As-drawn plain hard drawn steel wire is used in the construction of prestressed concrete
structures. The wire is produced using a well-controlled drawing process, which increases its
tensile strength. This type of wire is used for concrete sleepers, pipes, poles, and precast
sections. The excellent tensile strength and elasticity of this wire make it suitable for
construction purposes.
BIS license ensures that these steel wires meet the safety standards. As per IS 1785 (Part 2):
1983, the standard outlines requirements related to tensile properties, dimensional tolerances,
surface condition, etc. The wire manufacturing companies must meet the Indian standards to
legally sell their products in the market. Getting the BIS license helps companies to gain
customers' trust and enhance brand value.
What is IS 1785 (Part 2): 1983?
This is the Indian Standard for Plain Hard Drawn Steel Wire for Prestressed Concrete -
As-Drawn Wire. It mentions requirements for steel wire used in prestressed concrete
applications in its as-drawn condition without stress-relieving treatment. As per the BIS (Bureau
of Indian Standards), wires are:
- Evaluated for chemical composition
- Inspected for surface quality
- Tested for tensile strength
- Checked for dimensional accuracy
Eligibility Criteria for As-Drawn Steel Wire BIS Approval
BIS authorisation under IS 1785 (Part 2): 1983 is required for businesses involved in
manufacturing, importing, or supplying Prestressed Concrete As-Drawn Steel Wire Products in
India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the concrete wires are covered under
QCO.
- Foreign Manufacturers - Need certification to export construction steel wire to India.
- Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
- Sellers/Distributors - Should only sell certified prestressed concrete wire.
Testing and Inspection Requirements
To ensure the quality of plain hard-drawn steel wire used in prestressed concrete applications,
the Bureau of Indian Standards outlines the minimum requirements under IS 1785 (Part 2):
1983. This certification ensures that manufacturers meet the performance standards for
as-drawn steel wire.
The BIS testing parameters and quality checks for the As-Drawn Steel Wire are listed below:
Steps for Plain Hard Drawn Steel Wire (Part 2) BIS License
The BIS Approval process ensures that the Prestressed Concrete As-Drawn Steel Wire meets
the required standards for proper and efficient operation. This process is set by the Bureau of
Indian Standards (BIS) and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for dimensional accuracy, mechanical strength, and overall material performance.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: BIS officials inspect the manufacturing units to verify the production process, safety measures, and quality control system.
- Grant of BIS License: If all the above requirements are satisfactorily met, BIS grants the certification license under Scheme-I.
- Use of ISI Mark:Once approved, the manufacturer can affix the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.

Marking Requirements & License Validity
Marking Requirements
After the BIS approval, the ISI Mark for prestressed as-drawn steel wire must be clearly and
permanently marked on its packaging or on the product. Along with the ISI Mark, important
details such as the manufacturer’s identification and licence number (CM/L) are required. This
ensures the product complies with all safety and quality standards. Further details are
mentioned below: :
| Requirement | Details |
|---|
| ISI Mark | Indicates that the product is BIS certified and conforms to standards |
| Standard Number | IS 1785(part 2) : 1983 |
| CML Number | Certification Marks License (CML) number issued by BIS |
| Manufacturer Details | Name of manufacturer or registered trademark |
| Batch / Date | Batch number, heat number, or manufacturing date for traceability |
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.

Conclusion
Plain hard drawn as-drawn steel wire continues to be an important reinforcement material for
prestressed concrete systems. Conformity to the conditions laid down by IS 1785 (Part 2):1983
ensures that the product has been analyzed for its quality and strength. The use of certified wire
can reduce the risk of premature material failure. It also contributes to more reliable
performance in various projects.
It is important to have a license from BIS for as-drawn steel wire manufacturing companies to
make sure that everything follows the law. EVTL India provides support for acquiring the product
certification for steel wires. The product certification helps manufacturers build trust in the
