什么是热镀锌？

What is hot-dip galvanized?

热镀锌也叫热浸锌和热浸镀锌:是一种有效的金属防腐方式，主要用于各行业的金属结构设施上。是将除锈后的钢件浸入500℃左右融化的锌液中，使钢构件表面附着锌层，从而起到防腐的目的。

Hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: it is an effective metal anticorrosion method, mainly used in the metal structure facilities in various industries.It is to rust the steel parts into about 500℃ of melted zinc liquid, so that the surface of the steel members attached to the zinc layer, so as to play the purpose of anticorrosion.

那么，扁铁和扁钢一样吗？

So, is flat iron the same as flat steel?

扁铁是铁，是A3，普通的铁，不能淬火烧硬，扁钢是钢材，是含有碳元素的铁，钢可以做高档的东西，需就淬火热处理后有一点硬度。

Flat iron is iron, is A3, ordinary iron, can not be hardened burning, flat steel is steel, is the iron containing carbon elements, steel can do high-grade things, need to quench heat treatment after a little hardness.

扁钢是一种截面为长方形并稍带钝边的钢材。扁铁可以用做成材，也可以作为坯料使用，应用十分广泛。

Flat steel is a kind of steel with a rectangular section and a slightly blunt edge.Flat iron can be used as a material, or as a blank material, and it is widely used.

两者不同的是扁钢的基材是钢（铁中含碳），而扁铁的基材是铁。

The difference is that the base of flat steel is steel (iron contains carbon), while the base of flat iron is iron.

镀锌扁铁作为成材可用于制箍铁、工具及机械零件，建筑上用作房架结构件、扶梯，有良好的防腐防锈功能，常用于防雷接地的导体。

Galvanized flat iron as a material can be used for hoop iron, tools and mechanical parts, used as building structure parts, escalator, has a good anti-corrosion and rust prevention function, often used for lightning protection grounding conductor.

镀锌扁钢是宽12-300mm、厚4-60mm，可以是成品钢材，也可以做焊管的坯料和叠轧薄板用的薄板坯，形状同镀锌扁铁一样，两者不同的是基材。

Galvanized flat steel is 12-300mm wide, 4-60mm thick, can be finished steel, can also be welded pipe billet and rolling sheet thin slab, the same shape as galvanized flat iron, the two are different from the substrate.

镀锌扁钢采用先进的热浸镀锌工艺生产，产品表面光华，无漏镀，无疤点，锌层均匀，附着能力强，材质符合国家标准,具有一定的抗腐蚀能力,可适用于多种行业。

Galvanized flat steel adopts advanced hot dip galvanizing process production, product surface light, no leakage plating, no scar point, zinc layer uniform, strong attachment ability, material in line with national standards, with a certain corrosion resistance, can be applicable to a variety of industries.

镀锌扁钢的用途

Use of galvanized flat steel

一、镀锌扁钢可以用于制作构件、扶梯桥梁以及栅栏等。

镀锌扁钢具有很好的强度，并且镀锌扁钢的表面相比于其他钢材是比较光洁的。另外就是镀锌扁钢的厚度规格的档距非常紧密，这也就决定了镀锌扁钢非常的适合焊接。值得一提的是，扁钢的承载重量较大。而构件、扶梯以及栅栏等物品在生产的过程中，焊接是必不可少的一个加工工艺。同时，此类物件还必须要求钢材的表面要光滑，能够承载一定量大重物。而扁钢的某些特点恰恰完全满足要求。这样就使得镀锌扁钢成为了加工制作构件、扶梯以及栅栏等物品的原材料。

First, galvanized flat steel can be used to make components, escalator Bridges and fences.

Galvanized flat steel has a very good strength, and the surface of galvanized flat steel is relatively smooth compared to other steels.In addition, the thickness of the galvanized flat steel specification spacing is very close, which also determines that the galvanized flat steel is very suitable for welding.It is worth mentioning that the bearing weight of flat steel is larger.In the process of production, welding is an essential processing process for components, escalators and fences.At the same time, such objects must also require the surface of the steel to be smooth and can carry a certain amount of heavy objects.And some characteristics of flat steel just fully meet the requirements.This makes galvanized flat steel a raw material for processing components, escalators and fences.

二、镀锌扁钢可以被用作焊钢坯料和叠轧薄板的板坯。

镀锌扁钢是一种界面为矩形的钢材，可以被看做是长条钢板的一部分。而这也就使得镀锌扁钢可以被加工制作成为一颗面积较大的钢板。

Two, galvanized flat steel can be used as welding billet and overlapping rolling sheet slab.

Galvanized flat steel is a rectangular steel interface that can be regarded as part of a long steel plate.This also makes the galvanized flat steel can be processed into a large steel plate.

三、镀锌扁钢可以被制作成为箍铁材料。扁钢是一种长条状的钢材，其厚度和宽度的规格非常齐全。还有就是扁钢的柔韧性和比较好，是完全可以被用作加工制作箍铁材料。

Three, galvanized flat steel can be made into the hoop iron material.Flat steel is a long strip of steel with a very complete range of thickness and width specifications.There is the flexibility and better of flat steel, is completely used as processing hoop iron material.

镀锌扁钢作为一种应用广泛的钢材，是钢结构制造、机械制造、汽车工业、矿山机械、起重机械、建筑业等行业不可缺少的原材料。

Galvanized flat steel, as a widely used steel, is an indispensable raw material for steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, lifting machinery, construction industry and other industries.

在一般的环境里，镀锌扁钢的热镀锌防锈厚度可保持50年以上而不必修补；在市区或近海区域，镀锌防锈层则可保持20年而不必修补；镀锌扁钢的镀锌层与钢材间是冶金结合，成为钢表面的一部份，因此镀锌扁钢的镀层的持久性较为可靠；镀层的韧性强，镀锌层形成一种特别的冶金结构，镀锌扁钢的这种工艺，能较强的承受在运送及使用时受到的机械损伤。

In general environment, the hot galvanized antirust thickness of galvanized flat steel for over 50 years without repair; in urban or offshore areas, for 20 years; the galvanized layer of galvanized flat steel is combined with metallurgy as a part of steel surface, so the durability of galvanized flat steel is reliable, and the galvanized layer forms a special metallurgical structure. This process of galvanized flat steel can withstand mechanical damage during transportation and use.
