316 Stainless Steel Enclosures & Surface Finish
Superior Quality, Protection, and Longevity
B&R Enclosures specialises in manufacturing high-quality enclosure solutions for harsh and demanding environments. We use only premium 316-grade stainless steel, combined with advanced manufacturing and finishing techniques, to deliver durable, long-lasting products. B&R Enclosures is accredited by the Australian Stainless Steel Development Association (ASSDA), ensuring our processes align with recognised industry best practice.
Surface Finish Excellence
Our 316 stainless steel enclosures are finished to an exceptionally smooth surface roughness of Ra 0.4 μm, surpassing many industry competitors who typically achieve Ra 0.5 μm or higher. ASSDA advises that there is a marked decrease in corrosion resistance as surface roughness increases above approximately Ra 0.5 μm.
This finer surface finish significantly reduces the ability of salts and contaminants to adhere to the enclosure surface, helping to minimise corrosion and extend service life. The result is not only improved performance in corrosive environments, but also a higher-quality appearance and feel.
The smooth finish also makes our enclosures well suited to food and beverage processing applications, where cleanability and hygiene are critical.
Why 316 Stainless Steel?
316 stainless steel offers similar mechanical and physical properties to the more common 304 grade but provides substantially improved corrosion resistance, particularly against pitting corrosion in chloride-rich environments. This type of corrosion is prevalent in Australian conditions, both in coastal regions and inland areas where groundwater salinity can be high.
B&R further enhances this natural corrosion resistance by applying a specialised N4 surface finish and adhering strictly to ASSDA manufacturing guidelines.
The smooth finish also makes our enclosures well suited to food and beverage processing applications, where cleanability and hygiene are critical.
Performance in Harsh Environments
Grade 316 stainless steel is widely recognised for its durability in aggressive conditions. It is commonly used in:
-
Marine and coastal environments
-
Sea-front buildings, wharves, and piers
-
Food and beverage processing facilities
-
Chemical, petrochemical, and mineral processing plants
-
Architectural components in polluted or industrial areas
It resists ordinary rusting in virtually all architectural applications, withstands most food-processing environments and is resistant to organic chemicals, dye stuffs and a wide range of inorganic chemicals.
Additional Material Benefits
Grade 316 stainless steel is often referred to as “marine grade” stainless steel due to its superior corrosion resistance. It is also virtually non-magnetic, even after cold working, unlike 304 stainless steel which can become magnetic in some conditions. This characteristic may be important in certain specialised applications.
ASSDA-Approved
Manufacturing Processes
B&R Enclosures utilises ASSDA-approved belt grinding and linishing techniques to achieve consistent surface quality and corrosion resistance. These processes ensure our enclosures can withstand prolonged exposure to chlorides, including saltwater commonly found in both coastal and inland environments worldwide.
Built to Last
The careful selection of materials, combined with superior surface finishing, results in some of the longest-lasting stainless steel industrial enclosures available. This commitment to quality not only extends product lifespan in the field but also delivers a level of performance and finish that sets B&R Enclosures apart from competitors.
