teräsvahvistusverkot
Teräsvahvistusverkot, often referred to as steel reinforcing mesh or rebar mesh, are prefabricated steel grids used to reinforce concrete structures. They are typically manufactured by welding or electrically bonding steel bars at regular intervals, forming a square or rectangular mesh pattern. The primary purpose of these grids is to enhance the tensile strength of concrete, which is inherently weak in tension but strong in compression. By embedding teräsvahvistusverkot within the concrete, the structure becomes more resistant to cracking and deformation caused by tensile forces.
The manufacturing process involves using high-quality steel bars, often ribbed to improve adhesion with the concrete.
The use of teräsvahvistusverkot offers several advantages. They contribute to faster construction times compared to manually
