Rebar

Rebar (reinforcing steel) — round-section bars with ribbed or smooth profile, used to reinforce reinforced-concrete structures. They take the tensile loads that concrete itself cannot carry.

E-Metall has 90 active SKU. We always stock fast-mover sizes Ø 12, 14, 16, 20, 25 mm grade A500C — same-day shipment. For large volumes — direct factory shipment within 7—14 days.

Classification & types

A500C (hot-rolled, weldable)

The most common grade on the market. Yield σy ≥ 500 MPa, ultimate σu ≥ 600 MPa. Used as the working reinforcement of load-bearing structures: foundations, columns, beams, slabs. Weldable without loss of strength by resistance and arc welding. GOST 34028-2016.

A1 (A240, smooth)

Smooth profile, σy ≥ 240 MPa. Used as distribution reinforcement, stirrups, mounting ties. The smooth surface gives less bond with concrete — so it is not used as working reinforcement in load-bearing nodes. GOST 5781-82.

A3 (A400, ribbed)

Gradually being replaced by A500C. Used in legacy projects and refurbishment. GOST 5781-82.

B500 (cold-deformed)

Made by cold-drawing, supplied in 1000 m coils, diameter 5—12 mm. Used in reinforcing meshes, light screed reinforcement, masonry. GOST 52544-2006.

Selection guide

Working reinforcement for load-bearing structures (foundations, columns, transom beams, beams) — A500C is mandatory. Tenders usually require this grade specifically.
Stirrups, mounting ties, distribution reinforcement — A1 (smooth); smaller-diameter A500C is acceptable.
Mesh for screeds and masonry — B500 in coils or pre-fabricated masonry mesh.
Seismic zones (Almaty, Taldykorgan) — A500C with confirmed impact toughness at −40°C.
State tenders — specify “A500C per GOST 34028-2016” explicitly and attach the current factory quality passport.

Storage, acceptance, transport

Store in a dry place, on supports, avoiding direct contact with the ground and water
Light surface rust is allowed and is not grounds for refusal of the batch (GOST permits this)
Before pouring concrete, clean rebar of loose rust and oil with a wire brush or sand-blasting
Transport in 1—5 t bundles, wired strapping
Cutting to size — at our facility, see metal cutting

FAQ

Q. What is the difference between sized and non-sized rebar?

Sized — exact length 11.7 or 12 m, 5—8% more expensive. Non-sized — random length within the tolerance (5.5—12 m), cheaper but generates more cutting waste. For concrete works, sized is preferred.

Q. Can A500C be replaced with A3 in a project?

Only with the designer\u2019s written approval. The grades have different weldability and ductility. On tender sites, unauthorised substitution leads to rejection at acceptance.

Q. How much rebar per 1 m³ of concrete?

It depends on the structure: foundations — 80—120 kg/m³, floor slabs — 100—150, columns — 200—300. Exact figures — by the structural drawings.

Q. Do you fabricate ready rebar cages?

Yes, but not in series. Per project — we calculate, bend and weld to client drawings. Confirm with a manager via the feedback form.
