The LuZhongBao 12-inch round drain grate is a high-performance solution developed by Wuhan LuZhongBao Municipal Construction Support Facilities Co., Ltd., leveraging two decades of professional manufacturing experience for modern urban drainage systems. This product strictly complies with international drainage standards (e.g., EN1433) and the company’s internal quality control system (certified by ISO9001, ISO14001, SGS, etc.). It is specifically designed to collect surface rainwater and sewage while effectively filtering large debris to prevent pipe blockages. With a standard diameter of 12 inches (approximately 300 mm), it perfectly adapts to drainage gully interfaces of most municipal, commercial, and industrial buildings worldwide, serving as a reliable cornerstone for drainage networks around buildings, plazas, parking lots, and road edges.
The product uses high-strength ductile iron (QT500-7) or hot-dip galvanized steel as the core material, formed through precision casting to ensure the grate’s overall structure has no weak points. The surface is treated with eco-friendly coatings or hot-dip galvanizing technology, with salt spray resistance exceeding 2,000 hours, significantly extending its service life in humid, acidic, and alkaline environments. LuZhongBao deeply integrates functionality and durability, making this drain grate the first line of defense in keeping urban underground pipelines clear.
