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”。 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。型材按斷面尺寸可分為大型、中型和小型型材，其劃分常以它們分別適合在大型、中型和小型軋機(jī)上軋制來(lái)分類。 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#.

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。
