Warnings and safeguards in rod use; 

There are various rods available in the market, starting from 5 millimeters to 4, 5, 6, 9, 25 and 25 millimeters. However, there are usually three types of rods used in building construction. Each type of rod is used for piling, slab, beam or column making. If the rod can form a good bond with the concrete, the rod is good. The rods are available in the market upto grade 5, grade 8 and grade 12. The grade 5 rod is rarely used. Usually the grade 5 rod is more used in building construction.
Warnings and safeguards in rod use.

In case of rod purchase

>> The size of the iron rod should be equal in size.

>> No cracks or sores.

>> Bond is better at deferred bar than plain rod.

>> Rusty infected rod does not have to be used without removing the 

Technical Issue

>> The rod should be mounted at the designated point with the help of GI-wire and cover block.

>> Adequate development length should be given during Rodlaga

(3d, where d = the diameter or diameter of the rod)

>> Where there are pairs of two rods, the minimum lapping should be given

 Alert on reservation

>> It's best to never put the rod directly on the ground.

Make a bed with wood, bamboo or anything else underneath the rod.

>> Do not place the rod in such a place, soaked in rain. Because, during the rain, the clay sprinkles on the rod, which causes rust in the rod.

In addition, the ridge on the rod can also be rinsed.

>> Do not fasten the rod for welding purposes. It weakens the wire binding cables. As a result, the opening of the embankment in various places will cause disruption to the work.

Roof open column rod

After casting the roof, it is necessary to place the rod in the column for the roofing again. If the next roof construction requires a prolonged break, the open rod of the column on the roof can be damaged. For this, the following measures can be taken:

1. Red oxide coating may be provided

2. Nickel and chromium with iron prevent the rust of the metal

3. Grizz can be used.

4. If long breaks are required, the extra part of the column should be welded with weak concrete. On one side, the rod is protected from rust.

It is also advantageous to break down that weakened concrete and then break it down due to the weak concrete.

There is no damage to the required columns under the roof.

So it's best to keep welding.
