普通角鋼主要指的直接熱軋出來(lái)沒(méi)有經(jīng)過(guò)任何加工的角鋼。角鋼表面質(zhì)量在標準中有規定，一般要求不得存在使用上有害的缺陷，

如結疤、分層、裂縫等。角鋼幾何形狀偏差的允許范圍在標準中也有規定，一般包括彎曲度、邊寬、邊厚、頂角、理論重量等項，

并規定角鋼不得有顯著(zhù)的扭轉。角鋼屬建造用碳素結構鋼，是簡(jiǎn)單斷面的型鋼鋼材，主要用于金屬構件及廠(chǎng)房的框架等。

在使用中要求有較好的可焊性、塑性變形性能及一定的機械強度。生產(chǎn)角鋼的原料鋼坯為低碳方鋼坯，成品角鋼為熱軋成形、

正火或熱軋狀態(tài)交貨。鍍鋅角鋼分為熱鍍鋅角鋼和冷鍍鋅角鋼。熱鍍鋅角鋼也叫熱浸鍍鋅角鋼或熱浸鋅角鋼。

冷鍍鋅涂料主要通過(guò)電化學(xué)原理保證鋅粉與鋼材的充分接觸，產(chǎn)生電極電位差來(lái)進(jìn)行防腐。

Ordinary corner steel mainly refers to the direct hot rolled corner steel without any processed corner steel.

The surface quality of corner steel is specified in the standard, and generally requires no harmful defects in use, such as scar formation,

stratification, cracks, etc.The allowable range of geometry deviation of angle steel is also stipulated in the standard, generally including bending degree,

edge width, edge thickness, top angle, theoretical weight, etc., and stipulates that angle steel shall not have significant torsion.

Angle steel is a carbon structure steel for construction, is a simple section of type steel steel,

mainly used for metal components and plant framework.Good soldability,

plastic deformation performance and certain mechanical strength are required in use.

The raw material billet for producing angle steel is low-carbon square billet, and the finished angle steel is hot rolled formed,

hot or hot rolled state delivery.Galvanized angle steel is divided into hot galvanized angle steel and cold galvanized angle steel.

Hot dip galvanized angle steel is also called hot dip galvanized angle steel or hot dip zinc angle steel.

Cold galvanized coating mainly ensures the full contact between zinc powder and steel through the electrochemical principle,

and produces the electrode potential difference for corrosion prevention.
