Every panel we ship is made to recognized international standards — ISO 9001 quality management, CE marking, ASTM A123 galvanizing, and ANSI/NAAMM MBG 531 fabrication tolerances — with mill certificates and inspection reports available on request.
Grating is a custom-order product. Because every panel is fabricated to project drawings rather than pulled from stock, the only meaningful guarantee a buyer has is the standard the factory builds to — and the paperwork that proves it. That is why GoGrating treats certification not as a marketing badge but as the backbone of how we quote, fabricate, and inspect steel grating and FRP grating.
Operating factory-direct from Anping, Hebei — the wire-mesh and grating capital that produces over 70% of China's output — we fabricate bearing bars from 20×3 mm up to 100×9 mm in 19-space and 15-space pitch series, with panel dimensions cut to order. Each specification is checked against the governing standard before production begins, and dimensional tolerances are verified before packing.
For EPC contractors, procurement engineers, and distributors, this means you can specify by standard reference on your purchase order — YB/T 4001.1, ANSI/NAAMM MBG 531, or your own project spec — and receive grating with traceable documentation behind it. See typical use cases on our applications page, or request a quote with your drawings.
ISO 9001 Quality Management System. Our fabrication facility operates under a certified ISO 9001 QMS covering incoming raw material inspection, in-process weld and dimension checks, and final inspection before dispatch. Material test certificates (MTCs) for bearing bar steel are retained and supplied with shipments on request.
CE Marking for European structural applications, supporting buyers in the EU who need conformity documentation for site handover. ASTM A123 governs our hot-dip galvanizing: coating thickness is measured and recorded per the standard's requirements, with untreated, painted, and stainless 304/316 finishes also available where the project demands them. ANSI/NAAMM MBG 531 and YB/T 4001.1 define the fabrication tolerances, bar spacing series, and banding details we build to — covering both North American-style and Chinese national specifications so your engineering team can reference whichever standard the project follows.
We do not publish generic load tables, because safe load capacity depends on bar size, span, and pitch for your specific configuration. Instead, we provide engineered load data referenced to ANSI/NAAMM MBG 531 for the exact specification you order. Send your drawings, CAD files, or a simple span-and-duty description via our request a quote form, and our engineers will respond with a compliant specification and supporting documentation.
Yes. Material test certificates for bearing bar steel, galvanizing coating-thickness reports per ASTM A123, and dimensional inspection records are available with every shipment. Tell us at the quoting stage which documents your project requires and we will include them in the export document package.
Either works. We fabricate to both, and the pitch series (19-space, 15-space) and bearing bar ranges (20×3 to 100×9 mm) map across the two standards. If your engineering drawings reference one standard, quote that on your RFQ and we will confirm the matching specification.
We do not publish generic load numbers, because capacity depends on bar size, span, and pitch. Once your specification is confirmed, we provide engineered load data referenced to ANSI/NAAMM MBG 531 for that exact configuration. Send your span and duty requirements with your quote request.
All grating is made to order — panel dimensions, bar size, pitch, surface treatment, and banding are cut to your drawings or CAD files. MOQ and lead time depend on the specification and finish; submit your project details through our request-a-quote form for a firm production schedule.
