Is your factory ISO certified?

Yes, our factory is ISO9001 certified. We can provide the certificate upon request.

Will the welding wire rust during shipping?

Our ER70S-6 wire has a copper coating for anti-rust protection. Under normal sea freight conditions, it will not rust within 3-6 months.

Do you support OEM / custom branding?

Yes, we can print your logo on the label and carton. Custom spool colors are also available for bulk orders.

What is your quality guarantee?

100% compliant with AWS A5.18 standard. We offer a 12-month quality warranty against manufacturing defects. If any quality issue arises, we will arrange replacement or refund after confirmation.

What welding positions can this wire handle?

All positions: flat, horizontal, vertical, and overhead.

What is the difference between ER70S-6 and ER70S-3?

ER70S-6 contains higher levels of silicon (Si) and manganese (Mn), providing better wetting and deoxidation, making it more suitable for rusty or dirty steel surfaces. ER70S-3 is used for clean, new steel.

AI-Powered supplier vetting

SummaryThe supplier is a Qingdao-based manufacturer and trading company with a broad registered business scope covering mechanical equipment, metal products, automotive parts, plastic products, building materials, and import/export activities. It reports ISO 9001, 14001, and 18001 certification history, eight production lines, 50 quality-control staff, and stated production capacity for several nail categories. The supplier offers customization from designs and samples, ODM, and OEM services for well-known brands. However, it reported no new products in the past year, lacks overseas warehouses, showrooms, agents, or branches, and has weak documented service-management controls: no written service-assessment or corrective-action procedures and no complaint-handling records. Financial information is identified for 2021–2023, but the slices do not provide performance values, so financial credibility cannot be fully assessed.

Supplier typeThe supplier operates as a manufacturer and trading company: its registered scope includes sales and import/export activities, while its factory information reports eight production lines and product-specific output. Its company description also states more than 20 years of development and business relationships across Europe, America, Southeast Asia, and Africa.

CertificationsThe supplier states that it passed ISO 9001, ISO 14001, and ISO 18001 international management-system certifications in 2001. This is explicit certification evidence, although the slice does not provide current certificate validity or renewal details.

After-Sales capabilityThe supplier has a complaint-handling procedure but no written complaint records, and it lacks written procedures or records for service-capability assessment and corrective/preventive actions. It has participated in the Canton Fair but reports no overseas warehouses, showrooms, agents, or branches, limiting evidence of structured overseas after-sales support.

R&D capabilityThe supplier reports ODM capability, an available SDK, and one internationally recognized design award. However, it also states that no new products were developed in the past year; this indicates some design and development resources but limited recent product-innovation evidence.

Production capacityThe supplier reports eight production lines, 50 quality-control staff, and stated annual outputs of 10,000 tons each for U-type, roofing, twisted, clout, and common nails. It also reports a one-month average lead time in both peak and off-season, supporting evidence of established production capacity, though the stated output figures are supplier-reported and not independently verified.

Customization capabilityThe supplier explicitly provides customization from customer designs and samples, ODM services, and OEM services for well-known brands. These statements directly demonstrate multiple forms of customization and contract-manufacturing capability.
