An MS equal angle — also called an angle bar, angle iron, or L-section — is a hot-rolled mild steel section with two legs of equal width meeting at a right angle. It is classified under IS 808:1989 for dimensions and IS 2062:2011 for material grade. When searching for an MS angle weight chart in kg, IS 808 is the standard reference for all Indian hot-rolled equal angles.
MS angles are specified by three numbers: leg size × leg size × thickness. A 50×50×6 angle has both legs 50mm wide and a wall thickness of 6mm. The weight per metre changes significantly with thickness — making an accurate MS angle weight chart essential for BOQ preparation, freight estimation, and procurement pricing.
Decorative grilles, furniture frames, lightweight gate infills, cable trays, partition frames, and exhibition displays. Low structural load. Easy to weld and handle on site.
Gate main frames, window grilles, stair railings, shelf supports, solar mounting structures, and general-purpose industrial fabrication. The most commonly stocked thickness.
Roof trusses, welded connection gussets, structural bracing, column bases in industrial sheds, heavy machine bases, and primary transmission tower leg members.

The Nominal size is not enough — a "50×50" angle can come in thicknesses from 3mm to 8mm with up to 151% weight difference between them. Always specify all three dimensions: leg × leg × thickness. Verify with a vernier caliper on delivery, measuring at the mid-leg position.
Leg Size A · Thickness t · Root Radius r1 · Key Parameters for the Weight Chart
Every value in the MS angle weight chart in kg is derived from two key dimensions: the leg size (A) in mm and the thickness (t) in mm. The diagram below shows how these relate, and how the IS 808 designation works.
The weight of an MS equal angle depends on two dimensions: the leg size A (both legs equal in an equal angle) and the thickness t. The root radius r₁ adds a small amount of material at the internal junction — this is why IS 808 tabulated weights are marginally higher than the simplified formula result.
4.47 kg/m · 26.82 kg per 6m Piece · IS 808 Designation: ISA 50×50×6
The MS angle 50×50×6 is the most structurally significant thickness for the 50mm leg size. At 4.47 kg/m, it is classified as a structural-grade equal angle — used in roof truss members, welded connection gussets, column bracing, and support brackets carrying point loads. The table below shows the full 50×50 family so you can compare weight differences across thicknesses.
Weight per metre: 4.47 kg/m | Per 6m piece: 26.82 kg | Per 12m piece: 53.64 kg
Pieces per tonne (6m lengths): ≈ 37 pieces | IS designation: ISA 50×50×6
Material grade: IS 2062 E250 (Fe410W) | Root radius r₁: 8.0 mm | Area: 5.69 cm²
The 6mm wall makes the 50×50×6 meaningfully stiffer and stronger than the 3mm or 5mm variants. Key IS 808 sectional properties:
• Moment of Inertia (Ixx): 11.1 cm⁴
• Section Modulus (Zxx): 3.10 cm³
• Radius of Gyration (rxx): 1.40 cm
• Centre of Gravity (Cx = Cy): 1.52 cm from back of leg
These values are relevant when a structural engineer is calculating bending capacity, buckling resistance, or deflection for truss members, gusset connections, or bracing frames.
The 50×50×5 weighs 3.77 kg/m vs the 50×50×6 at 4.47 kg/m — 18.6% more steel per metre in the 6mm version. Choose the 6mm when:
• The angle carries a calculated point load or shear in a welded joint
• It forms part of a roof truss chord or diagonal bracing member
• The structural drawing explicitly calls out 50×50×6 or ISA 50×50×6
• The joint requires fillet welds ≥ 6mm throat to carry the design force
For lightweight gates, decorative infills, or non-structural frames, the 50×50×5 is sufficient and more economical.

To convert values from this MS angle weight chart in kg per metre to kg per foot, multiply by 0.3048. Example: 50×50×6 at 4.47 kg/m = 4.47 × 0.3048 = 1.36 kg/foot.
Bundle weight example: 50 pieces × 6m × 4.47 kg/m = 1,341 kg = 1.341 MT. Bookmark this MS angle weight chart in kg for quick on-site reference.
Formula for Sizes Not in the MS Angle Weight Chart in KG — or for Verification
If you need to calculate the weight of an MS angle size not listed in the MS angle weight chart in kg above — or need to verify a declared wall thickness — use the standard engineering formula. This is the same formula behind every value in the chart:
To calculate total order weight from the MS angle weight chart in kg:
Total Weight (kg) = Weight per metre (kg/m) × Length (m) × Number of pieces
Example: 100 pieces of 50×50×6, each 6 metres long = 4.47 × 6 × 100 = 2,682 kg = 2.682 MT. Always cross-check with the MS angle weight chart in kg before placing a bulk order.
