PSQCA Certification for Steel Bars (Rebar)

Steel reinforcement bars are on the compulsory list of the Pakistan Standards & Quality Control Authority (PSQCA). If you melt, roll or re-roll deformed bars, or sell them under your own brand, each product needs a PSQCA Certification Marks licence before it reaches the market. Under section 14 of the PSQCA Act, 1996, manufacturing, storing or selling a mandatory item that does not conform to its Pakistan Standard is prohibited.

PSQCA does act on this. In December 2022 its team seized hundreds of tons of deformed bars from six unlicensed mills in Lahore’s Daroghawala area and stopped their production. Large producers have also complained publicly that a large share of the bars sold in Pakistan do not meet the standard, and, as Dawn reported, a study after the 2005 earthquake identified substandard steel as a major factor in building collapses. This guide explains which standards apply to rebar, what they test, and what a mill needs in place to get licensed and stay licensed.

The Pakistan Standards for steel bars

Two Pakistan Standards cover most of the reinforcement bars made and sold in the country:

Standard	What it covers	Notes
PS 1879	Deformed and plain carbon-steel bars for concrete reinforcement (metric)	The standard most local mills certify against. The 2018 revision sets out how the steel must be made, not only how the finished bar must perform.
PS 1612	Steel for the reinforcement of concrete: weldable ribbed reinforcing steel in bar, coil and decoiled form	Earlier editions covered cold-worked deformed bars. The 2014 revision covers weldable ribbed steel and excludes bars made by re-rolling finished products.

Confirm with PSQCA which standard, and which revision, applies to your exact product before you plan your process or print your tags. Standards are revised from time to time, and the licence is issued against a specific one.

Who needs a PSQCA licence for steel bars?

• Integrated mills that melt scrap or sponge iron, cast billets and roll bars
• Rolling and re-rolling mills that buy billets and roll them into deformed bars
• Brands and traders that sell bars rolled for them by another mill
• Importers of steel reinforcement bars

The licence is issued for a product, made at a particular factory, under a particular brand. A trader cannot rely on the rolling mill’s licence for its own brand, so check whose name is on the licence before you sign a supply agreement.

What the steel bar standards check

How the steel is made. PS 1879-2018 requires bars to be rolled from properly identified heats of mould-cast or strand-cast steel, made by electric arc furnace or induction furnace with a ladle refining furnace, by the basic oxygen process, or by the open-hearth process, using quality meltable scrap or its substitute. Rolling re-rollable scrap or ship-breaking plates straight into bars does not meet this requirement. This is the clause behind most of the steel industry’s complaints about substandard bars.

How the bar performs. Typical tests include:

• Yield strength and tensile strength, which must meet the minimum for the bar’s grade.
• Elongation, which shows whether the bar will stretch rather than snap under load. This is where bars rolled from scrap plate most often fail.
• Bend and rebend tests, which show whether the bar cracks when bent around a mandrel.
• Chemical composition, including carbon, manganese, phosphorus and sulphur, and carbon equivalent where the bar is sold as weldable.
• Mass per metre, so that a bar sold as 16 mm actually carries the steel a 16 mm bar should.
• Deformations, meaning the height, spacing and angle of the ribs that grip the concrete.
• Marking, so the producer, size and grade can be identified on the bar itself.

Grades. The two grades most widely sold in Pakistan are Grade 40 and Grade 60, with Grade 60 specified for most structural work. Check the grade designations, minimum yield values and bend requirements in the revision of the standard you are certified against, and make sure your rolling marks show the grade correctly.

Why steel bars fail PSQCA testing

Most failures come from a short list of causes:

• The wrong raw material. Bars rolled directly from ship plate or re-rollable scrap have unpredictable chemistry and often fail elongation and bend tests.
• No secondary refining. An induction furnace without a ladle refining furnace leaves phosphorus and sulphur too high.
• Underweight bars. Rolling slightly under size saves steel, but it fails the mass-per-metre requirement and short-changes the buyer.
• Poor temperature control in the mill, including inconsistent quenching on thermo-mechanically treated lines, which produces bars that vary in strength along their length.
• Missing or wrong marks, which make the bar impossible to trace and can count as a labelling failure on their own.

If you also supply cement to the same projects, our guide to PSQCA certification for cement covers the other construction material that inspectors and buyers check most often. For the electrical side of the same projects, see our guide to PSQCA certification for electric cables and wires.

How the licence process works for a steel mill

PSQCA uses the same Certification Marks route for every compulsory product, which our PSQCA registration guide explains in full. For a steel mill, each stage looks like this:

1. Application. You apply for each product and standard with the supporting documents, and PSQCA scrutinises and registers the file.
2. Factory evaluation. Officers visit the plant. Expect them to look at scrap or billet reception, the melt shop and ladle refining, casting and heat identification, the rolling mill and any quenching line, marking rolls, bundling and tagging, and your laboratory.
3. Sampling. Samples are drawn from production or from finished stock.
4. Testing. Samples are tested in your laboratory and at PSQCA’s laboratories against the standard.
5. Licence. If the product conforms, the licence is issued and you may use the mark.
6. Surveillance. PSQCA carries out periodic inspections and tests samples taken from the mill and from the market.
7. Renewal. The licence is renewed periodically, and can be suspended or cancelled if the product stops conforming.

If your bars have already failed a market sample, or PSQCA has sealed your mill, our guide to responding to regulatory action sets out what to do first.

Documents and laboratory you will need

The core file is the same as for any PSQCA product: proof of business registration, a process flow chart, the quality manual and quality plan, raw-material specifications, a list of test equipment with calibration records, details of QC staff, test reports showing conformity, and factory layout and location plans. Our PSQCA certification checklist sets out every item. If you have not yet registered the business, our SECP company registration guide covers that step.

For a steel mill, inspectors look hardest at heat-wise chemical analysis, a universal testing machine for tensile, yield and elongation, bend test equipment, and a reliable way of weighing bars to check mass per metre. Our QC laboratory guide covers setting up the lab, and our article on calibration and traceability explains why an uncalibrated testing machine undermines every result it produces. Confirm the current application fee directly with PSQCA before filing, as fees are revised from time to time.

A new or expanding melt shop also needs environmental approval, which has to be in place before construction rather than after. Our guide to permits by stage of an industrial project explains the order.

Why your buyers will ask for the licence

Contractors on public works usually have to prove that the materials they use conform to the specified standards, and a bid or invoice backed by unlicensed steel is easy to reject. Our article on why government bids are rejected shows how often compliance documents decide a tender. A valid PSQCA licence, with test certificates for each heat, makes your bars easier for these buyers to approve.

Tips for steel bar producers

• Keep a heat number on every bundle tag, and keep chemical and mechanical test results for every heat.
• Check the weight of each size several times per shift, not only at the start.
• Calibrate the universal testing machine on schedule and keep the certificate where inspectors can see it.
• Retain samples from each heat, so that you can answer a market-sample failure with evidence.
• Apply for each standard you sell under. Bars sold to PS 1879 and to PS 1612 are certified separately.
