鍍鋅鋼格板Galvanized steel grating（）

鍍鋅鋼格板就是鋼格板生產(chǎn)出來(lái)以后，進(jìn)行的防銹處理。有熱鍍鋅鋼格板和電鍍鋅鋼格板2種。鍍鋅鋼格板具有通風(fēng)透光、防滑，承載力強(qiáng)，美觀耐用，易于清掃，安裝簡(jiǎn)便等優(yōu)點(diǎn)。熱鍍鋅標(biāo)準(zhǔn)為：GB/T 13912-2002 《鋼鐵制件熱鍍鋅技術(shù)要求及實(shí)驗(yàn)方法》鋼格板作為一種新材料、新產(chǎn)品正得到日益廣泛的應(yīng)用，其較多的優(yōu)越性能及良好的性能價(jià)格比顯示了其應(yīng)用的前景。

Galvanized steel grating is the anti-rust treatment after the steel grating is produced. There are two kinds of hot-dip galvanized steel grating and electro-galvanized steel grating. Galvanized steel grating has the advantages of ventilation, light transmission, anti-skid, strong bearing capacity, beautiful and durable, easy to clean and easy to install. The hot-dip galvanizing standard is GB/T 13912-2002 "Technical Requirements and Test Methods for Hot Dip Galvanizing of Iron and Steel Products". As a new material and new product, steel grating is being increasingly widely used. Its many superior properties and good performance-price ratio show its application prospects.

在冶金、礦山、石油、電力與工業(yè)領(lǐng)域以及一些民用領(lǐng)域中，鋼格板作為一種新型建材正得到日益廣泛的應(yīng)用。所謂新材料，其實(shí)在國(guó)外已有幾十年以上的歷史，不過(guò)在中國(guó)得到廣泛應(yīng)用也只是近10年的事。但就象鋁合金門窗一樣，與傳統(tǒng)材料相比，人們習(xí)慣上還是將其稱作新材料。

In the fields of metallurgy, mining, petroleum, electric power and industry, as well as some civil fields, steel grating is being increasingly widely used as a new type of building material. The so-called new material has a history of more than decades abroad, but it has only been nearly 10 years since it was widely used in China. But like aluminum alloy doors and windows, pared with traditional materials, people still call them new materials.

我們常說(shuō)的鍍鋅鋼格板有兩種：注意區(qū)分

熱鍍鋅----又稱為熱浸鍍鋅，他是在高溫下把鋅錠融化，在放入一些輔助材料，然后把金屬結(jié)構(gòu)件浸入鍍鋅槽中，使金屬構(gòu)件上附著一層鋅層。熱鍍鋅的優(yōu)點(diǎn)在于他的防腐能力強(qiáng)，鍍鋅層的附著力和硬度較好。產(chǎn)品鍍鋅后重量有所增加，我們常說(shuō)的上鋅量，也主要是針對(duì)熱鍍鋅來(lái)說(shuō)的。

“冷鍍”----“電鍍”，即把鋅鹽溶液通過(guò)電解，使鐵離子和鋅離子進(jìn)行置換反映，一般來(lái)說(shuō)不用加熱，上鋅量很少，遇到潮濕環(huán)境很容易生銹。

There are two kinds of galvanized steel grating we often say: pay attention to distinguish

Hot galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, add some auxiliary materials, and then immerse the metal structure into the galvanizing bath, so that a layer of zinc is attached to the metal ponents. The advantages of hot-dip galvanizing lie in its strong corrosion resistance and good adhesion and hardness of the zinc coating. The weight of the product has increased after galvanizing. The amount of zinc we often say is mainly for hot galvanizing.

"Cold plating" - "electroplating", that is to say, the zinc salt solution is electrolyzed to make iron ions and zinc ions replace and reflect. Generally speaking, there is no need to heat, and the amount of zinc is very small. It is easy to rust in wet environment.

