Project Overview
At Zhongbo Glass, we take special pride in projects that elevate our home province of Henan. The Baoquan Xiangyun Viewing Platform in Xinxiang is one such project — a breathtaking cantilevered glass platform that extends over the stunning Baoquan landscape, offering visitors the sensation of floating above the valley. As a local manufacturer, we were honored to be entrusted with the glass floor panels that make this heart-racing experience possible.
The viewing platform demanded glass that could withstand heavy visitor traffic, harsh outdoor conditions, and the psychological weight of looking straight down from a dizzying height. We delivered ultra-clear, triple-ply SentryGlas® Plus (SGP) laminated glass panels that provide absolute structural safety without sacrificing one bit of the spectacular view. For Zhongbo Glass, the Baoquan Xiangyun Viewing Platform is not just another project — it is a landmark in our own backyard and a powerful demonstration of how we serve world-class attractions right here in Henan.
Glass Configuration — Compact, Strong, and Crystal Clear
For the platform’s transparent floor, we fabricated a triple-ply laminate engineered for pedestrian loading, impact resistance, and optical perfection:
12mm Ultra-Clear Tempered + 1.78mm SentryGlas® Plus (SGP) + 12mm Ultra-Clear Tempered + 1.78mm SGP + 12mm Ultra-Clear Tempered — Fully Laminated
This configuration packs immense strength into a sleek profile:
-
Three 12mm Ultra-Clear Tempered Plies: All three plies are premium low-iron glass, fully tempered to a surface compression exceeding 69 MPa. This provides four to five times the strength of ordinary annealed glass per layer. The ultra-clear composition eliminates any greenish tint, ensuring the valley below appears in vivid, natural color.
-
Dual 1.78mm SGP Interlayers: Two layers of SentryGlas® Plus ionoplast interlayer bond the glass into a monolithic structural composite. SGP offers five times the tear strength and far greater stiffness than conventional PVB. In the extremely unlikely event of all glass plies breaking, the SGP interlayers keep the entire panel intact and rigid, preventing any risk of a visitor falling through.
-
Total Thickness Exceeds 39mm: With 36mm of glass and 3.56mm of SGP, each panel is a dense, load-bearing slab that comfortably supports the weight of multiple visitors with generous safety margins.
-
Monolithic Safety: The fully laminated design ensures that the viewing platform remains a secure walking surface under all conditions, meeting the strictest safety standards for public attractions.
Maximum Glass Size: 1,800mm × 2,200mm — Precision Panels for a Precision Platform
The maximum glass panel size for the viewing platform was 1,800mm in width by 2,200mm in length — covering nearly 4 square meters per panel. While these dimensions are moderate compared to our record-breaking bridge panels, the application is equally critical. Each panel is a self-contained section of the transparent floor, and every single one must perform flawlessly. The cantilevered platform design means these panels bear the full weight of visitors with nothing but air beneath them.
At Zhongbo Glass, we approach every structural glass project — regardless of panel size — with the same exacting quality standards. The panels for Baoquan received the same rigorous tempering, cleanroom lamination, and edge finishing as our largest bridge glass.
Overcoming the Challenges — Local Manufacturing, World-Class Quality
1. Perfect Tempering for Uniform Flatness and Strength
Tempering 12mm ultra-clear glass requires precise thermal control to avoid roller-wave distortion and ensure uniform surface stress. Our jumbo flat tempering furnace, programmed with proprietary recipes for low-iron glass, produced all three plies per panel with consistent flatness and full temper strength. For a viewing platform, any optical distortion is unacceptable — visitors demand a perfectly clear view down. We delivered.
2. Triple-Ply SGP Lamination for Life-Safety Applications
Laminating three 12mm plies with SGP interlayers, even at moderate sizes, is a process where there is zero tolerance for defects. We followed our proven structural glass protocol:
-
Class 1 cleanroom layup to ensure no dust or contamination between plies.
-
Vacuum bag de-airing tailored for thick SGP stacks, removing all trapped air.
-
Custom autoclave cycle in our high-pressure autoclave, fully bonding the entire panel into a bubble-free, crystal-clear laminate with edge-to-edge SGP adhesion.
Every finished panel was inspected for optical clarity, bond integrity, and dimensional accuracy before leaving our factory.
3. Edge Quality for Outdoor Durability
The viewing platform is exposed to the elements year-round — rain, sun, and temperature swings typical of Henan’s climate. We precision-ground and polished all panel edges to remove any micro-cracks, then ensured the edges would be fully protected within the platform’s framing system. Combined with SGP’s inherent resistance to moisture ingress, these panels are built for a long outdoor service life.
4. Local Logistics Advantage
Being located in Henan, we provided superior logistics support for the Baoquan project. Our proximity to Xinxiang meant shorter transport distances, reduced handling risk, and the ability to offer rapid on-site support. We delivered every panel in custom protective stillages, with our own team coordinating directly with the installation crew. This local advantage ensures that our clients in Henan receive not just world-class glass, but world-class service — faster and with greater reliability.
