Import Composite W-Smc Water Grate — Buy in Bulk from Supplier in China

The Composite W‑SMC water grate offered by Hangzhou Jinmeng Road Facility Co., Ltd. is moulded from high‑strength W‑SMC sheet‑moulding plastic. It achieves a maximum static load of 900 kN, meeting the GB/T23858‑2009 standard for manhole covers. The grate’s appearance mimics iron plates while providing a non‑metallic composition that resists corrosion. The product’s anti‑theft design eliminates any recyclable metal value, reducing theft risk.

Typical thickness for this class of grate is around 30 mm, giving sufficient rigidity for heavy traffic. Standard size modules range from 400 mm × 400 mm up to 800 mm × 800 mm, and colour options include gray, black and green for visual integration. Compared with cast‑iron equivalents, the W‑SMC grate is roughly 40 % lighter, simplifying handling and installation. The material tolerates temperatures from - 30 °C to 80 °C without degradation, a typical performance envelope for composite infrastructure components.

Municipal utilities, telecom providers and contractors for highways, airports and industrial plants commonly specify this grate for inspection wells and drainage channels. The supplier can customise dimensions and load ratings according to project requirements, though exact specifications must be confirmed per order. Procurement is usually arranged in palletised bundles, with the buyer responsible for confirming MOQ, Incoterms and any required quality certifications.

Hangzhou Jinmeng Road Facility Co., Ltd. operates from Fangyuan Industrial Park, Yuqian Town, Lin’an, Zhejiang Province, China, postal code 311311. The supplier carries a harbour‑level trust tier, and its platform metrics show a 0 percent response rate with no average response time recorded. These indicators mean enquiries may require follow‑up reminders.

Since 2009 the company has developed and patented high‑strength W‑SMC sheet‑moulding plastic products, including the water grate described in the listing. The catalogue highlights anti‑theft properties, lightweight construction and compliance with GB/T23858‑2009, but the supplier does not list specific certifications or third‑party test results. Prospective importers should ask for the patent documentation and any relevant material test reports.
