Rethinking Cost and Value in Steel Curtain Wall and Window Systems

Beyond design appeal, the market perception of steel curtain walls and window systems is undergoing significant change. In this article, we explore how longevity, aesthetics, and now cost-efficiency are shifting buyer preferences.

✅ Steel vs. Aluminium: A New Cost Equation

Traditionally, steel curtain wall and window systems were known for premium pricing — often 2-3 times that of aluminium systems. However, their superior lifespan (over 30 years), customised aesthetic, and structural reliability made them the go-to solution for high-end residences, luxury hotels, and commercial projects.

Today, GNT has changed the game. Through ongoing R&D and process innovation, we have significantly reduced manufacturing and equipment costs. As a result, our steel systems are now more affordable than comparable aluminium systems.

This breakthrough redefines the value proposition of steel façades: clients can now enjoy higher quality and better aesthetics at a lower total cost.

✅ GNT's Perspective: Systems Thinking Drives Market Leadership
These trends mark a turning point: the curtain wall and window industry is moving from fragmented supply models toward fully integrated system solutions. As a leader in steel profile development, GNT is committed to system-level thinking — optimising compatibility between frames, glazing, fire resistance, and hardware.

Looking ahead, we’ll continue collaborating with architects, façade contractors, and glass fabricators to elevate the global standard for steel curtain wall and window systems.
