Industrial painting and abrasive blasting in Trois-Rivières

What we do in Trois-Rivières

We prepare and protect steel and concrete on industrial sites in Trois-Rivières: abrasive blasting to the specified grade, anti-corrosion painting, immersion linings for tanks, steel structure painting and plant floors. Work is carried out by our crews and qualified subcontractors, under one quote and one inspection file.

Coatings are our core business. The system is chosen from the ISO 12944 corrosivity category of each zone, process chemistry and mechanical wear, then applied to the manufacturer's data sheet. Every coat is measured and recorded. The service is for industrial sites only: we do not do residential work, garages or houses.

Industrial sectors in Trois-Rivières

Trois-Rivières grew around pulp and paper, where the Saint-Maurice meets the St. Lawrence, and industry is still at the heart of its economy. Pulp and paper mills have equipment to protect from a hot, humid and often chemical atmosphere: chests, liquor tanks, hoods, machine building frames, piping and floors.

The city's industrial parks bring together metallurgy, metal fabrication and processing plants, with their steel structures, overhead cranes, conveyors and production areas. The port, on the St. Lawrence, adds docks, handling structures, bulk tanks and equipment exposed to water, wind and de-icing salts. Each environment attacks steel and concrete in its own way, so the system is chosen zone by zone rather than one product for the whole site.

Most requested services in Trois-Rivières

Steel structure painting comes up most often: building frames, crane runway beams, walkways, pipe supports and port structures, with a system suited to humidity and process vapours. Abrasive blasting almost always comes first, dry or wet to limit dust in a running plant.

Hydro blasting removes process deposits and old coatings where abrasive is hard to recover. Tanks and chests need an internal lining suited to the stored liquid and its temperature. Plant floors (machine rooms, shops, wash areas) receive epoxy flooring or a polyurea coating depending on traffic, chemicals and the downtime available. For steel exposed to splash and abrasion, thermal spray metallizing is an option worth considering.

On site or in a shop?

On site. We have no shop in Trois-Rivières: our crews arrive with mobile blasting, painting, dust collection and heating units, and work inside your buildings, on your structures and in your tanks. For a frame, a tank or a floor, this is often the simplest option, since there is no dismantling and no transport.

For a removable part, the site's maintenance shop can serve as the work area, provided the necessary containment and ventilation are set up. The quote states what is done in place and what requires moving the part.

Planning travel and shutdowns

A trip to Trois-Rivières is prepared from LaSalle so that time on site goes to the work itself. First, the window is set with the site: annual shutdown, machine outage, zone-by-zone work in operation, or a mix of both. Then everything that can be settled remotely is settled: survey from your photos and drawings, product quantities, abrasive, scaffolding or lifts, and the permits the operator requires (confined space, lockout, work at height, hot work).

Equipment and products arrive before the crew. When a site in Bécancour, across the river, has similar needs, jobs can be grouped on the same trip.

Climate: humidity, vapours and winter

In Trois-Rivières, two environments combine: cold, salty winters outdoors and hot, saturated air inside the plants. Every product has a minimum application and cure temperature, and a coat applied on steel too close to dew point bonds poorly. We therefore measure substrate temperature, relative humidity and dew point before every coat, and work under heated, dehumidified enclosures when needed.

When the site allows it, exterior work is placed in the warm season and interior work during winter. If conditions are not met, the coat waits.

Standards and inspection records

We apply the owner's specification. Common references are ISO 12944 for system selection by corrosivity, ISO 8501-1 and SSPC/AMPP standards for the preparation grade (SSPC-SP 6, SP 10), and SSPC-PA 2 for dry film thickness measurement. At the end of the job, the site receives a file: ambient conditions, preparation grade, thicknesses, adhesion and continuity depending on the system, data sheets and photos.
