Rebar bending schedule guide
A bending schedule (bar schedule) lists every unique reinforcement shape on a project — diameter, bar mark, dimensions, leg lengths, quantity, and total length. It is the bridge between structural drawings and steel procurement.
Frequently asked questions
What is the difference between a bar schedule and a BOQ?
The bar schedule is technical — shapes and lengths per mark. The BOQ is commercial — quantities and pricing. Both should reconcile to the same total tonnage.
Which diameters appear most often?
8–20 mm for RB500 work in Sri Lanka. Size reference: Steel bar sizes.
How do I estimate weight from a schedule?
Multiply each row's total length by kg/m for that diameter, then sum. Tool: Steel weight calculator.
Does RS Steel cut and bend on site?
Mill supply is straight bar in standard lengths. Cutting and bending are typically done on site or by a rebar processor. Confirm project needs via Contact.
