Relay for BMW 3 Series: Powder Coated Steel
This relay for the BMW 3 Series is specified around powder coated steel, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is a fitment that looked right on paper and failed on the bench, or a specification nobody had written down. Both are specification problems, and both are preventable.

Questions buyers ask
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
What testing is included?
Standard lots ship with dimensional and hardness reports. E-mark documentation is issued with the shipment when your market requires it.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
