Stainless Steel Corrugated Roofing, Siding & Flooring
We manufacture stainless steel panels and deck for roofing, siding and flooring in settings where corrosion cuts the life of other metals short. Our stainless roof and floor deck is available from 16 to 22 gauge, composite floor decks come in stainless for floor systems, and the same material is formed into corrugated siding profiles for walls.
What Is Stainless Steel?
Stainless steel is steel alloyed with at least 10.5 percent chromium, usually along with nickel and, in some grades, molybdenum. The chromium reacts with oxygen to form a thin, invisible film across the surface that blocks rust and rebuilds itself when the metal is scratched. Because that protection is part of the metal rather than a coating, it does not wear away like a painted or plated finish. The grade you choose sets how well a panel stands up to salt, chemicals and heat, so it matters for roofing, siding and flooring.
Key Benefits of Stainless Steel
Stainless steel earns its price where other metals wear out. These are the properties that matter most when you are choosing it for roofing, siding or deck.
- Corrosion resistance (a chromium oxide layer protects the surface)
- Durability in harsh settings (marine, chemical and industrial)
- Strength at high temperatures
- Hygienic surface (smooth, non-porous and easy to clean)
- Finish options (brushed, polished and matte)
- Recyclable (100 percent recyclable, with a long service life)
Common Uses for Stainless Steel Roofing, Siding and Flooring
Stainless steel earns its place where moisture, chemicals and sanitation rules shorten the life of other metals. The settings below are where it does the most good.
Food Processing Facilities
Wash-down schedules and strict hygiene rules put walls and ceilings through constant cleaning. Stainless panels are non-porous, so bacteria have nowhere to settle, and they resist rust under repeated cleaning chemicals. That makes them a common choice for food processing plants.
Pulp, Paper and Chemical Plants
Mills and chemical plants expose roofing, siding and deck to moisture and corrosive vapors all year. Stainless steel holds up where galvanized coatings wear through, which is why it suits pulp and paper facilities and other process buildings.
Marine and Coastal Buildings
Salt air attacks exposed metal quickly. Stainless steel resists that corrosion, and a higher grade holds up best against constant salt exposure, so it suits roofing and siding on waterfront and coastal buildings where maintenance access is limited.
Stainless Steel Grades We Offer
The grade decides how a stainless panel behaves in your building’s environment. These two cover most roofing, siding and deck work.
- 304 stainless steel is the general-purpose grade, with about 18 to 20 percent chromium and 8 to 10.5 percent nickel. It resists corrosion in most roofing and siding settings, including food processing and many chemical areas, and it costs less than 316.
- 316 stainless steel adds 2 to 3 percent molybdenum, which improves resistance to pitting in salt air and chloride exposure. It is the better pick for coastal, marine and harsher chemical settings, and it costs more than 304.
Stainless Steel vs. Aluminum
Aluminum is the lighter choice. It weighs about a third as much as steel, resists corrosion on its own and usually costs less, which suits roofs and walls where weight matters. Stainless steel is the stronger metal and keeps its strength at high temperatures, and its smooth surface stands up to repeated chemical cleaning, so it is the better fit for food processing, chemical plants and other wash-down settings. We help you choose based on the building and its exposure.
Custom Stainless Steel Panel Supplier for Roofing, Siding and Deck Projects
Every stainless order is cut to the lengths on your drawings, which means less trimming on site and fewer offcuts. We supply stainless deck from 16 to 22 gauge and work with contractors and builders on food processing, chemical and industrial projects.

FAQs
Stainless steel resists rust far better than coated steel, but it is not rust-proof. The chromium in the metal forms a thin protective layer that repairs itself when the surface is scratched. In salt air or around chlorides, the surface can still pit or show brown tea staining if the grade is too low for the setting, which is why grade selection matters near the coast and in chemical plants.
The two common grades are 304 and 316. Grade 304 handles most roofing and siding jobs, including food processing and many chemical settings, and it costs less. Grade 316 adds molybdenum, which improves resistance to pitting in salt air and chloride exposure, so it is the better pick for coastal and marine buildings. Tell us where the building sits and what it is exposed to and we will recommend one.
Published life-cost data puts stainless steel roofing at about 50 to 60 years when the grade matches the environment. Life drops in marine and heavily polluted air, especially with a lower grade, so a coastal or chemical-plant roof usually calls for 316. Correct installation matters as well.
