Both specifications require that the exposed area be less than an inch in its narrowest dimension. Both specifications require the use of a knife csx to determine proper coating adherence. But G has its own test procedures for the weakening of the base layer, A refers to the most complete guide of the ASTM A standard, which gives the details of a bending test.
Recent reports have shown that much thicker coatings gg164 these minimum requirements are not feasible on these materials. However, due to financial considerations, CSA G has not csaa updated since and there appears to be no intention to do so.
Differences Between ASTM A123 and CSA G164
ASTM A is listed as the standard for renovation by each specification. The first major difference between the two specifications comes when section 3.
Table 1 of ASTM A has requirements for structural forms, strips and bars, plates, pipes and tubes, wires and rebar. However, there are some competing specifications that get attention when cas end user asks a galvanizer to use them. Both standards also cite ASTM B6 as a standard to which the zinc used in the galvanizing bath must conform.
The procedure includes the g1644 to choose the number of samples depending on the number of parts in the lot and the length and size of the parts. It is considered the standard of the hot-dip galvanizing industry in North America. ASTM A also declares, in addition to the 0. ASTM A is listed as the standard for repair for each specification.
However, G gives its own procedures for testing for embrittlement of the base coating while A references a complete guide of ASTM A which details a bend test. Some slightly different language exists ccsa the two regarding piping csz continuous galvanizing, but when read carefully, the same information is being stated in the scope xsa each specification.
For, example, each specification uses a table to describe minimum coating thickness standards on galvanized steel, but the minimum requirements and materials listed are quite different. Both standards also cite that ASTM B6 is a standard that specifies that the zinc used in the galvanizing bath must be compliant.
It has lost relevancy in the market and is seldom used. Few conditions are given by G regarding the appearance of the zinc coating.
This leads to less confusion during the galvanizing process and creates a complete specification. The two specifications also contain a minor difference regarding the renovation of areas left uncoated during the galvanizing process. Also, A has no requirements as to the minimum coating thickness on threaded fasteners and items, but refers to ASTM A for these requirements.
However, there are some competing specifications that are worthy of consideration when an end user requests that the galvanizer use them. On the other hand, the A only requires that the average measurement of the thickness of the coating meet the minimum coating thickness required by Table 1, with the sample average having a coating less than that required in Table 1.
ASTM A also holds a few more requirements regarding the finish of the coating. However, the information presented here may adequately describe some of the major differences between the two. Each specification standardizes the coating thicknessfinish, appearance, and adherence of a hot-dip galvanized coating.
The practice behind each one of these methods varies from one specification to the next, but the most notable differences are that of the magnetic and electronic thickness gauge measurements. New information and research are constantly taken into account when updates are made to ASTM A; the last update was in A, on the other hand, only requires the average coating thickness measurement meet the minimum coating thickness required by Table 1, with the average of one specimen being one coating grade below that required in Table 1.
New information and research are constantly being considered when updates are made to ASTM A; the last such update occurring in Again, these two specifications are similar, but have some very important differences; especially in regards to the specified coating properties. Is CSA G still a valid specification? The sampling procedure laid out in G for fsa the coating thickness has some very general and relaxed guidelines.

But due to financial considerations, CSA G has not been updated since and there seem to be no plans to do so. Total average equal to the requirement for the minimum coating thickness with the thicknesses of all samples greater than a coating grade less than in Table 1. The most notable difference here is in regard to the minimum coating thickness required by A for pipe and tubing as well as for strip and bar.
The material provided herein has been developed to provide accurate and authoritative information about after-fabrication hot-dip galvanized steel.
While this standard is similar to ASTM A in scope and purpose, there are many differences between the two.
Differences Between ASTM A and… | American Galvanizer’s Association
The most significant difference here is with regard to the minimum coating thickness required by the A for pipes and tubes and for flats and bars. January 29, Authored by Daniel Barlow. However, the information presented here can csz describe some of the key differences between the two.
