Balustrade Materials and the Environment, Aluminium or Steel

When it comes to designing and constructing building projects, it’s essential to consider the environmental impact of the materials being used. One such decision is the choice between aluminium and steel balustrades. Balustrades are functional and aesthetically pleasing safety features that can be found in various applications, such as staircases, balconies, and decks. In this blog section, we will delve into the environmental impact of aluminium and steel balustrades and explore which material is better for environmentally conscious projects.

Aluminium Balustrades

Aluminium is a lightweight, corrosion-resistant metal that has seen an increase in popularity in recent years due to its environmental benefits. One of the main advantages of aluminium is its recyclability. Aluminium can be easily and infinitely recycled without losing any of its properties, making it a sustainable choice for balustrades.

The production of aluminium is also less energy-intensive than steel, as it requires less heat during the extraction and refining process. This results in a smaller carbon footprint and fewer greenhouse gas emissions. Additionally, aluminium is abundant in the Earth’s crust, making it a more readily available resource compared to other metals.

However, it’s important to note that the initial extraction of aluminium from bauxite ore is an energy-intensive process that generates significant greenhouse gas emissions. Therefore, it’s essential to ensure that the aluminium used in balustrades is sourced from recycled materials or responsible mining practices.

Steel Balustrades

Steel is a strong and durable material that has been popular for balustrades for years. Its high tensile strength makes it ideal for supporting weight and providing structural stability. However, steel production has a higher environmental impact than aluminium.

The production of steel is an energy-intensive process that generates a significant amount of greenhouse gas emissions. Additionally, steel production is associated with air and water pollution due to the release of various harmful substances, such as sulfur dioxide, nitrogen oxides, and particulate matter.

While steel is recyclable, the recycling process still requires considerable energy, and not all steel products are made from recycled materials. Furthermore, steel is susceptible to corrosion, which can result in the need for maintenance or replacement over time, contributing to more waste and energy consumption.

Comparing the Environmental Impact

When comparing the environmental impact of aluminium and steel balustrades, it’s essential to consider the entire lifecycle of the product, from production to disposal. Aluminium balustrades have a smaller carbon footprint due to their lower energy requirements during production and their recyclability. On the other hand, steel balustrades have a higher environmental impact in terms of energy consumption, greenhouse gas emissions, and pollution throughout their lifecycle.

It’s also important to consider the longevity of the balustrade material. Aluminium’s corrosion resistance and recyclability make it a more sustainable choice in the long run. While durable and strong, steel may require more maintenance, replacement, and energy consumption over time due to corrosion.


When considering the environmental impact of balustrade materials, aluminium emerges as the more sustainable choice. Architects, builders, and homeowners who are looking to minimise their environmental footprint should opt for aluminium balustrades, especially those made from recycled materials or responsibly sourced aluminium. While steel remains popular for its strength and durability, its environmental impact throughout its lifecycle cannot be ignored. We can contribute to a greener and more environmentally responsible future by choosing sustainable materials like aluminium.
