Why buyers work with us

What you get on every order

Inspected before it ships

Tensile, impact, bend and hydrostatic testing, ultrasonic thickness measurement, spectrometric material verification and metallographic checks are carried out in our own laboratory.

Traceable paperwork

Material test certificates to EN 10204 3.1, dimensional and inspection reports, packing list and commercial invoice. Markings on the goods tie back to the heat number.

Consolidated from one works

Fittings, forged fittings, flanges, caps and pipes on one order and one set of documents, which keeps clearing and site delivery simpler.

Drawing-driven orders

Send a drawing, a size list or a take-off and we quote item by item, including non-standard dimensions and special coatings or packing.

Quality control

Every batch is checked against the standard it was ordered to, and the results travel with the goods.
