This 9-page document summarizes testing of steel and tower welding parts to ASTM A36 and A123 standards. Key points: - Chemical and mechanical tests were conducted on steel samples to evaluate properties like carbon content, tensile strength, and coating thickness. - Coating thickness on the steel averaged 86μm and 94μm on welding parts, meeting the minimum thickness grades required in Table 1. - The zinc coating was continuous and reasonably smooth/uniform, with allowances made for design factors. It withstood normal handling without peeling. - All test results indicated the samples passed requirements for chemical composition, tensile strength, coating properties, and appearance under the ASTM standards.

6 Coating Properties -
6.1 Coating Thickness -
Coating Thickness—The average thickness of
coating for all specimens tested shall conform to
the requirements of Table 1 for the categories and
thicknesses of the material being galvanized.
Minimum average thickness of coating for any
individual specimen is one coating grade less
than that required in Table 1. Where products
consisting of various material thicknesses or
categories are galvanized, the coating thickness
grades for each thickness range and material
category of material shall be as shown in Table 1.
In the case of orders in SI units, the values in
Table 1, shall be applicable as metric units in
micrometres. In the case of orders in inch-pound
units,the measured value shall be converted to
coating grade units by the use of Table 2. The
specification of coating thicknesses heavier than
those required by Table 1 shall be subject to
mutual agreement between the galvanizer and the
purchaser.(Fig. 2 is a graphic representation of
the sampling and specimen delineation steps, and
Fig. 3 is a graphic representation of the coating
thickness inspection steps.)
6.1.1 For articles whose surface area is greater than 160
in.2[100 000 mm2] (multi-specimen articles),
each test article in the sample must meet the
appropriate minimum average coating thickness
grade requirements of Table 1, and each
specimen coating thickness grade comprising that
overall average for each test article shall average
not less than one coating grade below that
required in Table 1.
-
6.1.2 For articles whose surface area is equal to or less
than 160 in.2 [100 000 mm2] (single-specimen
articles), the average of all test articles in the
sample must meet the appropriate minimum
average coating thickness grade requirements of
Table 1, and for each test article, its specimen
coating thickness shall be not less than one
Steel :86μm
tower welding parts:94μm
P

6. No: SCC2015-1714A-1

coating grade below that required in Table 1.
6.1.3 No individual measurement, or cluster of
measurements at the same general location, on a
test specimen shall be cause for rejection under
the coating thickness requirements of this
specification provided that when those
measurements are averaged with the other
dispersed measurements to determine the
specimen coating thickness grade for that
specimen, the requirements of 6.1.1 or 6.1.2, as
appropriate are met.
-
6.2 Finish P
The coating shall be continuous (except as
provided below), and as reasonably smooth and
uniform in thickness as the weight, size, shape of
the item, and necessary handling of the item
during the dipping and draining operations at the
galvanizing kettle will permit. Except for local
excess coating thickness which would interfere
with the use of the product, or make it dangerous
to handle (edge tears or spikes),rejection for
nonuniform coating shall be made only for
plainly visible excess coating not related to
design factors such as holes, joints, or special
drainage problems (see Note 6).
6.2.1 Each area subject to renovation shall be 1 in. [25
mm]or less in its narrowest dimension.
P
6.2.2 The total area subject to renovation on each
article shall be no more than 1⁄2 of 1 % of the
accessible surface area to be coated on that
article, or 36 in.2 per short ton [256 cm2 per
metric ton] of piece weight, whichever is less.
P
6.2.3 The thickness of renovation shall be that required
by the thickness grade for the appropriate
material category and thickness range in Table 1
in accordance with the requirements of 6.1,
except that for renovation using zinc paints, the
thickness of renovation shall be 50 % higher than
that required by Table 1, but not greater than 4.0
mils.
P
6.2.4 When areas requiring renovation exceed the
criteria previously provided, or are inaccessible
for repair, the coating shall be rejected.

6.3 Threaded Components in Assemblies P
The zinc coating on external threads shall not be
subjected to a cutting, rolling,or finishing tool
operation, unless specifically authorized by the
purchaser. Internal threads are not prohibited
from being tapped or retapped after galvanizing.
Coatings shall conform to the requirements of
Specification A153/A153M.
6.4 Appearance P
Upon shipment from the galvanizing facility,
galvanized articles shall be free from uncoated
areas,blisters, flux deposits, and gross dross
inclusions. Lumps,projections, globules, or heavy
deposits of zinc which will interfere with the
intended use of the material will not be permitted.
Plain holes of 1⁄2-in. [12.5-mm] diameter or more
shall be clean and reasonably free from excess
zinc. Marks in the zinc coating caused by tongs or
other items used in handling the article during the
galvanizing operation shall not be cause for
rejection unless such marks have exposed the
base metal and the bare metal areas exceed
allowable maximums from 6.2.1 and 6.2.2. The
pieces shall be handled so that after galvanizing
they will not freeze together on cooling.
6.5 Adherence P
The zinc coating shall withstand handling
consistent with the nature and thickness of the
coating and the normal use of the article, without
peeling or flaking.
