Which is better TMT 500 or 550d?

What is the Difference between TMT Fe 500 and 550 Grade? – Which Brand Tmt Bar Is Good For Construction With the rising need for high rise construction and critical infrastructure projects, it is very important to use very strong and stable steel bars – which can help construction structures withstand the effects of time, seismic activities, changes in temperature, natural hazards and more.

  1. Fe 500 and Fe550 grade bars are being used increasingly for the construction of various types of projects today.
  2. Read and find out about some of the major differences between the two grades of TMT bars.
  3. Strength The numbers, after the name of the brand, actually represents the grade of the respective TMT Steel rod, orin other words, the strength of the steel.

When Steel TMT bars have a higher grade, they are much stronger in nature. The numeral actually measures the minimum stress and in N/mm2. Properties The two types of Steel bar grades are different in terms of chemical and physical properties slightly. Although the YTS ratio is the same in case of both, there is a difference in the elongation percentage – which means the higher the elongation percentage, the better the capacity of the TMT Steel rod to perform in extreme situations.

The elongation percentage of Fe 500 grade is higher than the Fe550 grade TMT bar, Weld-ability With a lowering of carbon content the weld-ability of steel bars can be improved, whereas reduced impurity of sulfur and phosphorus can make TMT steel bars more ductile and tough. It is no wonder then that both grades are being used in a widespread manner, and are a top choice for contractors today.

So Which One is Better? Fe 500 is good – due to its higher seismic ability and ductility. It is possible to use Fe 500 across a wide range of multi-storey commercial and residential projects. These come with high level of ductility and strength and are manufactured especially to give stability to high rise constructions.

  • These can resist load much better, and are useful in all those areas with sudden loads or high seismic activities.
  • The tensile strength of Fe 550 grade bars is higher so these can be used across a wide variety of large scale projects.
  • These are better than Fe 500 words in terms of strength and are used for the development of large infrastructural and industrial projects, such as bridges and structures that need to bear a higher amount of load.

These kinds of bars are particularly useful in underground, marine and coastal ambiences.

Why Tata Steel is costly?

Operating expenses per tonne – Operating expenses per tonne is the company’s total operating cost to produce one tonne of steel. Lower the number, the better. The cost per tonne for Tata Steel has grown at a CAGR of 8.5% against a 17% of JSW Steel in the last five years.

In 2021-22, JSW Steel had to incur higher cost per tonne on account of higher raw material prices the company imports (coking coal). Tata Steel did not bear this brunt as the company sources most of the required raw materials from its captive mines in India. However, barring this year, Tata Steel’s cost per tonne has been higher than JSW Steel’s, indicating that the company has a cost advantage over Tata Steel.

A primary reason for higher costs in Tata Steel are the European, UK and the Middle Eastern markets it operates in. These markets have a higher costs of production compared to the Indian market. Therefore, the company’s consolidated business reports a higher cost per tonne compared to JSW Steel.

Which steel is best for roof slab?

Basics of Building Construction The design of a roof slab consists of thickness of slab, size of bars, spacing of bars, hooks, cranks and laps of bars, minimum cover of concrete etc. The mix of concrete for the slab is usually by volume and is of proportion 1:2:4 (, sand and aggregate) Due to the loading conditions the slab is subjected to possible or sagging bonding movement on the bottom surface at the centre of the span and negative or hogging bending moment at top near supports.

  • To resist these moments main reinforcement is provided at bottom surface along the direction of span to resist positive bending moment.
  • Depending upon the span, an RCC slab may be designed as either one way reinforced slab or two way reinforced slab.
  • The slab which is supported on two opposite supports is called as one way slab.

This slab is considered to be supported on two longer opposite sides. When the ratio between the length and breadth of the room over which the slab is provided is more than 2. One way slab consists of main reinforcement spanning between the supports with distribution of reinforcement at right angles to it.

