Production Features

Strong mechanical bite force

The ribbed design on reinforcing deformed steel bar surface makes the anchoring performance of the steel bar in the concrete significantly improved, which can more effectively resist the tension and shear force, and enhance the stability of the overall structure.

High strength

After hot rolling or cold processing, it has high yield strength and tensile strength, which can meet the needs of different projects for material strength.

Convenient construction

Compared with ordinary round steel, this kind of steel bar is more convenient in bundling and welding, improving the construction efficiency and reducing the quality hidden dangers caused by the slip of steel bars.

Good corrosion resistance

Some round deformed bars are galvanized or coated with anticorrosive materials during the production process to improve their durability in wet or corrosive environments.

Mechanical Property

Reinforced steel deformed bars have relatively high yield strength and tensile strength. Compared with ordinary steel bars, it has undergone special processing techniques, and its surface forms uneven ribbed or spiral structures. This structure not only increases the bonding force between the steel bars and concrete but also enables the steel bars to better disperse stress when subjected to force. In addition, under the condition of long-term exposure to periodic loads, deformed bars can still maintain stable mechanical properties and are less prone to fatigue failure.
