For over three decades, Hebei Shunbo Metal Wire Mesh Manufacturing Co., Ltd. has engineered high-performance trench gratings that withstand the rigorous demands of industrial infrastructure, municipal drainage, and commercial construction projects worldwide. Our manufacturing heritage spans 30+ years of continuous innovation, establishing us as a trusted partner for engineers and procurement specialists seeking compliant, durable drainage solutions.
Engineering Excellence and ASTM Compliance
Our production facilities adhere to stringent international standards, manufacturing trench gratings that meet or exceed ASTM A123 and ASTM A53 specifications for material integrity and load-bearing capacity. Every grating undergoes precision hot-dip galvanizing processes, ensuring superior corrosion resistance and extended service life in harsh environmental conditions, from chemical processing plants to coastal marine applications.
Quality management systems at our Hebei facility maintain ISO 9001 certification, demonstrating our commitment to consistent manufacturing excellence. Additionally, our trench gratings carry CE marking, facilitating seamless integration into European infrastructure projects while satisfying North American regulatory requirements for public works and industrial installations.
Technical Specifications and Material Precision
We specialize in custom-engineered trench gratings fabricated from high-tensile steel and stainless steel alloys, designed to support load classes ranging from pedestrian traffic to heavy-duty H-20 and HS-25 highway loading. Our engineering team utilizes advanced CAD modeling and CNC cutting technologies to achieve dimensional tolerances within ±2mm, ensuring perfect alignment with precast concrete channels and cast-in-place drainage systems.

Global Distribution and Logistics Capabilities
Hebei Shunbo maintains robust supply chain networks facilitating efficient shipping to Canada, USA, and Europe, with dedicated export packaging protocols that prevent damage during ocean freight and overland transportation. Our logistics team manages customs documentation, including certificates of origin and mill test reports, ensuring compliant entry into destination countries.
Whether supplying standard 1-meter trench sections or custom-fabricated curved gratings for architectural applications, we coordinate multimodal shipping solutions that meet aggressive construction timelines. Our North American and European clients benefit from consolidated container programs and just-in-time delivery schedules that optimize inventory management for large-scale infrastructure developments.
Frequently Asked Questions
What load ratings do your trench gratings support?
Our standard product line accommodates load classes A15 through F900 per EN 1433 standards, equivalent to ANSI/SCTE load classifications. We engineer heavy-duty trench gratings specifically for airport runways, industrial forklift traffic, and municipal roadways requiring maximum structural integrity.
How does hot-dip galvanizing extend product lifespan?
Our galvanizing process applies zinc coatings averaging 80-100 microns thickness, providing 50+ years of corrosion protection in standard atmospheric conditions. This metallurgical protection exceeds painted or epoxy-coated alternatives, particularly in environments exposed to road salts, industrial chemicals, or UV degradation.
Do you provide custom fabrication services?
Yes. Beyond our standard inventory, we manufacture bespoke trench gratings with specialized bar spacing, non-standard widths, and integrated frames for unique drainage applications. Our engineering department provides shop drawings for client approval prior to production, ensuring exact specifications are met.
What certifications accompany international shipments?
All export orders include material certificates, ISO 9001 compliance documentation, and applicable CE marking declarations. We provide mill test reports verifying steel grade and tensile strength, alongside galvanizing thickness inspection reports for quality verification upon receipt.
