Vizag Steel (RINL) Weight Chart — TMT, Angles, Channels and Beams
Vizag Steel (RINL) produces TMT bars, angles, channels, and beams at its Visakhapatnam integrated steel plant — all conforming to relevant BIS standards.
- TMT bars follow the D²/162 formula per IS:1786:2008 — a 16 mm bar weighs 1.58 kg/m
- Structural sections (angles, channels, beams) conform to IS:808:1989 for dimensions and mass
- RINL is a Government of India enterprise — mill test certificates carry PSU credibility for government infrastructure projects
Vizag Steel weight chart — covering the full RINL product range from 8 mm TMT bars to ISMB 600 beams — has been one of the harder reference pages to find online. RINL's own site distributes this data across multiple PDFs that are poorly indexed and mobile-hostile. This page consolidates the four main product categories into clean, searchable tables with IS-standard citations.
About Vizag Steel (RINL)
Rashtriya Ispat Nigam Ltd. (RINL), marketed as Vizag Steel, is a government-owned integrated steel producer located in Visakhapatnam, Andhra Pradesh. It is one of the few Indian steel plants with a shore-based location, enabling direct ore imports by ship. RINL produces a broad range of long steel products — TMT rebars, wire rods, structural sections, and rounds — primarily for the construction and infrastructure sectors. Its Fe 500D and Fe 550D TMT bars carry BIS certification and are specified on government infrastructure projects across South and Central India.
For procurement purposes, Vizag Steel ka weight chart below uses the same IS-standard formulas as any other BIS-certified producer. The weight per metre is a function of section geometry, not the brand — so these values apply directly to any conforming Vizag Steel product.
TMT Bar Weight Formula
Formula: Weight (kg/m) = D² / 162
- D
- Nominal diameter of the TMT bar, in millimetres
- 162
- Derived constant — from π × ρ_steel / 4, with steel density 7850 kg/m³ and unit conversions, per IS:1786:2008

Worked Example — Column Reinforcement with Vizag Steel Fe 500D
A civil contractor in Hyderabad is reinforcing columns for a four-storey residential building. The structural drawing specifies Vizag Steel Fe 500D, 16 mm diameter TMT bars. He needs to order 200 bars of 12 m length and confirm the total tonnage for procurement.
Step 1 — Calculate weight per metre:
Weight = D² / 162 = 16² / 162 = 256 / 162 = 1.58 kg/m
Step 2 — Calculate weight per bar:
Weight per bar = 1.58 × 12 = 18.96 kg per bar
Step 3 — Calculate total order weight:
Total = 200 × 18.96 = 3,792 kg = 3.79 MT
Step 4 — Plan logistics:
At 3.79 MT, the order requires a medium truck (Ashok Leyland 1615 or similar, rated 7.5 MT). The contractor confirms one trip is sufficient and requests the RINL mill test certificate for the Fe 500D grade to submit with the project quality records.
