Of course, its base material is glass fiber. You said it was rough, probably the reason wass that in the process of producing glass fiber, immature technology caused broken filament, and after treatment, the adhesive?sticker, alkali-resistant glue or weather-proof glue was unevenly attached on the surface. So it looks rough. This is just the unqualified product in production process, and there isn't any counterfeit product. These product are not beautiful and their strength will be lower than that of qualified products. (The intensity of different mesh will have different degrees of decline: generally, the largest mesh opening is, the greater will the strength decline; conversely, the smaller mesh opening is, the smaller will the strength decline).
