Fence fittings are an important part of zinc steel guardrails, which are tested by time together with the guardrails. In addition to staircase handrails, balcony guardrails, fences, shutters, anti-theft windows, etc. are all located outdoors. They should be protected from sunshine, rain, wind and dust. Especially now the air quality is falling and the acid and alkali substances in the air are increasing, which is a great test for the quality of outdoor protection products of hardware such as guardrails. Without excellent quality, it is impossible to ensure long-term use. If the ordinary zinc steel fence does not have time in anti-corrosion, it is difficult to guarantee the use time and safety.

　　室外的鋅鋼護欄大多都經過熱鍍鋅，而熱鍍鋅的益處有哪些呢？其實這個問題大家都懂一些，詳細熱度比冷鍍好在哪里還需細分一下：

　　Most of the outdoor galvanized steel guardrails are hot galvanized. What are the benefits of hot galvanizing? As a matter of fact, we all know a little about this problem. It needs to be subdivided in detail where the heat is better than that of cold plating.

　　1、熱鍍鋅處置費用低：熱浸鍍鋅防銹的費用要比其他漆料涂層的費用低。

　　1. Disposal cost of hot dip galvanizing is low: the cost of anti-rust of hot dip galvanizing is lower than that of other paint coatings.

　　2、耐久耐用：在郊區環境下，規范的熱鍍鋅防銹的厚度，可堅持50年以上而不用修補；在市區或近海區域，規范的熱鍍鋅防銹層則可堅持20年而不用修補。

　　2. Durability: In suburban environment, the standard thickness of hot-dip galvanizing rust-proof can be maintained for more than 50 years without repair; in urban or offshore areas, the standard thickness of hot-dip galvanizing rust-proof layer can be maintained for 20 years without repair.

　　3、牢靠性好：鍍鋅層與鋼材間是冶金分離，成為鋼外表的一部份，因而鍍層的耐久性較為牢靠。

　　3. Good reliability: The galvanized layer is metallurgically separated from the steel and becomes a part of the steel appearance, so the durability of the coating is more reliable.

　　4、鍍層的韌性強：鍍鋅層構成一種特別的冶金構造，這種構造能接受在運送及運用時遭到機械損傷。

　　4. Strong toughness of the coating: The galvanized layer forms a special metallurgical structure which can accept mechanical damage during transportation and operation.

　　5、全面性維護：鍍件的每一局部都能鍍上鋅，即便在凹陷處、尖角及躲藏處都能全面地遭到維護。

　　5. Overall maintenance: Every part of the plated part can be galvanized, even in the depression, sharp corner and hiding place can be fully maintained.

　　每種產品都有本人的頤養方式，每種方式都能有效的進步其壽命，更好的到達不糜費的狀況。

　　Each product has its own way of self-care, each way can effectively improve its life span, better reach the situation of no wastage.
