H型鋼是一種斷面力學(xué)性能較工字鋼優(yōu)良的經(jīng)濟(jì)型斷面鋼材，因其斷面的形狀與英文字母“H”相同而得名。熱軋H型鋼的翼緣比工字鋼寬、側(cè)向剛度大、抗彎能力強(qiáng)。同等規(guī)格下H型鋼理重較工字鋼輕。

H steel is a kind of economical section steel with better section mechanical properties than that of I-steel. Because the shape of the section is the same as that of the English letter "H". The flange of hot rolled H steel is wider than that of I-steel, large lateral stiffness and strong bending resistance. Under the same specification, the weight of H steel is lighter than that of I-steel.

厚鋼板的鋼種大體上和薄鋼板相同。在品各方面，除了橋梁鋼板、鍋爐鋼板、汽車制造鋼板、壓力容器鋼板和多層高壓容器鋼板等品種純屬厚板外，有些品種的鋼板如汽車大梁鋼板（厚2.5~10毫米）

The steel of a thick steel plate is roughly the same as that of a thin steel plate.

細(xì)木工板比實(shí)木板材穩(wěn)定性強(qiáng)，但怕潮濕，施工中應(yīng)注意避免用在廚衛(wèi)。

細(xì)木工板的加工工藝分機(jī)拼和手拼兩種，手工拼制是用人工將木條鑲?cè)電A板中，木條受到的擠壓力差，不能據(jù)切加工，只適宜做部分裝修的子項(xiàng)目，如做實(shí)木地板的墊層毛板等。

Blockboard is more stable than solid wood, but it is afraid of humidity. In ctruction, it should be avoided in kitchen and toilet.

The processing technology of the carpenter board is divided into two kinds. The manual spelling is to insert the wooden bar into the splint, the squeezing pressure of the wooden bar is poor, it can not be cut by cutting, it is only suitable for the subproject of partial decoration, such as the cushion coat of the solid wood floor.

特性:裝飾面板一般用于清油裝飾。表層薄而板是名貴木種，紋理天然、華美。基材一般是膠合板，性能穩(wěn)定可靠。

Features: decorative panels are generally used for oil decoration. The surface is thin and board is a valuable wood species with natural and beautiful texture. The base material is generally plywood, the performance is stable and reliable.
