Lap length is the length overlap of bars tied to extend the reinforcement length.. Lap length about 50 times the diameter of the bar is considered safe. Laps of neighboring bar lengths should be staggered and should not be provided at one level/line. At one cross section, a maximum of 50% bars should be lapped.
In case, required lap length is not available at junction because of space and other constraints, bars can be joined with couplers or welded (with correct choice of method of welding).

What is lap Length of steel Bars?
Over lap of steel bar is provided 60 times of dia of steel bar. For example (.5") dia steel bar overlap length is (30"). (.5x60=30")
What is the hysd steel bars?
High yeild strength deformed bars. The characteristic strength of these bars are higher than mild steel.
What does deformed steel bar mean?
Deformed steel bar is more commonly known as reinforcing bar, or rebar. These steel bars are imbedded in concrete to provide tensile strength. Smooth bars are run through rollers which "deform" the bar thereby adding ribs. The ribs provide a mechanical bond between the steel bars and the surrounding concrete.
Can you pour concrete to steel bars painted with red oxide primer?
No, it is not recommended to pour concrete directly onto steel bars painted with red oxide primer. The primer may prevent proper adhesion between the concrete and the steel, leading to a weaker bond and potential structural issues. It is important to remove any paint or primer from the steel bars before pouring concrete to ensure a strong and durable connection between the two materials.
Why staggered lap is necessary in steel bars?
we need the same steel area for the structure

How much length of steel in a ton?
The length of steel in a ton can vary significantly depending on the shape and size of the steel. For example, a ton of standard structural steel beams could be around 66-70 feet in length, whereas a ton of rebar (reinforcing steel bars) could be around 150-200 feet in length. It is important to consider the specific dimensions and type of steel when determining length per ton.

What is anchorage length?
This is the additional length of steel of one structure required to be inserted in other at the junction. For example, main bars of beam in column at beam column junction, column bars in footing etc. The length requirement is similar to the lap length mentioned in previous question or as per the design instructions.
