Import 304 316 5mm 10mm Stainless Steel Round Bar — Buy in wholesale FOB from Supplier in China

This stainless steel round bar from Shaanxi Z.s.b. Metal Product Co., Ltd. is offered in austenitic grades 304 and 316, with quoted diameters of 5 mm and 10 mm. The material is cold rolled and polished, conforming to ASTM, AISI, EN, JIS, GB, and DIN standards according to the supplier's description. Grade 316 provides enhanced resistance to chloride-induced pitting and crevice corrosion compared with 304, making it preferable for marine, chemical, and coastal architectural environments. The supplier lists ISO and RoHS certifications on the profile, though buyers should request current validity and scope details directly.

Cold rolled round bar achieves closer dimensional tolerances and superior surface finish over hot rolled or extruded alternatives. The 5 mm and 10 mm diameters sit within the precision bar segment, where h9 or h11 tolerance classes are common depending on application requirements. Grade 316 typically contains 16 - 18% chromium, 10 - 14% nickel, and 2 - 3% molybdenum, with molybdenum content being the key differentiator from 304. The polished surface treatment removes oxide scale and reduces surface roughness, which benefits hygiene-critical applications in food and pharmaceutical equipment. Standard straightness for cold finished bar is typically 1 mm per metre, though the supplier does not specify this parameter.

Buyers span machinery shafts, valve stems, marine hardware, chemical pump components, and architectural balustrading. The 5 mm size suits smaller turned components and fixings, while 10 mm serves medium-strength structural and functional parts. Shaanxi Z.s.b. states flexible minimum order quantities and export-ready packaging, but no specific MOQ, lead time, or price band is published. Prospective importers should confirm whether bars are supplied in random lengths, fixed lengths, or on spools, and verify that the supplier's quality system covers the specific diameter and grade combination required.

Shaanxi Z.s.b. Metal Product Co., Ltd. operates from No 18, Tang Yan Road North, Xi'an, Shaanxi Province, China. The company holds a harbour trust tier, representing an entry-level verification status on the marketplace. The profile displays a 0.00% response rate with no average response time recorded, which signals that buyers should initiate contact proactively rather than expecting rapid automated feedback. No information about factory ownership, production capacity, workforce, or years in operation is provided in the available profile data.

The listing presents the company as a source of stainless steel bars across 304 and 316 grades, with emphasis on cold rolled and polished round bar in 5 mm and 10 mm diameters. The profile does not disclose whether manufacturing occurs at the Xi'an address or whether the company functions as wholesalers, traders, or manufacturers. Buyers are advised to request business registration documents, ISO 9001 certificate copies, and recent customer references before placing significant orders. Given the lack of response metrics, consider a small trial order to assess product quality, packaging standards, and documentation accuracy before scaling volume commitments.
