Steel Fabrication Delivery Workflow: From Design Review to Dispatch

Steel Fabrication Delivery Workflow: From Design Review to Dispatch

For a buyer, a steel fabrication order is not complete when the first cut is made. The real work is the controlled sequence that carries approved drawings through procurement, fabrication, inspection and dispatch. A clear workflow gives engineering, quality and logistics teams one shared view of what must happen before material leaves the shop.

At Kothari Chemicals (Engineering Division), the exact scope is agreed project by project. The sequence below is a practical framework for understanding the normal shop-to-dispatch flow.

1. Design Review and Production Planning

Before production planning starts, the team reviews the issued drawings, technical specification, approved quality plan and delivery requirements. This is where the project establishes the fabrication sequence, inspection points, material requirements and practical handling considerations.

Useful questions at this stage include:

• Which drawings and revisions are approved for production?
• What material grades, test certificates and traceability records are required?
• Which dimensions, welds or assemblies require hold points or third-party inspection?
• Is blasting, painting or metalizing included in the shop scope?
• What packing, loading and delivery constraints apply at the receiving site?

Resolving these questions early reduces rework later, particularly for large bridge and industrial members where changes after fit-up can affect both schedule and handling.

2. Material Procurement and Receipt

Material is procured against the approved specification. Where the project requires it, the receiving process is supported by material test certificates and identification records. The objective is straightforward: the material moving into fabrication should be traceable to the requirement it is intended to satisfy.

3. Fabrication Through the Planned Shop Flow

Cutting, drilling, fit-up, welding and straightening are arranged according to the production plan. The sequence changes with the component - a long bridge girder does not move through the shop in the same way as a smaller fabricated assembly - but the control principle remains the same: make each stage available for the required checks before the next irreversible operation.

4. Surface Preparation and Coating

If corrosion-protection work is included, surface preparation and coating are planned as part of delivery rather than treated as an afterthought. Kothari's facility includes automatic shot blasting, blast-room and paint-booth capability, with metalizing support for project-specific requirements.

The coating system, inspection criteria and final protection requirements should always be confirmed from the project specification.

5. Inspection and Release

Before a member is cleared for dispatch, the required dimensional checks, documented inspection and project-specific NDT are completed. Some specialist testing is coordinated through external support when the project scope calls for it. A release should be based on the agreed inspection plan - not on an assumption that the piece is ready because fabrication appears complete.

6. Packing, Loading and Dispatch

Final preparation protects both the fabricated member and the information attached to it. Identification, protection, packing and loading arrangements help the receiving team locate, handle and inspect the correct material safely. For long or heavy members, transport planning should be considered early enough to avoid a completed item waiting unnecessarily for a dispatch solution.

The Buyer Takeaway

A supplier should be able to explain who owns each stage, what information is released at that stage and what changes when the scope includes coating, testing or delivery to site. The shop drawing revision guide shows what to check when the drawing changes after material has been cut.
