Angle bar (besi siku) is used for frames, brackets, stairs, towers, and structural connections — and the first question buyers ask is usually: what does angle bar cost today? Because it’s sold by the kg / per length and prices track the market, the exact figure moves. This article explains what determines the angle bar price so you can compare quotes accurately.
What determines the angle bar price?
- Size & thickness. Angle bar is sold by the kg, so a wider leg (e.g. 50×50 vs 30×30) and thicker section is heavier and costs more per length. See the angle bar weight table for the kg/m of each size.
- Equal vs unequal angle. Unequal-leg profiles can differ in price depending on availability.
- Grade / standard. SS400 / SNI is the common grade; project-specific grades usually cost more.
- Mill price & market swings. Steel billet prices move with global prices and the exchange rate — the main reason prices change.
- Volume & delivery. Buying per tonne / per project is cheaper per kg; freight adds to the total.
Watch out: under-spec (“banci”) angle bar
The market is full of angle bar with thickness below nominal (e.g. labelled 4 mm but actually thinner). It looks cheap, but each length weighs less — so you actually pay more per kg and the strength is reduced. Always compare the price per kg and confirm the actual thickness.
How to get the best angle bar price
- Ask for a written quote with clear size, thickness, and grade.
- Compare per kg, not just per length.
- Check stock — ready stock is faster and often cheaper.
