Materials That We Use
While building our product, as designers, we are forced to balance cost, clean-ability, durability and aesthetics. Although we use painted steel when requested, we find that it is typically not cost effective for our high quality product. The cost differential between 304 stainless steel and mild powder coated steel is actually minimal as most of the cost is typically in the labor of making the piece. Mild steel will eventually chip and rust as well.
The standards for our industries are 304 stainless steel and 316 stainless steel.
Typically 304 is the less expensive of the two. It has a slightly different alloy composition than 316 which makes it more it more susceptible to corrosion. Well kept 304 will last a lifetime and look great doing it. So for more of our customers this is sufficient and it offers a great cost value proposition.
316 Stainless is more resistant to solutions such as sulfuric acid, chlorides, bromides, iodides and fatty acids. Sometimes our clients will specify 316 because during the manufacture of certain pharmaceuticals, stainless steels containing molybdenum are required in order to avoid excessive metallic contamination.
Corian is the brand name for a solid surface material created by DuPont. It is composed of acrylic polymer and alumina trihydrate (ATH). This allows Torvan to create more organic shapes that suit the design intent of the lab or hospital. The beautiful colors available allow a less clinical feel that metal, will still helping prevent infection.
Corian is manufactured in three thicknesses: 6 millimetres (0.24 in), 12 millimetres (0.47 in), and 19 millimetres (0.75 in). Cross-section cuts show consistent color and particulate patterning evenly distributed throughout the material. Nicks and scratches can be buffed out with a Scotch-Brite pad or orbital sander. In the fabrication process, joints can be made invisible by joining the relevant pieces with Corian's own color-matched two-part acrylic epoxy. The pieces are clamped tightly together in order to express any excess adhesive. After the adhesive dries, the area is sanded and polished to create a seamless joint.