鋼格板價(jià)格計(jì)算公式 [1]

鋼格板的重量是指經(jīng)過(guò)包邊和表面處理（非表面處理的除外）后的理論重量。由于包邊、開(kāi)孔和切口的不同，實(shí)際重量與理論重量會(huì)出現(xiàn)差異。在工業(yè)平臺(tái)鋼格板自重計(jì)算及鋼格板交付結(jié)算中，統(tǒng)一以理論重量為計(jì)算依據(jù)。對(duì)于長(zhǎng)度小于1米的鋼格板例如溝蓋板或者需要作特殊包邊的鋼格板，由于包邊板的增加，重量會(huì)隨著增加。用扁鋼包邊，正辰鋼格板長(zhǎng)度不小于1米時(shí)，按下面公式計(jì)算鋼格板理論重量： Wt=(b1t1N1+b2t2N2+2b3t3)ρµ×10-6………………（1）式中: Wt—鋼格板重量，單位為千克每平方米（kg/m2）； t1—承載扁鋼寬度，單位為毫米（mm）； b1—承載扁鋼厚度，單位為毫米（mm）； N1—每米鋼格板中承載扁鋼條數(shù)； t2—橫桿寬度，單位為毫米（mm）； b2—橫桿厚度，單位為毫米（mm）； N2—每米鋼格板中橫桿條數(shù)； t3—包邊扁鋼寬度，單位為毫米（mm）； b3--包邊扁鋼厚度，單位為毫米（mm）； ρ—材料密度，單位為千克每立方米（kg/m3）；鋼材密度按7850kg/m3計(jì)算； µ--表面處理增重系數(shù)；熱浸鋅增重按1.06計(jì)算.

Calculation formula of steel grating price [1] The weight of steel grating refers to the theoretical weight after edging and surface treatment (excluding non-surface treatment). Due to the difference of binding, opening and cutting, the actual weight and theoretical weight will differ. In the calculation of the dead weight of the steel grating of the industrial platform and the delivery and settlement of the steel grating, the theoretical weight is taken as the calculation basis. For steel grating with length less than 1m, such as trench cover plate or steel grating requiring special edging, the weight will increase with the increase of edging plate. The theoretical weight of steel grating shall be calculated according to the following formula: Wt=(b1t1N1+b2t2N2+2b3t3) ρ& micro; × 10-6.............................. (1): Wt - weight of steel grating, unit: kg/m2; T1 - width of bearing flat steel, unit: mm; B1 - thickness of bearing flat steel, unit: mm; N1 - number of bearing flat steel bars per meter of steel grating; T2 - cross bar width, unit: mm; B2 - cross bar thickness, unit: mm; N2 - number of cross bars in steel grating per meter; T3 - width of wrapped flat steel, unit: mm; B3 -- thickness of the wrapped flat steel, unit: mm; ρ— Material density, in kg/m3; The steel density is calculated as 7850kg/m3& micro;-- Weight gain coefficient of surface treatment; The weight gain of hot-dip galvanizing is calculated as 1.06

Nowadays, steel grating is used more and more widely in our daily life, and then hot-dip galvanized steel grating is also used in the actual process. However, it is particularly important to distinguish the true and false of hot-dip galvanized steel grating.

(1) Center spacing of flat steel of hot-dip galvanized steel grating: distinguished by series: series 1 is 30mm; Series 2 is 40mm; Series 3 is 60mm.

(2) Center spacing of cross bars of hot-dip galvanized steel grating: 100mm for series 1 and 50mm for series 2. Other specifications can be customized.

(3) Hot dip galvanized steel grating flat steel: Q235A or stainless steel, with mon plane type, anti-slip tooth type and section I type. Common specifications include 20 * 5, 25 * 5, 25 * 3, 32 * 5, 32 * 5, 40 * 5, 40 * 3, 50 * 5, 65 * 5, 75 * 6, 100 * 8, 100 * 10, etc.

(4) Hot dip galvanized steel grating cross bar: round steel, twisted square steel, square steel or hexagonal steel made of Q235A or 304 stainless steel. Twisted square steel is drawn and twisted by the square die in the coil, and its mon specifications are 5 * 5, 6 * 6, 8 * 8mm, etc. These are the four characteristics that distinguish the true and false hot-dip galvanized steel grating.
