Find drawing issues while they can still be resolved on paper. ZSJH reviews steel fabrication drawings from the workshop execution perspective, checking dimensions, part relationships, welding access, bolting space and issue consistency. The result is a prioritized comment and clarification package to support controlled release for production.

Item | Project Scope |
Input package | Current shop drawings, drawing register and approved references |
Review coverage | Agreed members, assemblies and interfaces |
Dimensional review | Datums, closing dimensions, holes and end orientation |
Process review | Cutting, drilling, assembly and welding access |
Comment records | Drawing reference, priority, owner and response status |
Deliverables | Marked-up PDFs, RFI list and closure register |
Authority | Manufacturing review; design changes require designer approval |
Release status | Open items and approval conditions stated explicitly |
Reviewers can draw on the same cutting, drilling, welding and assembly activities used in steel production. They examine how a welder reaches a joint, how a bolt is tightened and how an assembly is positioned. Practical comments are returned with a drawing reference so the detailer can respond precisely.

Use before releasing first-article assemblies, imported detailing packages, complex welded members or revised drawings. It is particularly useful when a design team and overseas fabrication shop work from different document systems.
Separate drafting discrepancies, manufacturing constraints and design queries. Record the response to each comment and confirm that the accepted change appears in the issued revision. Only authorized personnel release production documents; this service does not replace independent structural design checks.
The review package is digitally delivered with a closure register for international teams. For ZSJH export orders, agreed comments feed the production issue, inspection references and component identification. Revised parts are reconciled before packing so shipment records reflect the authorized manufacturing scope.

Q1:Does a review automatically authorize fabrication?
A1:No. Release depends on the project approval workflow and closure of relevant comments.
Q2:Can you review a changed drawing after cutting has started?
A2:Yes, if the current production status is provided. The review must also identify affected material and completed work.
Provide the current drawing register, shop drawing package, design references and planned production date. Flag any members already cut or assembled so the review can address the actual release risk.
