In many outdoor projects, one of the most frequent customer complaints is that while the sheets are initially very transparent, they begin to yellow and even become brittle after a period of use.

In recent years, polycarbonate sheets have become increasingly common in shopping mall corridors, park passageways, carports, and skylights. Many customers, upon first encountering this material, often offer a straightforward assessment: it's cheaper than glass, hence its widespread use. However, attributing this solely to "cheapness" underestimates the value of polycarbonate sheets in engineering projects.

In actual engineering communication, "thickness" is almost always one of the first questions clients ask. However, this seemingly simple question is often the most easily misunderstood. Many people instinctively believe that thicker is safer and more durable. But in real projects, this approach can actually lead to wasted costs and even affect structural design. Thickness is never a parameter in isolation; it corresponds to the load-bearing structure, installation method, and usage scenario. Discussing thickness without considering these factors easily leads to choosing the wrong direction from the outset.

In traditional architecture and municipal engineering, glass has always been the mainstream material for lighting, fencing, and sound barriers. However, in recent years, a very obvious trend has emerged—more and more projects are starting to replace glass with polycarbonate solid sheets. Many clients ask during consultations, "Why is glass being used less in engineering projects now?" The answer isn't simple; rather, it's because as engineering standards improve, the core logic of material selection has changed: from "usable" to "safer, more efficient, and more durable."
