5S on a fabrication floor: what it changes in practice
What 5S changes on a fabrication floor: search time, mixed-material risk and the record an auditor samples, with the numbers that justify the effort.

Plant, quality and sustainability
Buyers audit a system, not a brochure. This cluster covers how Ganesh runs its plants: the ISO 9001 and ISO 14001 systems, in-process inspection, calibration and gauge control, pretreatment chemistry, the effluent treatment plant, maintenance, energy use and scrap recovery. It is written so a supplier-audit team knows what to ask for and what good evidence looks like.
Guides in this topic
How the plants run: quality systems, inspection, calibration, pretreatment chemistry, effluent, maintenance, energy and scrap.
Supplier non-conformance: how incoming material is checked
How incoming material inspection works on a sheet metal plant: the checks that catch a bad coil, the NCR fields, and the sample that proves nothing.

Training and competence: who is allowed to set a press or a brake
Who may set a press or a brake, what the authorisation has to record, how competence is assessed, and the die damage an unauthorised setter causes.

Environmental aspects register: what ISO 14001 actually requires
How the aspects and impacts register is built, scored and evidenced, and the four records an ISO 14001 auditor actually samples on a sheet metal plant.

Warehouse and WIP control: parts between operations
WIP age is a quality metric, not a scheduling one. Little's Law, the four damage mechanisms between operations, and the storage rules that stop them.

Packaging for transit: protection without over-packing
Most transit damage on sheet metal is compression, abrasion and condensation, not distance. How to size a pack to the part, and where over-packing backfires.

Surface roughness measurement: Ra, Rz and what a drawing should call
Ra averages a profile and hides the one deep striation that fails a gasket. What Ra and Rz measure, the cut-off a drawing must state, when to call Rz instead.

Internal quality audit: closing the non-conformance loop
An audit is measured by how many findings stay closed a year later. How a non-conformance loop closes: containment, root cause, the process change, and the effectiveness check.

Coating thickness measurement: DFT gauge use on curved and edged parts
A DFT gauge reads a flat foil correctly and a 10 mm radius wrongly. How probe geometry, edges and blast profile shift the number, and where to read.
