Heavy-Duty Municipal Catch Basin Grate

The BAOGAI Advantage: Corporate Trust & Precision Engineering

In high-traffic municipal projects, the reliability of the manufacturer is the ultimate insurance for public safety.

• 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 & Tooling Factory:

Manufacturing a 350 x 600 mm grating without a frame requires perfect dimensional consistency to ensure it fits existing trenches. Because we operate our own mold factory, we maintain micron-level precision. This also allows us to offer Elite OEM Customization—integrating specific patterns, logos, or high-visibility colors with faster delivery and direct factory pricing.

Product Overview

The BAOGAI 350x600x40mm FRP Drainage Grating is a lightweight, corrosion-proof access solution designed for direct installation into drainage channels, trenches, and pits. Featuring a frameless design, it installs directly into pre-formed channel recesses without the need for separate frames—reducing installation time and material costs. Constructed from high-strength Fiber Reinforced Plastic (FRP), it delivers exceptional corrosion resistance, high strength-to-weight ratio, and zero theft value, making it ideal for municipal, industrial, and commercial drainage applications.

Core Benefits of BAOGAI FRP Gratings

1.Permanent Anti-Theft Security:

FRP has zero scrap value, effectively eliminating the motive for theft. This protects municipal budgets and, more importantly, prevents the serious public safety hazard of open drainage pits on busy roads.

2.Superior Corrosion Resistance:

Completely immune to road salts, automotive chemicals, and acid rain. Unlike ductile iron, BAOGAI FRP gratings will never rust or “seize,” ensuring easy access for cleaning and maintenance for over $30$ years.

3.High Strength-to-Weight Ratio:

At 40mm thick, this grating matches the load-bearing performance of iron but is significantly lighter. This reduces labor intensity during installation and drastically lowers international shipping costs.

4.Quiet & Vibration-Dampening:

The composite material naturally absorbs impact and vibration. When installed correctly, it eliminates the “metal clanging” noise common with iron grates, leading to quieter urban and residential environments.

5.UV Stable & Weatherproof:

Our formula is enriched with high-grade UV stabilizers, ensuring the grating maintains its structural integrity and color even in extreme sunlight or freezing temperatures.

Target Applications

• Urban Roadways & Sidewalks: Rapid storm-water drainage for city streets.
• Parking Lots & Commercial Plazas: Aesthetic and durable drainage for high-footfall areas.
• Industrial & Chemical Plants: Rust-proof drainage for corrosive environments.
• Coastal Infrastructure: Salt-spray resistant solutions for ports and beachfronts.

FAQ

Q1: Will this 350x600mm grating fit my existing concrete trench?

A: Yes. Because we control our in-house mold factory, we ensure strict dimensional accuracy. As long as your trench rebate matches these dimensions, our grating will provide a flush, secure fit. We can also provide technical drawings for verification.

Q2: How does your “Listed Company” status benefit my procurement?

A: It guarantees accountability. We use high-grade resins and glass fibers. Unlike small private workshops that might use inferior fillers, we are audited for quality to protect our corporate reputation and your infrastructure safety.

Q3: Is the “No Frame” design safe for heavy traffic?

A: Absolutely, provided the concrete rebate is structurally sound. For D400 highway applications, we ensure the reinforcement of the FRP is optimized to handle high-frequency impact loads.

Q4: Can we customize the grating color for a safety zone?

A: Yes. We can produce the gratings in safety yellow, green, or other colors to designate specific utility zones or improve visibility in low-light industrial areas.
