Industrial painting and coatings in Longueuil

What we do in Longueuil

We prepare and protect steel and concrete on Longueuil industrial sites: abrasive blasting or mechanical preparation, anti-corrosion painting of structures and equipment, internal and external tank coatings, epoxy floors and concrete protection. Work is carried out by our crews and qualified subcontractors, with one contact and one inspection file.

Coatings are our core business. Each system is chosen from the location's ISO 12944 corrosivity, the process and the operating constraints, then applied to the manufacturer's data sheet. We serve industrial sites only, not residential.

Industrial sectors in Longueuil

Longueuil is a hub for aerospace and advanced manufacturing, with machining, metal processing, food, chemicals and logistics around its industrial parks. The river and the major highways also make it an area for warehouses and transfer facilities.

Needs vary a lot from one site to the next. A metal parts plant wants floors that stand up to cutting oils and forklifts. A chemical plant has tanks, containment basins and pipe supports exposed to vapours. Outdoor structures near the river face humidity, spray from fresh water loaded with road salt, and frost.

• Tank lining

Most requested services in Longueuil

Three requests come up often. First, steel structures: frames, walkways, pipe supports and conveyors, repainted zone by zone with a system compatible with the old film. Second, tanks: an internal lining chosen for the stored product, exterior paint, and sometimes metallizing on the most exposed parts. Third, epoxy floors for production areas, shops and docks.

Abrasive blasting is done under containment when the site allows it. Otherwise, hydro blasting or power tool preparation takes over, especially near dust-sensitive equipment.

On-site work in running plants

Work is done on site, inside your plant. Our crews bring the blasting, painting, dust collection and heating units needed, and set up enclosures wherever the zone has to be isolated. For aerospace and food sites, cleanliness and particle control are settled before work starts.

Removable parts can be treated in the site's maintenance shop if it can be ventilated and contained. The quote states what is done in place and what is moved.

Access and planning from LaSalle

Longueuil is close to LaSalle, but the river crossing drives the schedule: bridges and the tunnel are often congested, and we plan equipment arrival outside peak hours. Surveys and small jobs require no lodging.

For a shutdown, the window is set with you first, then quantities, scaffolding or lifts and internal permits (confined space, lockout, work at height). Our project management service coordinates coatings with the other trades.

Climate along the river

Along the St. Lawrence, humidity stays high much of the year, and winters alternate frost, thaws and de-icing salts. On exterior steel, this raises corrosivity and speeds up rust at joints, bolts and beam edges. On concrete, freeze cycles spall surfaces that are already cracked.

We measure substrate temperature, relative humidity and dew point before every coat, and concrete moisture before a floor. Exterior work goes in the warm season; in winter, work is done under a heated enclosure or indoors.

Standards and inspection records

We apply the owner's specification. Common references are ISO 12944 for system selection, ISO 8501-1 and SSPC/AMPP standards for preparation (SSPC-SP 6, SP 10), SSPC-PA 2 for dry film thickness and SSPC-CS 23.00 for metallizing. The site receives a full file: ambient conditions, preparation, thicknesses, adhesion and continuity depending on the system, data sheets and photos. Independent third-party inspection can be added when your specification calls for it.
