Steel reinforcement for house construction

Steel reinforcement for house construction

Steel reinforcement

In civil engineering, it is mostly referred as reinforcements or rebar and as discussed in earlier blogs about cement sand and bricks, it is another crucial material required during grey structure construction of house. Steel is used in form of meshes to strengthen and hold concrete together. Without reinforcements, concrete cannot sustain heavy tension since it has weak tensile strength. Rebar is usually manufactured in two grades for domestic utilisation in Pakistan where the grade indicates its minimum yield strength:

-Grade 40

-Grade 60

Rebar used in construction of houses is further classified as:


-Tor bar

Deformed bars are mostly used in all type of reinforcements such as in lintels, slabs etc. in domestic residential constructions in following sizes:

Some of the most reputable brands of steel used in Pakistan are:

  1. Ittefaq
  2. Ittehad
  3. Model
  4. Saeed kasur
  5. Mughal
  6. Amreli
  7. Izhar
  8. Pak steel

Always use branded steel during construction of your house. There are many other local mills that produce rebar and are available at cheaper rates. It will be wise to stay away as there should be made no structural compromise at any stage of construction.

Quantity check on site

Steel is purchased and offloaded on sites in bulks of tons, hence it becomes difficult and a little complicated to perform quantity check on site. Purchase from reputable dealers and avoid street wandering agents just like the case in cement. It has daily-based rates which vary. Many fraudulent dealers will offer a lower price as compare to market rate, which they later recover during weighing process and a layman will not be able to notice the damage. Stay alert during weighing process even if you are buying from reputable dealer and when the steel is being transported from store to your site. However if you still want to verify the amount of steel offloaded on site, you can calculate by counting total lengths and multiply below mentioned kg/ft. figures with total running feet of steel of respective bar designation.

Quality check on site

Most of the quality checks on steel such as yield strength test, tensile strength test etc. are carried out in labs with proper instruments. However on site you can carry out following basic checks for satisfactions:

Weight test

Weight of the bar per length or per running foot should be the same as mentioned in above table.


It should not be hard and un-bendable. It should be easily bent to 90° and straighten back without breaking or any signs of cracks.

    You have missed to discuss two big names of Steel Industry, 1) Faizan Steel and 2) SAJ Steel. I Havve Visited both of them Personally. And i have to say they are producing the best standard of G60 Deformed Bar in Karachi.. and Faizan Steel’s C-Bar is tremendous.

  • Shan on February 25, 2021

    I have used Faizan Steel & SAJ Steel in Karachi and i have to say both are much better then Well Known Big Brands like Amreli and Mughal.. Faizan Steel is One of the Best Steel Manufacturer from Karachi. And I have personally used Faizan Steel and SAJ Steel in My Home Construction.. They are far better then Amreli, Mughal and Agha.

    I am building 1 Kanal house, which steel thickness is good. As per my design 3/8 (3 sotar), 1/2 (4 sotar) and 1/2 (6 sotar) is mentioned but mostly 3/8 is used. some says use 1/2 instead of 3/8, please guide in this regard..

    • Mohsin Munir on September 27, 2020

      Just follow the structural drawing. Drawings are made by structural engineer. Ones who are saying this is better than that most probably wont be structural engineers

    • Jawwad Farooq on November 19, 2020

      So did you use 3/8 or 1/2?

      • Mohsin Munir on November 19, 2020

        Wahtever structural engineer has recommended that should be used.

  • toqir on April 17, 2020

    give your rate plz

    • Mohsin Munir on April 17, 2020

      We do not give approximate rates. For approximate/prevailing market rates you can go to “latest market construction rates” blog in all blogs section.

      We give rates only after studying detailed working drawings.

  • toqir on April 17, 2020

    kindly give your rate for grey structure in lahore for 1 -kanal house after GOP announced construction amenity scheme and withdraw / reduce taxes.

  • toqir on April 17, 2020

    kindly as of today on 17 april 2020 after construction package by GOP what is grey structure rate in lahore of your company of 1 kanal house

    • Mohsin Munir on April 17, 2020

      No change in rates yet. It takes months for effect to tickle down. We will be uploading detailed video on the ordinance tomorrow on our youtube channel stay tuned

    AOA Mohsin Bhai . i am planning to construct 1 kanal House in Lahore kindly guide which brand of 60 GRADE steel bar is best in lahore like model , mughal supreme ,efco etc

    • Mohsin Munir on April 17, 2020

      Mughal supereme, Model, Saeed Kasur, Efco all are very good steel brands you can use any of them.

  • Abdul Ahad on January 22, 2020

    Assalamoalikum Mohsin bhai. Kindly suggest me which steel brand and which grade should we use in 5marla double story. Im from karachi.

    • Mohsin Munir on January 22, 2020

      I have never worked in Karachi. I guess amreeli steel is most famous brand there.

