Who we are
VANKKA rolls, cuts, folds and finishes steel in its own facility in Finland. The profiles, the trims that close them and the bespoke pieces that no catalogue covers all come off the same lines, out of the same coil.
That matters more than it sounds. A trim folded from the same batch as the roof matches it exactly — a trim bought elsewhere in the same nominal colour never quite does. A profile drawn and produced under one roof can be engineered for the load it will actually carry rather than selected from a table. And when a specification is wrong, the person who tells you is the person who would otherwise have manufactured it.
Everything we make is designed for a climate that finds every weak detail: a hundred-degree annual temperature swing, months of standing snow, meltwater, and a freeze-thaw cycle that works at a roof until something moves. Products engineered for that perform comfortably wherever else they are installed.
Products
Complete systems and the profiles, trims, flashings and fixings that finish them — specified together, produced together, delivered together.
Why VANKKA
In-house manufacturing is not a marketing line — it is what makes precision, traceability and honest lead times possible in the first place.

We form, cut, fold and finish in our own facility. Nothing critical is subcontracted, so nothing critical is outside our control.
Products are engineered for a hundred-degree annual temperature swing, months of standing snow and a freeze-thaw cycle that finds every weak detail.
Every delivery carries its production run and batch. A matching sheet can be produced years later.
If the profile you asked for is wrong for your pitch or span, we say so before the order, not after the roof is on.
What we do
Most of what separates a roof that works from one that leaks is decided before anything is manufactured. We are involved in that part too.
Roof and facade systems, profiles, trims, flashings, rainwater goods, safety products and fixings — from one manufacturer, on one delivery program.
Profile selection, load-span checks, fixing patterns, detail drawings and build-up advice, from the people who make the product.
Bespoke trims, flashings, architectural panels and non-standard lengths, folded to your drawing on the same brakes as the standard range.
Supply arrangements for contractors, merchants and distributors across Europe and North America, with agreed ranges and account terms.
VANKKA in numbers
This band is wired to the company data file and will fill in the moment VANKKA confirms each figure. We would rather show an empty slot than a number nobody has checked.

Finland · Europe
Finland is where VANKKA is engineered and made. Coil handling, roll-forming, coating inspection, cut-to-length and custom bending all happen under one roof, alongside the technical team that specifies the systems. Every profile leaving the line is measured against the same tolerances, whether it ships to a site an hour away or across the Atlantic.
