Featured Work

Steel Curtain
Wall

Steel Curtain Wall is an outer wall system where POSCO’s steel materials are used. Glass and panels are attached to
horizontal/vertical steel frames.

Excellent structural stiffness compared to Aluminum frame with good insulation and
anticrime or antifire functions

Produce roll-formed cross section developed by POSCO, which can realize zero-energy buildings.

Roll-formed type applied to Songdo POSCO Green Building: thermal transmittance 0.91 W/m2K (42mm triple double-sided
low-E glazing window system)
* Standard of domestic apartment’s envelop insulation U value (2.10 W/m2K)

Use POSCO’s high-end steels (POSMAC)

Excellent corrosion resistance and antirust compared with GI(galvanized iron) steel sheets(based on PSCW roll-formed type).

Install the frames manufactured in a partner’s factory at a site (technical support & quality control).

Perform win-win project models for SMEs through cooperation between family companies.

Steel Curtain Wall VS Aluminum Curtain Wall

Various Facades

Response to the freeform architecture trend with
diversified exterior.
* AL curtain wall welding impossible, separate
support needed

Insulation

Changes in the building market environment: eco-friendly,
passive houses, etc.
* Good thermal transmittance of 16% or more compared
to AL curtain wall

Structural Stiffness

A possible structural role without stiffening even
in more than 6-meter high-ceiling buildings.
* AL curtain wall stiffeners and structural
support needed

Safety (Earthquake-proof, Fireproof)

Earthquake-proof, fire safety: 2-4 times better

Architectural
Skin

By supplying highly functional panel system tailored to the market trends (eco-friendly, energy saving, and safe), we take the lead in the interior and exterior building material markets.

General Panels

Sandwich panel, metal panel: exterior material products in response to diverse markets.

Functional Panels

Prefabricated Panel: This is a system of assembling factory-made panels in sites with the purpose of securing construction
and reducing the period and expenses of construction.
Vacuum Insulation Panel: The use of vacuum insulated materials as inner fillers improves thermal conductivity by 8~10 times(0.0045 W/㎡K)
Fireproof Panel: Organic materials with high insulation are used as inner fillers to enhance antifire function.
Self-cleaning, Anionic Panel: New steel grade-based panel with nano materials; UV ray, high-gloss coated steel sheets

Other Products

BIPV: Combined with renewable energy; the building integrated photovoltaics system for envelop.
