Pos-H

Pos-H is an exclusive World Premium Built-up H beam fabricated of POSCO steel plates under POSCO's strict quality control system. Optimal pricing along with guaranteed delivery and quality are realized, as well as meeting our client's requirements for the customized features.

Features/Strengths
  • Optimized : More than 440 available members enable optimized designing(350 flexural members and 90 compression members)
  • Economical : Compared to conventional Rolled H-Beam, 15 to 20% less steel is needed for a given component.
  • These cost and weight savings add up
  • Diverse : A variety of members are offered for all your needs including H-section, (i.e., H beam, ¥± beam, T beam)
  • Easy to use : All component cross sections produced in accordance with new Korean Industrial Standards (KS)
  • Yield strength of 275kN/mm2 or 355kN/mm2 for all members with compact sections
  • Yield strength of 420kN/mm2 for all webs with compact sections

PosMAC - Steel Curtain Wall

Steel curtain wall blocks the external atmosphere without bearing load applied to the building. Consisting of glass and panels attached to steel frames, steel curtain wall provides a highly premium atheistic look. Its high structural performance and good weldability allow the steel to achieve a wide range of designs. Compared to aluminum, it provides better performance in terms of structure, heat insulation, flame resistance, anti-seismic capability and soundproofing.

Features & Benefits
  • Design

    By applying robust structural capabilities, steel curtain wall can be installed higher than 12m floor height without stiffening members. These capabilities can create aesthetically-appealing, free-form facade shapes with a slimmer frame size.

  • Solutions

    Technical supports such as detailed design and performance tests can be provided from collaboration works among POSCO, POSCO International, N.I Steel.

  • Additional Systems

    With your choice of canopy, double skin, various sun-shade system, POSCO¡¯s structurally robust steel curtain wall frames give customers more design and environmental-friendly options in spite of the heavy-weight system attachments.

  • View

    Due to the stiffness and strength benefit, wide glass and relatively slim frames improve openness assessment in Atrium, Lobby, and Sky-light.
