Short answer: deformed steel bar (rebar) costs roughly ₱37–47 per kg in the Philippines, depending on diameter — smaller bars run higher per kg because more of the cost is processing, not raw steel. By standard stocked length: a 10mm × 6m bar runs about ₱175, a 12mm × 6m bar about ₱218, and a 16mm × 6m bar about ₱355. Prices below are per-piece figures for common sizes, cross-checked against per-kg pricing so you can compare across suppliers regardless of how they quote.
10mm × 6m: ₱175 (~₱47/kg) · 12mm × 6m: ₱218 (~₱41/kg) · 16mm × 6m: ₱355 (~₱38/kg) · 20mm × 7.5m: ₱705 (~₱38/kg)
Rebar suppliers quote price in one of two formats, and knowing which one you're looking at avoids the usual confusion:
Per Piece (Standard Length)
Most Philippine suppliers and hardware stores quote a flat price per bar at its stocked length — typically 6m, 7.5m, or 9m. This is the number you'll see on a price list or receipt, and it's the easiest to compare when you're buying whole bars.
Per Kilogram
Larger orders, direct-from-mill purchases, and cross-supplier comparisons are usually done per kg — the fairer basis when bar lengths or cut sizes differ. Every per-piece price below also converts to a per-kg figure so you can compare a 6m quote against a 9m quote apples-to-apples.
| Size | Grade | Length | Price / piece | ≈ Price / kg |
|---|---|---|---|---|
| 10mm | PNS 280 (Grade 40) | 6.0m | ₱175 | ₱47/kg |
| 12mm | PNS 280 (Grade 40) | 6.0m | ₱218 | ₱41/kg |
| 12mm | PNS 280 (Grade 40) | 7.5m | ₱257 | ₱39/kg |
| 12mm | PNS 280 (Grade 40) | 9.0m | ₱306 | ₱38/kg |
| 16mm | PNS 420 (Grade 60) | 6.0m | ₱355 | ₱38/kg |
| 16mm | PNS 420 (Grade 60) | 7.5m | ₱453 | ₱38/kg |
| 16mm | PNS 420 (Grade 60) | 9.0m | ₱541 | ₱38/kg |
| 20mm | PNS 420 (Grade 60) | 7.5m | ₱705 | ₱38/kg |
Once a bar is 12mm or larger, per-kg cost settles into a tight ₱37–41/kg band regardless of grade or length — the real spread is at 10mm, where processing cost weighs more per kilo.
Pick a bar size and length, enter how many pieces you need, and get total weight and indicative cost.
Philippine rebar is graded under PNS 49, the national standard for deformed and plain steel bars for concrete reinforcement. The grade number refers to minimum yield strength, not quality — a Grade 40 bar isn't a "lesser" bar than Grade 60, it's simply designed to a different strength, and a structural engineer specifies which one a given column, beam, or slab requires.
PNS 230 (ASTM Grade 33) — Structural Grade
The lowest yield strength of the three, used for lighter structural elements. Less common on new residential work today, where Grade 40 has become the practical default.
PNS 280 (ASTM Grade 40) — Intermediate Grade
The most commonly specified grade for residential slabs, footings, and columns in the Philippines — the default assumption on most house and small-commercial structural drawings unless noted otherwise.
PNS 420 (ASTM Grade 60) — Hard Grade
Higher yield strength for the same bar diameter — used where a design calls for more capacity without oversizing the bar, common in larger commercial and multi-storey structures.
Never substitute a lower grade for what a structural drawing specifies, even at the same diameter — yield strength, not bar size alone, is what the design calculation is based on. If a supplier is out of the specified grade, check with the engineer of record before swapping.
Unlike CHB or lumber, rebar is a globally traded commodity — its price tracks international steel and iron ore markets as much as local supply, which is why it moves faster and less predictably than most other Philippine construction materials:
Because of this volatility, treat the figures on this page as a starting point for budgeting, not a fixed quote — always confirm current pricing with your supplier before finalizing a material order, especially for large-volume purchases where even a ₱1–2/kg swing adds up quickly.
Per-piece prices are cross-referenced from published Philippine hardware and steel-supplier price lists (2026), converted to per-kg using PNS 49 theoretical bar mass. Rebar pricing moves faster than most construction materials due to global steel markets — always confirm current rates with your supplier, especially for bulk/mill-direct orders where volume pricing applies.
How much does rebar cost per kilo in the Philippines?
Roughly ₱37–47 per kg depending on diameter — smaller (10mm) bars run higher per kg, mid-to-large bars (12mm–20mm) cluster around ₱37–41 per kg.
How much does a 10mm rebar cost per piece?
A 10mm × 6m bar, the standard stocked length, costs approximately ₱175 — about ₱47 per kg.
What's the difference between Grade 33, 40, and 60 rebar?
They're PNS 230, PNS 280, and PNS 420 respectively — different minimum yield strengths, not different quality tiers. A structural engineer specifies which grade a given member requires; never substitute without checking.
How much does rebar weigh per meter?
10mm — 0.617 kg/m, 12mm — 0.888 kg/m, 16mm — 1.578 kg/m, 20mm — 2.466 kg/m (theoretical mass, PNS 49).
AEDO's design-build service includes material sourcing and quality control for rebar and every other structural component — under one contract, for projects located in Negros Oriental. For projects elsewhere in the Philippines, AEDO provides complete structural design with remote engineering oversight, and can refer you to a vetted local contractor for the actual construction.
