Steel bar and rebar for sale in South Africa

Updated 4 November 2026

Rebar in South Africa costs from about R 49 for an 8 mm bar of 6 m and up to about R 225 for a 16 mm Y-bar of the same length, with round bar and 12 mm bars sitting between those prices. These are approximate per-bar ranges from sellers' websites in November 2026. For a price on your exact list, describe the steel, sizes and quantities on BlaBlaPrice, and sellers reply with their own offer.

Standards and what to check on the bar

Steel bars for reinforcing concrete must comply with SANS 920, and welded mesh with SANS 1024, according to one supplier's guide. Ask for a batch certificate with every delivery. The national regulator for compulsory specifications works to keep sub-standard products from being sold, but checking is still your job: confirm the diameter marked on the bar and the grade, which listings show as 450 MPa for Y-bars. Plain mild steel bar and deformed high-strength bar are the two types on the market, and Y-bars are the deformed kind.

Cutting, bending and timing

If you need steel cut and bent to a bar bending schedule, some suppliers offer cut and bend to SANS 282 in stock lengths and grades from 250 to 500 MPa, with batch certificates. Ask whether your supplier does this before you order loose lengths. Plan the order for the summer months (December to February) so the steel is on site before the pour, and allow for slower curing in the cooler winter months from June to August.

How steel is priced and delivered

Prices are quoted per bar, usually for a 6 m length, and some listings give 6.5 m. Ask for the total with delivery to your address, and whether the price is per bar or per tonne. Metric units apply throughout: millimetres for diameter, metres for length, kilograms for weight. Confirm delivery to Johannesburg, Cape Town, Durban, Pretoria or Gqeberha before you agree on a price.

What to write in your request

Say which steel product you need (rebar, round bar, flat bar or stainless), the diameter in millimetres and the length in metres. Give the quantity in bars, the steel grade if an engineer specified one, and whether you want new steel. Add the delivery address and your budget. If you have a bar bending schedule, include it, so sellers can quote the right cut lengths.
