Six instruments, six checkpoints, and one rule: nothing ships on a promise. Below is what we actually measure, and what arrives in the container with the steel.
None of these is a formality. Each one exists because something specific goes wrong without it.

Internal flaws in butt welds. Run over 100% of main seams, not a sample.

Surface cracks at fillet welds and stiffener connections.

Plate tensile and yield, re-checked on arrival against the mill certificate.

Deflection under load on the test rig, logged rather than estimated.

Hairline cracks the eye misses — corners, transitions, repair zones.

Dry film thickness after each coat, member by member.
Six gates. A member does not move to the next one until the previous gate is signed.
Every heat checked on arrival; the mill certificate is filed against the batch.
Cut positions held to ±1.0 mm from the model.
Dimensions and squareness checked before the first pass.
100% ultrasonic coverage on main seams. Repairs are re-tested, not signed off.
Surface preparation first, then dry film thickness per coat.
Each member numbered, photographed and listed.
Six documents travel in the container. Domestic clients are welcome to attend the loading in person.
By mark number, with bundle weights and sizes.
Item, quantity and weight, matched line by line to the packing list.
Issued for the destination country as required.
The signed commercial contract, one copy with the goods.
Original or telex release, as agreed.
Filmed bundle by bundle, from the first lift to the doors closing.
Every line below is a certificate we hold today. Copies go out with the quotation, before you ask.
