From RFQ to Repeat Order: A Sheet Metal Fabrication Case Study for Australian OEM

Aug 09, 2026 Leave a message

Every repeat order starts somewhere. For one Australian industrial equipment OEM, it started with a frustrated email and a stack of rejected parts.

 

They had been sourcing a family of sheet metal brackets and welded frames from a low-cost supplier for nearly two years. The unit price looked great on paper, but the hidden costs were eating the program alive: inconsistent bend angles, slots that did not line up during assembly, and surface finish issues that caused problems after hot-dip galvanizing. By the time we received the RFQ, they were actively looking for a fabrication partner who could stabilize the program without blowing the budget.

The Real Problem Was Not the Drawing

The customer's drawings were solid. The issue was process control. Their previous supplier was treating the parts as generic sheet metal blanks instead of matching a welding-and-assembly system. Small dimensional drift accumulated: laser cutting kerf variation turned into fit-up gaps, manual tacking introduced distortion, and final welds were being dressed by hand without a consistent standard. When the parts reached the galvanizer, those inconsistencies became visible as uneven coating thickness and rework.

We proposed a different approach.

What We Changed on the Shop Floor

Laser Cutting: Brought every critical dimension onto our 6kW fiber laser cutting workflow and cut the first article from the exact production nest - establishing a dimensional baseline before any tooling touched the part.

Welding Fixtures: Built simple but rigid fixtures for the repeated frames so each assembly was tacked and welded in the same clamped position, eliminating distortion drift between batches.

Inspection: Wrote an AWS D1.1 visual inspection directly into the production traveler - not as an afterthought, but as a mandatory gate before parts moved to galvanizing.

Galvanizing: Coordinated parts directly with an AS/NZS 4680 HDG hot-dip galvanizing line, optimizing venting and drain holes so the coating came back uniform and free of excessive zinc buildup in corners.

The Results After Six Months

First article approved on the second submission - the only change was a minor packaging note.

Measurable drop in rework hours on the customer's assembly line.

Fewer urgent air-freight requests to catch up on delayed batches.

Program moved from spot buying to a scheduled blanket order.

"The difference showed up in the first production batch - parts that actually fit, coatings that looked right the first time. We stopped firefighting on the assembly line."

- Engineering Manager, Australian Industrial Equipment OEM

No miracle technology. Just tighter process discipline applied to sheet metal fabrication and medium plate welding.

What This Means for Your Next Project

If your current fabrication supplier is cheap but unpredictable, the real cost usually shows up later: in rework, in delayed shipments, and in the engineering hours spent fire-fighting. A stable sheet metal and structural steel OEM partner should give you consistent first-article approvals, clear inspection records, and a galvanizing process that matches Australian standards.
