Reinforcing Bar is also known as rebar,Y-bar deformed bar.

Deformed reinforcing bar and smooth bar as building materials are widely used for reinforcing concrete structures in construction, chemical and petroleum industries.

Deformed bar is used where extra reinforcing is required to fabric sheets or trench mesh. By use the reinforcing bar in construction, It creates a single, monolithic concrete structure with high durability, reliability and integrity. Meanwhile, reinforcement bars increase stability and resistance to mechanical stress.
Benefit: high strength, fire resistance, durability.

Note:

• Reinforcement steel bar in other diameter is available upon special order.
• We also have the capacity to cut and bend our reinforcement to address the specific requirements of your project.
• Swimming pool reinforcing bar from mild steel bars very easy to bend by hand, used in the construction of domestic swimming pools, also offered in our company with 6m or 9m length.

Reinforcing bar lap
Reinforcing bar laps need to be overlapped by at least 500mm. As Figure 1.
