quality Steel Curtain Wall & Fire Rated Curtain Wall factory

Published: May 13, 2025By GNT Marketing Team 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 LeadershipThese 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.

Published: May 13, 2025By GNT Marketing Team As architectural aesthetics evolve, steel curtain wall and window systems are gaining global popularity. Architects and developers now seek both structural performance and refined design. This article highlights the design-driven trends currently shaping the steel façade systems market.  Trend 1: Minimalist Design Fuels Demand for Large OpeningsWith a growing emphasis on visual transparency and spatial openness, slim frames and expansive openings have become standard in modern design. In high-end residential and commercial projects across Europe and North America, sliding doors, multi-track systems, and flush floor tracks are increasingly adopted to create seamless indoor-outdoor transitions. In regions with mild climates and scenic views, this aesthetic has become a hallmark of premium architecture. GNT notes that the demand for larger openings places higher requirements on structural strength, wind resistance, and sealing performance — areas where steel systems clearly outperform conventional alternatives. Trend 2: Growing Demand for Interior Steel Curtain Wall and Window ApplicationsSteel is no longer limited to exterior façades. Interior use is surging, with applications ranging from wine cellars and wardrobes to office partitions. Steel-framed doors and glass walls offer effective spatial separation without compromising natural light, delivering a sleek industrial-meets-modern look. Narrow steel profiles maximize transparency while maintaining distinct zones, offering greater flexibility and style in interior design. Trend 3: Energy Efficiency Now a Core Design PriorityAs sustainability becomes a key pillar of global construction, the steel curtain wall and window industry is embracing energy efficiency without compromising visual appeal. High-performance glazing, thermal break technologies, and insulating steel profiles are now standard in top-tier projects. At GNT, we’re committed to delivering systems that balance aesthetics, thermal performance, and structural integrity, helping clients meet strict energy codes while achieving architectural elegance.

Jiuling Lithium’s new Administrative and R&D Centre in Jiangxi Province represents a forward-thinking approach to sustainable industrial architecture. Covering more than 19,500 square meters, this flagship project aims to create an international business hub that consolidates Jiuling’s lithium carbonate production resources while showcasing a commitment to green, low-carbon development. To bring this vision to life, our company provided a comprehensive façade and interior solution that played a vital role in the project’s success. Our TBQ-T1 Thermal Break Curtain Wall System and TBQ-60G Hidden Frame Curtain Wall System were key in delivering superior thermal insulation, structural stability, and a clean, minimalist exterior appearance. The precision of our steel-framed systems, combined with the elegant blue-grey Low-E glass, ensured the building achieved outstanding energy efficiency and an exceptional architectural quality. In addition to the curtain wall systems, we supplied zinc-chromium alloy panel façades that were used extensively on terrace ceilings and exterior areas. These customizable panels brought a dynamic and flowing aesthetic to the building while maintaining durability and corrosion resistance — perfectly complementing the project's green and futuristic theme. For interior safety and functionality, our TBQ-B50 Fire-Rated Glass Partition and Door System was implemented throughout key areas. These systems not only enhanced fire safety standards but also maintained transparency and openness within the working spaces, aligning with the overall architectural vision of an airy, interconnected environment. By integrating our advanced products into the Jiuling Lithium project, we helped the client achieve their goals of reducing carbon emissions, improving energy efficiency, and creating a visually striking and internationally competitive facility.This collaboration stands as a testament to how innovative façade and fire protection systems can drive the success of next-generation green industrial buildings.

This project was finished in 2023, with 18,000 square meters.
