Do you have customers who can't find the tubing they need?
We manufacture it. Let's talk.

Delmàs is a family-owned business with 65 years of experience manufacturing precision welded and calibrated steel tubing in the diameters the standard market fails to reach. We are looking for distributors with local warehousing in markets where our end customers need us — and where we cannot provide, on our own, the proximity our business philosophy demands. We are looking for partners to offer a 360º service.

The product the mass market cannot offer you

Precision steel tubing from 3 mm to 25 mm — with the exact diameters each design requires, controlled inner bead and a surface finish ready for direct chrome plating — is a product that large steel mills simply do not manufacture. Not because they can't, but because they don't want to. The volumes are too small and the specifications too demanding for their mass-production models. We are looking for the partner who can combine our solution with local service in their territory. Not a commercial transaction — a long-term relationship between professionals who take pride in what they do and trust in each other.

Exact diameters to the tenth: 7 mm, 8.1 mm, 9 mm — what the design demands

Flexible orders — pilot order possible, progressive ramp-up

Technical response in 24 h, production and delivery per project

Coil, cut-to-length, standard length or transformed part ready to assemble

Inner weld bead ≤ 0.15 mm controlled on every metre — silent rotation guaranteed

Bright surface from the mill — direct to the galvanic bath, no preparation

Mirror bore equivalent to seamless extruded tube — 40–80% lower cost

Engineering team that co-designs the solution with the end customer

As a distributor, you offer three solutions. One for each problem.

1 nichePrecision steel tubing

A manufacturer with a name of its own

Delmàs is a family business founded in 1956. We are not the export department of a steel multinational. We are a team of specialised people who have been manufacturing the same product for the same industry for decades — who respond within 24 hours to a technical query and send a physical sample when a customer needs to validate before committing.
There are companies in every market technically satisfied with the quality of the tubing they receive from their current supplier, but fed up with the service. Of not knowing who they are speaking to. Of waiting weeks for a response. Of receiving the same catalogue with no adaptation. Of feeling too small for anyone to care about their issue. At Delmàs, the size of the customer does not determine the quality of the service.
"Our customer doesn't buy a tube. They buy the certainty that when the tube arrives it will work exactly as they need it to — and that if something goes wrong, there will be someone at the end of the phone who knows it, understands it and resolves it."

100% renewable

A real ESG argument for your customers

The Delmàs plant runs on 100% renewable energy generated by its two photovoltaic facilities. For your customers with ESG commitments, carbon footprint audits or tenders with sustainability criteria, the renewable origin of the energy used to manufacture the tube is a real purchasing argument — and we can document it.

Standard product certificate. Every delivery includes a certificate with steel composition, mechanical properties, verified dimensions and applicable standard. It is not an additional document: it is our standard.

Your customer has a supplier. But does he get the service he deserves?

What your customer puts up with from their current supplier What your customer will get with Delmàs through you
Calls with a technical question and gets bounced from department to department
Speaks directly with the technical team that manufactured their tube
Requests a non-standard diameter and is told it's not possible
Asks for 8.1 mm and Delmàs makes it — in the exact wall thickness and finish
Reports a quality incident and it takes weeks to be resolved
If there's an incident, there's a response within 24 hours and a solution within days
The product certificate arrives incomplete or doesn't arrive at all
Standard product certificate with every delivery, no need to ask
Requests a small pilot order and is forced into an unworkable MOQ
Pilot order possible — no punishing MOQ to start the relationship
Nobody at the supplier knows their application or has ever asked about it
The technical team knows their sector and application before the first call
When there's an urgent problem, there's no one by name to call
There are real people, with real names, they can trust
As a distributor, you offer your customer something no large steel mill can offer: the combination of real technical precision and genuine human service. That combination is what builds loyalty — and what justifies the price. With Delmàs, distributors get access to a highly specialised market niche that today is not fully covered.
