Project scope
44 balconies across several buildings.
- average of 6 linear metres of railing per balcony
- approximately half of the elements taken over for repair
- remaining railings manufactured from new
- condition assessment, measurement and repair specification
- removal, transport and reinstallation
Engineering challenge
Corrosion before project handover.
The previous contractor’s components had not been adequately protected against corrosion. They were painted without prior galvanising, and rust appeared before the development was accepted.
Some defective elements had already been installed, so the repair scope also required controlled removal.

Delivery process
From failure diagnosis to durable corrosion protection.
Assessment
Identification of the corrosion cause and development of a repair method.
Removal
Safe removal of installed elements and preparation for refurbishment.
Blasting and galvanising
Removal of the old coating and application of appropriate corrosion protection.
Coating and installation
Graphite powder coating, transport and reinstallation.
Outcome
Consistent appearance with the correct protection system.
Silma manufactured the remaining railings from carbon-steel sections with galvanised wire-mesh infill.
Both the sections and mesh were galvanised and then powder coated in graphite. The completed scope was accepted by the developer without further corrosion issues.
