Selecting metal resources
The environmental impacts depend on the steel grade used in concrete. Most often the steel in concrete is reinforcement steel. Stainless steel is usually used only if there is high exposure (for instance by weather) and high-tensile steel is used for pre-stressed concrete elements.
From an environmental impact point of view, there are three major types of concrete reinforcement steel:
- Reinforcement steel that typically contains a lot of recycled steel and has thus low environmental impacts
- High-tensile steel that usually contains virgin steel
- Stainless steel
For other use of steel, you must choose the right kind of steel. The basic options are:
Hot-dip galvanized steel
Hot rolled steel
Usually, structural steel is one of the basic options. Make sure you have the right type and correct amount of steel and the environmental impact will be in a reasonable scale.
For aluminum, the most important factor defining the environmental impact is to choose the right kind of treatment.
Typical treatments are:
- polyester powder-coated
Apart from treatment, the environmental impacts vary depending on the aluminum’s recycled content and manufacturing country (defines which energy profile has been used).

Selecting concrete resources
The major factor defining the environmental impacts of concrete is the amount of cement in the product which depends on the concrete strength class (e.g. C25/30 in Europe). If you cannot find the exact product you are using, choose one that has the ...
