Infrastructure Polymer Drain Strainer with Frame

The BAOGAI Advantage: Corporate Trust & Precision Engineering

In the world of civil engineering, the “cheapest” component is often the most expensive to replace. BAOGAI provides a high-performance investment.

• The Industry’s Only Publicly Listed Company:

As the only publicly listed corporation in China’s composite infrastructure sector, BAOGAI provides unparalleled transparency and financial stability. For international municipal departments and EPC contractors, this is a “seal of trust” ensuring that every batch meets rigorous ISO quality standards and project timelines.

• Direct In-house Mold Center:

These specific sizes (215x295x90, 185x265x20) require a perfect “grating-to-frame” seat to prevent noise and displacement. Because we operate our own mold factory, we better guarantee product quality and dimensional accuracy. We can also provide Rapid OEM Customization—embossing your municipal logo or specific utility markings with elite precision.

Product Overview

The BAOGAI Composite Grating Series is engineered for high-frequency drainage in residential, commercial, and municipal zones. Unlike traditional brittle cast iron, our composite formula is designed to withstand heavy impacts and high-axle loads without cracking or corroding.

The 215x295x90, 185x265x20 mm specification features a deep 90mm frame for maximum anchorage in concrete, making it ideal for curbside drainage on busy streets. This version is a slim-profile solution perfect for shallow-set drainage in walkways and plazas. Both models feature an aggressive anti-slip mesh that maximizes water intake while ensuring pedestrian and cyclist safety.

MAIN PARAMETER

Core Benefits for Municipal Infrastructure

1.Permanent Anti-Theft Protection:

Composite gratings have zero metallic scrap value. This eliminates the primary motive for theft, keeping your roads safe and protecting the city from the liability and cost of open drainage pits.

2.Corrosion & Salt Immunity:

Perfect for coastal regions and winter climates. Unlike iron, these gratings will never rust or seize into their frames when exposed to road salts or chemical runoff.

3.Silent & Precision Fit:

Leveraging our in-house mold precision, the grating-to-frame tolerance is minimal. This eliminates the “metal clanging” noise when vehicles drive over, ensuring a quieter urban environment.

4.Exceptional Durability:

The material is fatigue-resistant and UV-stabilized. It maintains its structural integrity and load-bearing capacity for 30–50 years, even under intense sunlight and heavy traffic.

5.Cost-Effective Logistics:

Significantly lighter than solid iron counterparts, allowing for higher container loading volumes and reduced labor intensity during installation.

FAQ

Q1: Why choose a 90mm frame for the 215 x 295 model?

A: The 90mm depth is designed for heavy-traffic curb zones. It provides a deep mechanical bond with the asphalt or concrete bed, ensuring the grating remains stable under high-speed vehicular impact.

Q2: How does your status as a “Listed Company” benefit my order?

A: It guarantees accountability. We use high-grade resins and fibers. Because we are subject to rigorous public audits, we cannot compromise on raw material quality—giving you peace of mind that the product matches the technical datasheet.

Q3: Can we add our custom project logo on the grating?

A: Absolutely. Our in-house mold factory allows us to create custom-embossed gratings with your municipal logo or text (e.g., “DRAINAGE”, “STORM WATER”) with much faster lead times than our competitors.
