Steel Rebar Guide for Cambodia: Grades, Sizes & Prices
What Cambodian builders should know about rebar grades, common sizes, current prices, and how to spot low-quality steel on site.
Steel Rebar Guide for Cambodia: Grades, Sizes & Prices
Reinforcement steel — or rebar — is one of the biggest line items in any Cambodian construction budget. Choosing the wrong grade or accepting under-sized bars can weaken columns and slabs for the life of the building.
Common rebar grades in Cambodia
Most sites in Phnom Penh and Siem Reap use two grades:
- SD40 (Grade 40) — yield strength around 400 MPa. Suitable for small villas and boundary walls.
- SD50 (Grade 50) — yield strength around 500 MPa. Standard for multi-storey houses, shophouses, and commercial buildings.
Always ask the supplier for the mill test certificate. Reputable stores such as those listed on BuildHub will provide it without hesitation.
Standard bar sizes
| Diameter | Typical use |
|---|---|
| 6 mm | Stirrups, ties |
| 10 mm | Slab mesh, small beams |
| 12 mm | Beam main bars, columns for 1-storey |
| 16 mm | Columns for 2–3 storey houses |
| 20–25 mm | Main columns of shophouses and villas |
How to spot low-quality rebar
- Check the rolled brand mark — genuine bars carry the mill logo every metre.
- Weigh a 1 m sample — a 12 mm bar should weigh close to 0.888 kg/m.
- Reject bars with heavy rust flakes or bent ends.
Getting the best price
Rebar prices in Cambodia move with global steel and USD/KHR rates. Compare quotes from at least three suppliers on BuildHub before ordering a full truck. Bulk orders above 5 tonnes usually get 3–6% off.
