工字鋼：工字鋼鋼質(zhì)型材的一種，也稱鋼梁，是截面為工字形的長(zhǎng)條鋼材--由此得名“工字鋼”。因此又可以進(jìn)一步分成凸緣型材、多臺(tái)階型材、寬薄型材、局部特殊加工型材、不規(guī)則曲線型材、復(fù)合型材、周期斷面型材和金屬絲材等等。 工字鋼 規(guī)格及型號(hào) 其規(guī)格以腰高的毫數(shù)表示，如“工160×88×6”，即表示腰高為160毫米，腿寬為88毫米，腰厚為6毫米的工字鋼。 標(biāo)稱規(guī)格 工字鋼的規(guī)格也可用型號(hào)表示，型號(hào)表示腰高的厘米數(shù)，如工16#。

I-steel: a steel bar of I-steel, also known as steel beam, is a long steel section of the cross section, which is called "i-i-steel". The specificati and types of I-steel are represented by the number of waist height, such as "160 x 88 x 6", that is, I-bar with waist height of 160 mm, leg width of 88 mm and waist thickness of 6 mm. The specificati of the nominal size of the I-steel can also be expressed by the model, and the size of the height of the waist is centimetre, such as the 16#.

不同于普通工字型的是H型鋼的翼緣進(jìn)行了加寬，且內(nèi)、外表面通常是平行的，這樣可便于用高強(qiáng)度螺栓和其他構(gòu)件連接。其尺寸構(gòu)成合理系列，型號(hào)齊全，便于設(shè)計(jì)選用。（除了吊車梁用工字型鋼）。

Unlike the ordinary I-type, the flange of H steel is widened, and the inner and outer surfaces are usually parallel, so that it can be easily connected with high-strength bolts and other components. Its size is a reasonable series, and the model is complete, which is convenient for the design. (except for crane girder with I-type steel)

裝飾板材是所有板材的總稱，主要有：細(xì)木工板、膠合板、裝飾面板、密度板、集成材、刨花板、防火板、石膏板、PVC板、鋁扣板、鋁塑板、三維板等。

Decorative board is the general name of all board, mainly:  board, plywood, decorative panel, density board, integrated material, particleboard, fire board, plasterboard, PVC board, aluminum plate, aluminum plastic board, three-dimensional board, etc.

細(xì)木工板握螺釘力好，強(qiáng)度高，具有質(zhì)堅(jiān)、吸聲、絕熱等特點(diǎn)，而且含水率不高，在10%—13%之間，加工簡(jiǎn)便，用途為廣泛。

The woodworking board has good grip strength, high strength, strong quality, sound absorption, insulation and other characteristics, and water content is not , between 10% - 13%, easy processing, the most widely used.
