Metal

Steel
The VELFAC 200-series consists of 1.8 percent steel. The material is used in the hinges of our windows for holding the frames in place.

Steel is made of iron, which is one of the most commonly available materials in the earth's surface. It is stronger, more durable and easier to process than iron, making it suitable for use in the construction industry. Steel used as a building material generally has a longer life cycle compared to other types of application. 

Excellent recycling perspectives
Steel is the most commonly recycled material in the world and it can be reused again and again without any loss of quality. At the same time, steel has a number of properties that make it suitable for recycling. Especially its magnetic property, which contributes to streamlining the sorting process in connection with recycling. At the same time, it takes far less energy to recycle steel after use than any other metals. Steel is recycled by downgrading it to sheet iron and similar materials.     

Steel may even be recycled by converting it into new steel. The material can also be reused as new components such as metal sheets, steel chips, etc. Furthermore, steel components can be reprocessed and adapted to be used, for example, as new building materials

Zinc
The VELFAC 200-series consists of 0.5 percent zinc. The material is used in the hinges of our windows for holding the frames in place.

A sustainable building material
Zinc is a naturally occurring metal. It is extracted from ores found in abundant quantities in the earth's crust. The manufacturing process requires only a limited amount of energy, and zinc is one of the most abundant metals in the world.

It requires no maintenance and it has a long life. On top of that, zinc emits the lowest amount of CO2 compared to other building materials. It is also a commonly reused material. One of the main reasons for this is that zinc can be recycled up to 100 percent without any loss of its properties.

Zinc is so easy to recycle that 96 percent of it is currently being recycled. Zinc is recycled by melting it, and there are huge environmental benefits to be gained in connection with recycling. Energy consumption for recycling is reduced by up to 95 percent in the process.