  • Shahzaib Nazim on November 13, 2019

    AOA, I purchased Faizan steel bars and dealer told me that it is grade 60 and it is 5 to 6k cheaper than amreli, but grade is not embossed on the bars, how can I get to know either it is 60 or 40 without test?

    • Mohsin Munir on November 13, 2019

      Only method to check the grade is now to get it tested from labs.

  • Adeel on October 7, 2019

    Hi mosin bhi I want to know that how much steel used on 100 guz roof and cement accurate a standard material plz reply

    • Mohsin Munir on October 7, 2019

      Brother, there is no such set standard/criteria for steel and cement according to which i can tell you accurately how much steel or cement will be used in 100 guz (btw I have no idea what do you mean by 100 guz). These calculations are done from working and structural drawings.

    I have recently received initial soil test report for my 10 marla plot in bahria enclave islamabad. In report 16 feet filling has been mentioned and cut is written on 16 feet 2 bore holes. their technician told me that u have to do piles for 7 -10 feet subtracting 6 feet for digging and 3 feet for above ground level. i have already given charges for possesion map and mumty extension charges including soil test. kindly advise will piling works and the same is recommended for my house.they say that structure engineer will give u drawings for RCC piling or chooona piling where needed. i already planned to go for 2 story house but without basement as i lack funds to go for basement. when will u come at islamabad PWD office so that i can show u drawings for better opinion and assessment.



    • Mohsin Munir on April 30, 2018

      Dear Khurram

      Piling work must always be carried out strictly as per the recommendations of structural engineer. I can not further recommend or advise without looking at the structural drawings, soil test report and actual site conditions.

      I will be visiting Islamabad office before Ramazan. Stay in touch so that we can arrange a meeting.


      • Rahat Ullah Jan on October 10, 2019

        AOA Mohsin,
        I have a100 yards Plot in DHA Karaachi ( NEar Sea). Hhow much steel consume in Piling
        60ft Piling and 7 Pillers.
        Waiting for your positive respnse

        • Mohsin Munir on October 10, 2019

          Depends upon your structural drawings. There is no set standard to give a blind idea about steel in anyway. If you do not have structural drawings it is advised that you should grt the soil testing done first and the soil engineer will give his recommendations according to the test report to structural enginner who will design the steel according to those recommendations.

  • Khurram on April 5, 2018

    mohsin bahi thanks for prompt reply. im residing in korang town close to ur PWD office islamabad. Can i meet u in person at ur PWD office. can u further guide that ZAk steel in rawat is reputed or not. how can a lay man like me who does not know much about home construction will perform lab test for their tensile strength test etc and how much it cost. secondly does bahria enclave management on its own perform laboratory test for sariya quality or not. ittehad official say on phone that ZAK is making steel on manual machines and their grade is 22 not 40 is it true can u please confirm from ur sources or he said for defaming ZAK. i wont quote u at all just give humble brotherly advice. actually im afraid that builder can cheat me in these things. i will also share terms and condition of my home construction agreement once it get finalized. u r the most talented experienced honest humple person i have searched on internet so far. so much informative stuff available on ur website. God bless u. can u send me turn key sample home construction agreement for my perusal / information/ self consumption please. I will share with u once draft agreement finalized and take ur very useful advice.

    Thanks so very much mohsin bahi please share ur whats app no

    • Mohsin Munir on April 5, 2018

      Thanks a lot for your kind words of appreciation. Actually I usually visit Islamabad office twice a month, my next visit will be in mid of this month inshAllah.
      Talking about ZAK, in my last reply what I meant was that you can discuss technical reports with dealers of both brands and compare those figures. If you want to get the test done personally there are many material testing labs that provide steel bar testing and its not that costly. You can search close to you on google. And Bahria enclave management or any other housing society does not offer or provide material testing services to clients who are building their houses, they might have the testing facility but for the testing of construction material of their own projects.
      What ittehad guy is claiming about ZAK, I seriously doubt it, there can be a difference in grade but 22 seems like too much exaggerated figure on lower side. And if you are going for a turnkey contract with builder, then he should clearly mention brand name, its grade and maximum rate in his scope. For reference you can check our blog regarding Turnkey contract builder selection and agreement. We also have provided sample agreement in that blog.

  • Khurram on April 4, 2018

    aoa mohsin bahi what is a reputation of ZAK steel shaeen pipes rawat for 40 grade steel. actually im planing to build 10 marla in bahria enclave. why there is huge difference in prices i.e 86000/ton for Zak and 94000/ton in ittehad steel ZAK says that there is not much difference in quality only brand name matters. please share ur valuable expert opinion

    • Mohsin Munir on April 4, 2018

      Brand name does matter, but not that much in the rate. You should compare both in terms of their quality in lab reports. Two tests that matter in steel are tensile strength and yield strength measured in PSI or MPa. Most of the companies have mentioned and uploaded their results online on their websites. You can ask both about their lab reports for tensile and yield strength and brand with better results will have definitely more rate.
