Finishes
NILES EXPANDED METALS AND GRATINGS
are available in your choice of finishes. Greenhouse benches, patio
furniture, utility trailers and playground equipment are among
the many places that you will find expanded metal mesh with a finished
or coated surface.
CLEANING is the first step in a finishing process. NILES
EXPANDED METALS AND GRATINGS are lightly coated with a water-based
lubricant and therefore will require cleaning prior to finishing.
Most finishing services will include cleaning the material prior
to processing. Depending on your situation and material type,
various cleaning methods are available from mild detergents
to sandblasting.
GALVANIZING is a popular and common form of finishing.
ONE OF THE MOST IMPORTANT THINGS TO
KNOW IS ALL FORMS ARE NOT ALIKE. The galvanized finish
should cover the entire surface of the material and any exposed or
unfinished surfaces should be considered unacceptable. The coating
thickness is to ASTM-123 (latest revision) standards. The sheets are
dipped in molten zinc and allowed to dry. This may result in a finish
with a rough and uneven appearance.
Due to the temperatures that are required to melt the zinc,
warping and / or distortion may occur, especially in materials
lighter than 18 gauge.
In addition, patterns with openings smaller than 1/2 inch are
not recommended for galvanizing because the openings may become
filled.
Galvanizing Services
ANODIZING is used primarily on aluminum; however, certain
alloys do not lend themselves to the anodizing process as well
as others. This type of finish is electrochemically applied
in various thicknesses and offers a wide range of color choices.
Coating thickness varies according to the application. The finished
surface is smooth and uniform in appearance.
IN ADDITION to the finishes listed here, NILES also offers
primer, painted, powder, plastic and porcelain coated options.