  • Two way slab is said to be spanning in two directions, when the length to breadth ratio falls below 2.
  • In such case, main reinforcement is provided in both directions in the form of a mesh.
  • The overall thickness of slab is usually kept 10 cm though the minimum thickness can be 7.5 cm.
  • The minimum area of reinforcement per unit width of a slab shall not be less than 0.15%.

of the gross cross sectional area of concrete. But due to other limitations, it becomes necessary to provide higher percentage of steel in the slab. Spacing of bars of main reinforcement shall not be more than 3 times the effective depth of slab and that for the distribution bars not more than five times the effective depth.

Spacing of not more than 20 cm diameter for main bars and not more than 40 cm for distribution bars is usually provided. Bars smaller than 6 mm diameter or greater than 18 mm are not used for slabs.10 mm or 12 mm plain M.S. bars or 8 mm or 10 mm tor-steel bars are generally used. They are provided at the bottom of the slab allowing minimum cover of 25 mm of concrete.

In addition to bars along the main direction, provided at the bottom, bars along the longer span are also placed on top of the main bars and at right angles to them. These are called ‘ distribution’ bars or ‘temperature reinforcement’ or ‘ transverse bars’.

The distribution bars function to resist cracks due to variation of temperature and shrinkage stresses. They also assist in distribution of loads. The area of such reinforcement is usually 20 % of that of main reinforcement. Plain M.S. bars of 6 mm diameter are usually used for this purpose. In all buildings, slabs covers the full width of the wall over which walls are raised.

This creates partially fixed conditions for the slab. In such cases, every alternate bar is bent up. This arrangement is economical as compared to providing additional bars at the top. The main bottom bar is cranked at one-fifth of the span at either end and taken up.

  1. Main and distribution bars are tied together with black mild steel wire of 16 guage by providing a cross and twisting the ends.
  2. If smaller diameter of wire is used, double strands of wire shall be provided in place of single strand.
  3. About 5 kg.
  4. Of binding wire is required for tying 1 tonne of reinforcing bars.

Considering a 2.5 M or 8’0″ wide verandah by way of example, the thickness of slab is 10 cm. Main bars are 10 mm plain M.S. or 8 mm tor-steel and are placed at 20 cm centre at bottom of the slab along the short span allowing a cover of 25 mm. Every alternate bar is cranked up to 0.5 M from the edge of wall and at both ends 6 mm plain M.S.

bars are used as distribution bars and are placed at 30 cm centres at the top of the bottom bars. For the cranked bars near the supports at the top of the slab distribution bars of same size and same spacing are provided below the top bars. Two-Way Slab In providing steel for a two-way slab, the bars in both directions shall be of the same diameter and of the same kind i.e.

either plian or tor-steel. The bottommost layer will be along the shorter span. Same size bars along the longer span shall be placed on top of these bars and at right angles to them. No extra distribution bars are necessary. Cranking of alternate bars shall be done at 1/5th span from support on all the four sides and cranked bars taken to the top which come at the top of slabs over the supports allowing usual cover.

  1. If the slab of one room continues over the adjacent room the portion of the slab over the common intermediate support needs top reinforcement.
  2. The bars in the middle portions in short span direction will be at the bottom whereas those over the intermediate supports will be at the top.
  3. The spacing of a given size of bar in all these positions depends upon the lengths of spans and upon the loading conditions and is determined by,

It is desirable for sake of convenience of workmen and the supervisor to adopt the same spacing for the bottom bars at the midsection of the slab as that of the top bars over intermediate supports. Every alternate bottom bar when cranked up at 1/5th of the span serves as the top bar over supports which should be extended upto a distance equivalent to 1/4th of the adjacent span.

Which steel bar is used for slab?

Mild Steel Bars – This bar does not have any ribs; it comes with plain surface and in round shape. Mild Steel Bars are used in RCC for beam, slabs etc. The Tensile Strength is upto 40000 psi. Mild Steel Bars does not bond well with concrete and it is poor in quality that is why it is used in small projects with budget constraint.
