EMCOCABLES S.A., was founded in March of 1960 by a group of Colombian industrialists and the Paulsen Wire Rope Corporation, a North American steel wire rope manufacturer. This company contributed their technology as well as technical expertise to EMCOCABLES.

The decade of the 70's marked the initiation of product diversification. This diversification included such products as: tire bead wire, wires and strands for the pre-stressing of concrete, galvanized wire for electrical conductors, overhead static (ground) wire, as well as other wires and strands for different uses.

At the end of 1988, EMCOCABLES began production of aluminum clad steel wire and strands for electrical uses, with extra high resistance against corrosion.

EMCOCABLES S.A. mainly exports 50% of its total production; the company sells to over 20 countries. These products are always supported and backed up by quality, fulfillment and excellent performance in use.

At a national level, companies such as ISA, Public Companies of Medellin, Antioquia Energy Company, Miners of Antioquia, Porticos, Codensa, ECOPETROL, Intercor-El Cerrejon, Drummond, Goodyear of Colombia, and Michelin are among the most notable of the many companies who put their trust in the excellent performance of EMCOCABLES products.

Steel wires & strands for prestressed concrete

Steel wires

EMCOCABLES manufactures a wide variety of high carbon wires. Included are wires for reinforced concrete used as structural support in the pre-stressed, post tension and pre-cast industries. EMCOCABLES produces in accordance to all internationality recognized specifications such as ASTM, UNE, NTC and others. The wires are used specifically for pre-tensed structures.



Generally, strands are comprised of one central wire and six external wires rolled helicoidally around the central wire. These strands are manufactured bright or galvanized conditions and/or extruded with high-density polythene, according PTI and other recognized standards.

Standards NTC 2010 and ASTM A 416.


Properties of Coating

The Zinc used for the coating of the wires that comprise galvanized strand is of the highest purity grade, SHG (Special High Grade), in accordance with ASTM B 6 standard. This guarantees the formation of a Zinc-Iron bond sufficiently strong in order to achieve the most efficient galvanic protection of the steel.

The mass of the Zinc coating in g/m2 should be homogenous over the entire length of the wires, meeting the requirements and/or standards previously agreed up with the client, for example: ASTM A 475, BS 183 (British Standard), ASTM A 363, EMCOCABLES standards and/ or client standards.

In addition to 7 wire strands, EMCOCABLES manufactures two wire strand and three wire strands, based on customer and/or international standards. EMCOCABLES also produces indented strands based on the ASTM A 886 standard.

Extruded strands

The break load properties, 1% elongation load, lay length, and diameter are the same required properties as the uncoated strand. These are properties that are established by the ASTM A 416 standard and shown in tables 2 and 3.

The specifications for the coating established by the Post-Tensioning Institute are as follows:

Coating (jacket) Properties

  • High resistance and durability to avoid damage to the strand during manufacturing, transport, installation and or tensioning.
  • Hermetic seal over the entire length of the coating.
  • Will not react to concrete, steel, nor the corrosion inhibitor (grease).
  • The minimum thickness of the coating (jacket) should not be less than 1.00mm (0.040”) for high density polyethylene and/or polypropylene, of high density or its equivalent if other materials are requested.
  • The internal diameter of the coating (jacket) should be at least 0.76mm (0.030”) greater than the maximum diameter of the strand.

Corrosion Inhibitor

The covering for the corrosion inhibiting materials must have the following properties:

  • Must be chemically stable and not react with steel, the jacket material, or concrete.
  • Must have the necessary polarity to reject humidity.
  • Provide adequate lubrication between the strand and jacket.

Products for electrical & telecommunication uses

Steel wires and strands coated with type AS aluminum for type ACSR/AS/AW electrical conductor cores steel wires.

The high mechanical resistance, good conductivity, excellent resistance to corrosion, and compatibility with solid aluminum cables, make AS/AW wires and strands very attractive as a core for ACSR (ACSR/AS/AW) type conductors.

When the aluminum clad wires are used as reinforcing elements, they combine a  high mechanical resistance characteristics with their electrical conductivity improving the performance of the conductors.

The wires are manufactured in accordance with the AST B 502 standard, and the strands are manufactured in accordance with the ASTM B Standard.

Steel wires & strands for ACSR type electrical conductor cores

With the rapid development of power plants, the ACSR (Aluminum Conductor Steel Reinforced) presents itself as the standardized conductor for energy transmission. The galvanized wire and the galvanized cable for ACSR must exhibit consistency, both mechanically and physically  due to the fact that it constitutes the primary support for aluminum conductors that span large distances.
