Metallförstärkningar

Metallförstärkningar, often referred to as rebar in English, are steel bars used to reinforce concrete. Concrete is strong in compression but weak in tension. When concrete is subjected to bending or tensile forces, it tends to crack. Metallförstärkningar are embedded within the concrete to provide tensile strength, thereby increasing the overall structural integrity and load-bearing capacity of the composite material.

These reinforcing bars come in various diameters and surface textures. The ribbed or deformed surface of metallförstärkningar provides better mechanical anchorage to the surrounding concrete, preventing slippage and ensuring that the steel and concrete work together effectively. They are essential components in a wide range of construction projects, including buildings, bridges, dams, and roads. The placement and quantity of metallförstärkningar are determined by structural engineers based on the anticipated loads and stresses the structure will endure. Corrosion of metallförstärkningar can lead to concrete degradation, so proper concrete cover and, in some environments, protective coatings are crucial for long-term durability.
