What Is the Best Metal for Bespoke Stairs?

Choosing the right metal is crucial for style and longevity. We are experts in various steel types:

Mild Steel: Our most versatile and strong choice, great for both internal and external usage. A powder-coating finish adds essential resilience to weather and wear.
Stainless Steel: Ideal for sleek, modern looks and naturally resistant to corrosion. Perfect for high-humidity areas or properties near the coast.
Wrought Iron: Best suited for ornate designs with traditional aesthetics, including curves, scrollwork, and intricate balustrades.

Each metal offers different strengths, and we are here to guide you toward the best material for your specific project and lifestyle.

How Long Does a Handcrafted Steel Staircase Last?

With the correct finishing and professional care, a handcrafted steel staircase can last 50 years or more, making it a superior long-term investment.

External staircases benefit hugely from weather-resistant coatings (e.g., galvanising).
Indoor models retain their strength and elegance with minimal maintenance.

Steel is a standout choice compared to materials like wood, which is often prone to warping, moisture damage, or insect treatment requirements over time.
