"low-zinc absorption" wire and its reasoning:
What's semi-killed steel or aluminum-killed steel?
Semi-killed steel is with less silicon because, from its name, they are not killed with silicon.
The current wire rod we use is of Q195 low-carbon steel & killed steel by default.
To have the benefit of reducing the zinc pickup by the wire further, the wire is better to be changed into semi-killed steel. As a result, the finished wire will have lesser zinc pickup. It is known that silicon level in the range of 0.05% to 0.15% is known to cause high zinc pickup.
What wire rods to use that makes a difference?
In short, Q195B (notice the denominator B) is the appropriate wire rod to use, and this is available infrequently, not your normal garden-variety grade. The price per ton fetch a premium over the Q195Z, and this premium is a small one. The premium is also due to its scarcity. *Q195 by default is Q195Z or Q195TZ, thus not shown. Other properties are the same.
Point of difference:
Apart from the normal ones, we have semi-killed steel wire in the order book.
This is our point of difference. It is a unpretentious product made just for the HDG industry.

Glossary list
Annealing: commonly involves heating the material to a temperature near or below the lower critical temperature, and holding it at that temperature for a sufficient period of time, followed by slow cooling. the process softened the steel
Deoxidizing Methods are denoted by three signs: (F)means rimming, (B)means semi-killed, (Z) means killed, and (TZ)means special killed.
Killed Steel/Aluminum-Killed Steel: steel treated with a strong deoxidizing agent such as silicon or aluminum in order to reduce the oxygen content to such a level that no reaction occurs between carbon and oxygen during solidification, more silicons.
Low carbon steel wire rods- (encompass grades of steel to 0.15 percent maximum carbon content.
Non-reactive steels: ither less than 0.04% or between 0.15% and 0.25%an be expected to form thicker than average zinc coatings.
