The Sendzimir hot-dip galvanizing process creates an aesthetic appearance that’s specific to each manufacturer. The appearance is generally quite homogeneous, although there can be variations due to processes, humidity and temperature of the environments where the products are made.
Over time, primarily to comply with increasingly stringent environmental safety standards, new processes have greatly reduced the size of the galvanising “sheets”, so much so that only so-called “micro-spangled” sheets are available for high-quality products on the market today.
Even though quality sheets are all “micro-spangled”, their appearance can differ, especially in terms of shine. These differences become immediately obvious when panels made from sheets of different origins are laid in large rooms.
To avoid this problem and guarantee maximum visual homogeneity, JVP has been using only sheets with a B finish, better known as skinpassed sheets, on the upper visible surface of the panels for some time.
Skinpassing involves calendering the sheets, to “flatten” the galvanizing “micro-spangles” and guarantee an appearance that’s at most a bit opaque but at least very consistent, even between different producers.
While there might still be some slight differences, their frequency and noticeability is very limited, so that they can be considered to meet the strictest standards of homogeneity. In any case, any variations in appearance do not affect product performance in any way.
