Powder coating · Galvanising · Anodising
Powder coating (RAL), galvanising, anodising, shot blasting, brushing and polishing. All finishes coordinated by us, with no uncontrolled subcontracting.
We do not deliver components to assemble. We deliver what you fit, or what you install directly.
Assembly and fitting
Screwing, riveting, sub-assembly mounting. Your finished part, not your component.
Tapping and drilling
Internal threading and bolt holes done in workshop before delivery.
Deburring and edge finishing
Mechanical or manual burr removal. For parts that are handled or visible.
Adapted packaging
Pallets, cartons, interleaving. We adapt the packaging to your transport and on-site storage constraints.
Site line
Our capabilities do not stop at the workshop door. For clients who need it, Marini intervenes directly on site to install the parts we have fabricated. Elevator door reveals, façade finish panels, interior cladding: our site teams work across Île-de-France with the same level of rigour as the workshop. One point of contact. One contract. From the first cut to the final installation.
