Rolling Margin is the deviation of actual unit weight to that of Standard unit weight as per IS Standards.
Rolling Margin is calculated as :
Sectional weight = Weight of Steel Bars dia wise / length of the bars.
As per IS Standards unit weight of the Bars is calculated as dia x dia / 162
Rolling Margin is deviation of actual sectional weight to that of IS Standard unit weight.
Standard Rolling Margin for different dia reinforcement bars used for construction purposes:
8mm to 10mm +- 7%
12mm to 16mm +- 5%
20mm & Above +- 3%

The bond of a brick wall refers to?
In block wall construction (CMU) "bond beam" refers to a course (horz row) that is filled with grout and steel reinforcement. I have not heard the term used in residential construction.
What is the term dead man referring to when used in construction Is it like some form of weight or anchor?
It is a dead weight (concrete or steel) landed on the seabed which is used to initiate a pipeline or umbilical. It is named "Dead Man" because it doesn't move!
What does tgi stand for in construction?
In construction, TGI stands for "Truss Girder I-beam." It refers to a type of engineered wood or steel beam that is designed in the shape of an "I" to provide strength and support for structural applications. TGI beams are commonly used in floor and roof framing due to their efficiency in load distribution and lightweight properties.
What two types of steels are used for structural steel?

Why steel is used to reinforce concrete?
Concrete reinforcing steel is commonly used in bridges, buildings, skyscrapers and road construction. Reinforcing concrete with steel significantly increases its strength in an economical and safe manner.
Can you explain the concept of a rolling wall and how it is used in construction projects?
A rolling wall is a temporary structure used in construction projects to create a barrier or enclosure that can be moved along a track. It is typically made of materials like steel or aluminum and can be adjusted to different heights and lengths. Rolling walls are used to separate different areas of a construction site, control access, or provide protection from hazards. They are versatile and can be easily repositioned as needed during the construction process.
What is is 2062 is it hot rolled or cold rolled?
2062 is a type of structural steel alloy primarily used in construction and manufacturing. It is typically available in hot rolled form, which involves rolling the steel at high temperatures to shape it. Hot rolling enhances its toughness and ductility, making it suitable for various applications. Cold rolling, on the other hand, is not commonly associated with 2062.
What is CRS substrate?
CRS substrate, or Cold Rolled Steel substrate, is a type of material used in the production of various steel products. It is formed by rolling steel at room temperature to give it a smooth finish and desired dimensions. CRS substrate is commonly used in industries such as automotive, construction, and appliances.
What are 2 objects made from steel?
Steel beams used in construction. Steel kitchen knives.
Is light gauge steel framing cold formed?
Yes, light gauge steel framing is cold-formed. This construction method involves shaping steel sheets into structural components using a cold-rolling process without the application of heat. The resulting lightweight and durable steel sections are commonly used in building construction for walls, floors, and roofs. Cold-formed steel framing offers advantages such as precision, strength, and resistance to pests and rot.
How much steel is used today in construction?

Is rolling margin is payable to contractors?
Rolling margins are typically not directly payable to contractors; instead, they refer to a financial concept used in project management and pricing strategies. A rolling margin represents the profit margin that adjusts based on the project's ongoing costs and revenues. This can influence how contractors price their work but does not constitute a direct payment or margin paid to them. Instead, contractors are generally compensated based on the agreed-upon contract terms, which may include fixed or variable pricing.
Why was steel able to be used in bridge construction?
After 1856 the invention of the Bessemer process for producing steel by reducing the carbon content of iron made possible the incorporation of steel into bridge construction.
