Industrial drainage infrastructure requires components that withstand extreme loads, corrosive environments, and constant mechanical stress. Hebei Shunbo Metal Wire Mesh Manufacturing Co., Ltd. delivers precision-engineered drain frame solutions designed for municipal, commercial, and heavy industrial applications where failure is not an option.
Three Decades of Manufacturing Excellence
With over 30 years of specialized production experience, Hebei Shunbo has established itself as a leading manufacturer of metal mesh and drainage components. Our manufacturing facilities in Hebei Province utilize advanced CNC cutting, robotic welding, and automated galvanizing lines to produce drain frame units that meet the most demanding specifications. This extensive operational history enables us to anticipate field challenges and engineer proactive solutions into every product design.
Engineering Standards and Material Specifications
Our drain frame manufacturing adheres strictly to ASTM A123/A123M standards for hot-dip galvanizing, ensuring superior corrosion resistance in harsh environments. We employ high-grade carbon steel and stainless steel alloys, with zinc coating thicknesses exceeding 600g/m² for extended service life in coastal or chemically aggressive installations. Each frame undergoes dimensional verification using CMM (Coordinate Measuring Machine) technology, maintaining tolerances within ±0.5mm for seamless integration with grating panels and channel systems.
Technical specifications include load ratings from A15 to F900 (EN 1433 compliance), custom frame dimensions ranging from 300mm to 1200mm standard widths, welding per AWS D1.1 structural welding codes, and surface treatments including hot-dip galvanizing, epoxy coating, or stainless steel passivation.
Global Certifications and Quality Assurance
Hebei Shunbo maintains ISO 9001:2015 certification for quality management systems, ensuring consistent production standards across all drain frame batches. Our products carry CE marking for European Economic Area compliance, meeting EN 1433 and EN 124 standards for drainage channel systems and manhole covers. These certifications demonstrate our commitment to international safety and performance benchmarks, supported by comprehensive material test reports and mill certificates for full traceability. For detailed compliance documentation, refer to our technical specifications repository.
Applications Across Critical Infrastructure
Our drain frame systems serve diverse sectors including airport runways, port facilities, petrochemical plants, and municipal roadways. The modular design accommodates various grating types—bar grating, mesh grating, and ductile iron covers—providing flexibility for hydraulic engineers and civil contractors. Frames feature pre-drilled anchor points and leveling systems that simplify installation while preventing displacement under dynamic loading conditions.
International Logistics and Customer Support
We maintain established export protocols for North American and European markets, with regular shipments to Canada, the United States, Germany, France, and the United Kingdom. Our packaging systems utilize moisture-barrier VCI film and reinforced wooden crates to prevent transit damage and corrosion during ocean freight. Documentation includes commercial invoices, packing lists, certificates of origin, and bill of lading instructions formatted for customs clearance in destination countries.
Professional FAQ
What load classes are available for your drain frame systems?
We manufacture frames ranging from Class A15 (pedestrian areas) to Class F900 (airport runways and docks), with intermediate options for commercial parking (B125) and highways (D400). Each class undergoes specific proof load testing before release.
Can you produce custom dimensions for specialized drainage channels?
Yes, our engineering team provides OEM and ODM services for non-standard widths, depths, and edge profiles. Custom drain frame units require 15-20 working days for prototype approval and 25-30 days for production batches.
What is the expected service life of hot-dip galvanized drain frames?
In typical urban environments, properly maintained galvanized steel frames last 25-30 years. Marine or industrial chemical environments may require stainless steel 304 or 316L alternatives, which we also supply.
Do you provide installation hardware and technical support?
Each drain frame shipment includes galvanized anchor bolts, leveling shims, and installation guidelines. Our technical department offers video consultation for complex installations and can provide shop drawings stamped by licensed engineers for permit applications.
What is your minimum order quantity for international shipping?
Standard container loads (20′ or 40′ FCL) offer optimal freight economics, but we accommodate LCL (Less than Container Load) shipments for urgent projects. Mixed product containers combining drain frames with grating panels maximize shipping efficiency.
