Steel is the backbone of many building structures — from reinforcement bars (rebar) inside concrete to exposed beams, columns, and fixings. Over time, exposure to water, chlorides, and atmospheric pollutants initiates corrosion, causing loss of cross-section, reduced load capacity, and in reinforced concrete, cracking and spalling of the surrounding material.
Left untreated, corrosion can spread aggressively, leading to costly structural damage, compromised safety, and in severe cases, complete component replacement. Atomic Projects approaches steel corrosion not just as a cosmetic fix, but as a structural restoration task — stopping the current damage, reinstating strength, and installing long-term barriers against recurrence.
Our Process for Steel Corrosion Treatment
- Condition & Cause Assessment
- Survey steel elements for pitting, surface rust, and deep section loss.
- Identify moisture ingress points, galvanic reactions, and environmental contributors.
- Conduct cover depth testing and chloride analysis for embedded steel.
- Preparation & Access
- Isolate and make safe the work area.
- Remove surrounding finishes, coatings, or concrete to expose the full extent of corrosion.
- Corrosion Removal
- Employ mechanical methods (grinding, abrasive blasting, needle scaling) or chemical rust converters depending on location and constraints.
- Achieve minimum surface preparation standard (e.g., AS 1627.4 Class 2.5) for coating adhesion.
- Structural Repair
- Where section loss exceeds design tolerances, fabricate and weld/bolt steel plates or replace sections.
- Reinstate protective wrapping or encasement for embedded steel.
- Protective Coatings
- Apply multi-layer protection:
- Zinc-rich primers for cathodic protection.
- Epoxy build coats for chemical resistance.
- Polyurethane or polysiloxane topcoats for UV stability.
- Use colour-matched finishes for exposed elements in architectural applications.
- Apply multi-layer protection:
- Preventive Measures
- Seal joints and penetrations to block water ingress.
- Apply sacrificial anodes or impressed current cathodic protection for high-risk environments.
Applications
- Concrete Structures: Treating rebar corrosion in spalled slabs, beams, and columns.
- Exposed Steelwork: Façade brackets, balustrades, structural beams.
- Marine & Coastal Buildings: High-chloride environments where accelerated corrosion is common.
- Heritage Structures: Retaining original steel components with minimal intervention.
Why Atomic Projects for Steel Corrosion Treatment
- Engineering Precision: All treatments designed to restore original load capacity.
- Advanced Protection: Use of marine-grade and high-performance coating systems.
- Integrated Remediation: Treatment linked to root-cause repairs, stopping corrosion at its source.
Corrosion treatment is not just about removing rust — it’s about extending the life of the structure and safeguarding it against the environment for decades to come. When executed to a Tier 1 standard, it protects both the asset’s value and its safety.
