AI-Powered supplier vetting

SummaryLaiwu Xincheng Metal Co., Ltd. is a China-based limited company in Shandong, identified as both a trading company and manufacturer/factory. It produces and exports steel products including round bars, square bars, slotted angle bars, cold-drawn bars, heat-treated bars, and threaded rods. The supplier reports multiple management-system certifications and operates more than 10 production lines, with stated output for several product categories. Its export activity is substantial by share of sales, began in 2018, and covers multiple global regions. Evidence also indicates a small R&D and quality-control workforce, a stated market-oriented innovation approach, and several buyer-linked trade records. However, the provided information does not sufficiently establish after-sales service processes, financial credibility, or proven customization performance.

Supplier typeThe supplier is explicitly identified as both a Trading Company and Manufacturer/Factory. Its business description states that it integrates research, design, development, manufacturing, and sales, indicating a combined manufacturing and trading model.

CertificationsThe supplier lists QHSE, OHSAS/OHSMS 18001, ISO 9000, ISO 14001, ISO 9001, and ASME certifications. These stated certifications provide explicit evidence of formal quality, environmental, occupational-safety, and sector-related management credentials.

Production capacityThe supplier reports operating more than 10 production lines and provides stated output for slotted angle bars, Q&T steel round bars, cold-drawn steel bars, and threaded rods. These explicit production-line and output records support meaningful manufacturing capacity.

Client casesThe supplier reports exports to more than 30 countries and regions, and trade records link it with buyers including METALLIED and FIT TIGHT FASTENERS LIMITED for alloy, cold-drawn, and hot-rolled steel bars. These records provide evidence of international customer activity, although the number of documented transactions is limited in the slices.

Product Q&A

Q:What are the available shapes for ASTM A36 cold drawn steel bars?

We supply round bars, square bars, hexagonal bars, and flat steel bars. Flat bars are available with either sharp edges or round edges.

Q:What is the size range for the cold drawn steel bars?

The size range varies by shape: Round bars from 3mm to 120mm, square bars from 3x3mm to 120x120mm, and hexagonal bars from 5mm to 120mm side to side.

Q:What are the main advantages of cold drawn steel bars over hot rolled ones?

Cold drawn bars offer tighter tolerances, smoother surfaces, better straightness for CNC feeding, and improved mechanical properties like yield and tensile strength.

Q:Which industries commonly use ASTM A36 cold drawn steel bars?

They are widely used in automotive, agriculture, construction, and motorcycle industries for parts like shafts, bearings, springs, and fasteners.

Q:What surface treatments are available for these steel bars?

The bars undergo cold drawing, turning, grinding, and polishing to achieve a bright, smooth surface with precise tolerances.
