Organic coated steel isn’t a new vogue veggie dip treatment for metal. Of course, you already knew that. So, what is the deal when it comes to organic coated steel? In the world of organic or inorganic coating for steel, the options depend on the application and environmental factors.
To cut a long story short, coating steel is all about providing corrosion resistance. Metallic (aka galvanizing) and tinplating are of the inorganic sort. But be prepared to be impressed with the impressive repertoire of organic coating applications.
The Versatility of Organic Coated Steel
To be accurate, and to get you geared for ‘organic speak’, the coating still references a paint finish. Most frequently of the hot-dip galvanized steel sort, organic coated steel remains firmly in the PPGI (Pre-Painted Galvanized Iron) classification.
Produced on continuous laminating machinery, in a very controlled environment with any number of cleaning and coating procedures, the coatings are baked at very high temperatures.
Organic coating is perfect for electronic housings, decorative partitioning, lifts, ceiling, and furniture applications. There are two types of organic coated steel:
- Polyvinylidene fluoride paint (PVDF – also GI, but that makes the acronym way too long)
- Polyester Paint (PPGI)
Polyester coated steel is chiefly used for industrial purposes, sheds, and roofing. Polyvinylidene fluoride coated steel is more costly due to its additional high impact, scratch-resistance, long anti-fading, and anti-ultraviolet performance. For applications where wear, tear, and high corrosion exists, the cost wins out over corrosion issues down the line.
It doesn’t end there, organic coated steel is highly sought after, and the preferred option for a wide range of applications.
Indoors:
- Refrigeration rooms, with all their stringent requirements.
- 100%biobased resin, which also improves indoor air quality in HVACs.
- Grained anti-scratch for high traffic or robust purposes.
- Light matt finishes for reduced marking resistance.
- Creative design requiring flexibility and aesthetics.
Outdoors:
- Organic coated steel ranges offer exceptional corrosion resistance for agricultural, corrosive, and other aggressive environments.
- Rainwater applications will find the robust coating satisfying.
- Roofing options include a variety of finishes suitable for architectural facades.
- Colour stability in all weather environments.
Organic coated steel is surprisingly rewarding wherever oxidizing and corrosion resistance is paramount. That it has both interior and exterior use incorporates, appliances, decorative features, metal furniture, and wall paneling. Architectural innovators and civil engineering professionals are spoilt for choice and doesn’t that make organic coating a veritable ‘steel’?
