Steel balustrades are a critical safety feature for walkways, stairways, and balconies. They provide a protective barrier against falls and other accidents, ensuring the safety of everyone who uses these structures. However, it is essential to keep steel balustrades properly maintained, particularly where they are connected to concrete balcony slabs.
Balustrades are regulated by Australian Standards (AS) and the Building Code of Australia (BCA). AS 1170.1 outlines the loadings and stresses that balustrades must withstand, while AS 1926.1 specifies the minimum height and spacing requirements for balustrades. Compliance with these standards is crucial to ensure the effectiveness of balustrades in preventing falls.
Maintaining and repair of steel balustrades is crucial for several reasons, including safety, corrosion prevention, and aesthetic appeal. A well-maintained balustrade can improve the overall appearance of a building, particularly for commercial properties where appearance can impact business success.
However, if rusting occurs at the connection to the concrete floor slab, it can lead to the development of concrete cancer. Concrete cancer is the term used to describe the deterioration of concrete caused by rusting steel reinforcement bars (rebars) within it. The rusting process causes the rebars to expand, leading to cracking and spalling of the concrete. If left untreated, concrete cancer can cause significant structural damage, posing a safety risk to occupants and visitors.
To repair steel balustrades and prevent the development of concrete cancer, it is crucial to address the root cause of the issue. This may involve removing the damaged concrete and replacing it with new concrete or applying a protective coating to the affected area.
Regular inspections and maintenance can prevent corrosion and identify any issues with the balustrade. If rusting occurs at the connection to the concrete slab, prompt repairs should be undertaken to prevent the development of concrete cancer. Concrete cancer is a term used to describe the deterioration of the concrete caused by rusting steel reinforcement bars (rebars) within it.

If left untreated, concrete cancer can cause significant structural damage, posing a safety risk to occupants and visitors. By keeping steel balustrades properly maintained, we can ensure the safety of everyone who uses them and prevent costly repairs in the future.
In conclusion, steel balustrades on walkways, stairways, and balconies require regular maintenance to ensure their safety and effectiveness. Compliance with Australian Standards is essential, and prompt repairs by professionals are necessary if rusting occurs at the connection to the concrete slab to prevent the development of concrete cancer. By keeping these safety features well-maintained, we can ensure the longevity of the structure and the safety of those who use them.
