H型鋼的翼緣都是等厚度的，有軋制截面，也有由3塊板焊接組成的組合截面。工字鋼都是軋制截面，翼緣內(nèi)邊有1：10坡度。

Ｈ型鋼的軋制不同于普通工字鋼僅用一套水平軋輥，由于其翼緣較寬且無斜度(或斜度很小)，故須增設(shè)一組立式軋輥同時進行輥軋。

The flange of the H steel is equal thickness, has a rolling cross section, and a  section of 3 plates. The I-steel is the rolling section, and the inner edge of the flange has the 1:10 gradient.

The rolling of H steel is different from ordinary I-beam only with a set of horizontal rolls. Because of its wide flange and no slope (or very small slope), a group of vertical rollers should be set up and rolled at the same time. 

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(xué)物理性能。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(jié)構(gòu)與制造安裝。型材的材質(zhì)、規(guī)格尺寸等可參照相應(yīng)的國家標準。軋機結(jié)構(gòu)和軋機布置形式較多。I-steelisdividedintothreekinds:ordinaryI-steelandlightI-steel,Htypesteel。在結(jié)構(gòu)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。

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

細木工板的加工工藝分機拼和手拼兩種，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目，如做實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?；囊话闶悄z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.
