When a Lower Anode Price Creates More Work: A Real Sacrificial Anode Quality Story
Our anodes were more expensive.
For a long time, that was enough reason for a customer I’ll call Mark to keep buying from another supplier.
We already knew each other, and I had tried more than once to win his business.
Then one large shipment changed the conversation.
Mark told me that several high-volume weld-on anode models in that shipment were around 10–15% below their declared weight.
Not every model was affected. But enough were.
Mark told me the problem reached his customers. Bad online reviews followed, his online sales dropped, and he spent more than €10,000 on advertising trying to repair the damage.
He also had to clear the affected stock at very low promotional prices.
I do not know why his previous supplier shipped them that way.
Maybe price pressure played a part. Maybe something else happened.
I will not invent the answer.
What I could see was much simpler: the low purchase price had created a lot of work later.
For readers who want the technical background first, see how sacrificial anodes protect boats and our plain-English guide to galvanic corrosion.
Earning the trust back through the work
When Mark finally gave Nautical Armor a chance, our price was still higher.
So we had to earn his trust through the work.
We showed him our ±3% weight tolerance, weighing and measurement checks, production photos, and what was happening with his orders before dispatch.
I stayed directly involved, answered his questions quickly, and gave him as much transparency as I could from production to shipment.
The scale photo shown here is from one of his Nautical Armor orders: a nominal 12 kg PRP-800479 reading 11.70 kg, inside our ±3% weight tolerance.
Every outgoing Nautical Armor shipment still passes through my final inspection. Depending on shipment size, I inspect around one third of the anodes inside it on average.
What should be checked before sacrificial anodes are dispatched?
For a buyer comparing sacrificial anode suppliers, weight is an obvious place to start. It should not be the only check.
Before dispatch, our process can include checking:
- nominal weight against the defined tolerance;
- dimensions and mounting points;
- model identification and quantity;
- packing and agreed labels;
- COA and traceability requirements;
- final condition before the shipment is handed to transport.
The exact checks depend on the product and order.
The purpose is straightforward: catch something on our side while there is still time to correct it.
Years later, our checks stayed the same
Years later, Mark is one of our core clients.
He buys more anode models from us. The weight complaints stopped. He needs to check less on his side.
Our own checks stayed exactly the same.
That matters to me because Mark never wanted to sell “just anodes.”
He built his company to be known for premium products, quality, and reliability. He wanted to be proud of the name his customers see.
Our job is to help him protect that.
If I were comparing sacrificial anode suppliers today, one question would be near the top of my list:
How do you verify weight before dispatch?
A scale is a very boring piece of equipment.
I have learned to appreciate boring equipment. 😉
