Workshop production or on-site installation: you decide how far we go. Either way, one single contact who knows your project inside out — and picks up the phone when you call.

Fine sheet metal & steel structures
Steel, stainless, aluminium, brass, up to 1,500 × 4,000 mm. Laser, bending, welding, punching, engraving, assembly: all under one roof, one contact.

Workshop + on-site teams in Île-de-France
We fabricate and we install. Elevator door surrounds, façade finishing panels, interior cladding. Our teams work directly on site. One contact, from workshop to job site.
With most subcontractors, fabrication is handled on one side and installation on the other. You manage two contacts, two schedules, two margins for error. At Marini, you choose how far we go. We take care of the rest.
From your drawing to the delivered part
You send your files. We get back to you within 24h with a precise quote, a firm lead time, and your contact's name. No purchase orders, no client portal, no follow-up that goes nowhere. Steel, stainless, aluminium, brass. From 0.5 mm to 20 mm thickness. Up to 1,500 × 4,000 mm. Cutting, bending, welding, engraving, assembly — everything happens here, in our Livry-Gargan workshop. Your parts arrive ready to install, not ready for rework.

THEY TRUST US
From fabrication through to installation
Some of our clients don't want to manage the coordination between their fabricator and their site teams. We get it. That's why Marini offers to go all the way: workshop fabrication, then installation at your site by our own crews. Elevator door surrounds, façade finishing panels, interior cladding. We fabricate the parts and our teams can install them across the Greater Paris area within days. One contract. One schedule. One number to call if anything changes.

Door surrounds and landing cladding. We fabricate in custom brushed stainless and install on site. Coordinated with your commissioning schedule.

Finishing panels, cladding, roofing. Fabrication and installation coordinated with your other trades. Zero interfaces to manage.

Cladding, partitions, metal furniture. We step in during the finishing phase, when every millimetre counts.
Our clients come from very different backgrounds. What they have in common: they need custom metal parts, made right, delivered on time, by someone who understands their constraints without needing everything explained twice.
Landing doors, cab cladding, shaft panels, sills. Regular delivery cadence. Partners: KONE, TKE, OTIS, Schindler.
Aluminium cassettes, roofing, structural metalwork. To architect drawings. Clients include Bouygues, VINCI, Eiffage.
Frames, precision parts, prototypes, series runs. No minimum order.
Ducts, supports, custom connecting parts. Galvanised steel or stainless as required.
Brushed stainless, perfect corners, finish-ready. No rework at delivery.
Polished brass, mirror stainless, raw steel. Work under NDA. Full confidentiality.
