Our GASTRONORM are not just simple stainless steel containers

What characterizes our products is the result of choices made over the years

  • Studied and made according to UNI 631-1 standard
  • Made out of AISI 304 (1.4301) stainless steel to grant an outstanding corrosion resistance
  • AISI 304 is an austenitic steel which can be used for food contact according to Italian regulation dated 21/03/1973 and further modifications
  • They are molded out of already annealed coils, which grants the best “starting base” for corrosion resistance 
  • Made out of stainless steel with a nickel content higher than the standard value, they grant an even higher corrosion resistance 
  • Thicknesses are specifically studied in order to grant better resistance and avoid shape alterations
  • Reduced radiuses grant maximum capacity
  • They come with stacking edges to allow optimal stacking 
  • Calibrated edge flatness allow best aesthetics and bending resistance
  • Grinding operations are performed by anthropomorphic robots in order to avoid any cutting edges
  • Containers are submitted to an annealing treatment which heats them up to a temperature of 1000-1050°C, in order to completely remove alterations and tensions due to the molding process and to keep them at such a temperature for long enough a time to solute all carbons; and then to cool them down quickly enough to prevent precipitation of said carbons
  • They further undergo pickling, passivation and tumbling treatments as well, which are necessary to remove any trace of residues due to the production process, promote the formation of the passive layer, reach the requested finishing condition, according to the aesthetic requests and to further enhance corrosion resistance. Corrosion tests performed on salty vapors conditions for over 1500 hours confirm the finished containers do not get corroded at all 
  • All containers are thoroughly washed by use of super-demineralized water
  • Different customer-specific finishing can be accommodated upon request
  • PVD (Physical Vapor Deposition) or antimicrobial (ABACO JIS Z 2801/A12012) treatments available
  • Reduced surface roughness allows easy cleaning
  • Manufactured according to GMP (Good Manufacturing Practices) procedures, as stated by the European Regulation CE N. 1935/2004 issued by the European Parliament, and by the European Regulation CE N. 2023/2006
  • Containers do respect migration limits (total and specific) for Nickel, Chrome, and Manganese according to the following test parameters:
                       •             Simulating agent: acetic alcohol 3% P/V;
•             Time and temperature: 30 minutes at 100°C – repeated contact
•             Ref.: Italian regulation DM 21/03/1973 and modifications
  • Containers are manufactured according to procedures that permit full lot tracking, according to Italian regulation N. 2023/2006 GMP (Good Manufacturing Practices)
