The questions that come across our counter, answered in full and in one place.
- 40 guides

These are the questions people ask at the counter at Jay Shree Infra in Saharsa, written out so the answer does not depend on catching us on the phone. How much an 8 mm bar weighs, how many bori a floor takes, which sheet thickness a shed roof wants, what a tender expects to arrive with the load. They are written by Ajay Kumar Bageria's, who has worked the Saharsa iron and steel trade for 35 years.
Weights, sizes and grades in these guides follow IS 1786 for sariya and IS 459 for corrugated cement sheet, plus what the manufacturer publishes about its own product. Where those two do not settle a question, call and ask, the way the counter always has. The sariya weight chart was the first guide written and it still opens the list below. Two questions further down the list are answered at the counter instead, and both can be asked on the phone today.
In this category
Every guide, by material
Grouped by material, so the sariya questions sit together and the sheet questions sit together.
- TMT sariya weight chart: 5.5mm to 32mmKilograms per metre for every diameter, the formula the trade works from, and why a weighbridge can still differ from the chart.
- How many rods in one sariya bundleWhat a bundle holds, why the rod count moves with the diameter, and what to count before you sign for one.
- Fe 500 vs Fe 550D vs Fe 600What separates the grades in IS 1786, and why the drawing rather than the counter picks the one your slab takes.
- How to identify genuine ISI marked TMTWhat the ISI mark is, which sizes the quality control order covers, and where to look for it on a bundle.
- TMT needed for a 1000 sq ft slabThe method and the formula. A bar count for your own house comes from the structural drawing, not from a chart.
- What an MTC is, and when a tender needs itThe mill test certificate, what it ties a load back to, and the jobs that will not accept material without one.
- Why sariya rates changeWhat moves the rate week to week, freight, demand and the mill's own price, and why it is quoted fresh on every call instead of fixed on a chart.
- MS vs GI: where each one belongsPlain steel or galvanised, across grill, gate, shed frame and pipe, and what the extra cost of GI is buying.
- Angle, patti and square sizes for grill workThe sections a grill and gate workshop here actually cuts, and what to have measured before the call.
- Rolling shutter material: what one shutter needsShutter profile, guide channel and spring, set against the width and the height of the opening.
- Channel vs joist vs beamThree sections that get swapped at the counter, what each is used for, and how to say which one you want.
- MS pipe weight chart by size and gaugeOuter diameter and wall thickness against weight, and why a trade name for the section is not enough to order by.
- HR vs CR vs GP sheetHot rolled, cold rolled and galvanised plain sheet: the finish, the thickness and the work each one is bought for.
- Cement bags for a 1000 sq ft houseHow the quantity is worked out, and why we publish the method instead of a bori count for your plan.
- Storing cement through the monsoonHow bags are stacked and covered once the rain starts, and what damp does to a bag that has been sitting.
- Cement for a roof slab (chhat dhalai)The four cements written for reinforced work, the one the Bureau cautions against, and where on the sack the type is printed.
- OPC 43 grade vs 53 gradeWhat the grade number stands for, where 43 is enough, and where a drawing calls for 53.
- Roof waterproofing basicsThe cement side and the Dr. Fixit side of keeping a roof dry, and where each of them is used.
- Curing (tarai) after castingFour makers on this rack publish four curing periods, from 7 days to 21, and the type on the sack decides which one is yours.
- Plain vs premium cementWhat separates the two on the maker's own published sheet, and which jobs carry the difference.
- Colour coated vs GC (tina) chadraThe two roofs most sheds here end up with, and what the coating adds beside the colour.
- Roofing sheet length and overlapSheet length against the span, how much of a sheet an overlap eats, and why the roof is measured first.
- Material list for a grain godown or PACS shedThe whole list one shed eats, from foundation steel to purlins, girts and sheet, in the order it gets bought.
- Purlin and girt spacingWhat decides the spacing on a shed frame, and the numbers a fabricator will ask you for first.
- Do heat reducing (Coolshield) sheets workWhat the maker publishes about its own coating, and what a shed roof under it actually feels like in a Saharsa summer.
- Fibre sheets for daylightWhere a translucent sheet is set into a shed roof, and what it changes about the sheeting around it.
