Raudoitusverkot

Raudoitusverkot, often translated as reinforcing mesh or rebar mesh, are steel wire grids used to strengthen concrete structures. They are typically made of interconnected steel bars or wires arranged in a rectangular or square pattern. The primary purpose of raudoitusverkot is to enhance the tensile strength of concrete, which is inherently weak in tension. By embedding these meshes within the concrete, the overall structural integrity and load-bearing capacity are significantly improved.

The manufacturing process involves welding or weaving steel wires or bars together to form the mesh. The diameter of the wires or bars, as well as the spacing between them, varies depending on the specific application and the required strength. Common applications include reinforcing concrete slabs for floors, walls, foundations, and roads. They are also used in precast concrete elements and in repair work for existing concrete structures.

The use of raudoitusverkot helps to prevent cracking in concrete due to shrinkage, thermal expansion, and applied loads. The steel mesh effectively distributes stress throughout the concrete, reducing the likelihood of localized failure. Proper installation is crucial for their effectiveness, ensuring that the mesh is positioned correctly within the concrete pour and is adequately covered by concrete. This material is a fundamental component in modern construction, contributing to the durability and safety of countless buildings and infrastructure projects.
