目前，冰箱所用的側(cè)板、后板、后底板大部分為金屬板材，該金屬板包括金屬噴涂板、鍍鋅板、鍍鋁鋅板等，另外還有一小部分的后板、后底板為紙板或中空板，也稱鈣塑板或瓦楞紙板。其中，金屬板材的強(qiáng)度高、易成型，但價(jià)格較高。

At present, the refrigerator side board, back board, rear bottom board is mostly metal board, the metal plate includes metal spray board, galvanized sheet, there are a small part of the back plate, back bottom plate is cardboard or hollow board, also called calcium plastic board or corrugated board. Among them, the strength of the metal plate is high, easy to form, but the price is higher.

市面上質(zhì)量好的的冰箱，底板與背板采用鍍鋅鋼板制成，耐高溫耐腐蝕，防火防沖擊，同時(shí)又具有良好的保溫性能，真材實(shí)料。

The refrigerator with good quality on the market, the bottom and back plate are made of galvanized steel plate, high temperature and corrosion resistance, fire prevention, at the same time has good insulation performance, real material.

冰箱底板一直使用的是厚度0.3mm的鍍鋅鋼板，這是因?yàn)?/font>鍍鋅板有良好的抗腐蝕能力。冰箱完成發(fā)泡過程之后，鍍鋅鋼板的主要作用就是防止外界水蒸氣等因素引發(fā)鋼板生銹，防止內(nèi)部的發(fā)泡料腐蝕鋼板，據(jù)對(duì)冰箱各零部件所作的匹配可靠性調(diào)查，冰箱的使用壽命平均為10年左右，而鍍鋅鋼板在鍍鋅量為350克/平方米（單面）時(shí)，在室外的壽命（生紅銹），約為15~18年，冰箱作為家庭內(nèi)置消費(fèi)品，它的使用環(huán)境遠(yuǎn)遠(yuǎn)優(yōu)越于室外，類比可知，同樣的鍍鋅鋼板使用在冰箱上，壽命應(yīng)該高于18年，遠(yuǎn)高于冰箱的整體使用壽命。

The refrigerator floor has been used in the thickness of 0.3mm galvanized steel plate, because the galvanized plate has good corrosion resistance. Refrigerator after the foaming process, galvanized steel plate's main role is to prevent external factors such as water steam steel rust, prevent internal foam corrosion steel, according to the matching reliability survey, the service life of the refrigerator on average 10 years, and galvanized steel plate in galvanized amount of 350 grams / square meters (single side), in the outdoor life (red rust), about 15~18 years, the refrigerator as a family built-in consumer goods, its use environment is far superior to outdoor, analogy, the same galvanized steel plate used in the refrigerator, life should be higher than 18 years, Far higher than the overall service life of the refrigerator.
