About Calder
Our story
How Calder works
Calder has built its business on being the supplier that does not cause problems. That sounds modest and it is the hardest thing in this industry: parts that conform, delivered when the schedule said, with the paperwork that proves it. We invest in inspection rather than in sales. Our customers audit us, and we would rather pass an audit than win a pitch. Where a design will be difficult or expensive to make, we say so at quotation stage — most of the value we add is in that conversation.

Why us
What makes us different
01
Conformance, documented
Inspection reports and material certification as standard. You should not have to ask for proof.
02
We tell you at quotation
If a feature will cost you money for no functional gain, you will hear it before you commit.
03
Schedules that hold
Our on-time delivery figure is the number we are judged on, and we publish it to our customers.
04
Under one roof
Machining, fabrication, assembly and inspection in one place. Fewer handoffs, shorter lead times.

Quotations usually come back within two working days, with a note on anything in the design that will cost you more than it needs to.
