Rolling shutters are among the most common types of doors where the large size of openings, safety, protection against fire, and theft are a concern. The rolling shutter is made from heavy steel strips interlocked and hinged for maximum strength. These shutters are fixed with coiled springs for smooth operation. Rolling shutters give complete protection and high resistance power against wind, rain, and burglary.
The rolling shutter doors are classified based on materials, operations of the shutter, application.

How to calculate the surface area of the rebar?
Fasi Ur Rahman
Calculation of the surface area of the rebar- Considering the dia of rebar as 16mm and length as 1m. Surface area= Length x Circumference of the bar (Considering bar having smooth surface) = 1 x 2 π r = 1 x (2 x 3.142 x 0.008) =0.05 Sqm

The first and foremost reason is leakages which are caused due to joints in the roof. If it is a sloping roof, then chances are there at the joints and junctions.
One of the reasons why roof tiles break is simple wear and tear. In addition to wear and tear, harsh weather conditions may cause tiles to fall apart. If it is a flat roof, the chances of leakages are due to poor workmanship or cold joints in the concrete.
The roof leakage can be fixed by following repair methods-
The cost of repairing a flat roof is generally affordable but really depends upon the extent of the damage, the location of the project, and the availability of repairing agencies.
To read in detail about the repair procedure and cost incurred for fixing roof leakage, read the article-

Dear Arun,
The typical joining details at the junction of Column and beam is as shown as in the attached figure.
The beam main bars shall be cranked near the columns and the crank length shall be 1: 4.
In any case, the beam rebars shall not be passed from the outer of the column rebars which will compromise with the covers of the concrete.
