Key features

Premium Centrifugal Casting: Manufactured via advanced centrifugal casting using low-Si, ultra-low carbon 316L/317L or superalloys for zero thermal deformation at 480 degree centigrade

HVOF Cermet Coating: Shielded with state-of-the-art HVOF tungsten carbide (WC-Co-Cr) coating, reaching a surface hardness over HV1000 to drastically minimize zinc dross pick-up.

Precision Groove Engineering: Available with custom spiral, herringbone, or straight grooves to ensure rapid liquid zinc drainage and smooth strip tracking without scratching.

ISO G2.5 Dynamic Balance: 100% dynamically balanced to ISO 1940 Grade G2.5/G1.0 standards to eliminate high-speed vibration and guarantee steady strip tension.

Heavy-Duty Wear Protection: Roll journals are reinforced with specialized Stellite alloy cladding or integrated ceramic sleeves to ensure maximum wear resistance against arm bushings.

AI-Powered supplier vetting

SummaryShijiazhuang Huatao Import and Export Trade Co., Ltd. is a China-based limited trading company established in 2008 with 12 employees. It identifies as a professional technical supplier and offers 3D software design, ODM, and multiple customization options. However, the evidence indicates limited innovation activity, with one R&D engineer and no new products launched in the previous year. The supplier has no stated inventory, overseas warehouse, showroom, agent, or branch capability. After-sales procedures exist for service assessment, corrective actions, and complaints, but no written records were provided. The supplier has participated in an overseas trade show and reports service offerings in France, including installation, maintenance, repair, debugging, and training. No certification information, financial assessment evidence, production capability, or sufficiently detailed customer-case evidence is provided.

Supplier typeThe supplier is explicitly classified as a trading company and limited company, operating in wholesale and retail. Its profile indicates an intermediary/trading role rather than a documented manufacturing enterprise.

After-Sales capabilityThe supplier reports overseas debugging, maintenance, repair, training, and equipment installation services in France, and has procedures for service assessment, corrective actions, and complaint handling. However, the procedures have no written records, and the supplier has no overseas warehouse, showroom, agent, or branch, limiting the strength of the documented service infrastructure.

R&D capabilityThe supplier has one R&D engineer and provides 3D design and ODM services, but it launched no new products in the previous year and has no SDK available. This combination demonstrates some design capability but does not establish strong recent innovation performance.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, together with 3D software design and ODM services. These statements directly support a broad customization capability.

Product Q&A

Q:What base materials and coatings do you use for your zinc pot rolls / sink rolls?

Our base rolls are primarily manufactured via centrifugal casting using premium ultra-low carbon stainless steel (316L, 317L, 1.4404) or customized nickel/cobalt-based superalloys. For the surface, we apply high-density WC-Co-Cr (Tungsten Carbide) or Mo-B (Molybdenum Boride) coatings using advanced HVOF (High-Velocity Oxygen-Fuel) thermal spraying to ensure maximum anti-dross performance.

Q:Can you manufacture sink rolls and stabilizer rolls according to our specific blueprints?

Yes, absolutely. We offer full OEM/ODM customization services. Over 90% of our metallurgical rollers are tailor-made based on the specific engineering drawings, technical dimensions, line speeds, and tension parameters provided by our global steel mill clients.

Q:What is the typical campaign life of your sink rolls in a hot-dip galvanizing line?

The actual service life depends heavily on your steel grade requirements, line speed, and bath chemistry. For standard construction steel lines, our rolls can serve reliably for 20 to 30 days continuously. For high-end automotive exposed panel lines (GI/GA), they generally undergo scheduled maintenance every 7 to 14 days to ensure zero surface defects. The base roll itself can be re-machined and re-coated 10 to 20 times.

Q:How do you guarantee the quality and dynamic balance of the rolls before shipment?

We enforce a strict zero-defect policy. Every roll undergoes 100% Non-Destructive Testing (NDT) including Ultrasonic Testing (UT) and Dye Penetrant Testing (PT) on all welds and surfaces. We also provide a comprehensive quality tracing package with every shipment, which includes Spectrochemical Material Reports, Coating Micro-Hardness and Thickness Reports, and a certified ISO 1940 Dynamic Balancing Report.

Q:What is your minimum order quantity (MOQ) and typical delivery lead time?

Our MOQ is 1 piece. The production lead time generally ranges from 30 to 45 days upon drawing approval and deposit receipt, depending on the roll dimensions, material specification, and our current workshop casting schedule.
