The longer you can maintain your structure without needing replacements, the lesser the environmental impact from manufacturing and fabrication. Steel is renowned for its exceptional strength and durability, capable of withstanding over 100kg of force per square millimeter, making it more than three times stronger than aluminum. Consequently, steel railings and structures are likely to outlast their aluminum counterparts, reducing the need for frequent replacements and thus minimizing environmental impact.

While both steel and aluminum are recyclable, steel has an edge due to its simpler recycling process. Aluminum can contain various alloying elements, complicating its recycling, especially when transitioning between different uses. In contrast, steel can be recycled effortlessly for a myriad of applications without loss of quality, making it a more sustainable and environmentally friendly option.

The production of steel is also advantageous from an environmental standpoint. Up to 70% of steel can come from recycled materials, reducing the need for new raw materials and minimizing landfill waste. Moreover, modern steel production techniques have significantly cut down on energy consumption, lowering the carbon footprint. Steel does not involve toxic materials or coatings, ensuring that it doesn't contribute to harmful environmental runoff.
