The situation
An Australian equipment OEM was buying steel structures for industrial storage systems. Welds were uneven, length tolerances drifted, and the hot-dip galvanising was too thick — the zinc layer cracked and residue blocked threaded holes.
What we did
We reassigned welding to a named, experienced welder at the workshop, worked with both the buyer and the factory to redefine the surface treatment specification, and agreed the hot-dip galvanising parameters, verified on a sample. We then sampled surface finish and dimensions and locked a stable production schedule.
The result
Welds came out clean and consistent, with dimensions inside tolerance. The galvanised finish was smooth and corrosion resistant. Unit cost came in 12% below the previous supplier, with stable ongoing supply.
