1. Hot steel reinforcing mesh is also called hot-dip steel. It melts zinc ingot at high temperature, puts some auxiliary materials into it, and then submerges the metal structure into the steel trough. Hot steel reinforcing mesh makes the metal component attach a layer of zinc. The advantage of hot steel lies in its strong anti-corrosion ability and good adhesion and hardness of steel layer

熱鋼鋼筋網即把鋅鹽溶液通過電解，給鍍件上鍍層，一般來說不用加熱，上鋅量很少，遇到潮濕環境很容易脫落。鋼筋網是縱向鋼筋和橫向鋼筋分別以一定間距排列且成直角，全部交焊點均焊接在一起的鋼筋網片。

Hot steel reinforcing mesh is to electrolyze the zinc salt solution to coat the plated parts. Generally speaking, it does not need to be heated, and the zinc content is very small, so it is easy to fall off in wet environment. The reinforcing mesh is a kind of reinforcing mesh which is arranged at a certain distance and at right angles with all the welding joints welded together.

熱鋼是化學處理，屬于電化學反應。

Hot steel is a chemical treatment and belongs to electrochemical reaction.

冷鋼是物理處理，只是在表面刷一層鋅，所以鋅層易脫落。建筑施工中多采用熱鋼。

Cold steel is a physical treatment, just brush a layer of zinc on the surface, so the zinc layer is easy to fall off. Hot steel is often used in construction.

連續熱鋼工藝：熱鋼鋼筋網鋼材 rarr;加熱 rarr;冷卻鋼溫度 rarr;鋼 rarr;冷卻

Continuous hot steel process: hot steel mesh steel rarr; heating rarr; cooling to steel temperature rarr; steel rarr; cooling

冷鋼就是電鋼，只有10－50g/m2，其本身的耐腐蝕性比熱浸鋼相差很多。采用電鋼的相對便宜一些。

Cold steel is electrical steel, only 10-50g / m2, its corrosion resistance is much different from hot-dip steel. The price of electric steel is relatively low.

熱鋼鋼筋網是鋼體在熱浸的條件下對表面鋼，它的附著力(adhesion)很強，不容易脫落，熱鋼管雖然也出現銹蝕的現象，但在很長的周期可以滿足技術、衛生要求。

Hot steel reinforcing mesh is the surface steel of the steel body under the condition of hot-dip. Its adhesion is very strong and it is not easy to fall off. Although the hot steel pipe is rusted, it can meet the technical and sanitary requirements in a long period.

3。工藝區別

3. Process difference

工藝的區別是：熱鋼鋼筋網是將工件除油、酸洗、浸藥、烘干后浸入溶化的鋅(zinc)液里一定時間，提出來即可。

First of all, the difference of the process is that the hot steel reinforcing mesh can be extracted by immersing the workpiece in the solution of zinc (zinc) after oil removal, acid pickling, chemical soaking and drying for a certain period of time.

冷鋼也叫電鋼，是利用電解設備將工件經過除油、酸洗后放入成分為鋅(zinc)鹽的溶液中，并連接電解設備的負極；在工件的對面放置鋅板連接在電解設備的正極，接通電源，利用電流從正極向負極的定向移動，就會在工件上沉積（sedimentation)一層鋅。

Cold steel is also called electric steel. It uses electrolytic equipment to put the workpiece into zinc salt solution after oil removal and acid pickling, and connect the negative pole of the electrolytic equipment; place zinc plate on the opposite side of the workpiece to connect the positive pole of the electrolytic equipment, connect the power supply, use the current to move from the positive pole to the negative pole, and a layer of zinc will be deposited on the workpiece.

鋼成品的區別：熱鋼鋼筋網外表沒有冷鋼細膩（細致光滑或描寫、表演等細致入微)光亮，但鋅層厚度方面熱鋼是冷鋼的幾十倍。建筑鋼筋網鋼筋交叉點開焊數量不得超過整個網片交叉點總數的1%。并且任一根鋼筋上開焊點數不得超過該根鋼筋上交叉點總數的一半。鋼筋網更外邊鋼筋上的交叉點不得開焊。熱鋼鋼筋網防腐蝕(釋義:指腐爛、消失、侵蝕等)性能也是電鋼的幾十倍。

Difference of steel products: the surface of hot steel mesh is not as bright as that of cold steel, but the thickness of zinc layer is dozens of times of that of cold steel. The number of open welding at the intersection of building reinforcement mesh shall not exceed 1% of the total number of intersections of the whole mesh. And the number of open welding points on any reinforcement shall not exceed half of the total number of intersections on that reinforcement. No welding shall be carried out at the intersection of the outermost reinforcement of the fabric. The anti-corrosion performance of hot steel mesh is dozens of times of that of electric steel.

4。問題

4. Environmental issues

熱鋼鋼筋網污染物排放更少一些。

The pollutant emission of hot steel mesh is less.

熱鋼鋼筋網的污染物主要是酸洗工件的廢酸。

The main pollutant of hot steel mesh is the waste acid of pickling workpiece.

冷鋼的污染物主要包括酸洗工件的廢酸、電鍍廢液、廢鈍化液等。

The pollutants of cold steel mainly include waste acid, electroplating waste liquid, waste passivation liquid, etc.

冷鋼的污染物排放種類和數量都大大超過熱鋼。

The type and quantity of pollutant emission of cold steel are much more than that of hot steel.
