Painting/Refinishing of Metal/Steel/Aluminum Siding on Industrial Buildings, Factories & Plants
Everyone wants a paint job or refinishing job to last as long as possible. This task is made more difficult with exterior exposure, since paint finishes have to deal with sun, rain, temperature fluctuations and more, all of which wreak havoc with a paint finish.
Nowhere is this more of a problem than when refinishing exterior steel/metal clad or aluminum clad siding on a large industrial building, plant or factory. Particularly in the spring and fall when daily temperature variations are the highest, the metal substrate heats up and expands during the day, while at night it cools and contracts considerably when compared to any other painted surface.
Industrial Metal Siding Coating & Refinishing Systems
This means the coating used for industrial building siding refinishing has to be designed for high levels of expansion and contraction, or it will soon crack and fail as it is stretched beyond its capabilities. Highly flexible coatings are required, combined with excellent fade resistance and gloss retention to withstand the sun exposure.
Coating selection becomes even more important when dark colours are being used since they absorb more heat during the day; the dark surface can become over 50 degrees F hotter than a comparable light-coloured surface.As well, fading is more noticeable on dark colours, so colour retention characteristics are more important.
Regular industrial paints generally don’t have the high quality inorganic pigments, resins, or correct gloss levels required to duplicate the original factory finishes. If the refinishing is to match the original factory finish in both gloss and colour, you also need to make sure the gloss of the refinishing enamel is correct.
At Induspray, our refinishing systems for metal/steel siding applications are custom made for us by the original coil coating manufacturers to the much higher performance criteria of the original coating specifications.
Understanding Industrial Metal Siding Deterioration
Industrial metal siding is constantly exposed to environmental and mechanical stress. Over time, these factors contribute to coating failure and surface damage:
- Prolonged UV exposure causing fading and chalking
- Moisture and humidity leading to corrosion and rust
- Temperature fluctuations resulting in expansion and contraction
- Airborne pollutants and industrial residue buildup
- Aging factory-applied finishes losing adhesion
Without proper protection, deteriorating metal siding can compromise both aesthetics and structural integrity. Professional industrial metal siding painting addresses these issues before they lead to costly repairs or panel replacement.
Benefits of Professional Industrial Metal Siding Painting
Investing in professional metal siding painting delivers measurable long-term value:
- Extends the service life of existing metal panels
- Provides a durable barrier against rust and corrosion
- Improves resistance to moisture, chemicals, and pollutants
- Restores a clean, uniform exterior appearance
- Enhances corporate image and property value
- Reduces long-term maintenance and capital replacement costs
For many facilities, repainting metal siding offers a return on investment that far exceeds replacement alternatives.
Our Industrial Metal Siding Painting Process
1. Site Assessment & Coating Specification
Every project begins with a detailed site inspection. We evaluate substrate condition, existing coatings, corrosion levels, and environmental exposure to specify the most appropriate coating system for long-term performance.
2. Surface Preparation
Proper preparation is critical to coating success. Our preparation methods may include:
- Power washing and industrial cleaning
- Removal of dirt, grease, and contaminants
- Mechanical or chemical rust removal
- Spot repairs to damaged or deteriorated panels
This ensures optimal adhesion and coating longevity.
3. Rust Inhibition & Priming
For steel and corrosion-prone substrates, we apply specialized rust-inhibitive primers that stabilize the surface and prevent future oxidation. Primers are selected based on substrate type and environmental exposure.
4. High-Performance Coating Application
We apply premium industrial coatings such as acrylics, urethanes, and elastomeric systems engineered for metal siding. These coatings provide:
- Flexibility to handle thermal movement
- Strong adhesion to metal substrates
- UV and weather resistance
- Long-term colour and gloss retention
Advanced airless spray equipment ensures uniform coverage across corrugated profiles, seams, fasteners, and architectural details.
5. Quality Control & Final Inspection
Each project undergoes thorough inspection to confirm proper film thickness, adhesion, and finish quality before completion.
Types of Industrial Metal Siding We Paint
Our expertise covers a wide range of metal siding systems, including:
- Steel siding panels

Coatings Designed for Ontario’s Climate
Ontario’s climate presents unique challenges for exterior metal surfaces. Our coating systems are selected to perform in:
- Extreme temperature variations
- High UV exposure during summer months
- Freeze–thaw cycles and moisture intrusion
- Snow, ice, and road salt exposure
These coatings remain flexible, resist cracking, and maintain appearance year after year.
Minimal Disruption to Operations
We understand that industrial facilities must remain operational. Our project management approach focuses on safety, efficiency, and minimal disruption:
- Phased work plans for large facilities
- Off-hour and weekend scheduling options
- Strict safety and access control procedures
- Clear communication with facility managers
This allows painting work to proceed without interrupting daily operations.
