The weight of coating per unit area thus determined is converted to equivalent coating thickness values according to Table 2 rounding up or down as appropriate. NOTE 3—The galvanizer may choose to add trace amounts of certain elements for example, aluminum, nickel, and tin to the zinc bath to help in the processing of certain reactive steels or to enhance the cosmetic appearance of the?

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. Except for local excess coating thickness which a38 interfere with the use of the product, or make it dangerous to handle edge tears or spikesrejection for nonuniform coating shall be made only for plainly visible excess coating not related to design factors such as holes, joints, ast special drainage problems see Note 6.

NOTE 7—Items sstm are prepared for galvanizing by abrasive cleaning will generally develop a thicker coating with a moderately rougher surface. To get started, a836 on the standard list button in the menu bar. The sample consists of one or more test articles. In the case of orders in SI units, such shall be stated to the galvanizer when the order is placed. In the case of any such article containing more than one material category or steel thickness range as delineated in Table 1, that article will contain more than one specimen see Fig.

Such inaccessible areas, for example, would be the internal surfaces of certain tanks, poles, pipes, tubes, and so forth. For magnetic thickness measurements, specimen excludes any area of the surface which is subject to processes such as? This new sample shall be measured using magnetic thickness gages which have been calibrated for accuracy against reference material thickness standards.

ASTM Standard List: Coated Steels

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. In this case, the minimum number of specimens from w386 lot shall be as follows: They do not address the matter of measured coating thickness variations that can be encountered because of different steels or different thicknesses of a given steel being used in an assembly.

Therefore, some articles may have a coating grade at or close to the minimum requirement shown in Table 1. Some higher-than-standard thicknesses may be impractical or unattainable.
