Frequently Asked Questions

What is the difference between 304 and 316 stainless steel?
304 stainless steel offers excellent general corrosion resistance. 316 stainless steel adds 2% molybdenum for superior resistance to chlorides and chemicals, making it ideal for marine and chemical environments.
Are stainless steel doors available with fire ratings?
Yes, our stainless steel doors are available with UL-listed fire ratings from 20 to 90 minutes. Fire-rated assemblies require matching stainless frames and hardware.
What finish is best for food processing?
#4 brushed (satin) finish is popular for its balance of appearance and cleanability. Bead blast is also excellent for easy cleaning. Both are hygienic and FDA/USDA compliant.
Can stainless steel doors be used outdoors?
Yes. For coastal or marine environments, we recommend 316 grade. For general exterior use, 304 grade with polyurethane core provides excellent thermal insulation and weather resistance.
What hardware should I use?
We recommend stainless steel hardware throughout to prevent galvanic corrosion and maintain appearance. Avoid mixing carbon steel fasteners with stainless doors.
