H型鋼，是一種截面面積分配更加優(yōu)化、強(qiáng)重比更加合理的經(jīng)濟(jì)斷面型材，因其斷面與英文字母“H”相同而得名。H型鋼的兩條外邊內(nèi)側(cè)沒有斜度，是平直的。這使得H型鋼的焊接拼接比工字鋼操作簡單，單位重量的力學(xué)性能更好，可以節(jié)省大量的材料和施工時(shí)間。

H steel is a more efficient and economical section with high section area distribution, because its section is the same as the English letter "H". The two sides of the H type steel have no slope inside the inner side, and they are straight. This makes the welding and splicing of H steel simpler than I-steel, better mechanical properties per unit weight, and can save a lot of material and ctruction time.

槽鋼分普通槽鋼和輕型槽鋼。熱軋普通槽鋼的規(guī)格為5-40#。經(jīng)供需雙方協(xié)議供應(yīng)的熱軋變通槽鋼規(guī)格為6.5-30#。槽鋼主要用于建筑結(jié)構(gòu)、車輛制造、其它工業(yè)結(jié)構(gòu)和固定盤柜等，槽鋼還常常和工字鋼配合使用。

Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot rolled ordinary channel steel is 5-40#. The specification of hot rolled and variable channel steel supplied by both suppliers and suppliers is 6.5-30#. Channel steel is mainly used in building structure, vehicle manufacturing, other industrial structure and fixed disk cabinet, and channel steel is often used in conjunction with I-steel.

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.
