About
HELDECO.
01

Owner-managed.

Since 1991, HELDECO has stood for technical responsibility, short decision-making processes, and solutions that are personally overseen.

02

Technologically.

State-of-the-art machinery, in-depth material knowledge, and experienced specialists form the basis for large-scale precision manufacturing.

03

Cross-industry.

We work for globally operating clients and take on tasks where scale, complexity, and quality come together.

When it gets heavy.

HELDECO takes over where standard manufacturers stop.

Large components. Heavy parts. Complex spares.
Tight tolerances.

HELDECO is then called upon when industrial requirements don't fit into simple grids.
