H型鋼，是一種截面面積分配更加優化、強重比更加合理的經濟斷面型材，因其斷面與英文字母“H”相同而得名。H型鋼的兩條外邊內側沒有斜度，是平直的。這使得H型鋼的焊接拼接比工字鋼操作簡單，單位重量的力學性能更好，可以節省大量的材料和施工時間。

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.

工字型鋼不論是普通型還是輕型的，由于截面尺寸均相對較高、較窄，故對截面兩個主袖的慣性矩相差較大，因此，一般僅能直接用于在其腹板平面內受彎的構件或將其組成格構式受力構件。

I-steel whether ordinary or light, because the section size are relatively high and narrow, so the moment of inertia of the main secti of the two sleeve is large, therefore, generally only can be directly used in the web plane bending member or the of lattice stress components.

型材是鐵或鋼以及具有一定強度和韌性的材料通過軋制、擠出、鑄造等工藝制成的具有一定幾何形狀的物體。這類材料具有的外觀尺寸一定，斷面呈一定形狀，具有一定的力學物理性能。標稱規格工字鋼的規格也可用型號表示，型號表示腰高的厘米數，如工16#。型材既能單獨使用也能進一步加工成其他制造品，常用于建筑結構與制造安裝。型材的材質、規格尺寸等可參照相應的國家標準。軋機結構和軋機布置形式較多。在結構形式上有二輥式軋機、三輥式軋機、孔型軋機、多輥孔型軋機、Y型軋機、45°軋機和懸臂式軋機等。

膠合板是由三層或多層一毫米左右的實木單板或薄板膠貼熱壓制成，常見的有三夾板、五夾板、九夾板和十二夾板（俗稱三合板，五厘板，九厘板，十二厘板）。

Plywood is made of three or more than one millimeter of solid wood veneer or thin plate with hot pressing. There are three splints, five splints, nine splints and twelve splints (commonly known as three plywood, five millimeter, nine millimeter, twelve millimeter).
