Composite resin covers are made of high polymer composite materials and reinforced steel frames, formed through high-temperature molding, featuring excellent impact resistance, corrosion resistance, and anti-aging properties. They outperform similar products (such as cast iron, cement covers) in terms of technical performance and practicality, with reasonable product design and weight.

Lightweight, customizable, and free of recyclable value, the product fundamentally addresses the dangers posed by theft to pedestrians and vehicles, and is suitable for municipal drainage projects, urban road renovations, commercial street squares, garden landscapes, stadiums, industrial areas, residential communities, and more.
