How We Realized the Glowing Facade of Shijiazhuang City Exhibition Center: A Translucent Concrete Installation Guide

The "Light of the City": Beyond Traditional Masonry Walking past the Shijiazhuang City Exhibition Center at night, you aren't just looking at a wall; you're looking at an engineering marvel. Many customers ask us: "Is it a screen? Is it glass?" No, it’s Translucent Concrete.

As a team with 15 years in thermal and specialty materials, we’ve seen how this "living stone" transforms a cold structure into a warm, glowing landmark. Here is the "down-to-earth" breakdown of how it's done:

Step 1: The Backlight Cavity (The "Lungs" of the Wall) You can’t just slap LED strips behind the panels. At the Shijiazhuang project, we maintained a 120mm to 150mm cavity. Why? Because light needs space to diffuse. If the light is too close, you get ugly "hot spots." If it’s too far, the glow is weak.

• Pro Tip: Always use 3000K warm-white LEDs to get that premium, golden-hour look shown in our project photos.

Step 2: Precision Dry-Hanging (Strength Meets Art) Each panel is heavy, similar to natural stone. We use a stainless steel back-bolt system. Unlike traditional wet-pasting, dry-hanging allows for thermal expansion and contraction.

• The Secret: The fiber optic points must align perfectly. Even a 2mm tilt can ruin the visual flow of the light pattern.

Step 3: Sealing and Weatherproofing Outdoor landmarks face rain, dust, and UV. We treat the surface with a fluorocarbon penetrating sealer. This keeps the "pores" of the fibers clean so the light stays crisp for decades, not months.

Why Woqin? We don't just ship crates of concrete. We provide the technical backup that most trading companies can't. Whether it's custom patterns or on-site installation consulting, we help you reduce procurement friction.
