Deepening Expertise in Retro Windows and Doors, Crafting Heritage Conservation Masterpieces

Since its establishment in 1998, Steel Lattice has dedicated itself to reviving the elegance of retro steel windows and doors, blending timeless aesthetics with modern engineering to meet the demands of heritage conservation projects. Rooted in Shanghai’s architectural legacy, Steel Lattice combines artisanal craftsmanship and advanced technology to deliver solutions that honor historical authenticity while ensuring durability and functionality

Retro steel windows and doors by Steel Lattice are renowned for their slim yet robust profiles, a hallmark of the brand’s commitment to precision. The use of thermal-dip galvanized steel guarantees rust resistance for over 30 years, a critical feature for preserving historical structures exposed to harsh climates

Unlike aluminum or wood, steel’s inherent strength allows for slender frames that evoke the delicate proportions of early 20th-century designs, making Steel Lattice a preferred choice for architects restoring landmarks like Shanghai’s Bund 18 and the Paramount Ballroom

Steel Lattice’s product portfolio includes the 32 Series and 40 Series retro steel windows, alongside proprietary innovations such as the 45 Series, 50 Series, and 65 Series aluminum-bridge imitation antique profiles. These offerings cater to diverse conservation needs, from replicating French-style casements to creating custom partitions that balance privacy and light diffusion

The brand’s retro steel windows and doors also integrate soundproofing, thermal insulation, and wind resistance, ensuring modern comfort within historic facades.A standout project exemplifying Steel Lattice’s expertise is the Huangpu District’s Waibanyuan 174 Block restoration. Adjacent to a 15-meter-deep excavation site, Steel Lattice implemented pre-reinforcement techniques—including temporary steel bracing and anchor-reinforced piles—to stabilize century-old buildings with倾斜 rates exceeding 4‰. This meticulous approach safeguarded structures like the Yuanmingyuan Apartments and the Lyceum Building, earning acclaim for harmonizing urban development with heritage preservation

Globally, Steel Lattice exports 20% of its retro steel windows and doors to the U.S., Japan, Australia, and Europe, underscoring its reputation as a leader in historical preservation projects. Recent accolades, such as contributions to Beijing’s Nanluoguxiang and Nanjing’s Confucius Temple, highlight Steel Lattice’s role in revitalizing cultural landmarks

Looking ahead, Steel Lattice remains committed to advancing retro steel windows and doors through R&D, aiming to set new benchmarks in material innovation and sustainable conservation. By merging tradition with cutting-edge technology, Steel Lattice continues to shape the future of heritage architecture—one meticulously crafted window at a time
