What is MS Flat (Iron Patti / Loha Patti)?

MS Flat is a rectangular mild steel flat bar used in fabrication, frames, base plates, supports, brackets and general construction work. It is commonly called Iron Patti or Loha Patti in the market.

How do you calculate MS Flat weight per meter?

Use: Weight (kg/m) = Width(mm) × Thickness(mm) × 0.00785. Multiply by length (m) to get total weight.

Why does MS Flat weight chart matter for billing?

Steel is billed by kg/ton. The weight chart helps estimate total kg before dispatch, so budgeting, transport load and fabrication costing stay accurate.

Can actual weight differ from chart weight?

Yes. Chart values are theoretical. Due to rolling tolerances and coating differences (if any), actual invoiced weight can vary slightly. Always order by size and verify material on receipt.

MS Flat Weight Chart (kg/m) + Quick Calculator

In steel buying, the shape is simple — the weight is what decides the bill. Whether you call it MS Flat, steel flat bar, Iron Patti, or Loha Patti, the chart helps you estimate costs, plan transport load, and avoid “invoice shock” at site.

Flats are used across construction and fabrication because they offer straight edges, uniform thickness, and easy welding/cutting. But sizes vary widely, so a size-wise chart becomes the fastest way to plan budget + quantity + handling.

Quick Notes (Read Before Ordering)

Always order by size (Width × Thickness) and length.
Billing follows kg/ton, so weight per meter matters.
Fabricators use charts to estimate frames, gates, racks and supports.
Transport planning becomes easier when total kg is known.

Supplier tip: Ask for size confirmation and a clean weight estimate. For product details, see MS Flat product page.

Weight Formula (Simple and Reliable)

Use this standard flat-bar formula to estimate theoretical weight:

Weight (kg/m) = Width(mm) × Thickness(mm) × 0.00785

For total length: Total kg = (kg/m) × Length(m)

Note: Chart values are theoretical. Actual invoiced weight can vary slightly due to rolling tolerances. Use the chart for estimation and verify on receipt.

Reality check: If a flat is lighter than expected, it can impact stiffness in fabricated parts. If it’s heavier, it impacts billing. This is why the chart below is used daily by buyers and fabricators.

How to use this chart: pick your width × thickness → take kg/m → multiply by total meters. This gives an accurate estimate before dispatch and reduces misunderstandings at billing time.

Where MS Flats Are Used (and Why Weight Matters)

MS flats are used across construction and manufacturing because they offer consistent geometry for fabrication. You’ll commonly find them in frames, supports, base plates, brackets, racks, grills, and general industrial parts.

Weight matters because a “similar looking” flat can be very different in total steel content. Choosing too light can reduce stiffness; choosing too heavy increases cost unnecessarily. The chart keeps selection clean and predictable.

Common Mistakes Buyers Make With MS Flat Weight

Comparing only width and forgetting thickness (big cost difference).
Mixing kg/m and total kg during quotation discussions.
Budgeting by “piece count” instead of converting to kg.
Not accounting for cutting wastage in fabrication estimation.
Using random old charts without checking tolerances on delivery.

Simple safe practice: confirm size, calculate kg, then compare rates. This keeps procurement transparent and avoids last-minute site confusion.

FAQ

Is MS Flat same as Iron Patti / Loha Patti?

Yes, in market language MS Flat is often called Iron Patti or Loha Patti. Technically it’s a rectangular mild steel flat bar used for fabrication and construction.

What is the fastest way to estimate MS Flat total weight?

Use the chart’s kg/m value and multiply by total meters. Or use the calculator above for instant total kg.

Why do two suppliers quote different totals for the same size?

Check if thickness or length differs, or if tolerances/rolling variations changed actual weight slightly. Always match specs and compare like-to-like.

Do I need a weight chart even if I buy in tons?

Yes. Weight chart helps you estimate how many meters/pieces come in a ton for a given size—useful for planning fabrication and site consumption.
