Hot dip galvanized metal fence _ yup _ St. galvanizing spray fence manufacturers offer by St Ye metals. Hot dip galvanized metal fence _ Ye holy hot dip galvanized fence manufacturers _ after Linqu St. Ye metallwarenfabrik (www.shengyehl.com) 2014 年 launched a new upgrade the performance of hot-dip galvanized fence has the following advantages. Thick cover layer coating hierarchical, near the inner workpiece, the workpiece component chemical composition containing up to; close to the surface of the outer layer of hot dip galvanized fence, metal plating chemical composition containing at most. An intermediate layer between the inner and outer layer of the alloy. Alloy layer containing a small amount due to the workpiece metal and trace inclusion, it is more brittle hot dip galvanized fence maintenance, mechanical properties of the coating is very bad, its thickness should be controlled. Hydrochloric acid descaling method is hot dip galvanized guardrail business uses. Therefore, hydrochloric acid is the raw material is widely used. Mass fraction of the regular control in the range of 5% to 15%. The lower the mass fraction of the acid, the longer pickling of hot-dip galvanized fence needed. Typically temperature thermal spray pickling galvanized fence prices, pickling speed impact. In addition, when pickling hot dip galvanized hot dip galvanized guardrail fence manufacturers, iron deposition in the tank will continue. When ferric reached 150-200g / L, although the tank contains a certain quality of acid, but the pickling speed greatly slowed down. In the case without the descaling agent, usually disposed of in its entirety.
