Industrial painting and abrasive blasting in Quebec City

What we do in Quebec City

We prepare and protect steel and concrete on industrial sites and structures in the Quebec City region: abrasive blasting to the specified grade, anti-corrosion painting of structures and equipment, bridge and walkway painting, tank linings, concrete protection and epoxy 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 site's ISO 12944 corrosivity category, which rises near the river, de-icing salts and process areas, then applied to the manufacturer's data sheet. Every coat is measured and recorded. We serve industrial sites and infrastructure, not residential.

Port, industry and infrastructure in the Quebec City region

Quebec City is a port city on the St. Lawrence. Quays, cranes, conveyors, silos and storage tanks at port and marine facilities live in humid air, loaded with spray in summer and de-icing salts in winter. The region's shipyards and steel fabrication shops add structures and equipment to protect, often outdoors.

The region's industry is varied: pulp and paper, food processing, manufacturing, warehousing, and water and wastewater treatment plants, each with its frames, piping, basins and floors. Infrastructure completes the picture: steel road and rail bridges, overpasses, pedestrian walkways and structures crossing the river and its tributaries. Each environment attacks steel in its own way, so the system is chosen structure by structure.

Most requested services in Quebec City

Steel structure painting and bridge painting come up most often: plant frames, walkways, pipe supports, bridges and overpasses, with a zinc-rich primer system where salts attack. Abrasive blasting comes first, under containment when the structure spans a waterway or a public road. On older structures, the existing paint sometimes contains lead: it is tested before quoting.

Hydro blasting removes salts and old paint without abrasive. Tanks and water towers need an internal lining suited to the liquid and an exterior paint that stands up to frost. Epoxy floors for food plants and shops, and protection of concrete treatment basins, round out the demand.

On site or in a shop?

On site. We have no shop in Quebec City: our crews arrive with mobile blasting, painting, dust collection and heating units, and work on your structures, inside your plants and on your infrastructure. For a bridge, a frame or a tank, dismantling and transport are not an option anyway.

A removable part can be treated in the site's maintenance shop, provided containment and ventilation are set up there. The quote states what is done in place and what requires moving the part.

Planning travel, shutdowns and traffic

Every job in Quebec City is a planned trip from LaSalle. For a plant, the window is set with the site (shutdown, line outage or zone-by-zone work), then the survey, products, abrasive, access and permits are settled remotely: confined space, lockout, work at height.

For a bridge or an overpass, planning follows the owner's requirements: traffic maintained, partial lane closures, night shifts if needed, containment and protection of the waterway. Equipment arrives before the crew so every window goes to the work. For a multi-trade project, our project management service coordinates the coatings with the rest of the schedule.

Climate: salts, humidity and winter

Quebec City's climate combines a cold, snowy winter, de-icing salts on roads and structures, and humidity from the river. Soluble salts left on steel make paint blister: they are removed by washing or hydro blasting and the surface is checked before priming.

Every product has a minimum application and cure temperature, and the steel must stay above dew point. In winter, we work under heated, ventilated enclosures with indirect heating, measuring substrate temperature, relative humidity and dew point before every coat. Bridge and exterior structure work is best placed in the warm season.

Standards and records for the owner

We apply the owner's specification, including a public owner's specification where it applies. Common references are ISO 12944 for system selection, ISO 8501-1 and SSPC/AMPP standards for the preparation grade (SSPC-SP 6, SP 10), SSPC Guide 6 for containment and SSPC-PA 2 for dry film thickness. The file handed over includes ambient conditions, thicknesses, adhesion depending on the system, data sheets and photos.
