides turnkey engineered solutions for damaged steel towers and poles at a fraction of the cost of replacement. Whether the structure is direct-buried, on concrete foundations, or in water, structural repairs are designed to meet customer requirements. These repair solutions not only restore strength, in many cases, they can increase capacity if greater strength is needed.
MITIGATION: EFFECTIVE COATINGS & CATHODIC PROTECTIONBy applying corrosion mitigation counter-measures, such as protective coatings and cathodic protection, Osmose can help extend the useful service life of steel structures. Osmose provides turnkey mitigation design and installation for various types of transmission structures and environmental conditions.
Application of coatings below grade is the primary method of protection for most buried steel structures.
Cathodic protection systems are most often used as a secondary form of mitigation. At-tachingsacrificialanodestosteelstructuresand placing them in the same soil provides an additional layer of corrosion mitigation.
