H型鋼屬于經(jīng)濟(jì)裁面型材(其它還有冷彎薄壁型鋼、壓型鋼板等)，由于截面形狀合理，它們能使鋼材更高地發(fā)揮效能，提高承裁能力。

H steel is an efficient and economical cutting section (other cold-formed thin-walled steel and profiled steel sheets). Because of the reasonable shape of the section, they can make the steel play a more effective role and improve the bearing capacity.

隨著科學(xué)技術(shù)和工業(yè)的發(fā)展，對(duì)材料提出了更高的要求，如更高的強(qiáng)度，抗高溫、高壓、低溫，耐腐蝕、磨損以及其它特殊物理、化學(xué)性能的要求，碳鋼已不能完全滿(mǎn)足要求。

With the development of science and technology and industry, the material has put forward higher requirements, such as higher strength, high temperature, high pressure, low temperature, corrosion resistance, wear and other special physical and chemical properties, carbon steel can not fully meet the requirements.

裝飾單板貼面膠合板（裝飾面板、貼面板），是將精密刨切成厚度為0.2 mm以上的薄木皮，以膠合板為基材，經(jīng)過(guò)膠粘工藝制作而成的具有單面裝飾作用的裝飾板材。

Decorative veneer veneer plywood (decorative panel, veneer) is a decorative plank which is made of a veneer with a veneer of 0.2 mm thickness and plywood as the base material.
