Project Overview

ZSJH has completed steel fabrication work for the JD Logistics warehouse project in Beijing, China. The project photographs document workshop fabrication, connection assembly, weld inspection and component dispatch. The fabrication record follows the details that connect workshop production with on-site assembly.

The photographed components include large tubular steel members, ring-shaped plates, stiffeners and connection plates with grouped bolt holes. They illustrate the fabrication work behind a logistics warehouse project, where member geometry and connection interfaces need careful coordination.

Large Tubular Members

Long tubular members are shown supported on workshop equipment during fabrication. Other photographs record circumferential welds between tube sections. For components of this type, alignment, fit-up and weld preparation are important manufacturing considerations: a small deviation at one stage can affect the position of a connection farther along the member.

The workshop views provide a practical reference for buyers evaluating a supplier’s ability to handle tubular steelwork and project-specific assemblies. They show intermediate production stages, including bare steel surfaces before subsequent finishing operations.

Detailed Connection Assemblies

The connection photographs show tubular members combined with ring plates, stiffeners and projecting plates containing multiple bolt holes. These are substantial assemblies rather than isolated pieces of steel. Plate orientation, hole-group positioning and access for welding all require attention during fabrication.

Close-up views make these interfaces visible. For warehouse steelwork, clear connection details help coordinate shop assembly with the components that will meet on site. The photographs also distinguish individual connection subassemblies from the larger tubular members into which they are incorporated.

Project Inspection and Delivery

Weld Inspection and Dispatch

One project photograph records an inspector using a portable ultrasonic instrument at a circumferential tube weld. It provides a direct view of an inspection activity during production. The inspection view highlights attention to weld quality during component production.

The dispatch photograph shows fabricated steel components stacked on a truck with spacers and supporting arrangements. Connecting component identification, shipment lists and site receiving plans is an important part of moving fabricated steel from the workshop into the next construction stage.