- Asbestos sheet, and the alternatives to itWhat the maker states is in the pack, and the GC sheet, colour coated sheet and fibre sheet we can supply instead.
- House construction: the order material is bought inWhat gets bought at which stage, from niv to chhat, so nothing sits on site three months before it is needed.
- Foundation (niv) material guideThe steel, cement and cover blocks a foundation takes, and the questions the mistri will ask you first.
- Grill and gate estimate for fabricatorsHow a workshop here works out material for a grill or a gate, and what to send us so the order matches the estimate.
- Binding wire (tar): gauge and quantityWhich gauge gets tied on site, how tar is sold, and how to work out what a job needs.
- Why cover blocks matter in RCCThe small block that keeps sariya off the shuttering, why it is skipped, and the sizes we keep.
- Vehicle loads: tempo, tractor and truckWhat each vehicle carries, which one a village approach road will take, and how that splits an order.
- Ordering by phone: how it works with usThe whole call, from what to keep ready to how stock, rate and the delivery slot get fixed on it.
- Branded vs local TMTWhat the word local covers on an invoice here, what changes when a mill can be named, and where each is accepted.
- Pre monsoon construction checklistWhat to finish, cover and buy before the rain reaches the Kosi belt, and what can safely wait for after it.
- Tender supply: the documents to ask forThe GST invoice, the MTC and the approved make list, and what a supplier should hand over with the load.
- How to compare material quotesReading two quotes that are not on the same basis: piece against weight, brand against label, delivered against godown.
About these pages
How these guides are written
One page at a time, and the phone in the meantime
Forty questions are on the list above and they go up one at a time, in the order people ask for them rather than the order that is quickest to write. Writing one down takes time, but the answer is never held back: ring the shop and ask it as a question, the same way every guide here started. Nothing here replaces that call, and nothing here is meant to.
Three things you will not find on any of them
A rate, first. Sariya and cement move daily, so a number written in one month is wrong by the next and only starts an argument at the counter. Second, a quantity for your own building. The structural drawing decides how much steel a slab takes, so what is given here is the method and the formula; the count for your own building comes off that drawing. Third, a performance figure we cannot attribute, such as how much heat a coated sheet keeps out. What the maker publishes about its own product, said in the maker's name, is as far as we go.
A guide is not the drawing, and it is not the stock
Guides here are written to make the call shorter, not to replace it. What is standing in the godown this morning changes by the truckload, so stock is settled on the phone and never here. Where an engineer or a mistri has specified something for your job, that specification decides it, not any guide. For what we actually keep, the sariya page carries the sizes, and the brands page carries every name that comes through the godown. The cement page and the steps from the call to delivery are both up now, and either one can still be asked on the phone instead.
Questions
FAQ
Ye guide kis kaam ke hain?
They answer the questions that come across our counter, in writing, so you can read one before you order instead of working it out mid call. Sariya weight, cement bags, sheet thickness, what a tender wants with the load. Each one ends with what to ask on the phone, because stock and today's rate only exist on the phone.
Guide padhne ke baad order kaise dein?
Ring the counter with the figure you worked out, the diameter, the grade, the thickness or the bag count, and we read it back against what is standing that morning. Coming to the call with a number off a guide saves the first two minutes of it. If the guide left you unsure, say so and whoever picks up will work it through with you.
In guides me aaj ka rate likha rahega?
No. Sariya and cement move daily, so a rate written down today is wrong by evening and only starts an argument later. Call +91 6202 967 218 with the material, the size and the quantity, and today's rate for that exact thing comes on the same call.
Ye sab likhta kaun hai?
Jay Shree Infra writes and publishes them. The trade knowledge in them is Ajay Kumar Bageria's, who has worked the Saharsa iron and steel trade for 35 years, and the shop itself was started in 2024. A figure from an Indian standard or a maker's published sheet is credited to that source, and the rest is trade knowledge from the counter.
Ghar bana rahe hain, pehle kaun sa padhein?
Start with the sariya weight chart. Steel is the first material a house eats, and it carries the weight of every diameter and the formula under it. After that, the guide on the order material gets bought in, from the niv to the chhat, which is the one that keeps money from going out too early.
