Our birds are designed with 3mm CorTen steel to form a protective patina that deepens and strengthens with the seasons. This patina will deepen in shade over the years until it reaches a deep brown/charcoal black hue.

This self-sealing aspect of CorTen steel provides a quality guarantee of up to 100 years, ensuring that our product lasts a lifetime and remains completely corrosion resistent.

What might initially resemble generic rust is simply the air and water-tight patina forming over a six month period, so don’t panic! Your Metalbird is doing exactly what it’s been designed to do, and this patina will protect the steel from any further damage and disintegration.

CorTen steel does not require any treatments, oils or chemical additives and is therefore extremely environmentally friendly.
