FASTENERS
-
Specifications for fasteners should clearly state "that the fastener coating should conform to BS 7371: Part 6 : 1998". Merely to specify 'galvanized' is open to misinterpretation and zinc electroplated, mechanically plated or sherardized components, which provide less protection, may be supplied. For further information please refer to Joining Galvanized Steel.
LEAD TIMES
-
Provided reasonable notice is given, most articles can be galvanized
and returned to the fabricator within a week. A typical turn-around,
depending on size of the order, is three days. Galvanized bolts and
nuts are now widely stocked but it is advisable that orders for
galvanized fasteners should be placed as early as possible.

APPEARANCE
-
Galvanizing is primarily used to protect steelwork against corrosion.
In cases where appearance and smoothness are particularly important,
the galvanizer should be consulted at an early stage.
DUPLEX COATINGS
-
The use of paint or powder coatings over a galvanized coating may be used for aesthetics or for additional protection.
