Corrugated steel rebar (https://aksvil.by/armatura/) is a type of reinforcement used in construction. It is made by cold-rolling steel bars to create a pattern of ridges and grooves along its surface, which gives it a corrugated appearance.
The corrugated pattern on the surface of the steel rebar provides several benefits over traditional smooth steel bars. First, it increases the surface area of the steel, which improves its bond strength with concrete. This means that concrete adheres more tightly to the surface of the steel, creating a stronger bond that can better resist forces like tension, compression, and bending.
Corrugated steel rebar also provides better shear transfer between the steel and concrete, which improves the overall structural integrity of the reinforced concrete. Additionally, the corrugated pattern helps to prevent slippage between the steel and concrete during earthquakes or other seismic events.
In summary, corrugated steel rebar is a specialized type of reinforcement used in construction to improve the strength and durability of concrete structures. It is particularly effective at resisting forces like tension, compression, and bending, and is often used in high-stress applications like bridges, highways, and other large-scale infrastructure projects.
