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(wú)斜度(或斜度很小)，故須增設(shè)一組立式軋輥同時(shí)進(jìn)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. 

膠合板是由三層或多層一毫米左右的實(shí)木單板或薄板膠貼熱壓制成，常見(jiàn)的有三夾板、五夾板、九夾板和十二夾板（俗稱(chēng)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).

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.
