Import Bright Mirror Finished Surface 420j2 — Buy in Bulk from Supplier in China

The Bright Mirror Finished Surface 420J2 stainless steel coil from Taian Henson Metal Co., Ltd. is a martensitic grade coil strip engineered for applications requiring both surface reflectivity and mechanical wear resistance. 420J2 contains 0.26-0.35% carbon and 12-14% chromium, giving it a hardness range of HRC 50-55 after heat treatment, substantially harder than ferritic alternatives. The bright mirror finish on this coil achieves surface roughness values typically below 0.05 micrometres Ra, suitable for decorative and functional precision components. Taian Henson Metal offers this material with custom thickness and width dimensions to project requirements, though buyers should confirm exact dimensional tolerances and available coil weights directly with the supplier.

The 420J2 grade sits in the lower-carbon band of the 420 series, balancing hardenability with improved corrosion resistance over higher-carbon 420 variants. The bright mirror finish is produced through progressive polishing and buffing after cold rolling, not merely a passivation layer, so it contributes to corrosion protection while delivering aesthetic grade. Standard mill edge or slit edge options apply depending on downstream processing needs. Typical cold-rolled thickness for decorative coil applications ranges from 0.3 mm to 3.0 mm, with widths from 600 mm to 1500 mm, though Taian Henson's exact stock programme requires direct enquiry. The mirror surface demands protective interleaving film during coil handling to prevent abrasion marks in transit.

This material serves manufacturers of premium kitchenware, automotive trim, elevator panels, and architectural decorative elements where visual finish and scratch resistance coexist. Importers typically specify surface finish as 8K mirror or equivalent, with PVC film protection on one or both sides. Payment terms and Incoterms are not stated in the listing and must be negotiated with Taian Henson Metal directly. The supplier's response rate is currently zero percent, so buyers should allow extended time for quotation or consider alternative contact channels. Certificates of material compliance, mill test reports, and origin documentation should be requested before order confirmation.

Taian Henson Metal Co., Ltd. is based in China and operates as an imported-tier supplier within the harbour trust tier. The listing provides no information about the company's founding date, ownership structure, production capacity, or workforce size. Its response rate is recorded at 0.00% with an average response time of zero hours, indicating no recent engagement via the platform's inquiry system. Buyers should treat this as a signal to pursue direct contact through alternative channels rather than waiting for platform-mediated responses.

The supplier's profile, as presented, contains no verified certifications, no disclosed client references, and no stated annual revenue or export volume. The product offering centres on stainless steel coil in the 420J2 grade with decorative surface finishes. Buyers are advised to request a company profile, business licence, and quality management system certification directly. Third-party verification of mill capabilities, including whether Taian Henson operates its own cold-rolling and polishing lines or sources substrate from partner mills, would strengthen due diligence before committing to volume orders.
