Import Fabrication/Steel Structure Welding Product — Buy in Bulk from Supplier in China

This fabrication and steel structure welding product is manufactured from carbon steel grades Q235 and Q345, with wall thicknesses ranging from 3 mm to 12 mm and dimensional tolerances of ±0.5 mm, as specified in the source data. The components are precision-cut using CNC plasma and laser systems, then pre-assembled for field welding, ensuring minimal on-site adjustment. All parts are cleaned and deburred prior to shipment to reduce preparation time at the job site.

The base material complies with standard Chinese GB/T 700 and GB/T 1591 specifications for structural steel, with typical tensile strength between 370 MPa and 510 MPa. Surface preparation includes light blasting to achieve a Sa2.5 standard, though no coating is applied unless specified by the buyer. Typical weldability permits SMAW, GMAW, and FCAW processes, consistent with industry norms for structural applications. No alloying elements beyond manganese and silicon are present in the base composition, avoiding unnecessary cost and complexity.

These components are primarily used in industrial sheds, warehouse frameworks, and light-gauge bridge supports where structural integrity and repeatable fabrication are critical. Buyers include civil engineering contractors, prefabricated building manufacturers, and infrastructure maintenance firms in Southeast Asia and the Middle East. Trade terms are typically FOB Xiamen Port, with packaging in steel strapping and protective corner guards. MOQ and lead time must be confirmed directly with the supplier, as these vary by order size and component complexity.

Xiamen Yayu General Machinery Co., Ltd. is a machinery and structural fabrication supplier based in Jimei District, Xiamen, Fujian Province. The company operates from a registered industrial facility and is listed as an imported supplier with harbor-tier trust verification, indicating documented export activity and customs compliance. There is no public data on company size, revenue, or years in operation, and no certifications such as ISO or CE are confirmed in the source. Response rate and average response time are not available, suggesting limited buyer interaction or inactive customer service channels.

The supplier specializes in steel fabrication components for construction and industrial applications, with production focused on cut-to-size structural members and pre-assembled welding kits. No evidence exists of in-house welding certification, testing labs, or third-party inspection reports. The listing does not claim client names, project references, or export volume. Buyers should treat this as a direct manufacturer of fabricated parts without verified quality assurance systems beyond basic export readiness.
