Grain silos. Processing lines. Mechanical assembly.

Design, delivery and mechanical and electrical assembly for grain silos, mills and feed plants, seed processing lines, dryers and biogas plants. Electrical installations and automation for processing lines of any complexity, built on the customer's own site.

About us

One contractor
from the foundation to the first tonne in store

Rosilo designs, delivers, installs and integrates grain storage and conditioning systems of any size and complexity. We work for farmers, agricultural associations and grain traders, alongside established silo manufacturers.

We started with the mechanical and electrical assembly of grain silos. Today we also cover what comes before and after: civil works, foundation design and construction, the design, fabrication and erection of steel structures, elevator towers, electrical installations and control panels.

We work on the customer's own site, in Romania and abroad. Because we have projects running all year round, we can also take on work at short notice.

The team

Every trade turns up on site at once

A silo does not go up with one trade. In the same few weeks the site has steel fixers, fitters, welders, crane operators, electricians and control engineers on it. If one of them runs late, the rest wait.

We bring all of them and schedule them one after another: the foundation, the steelwork, the equipment, the cabling, the control panel, the software. You get one programme to follow and one person to call when something goes wrong.

How we work

One route, from bare ground to the first tonne in store.

We do not take on just a slice of the job. We come in at the site survey and leave once the plant has run with grain in it. Every stage has an owner, a deadline and a written handover to the next one — that is how you avoid the gaps where a site sits idle.

Site survey

We measure the site, check access, utilities and the founding soil, and work out what capacity makes sense for your flow.

Handed onthe proposed capacity and the site constraints, in writing

Design

Foundation, steelwork, electrical and control drawings, matched to the chosen equipment and to the silo manufacturer.

Foundations and groundworks

Formwork, reinforcement, pours and connections, with levels checked before assembly starts.

Handed onthe checked levels and a platform ready for assembly

Mechanical assembly

Silos, elevators, conveyors, dryers, cleaning equipment and the structures that carry them, installed to the manufacturer's documentation.

Electrical and automation

Power and control installation, the control panel, and the intake, drying, transfer and dispatch sequences.

Commissioning

Trials with grain, adjustments and training for your own people.

Mechanical assembly

Silos, dryers and grain handling lines

We install flat-bottom and hopper-bottom steel silos, elevators, chain and screw conveyors, belts, separators, weighers and aspiration systems. We work to the manufacturer's documentation, checking levels as we go and running a tightness test wherever the design calls for one.

Electrical and automation

Electrical installations and automation

We design and build the power and control installation, manufacture the control panels and program the intake, drying, transfer and despatch routes. The plant is handed over commissioned, tested and fully documented.

Projects

Projects carried through to the end.

From a farm with two bins to intake facilities of tens of thousands of tonnes, in Romania and beyond. Drag the handle to see the same site during assembly and once finished.

From equipment craned onto the slab to a line installed and connected: chipping, drying, pelleting and conveying, with the electrical installation and the automation.

Assembly had already started when we came on site. We took the job through to the end: silos, conveyor galleries, walkways and the fumigation system for the rice.

Sectors

Experience across different kinds of plant

We work on plants that differ widely in size and purpose, adapting our organisation and method to what each site actually needs. Every kind of job has its own procedures, timings and rhythm: we set the site up around the production flow and around the equipment. From a farm with two bins to an intake facility of tens of thousands of tonnes, the approach stays the same — fit quickly into the customer's organisation and carry the job through with precision and continuity.

Where we work

From Norway to Iraq

We work in Romania and abroad, alongside silo manufacturers and agri-industrial groups, on the assembly, installation and commissioning of their plants. The method stays the same whatever the country; only the local regulations and the logistics change.

Romania England Spain France Netherlands Germany Denmark Norway Sweden Czechia Austria Hungary Croatia North Macedonia Italy Iraq

On site

We work alongside your designers, site managers and staff, from mechanical assembly through to commissioning. We fit into the way the site is run, not the other way round.

Confidentiality, always

We work with equipment manufacturers and agri-industrial groups who give us access to their plants, technical documentation and production processes. We treat all of it as confidential.
