角鋼的幾何偏差允許范圍也是有規定的，包括彎曲度、邊寬、邊沿厚度、頂角、理論重量等，并且規定角鋼不應有明顯的扭轉。

生產(chǎn)和實(shí)際使用中主要以形狀分類(lèi)。角鋼的規格用邊長(cháng)和邊厚的尺寸表示。目前國產(chǎn)角鋼規格為2-20號，以邊長(cháng)的厘米數為號數，

同一號角鋼常有2-7種不同的邊厚。進(jìn)口角鋼標明兩邊的實(shí)際尺寸及邊厚并注明相關(guān)標準。一般邊長(cháng)5cm以下的為小型角鋼，

12.5cm—5cm之間的為中型角鋼，邊長(cháng)12.5cm以上的為大型角鋼。角鋼可按結構的不同需要組成各種不同的受力構件，

也可作構件之間的連接件，如房梁、橋梁、船舶、工業(yè)爐、容器架以及倉庫貨架等；用于制做框架結構，例如高壓輸電的塔架、

鋼結構橋梁主梁兩側的框架、建筑工地上塔式起重機的立柱和臂桿、車(chē)間的立柱和梁等，小的地方如過(guò)節路邊擺花盆造型的架子、

在窗戶(hù)下掛空調太陽(yáng)能的架子等；。

The allowable range of geometric deviation of angle steel is also specified, including curvature, edge width, edge thickness, top angle,

theoretical weight, etc., and stipulates that angle steel shall not have obvious torsion.In production and actual use,

it is mainly classified by shape.The specifications of the angle steel are indicated by the dimensions of the edge length and edge thickness.

At present, domestic corner steel specifications for 2-20, with the number of centimeters for the number,

the same horn steel often has 2-7 different side thickness.

The inlet angle steel indicates the actual size and side thickness of both sides and indicates the relevant standards.

General side length below 5cm is small corner steel, between 12.5cm and 5cm is medium corner steel,

and the side length above 12.5cm is large corner steel.Angle steel can be composed of different stressed components, such as beams,

bridges, ships, industrial furnace, container shelves and warehouse shelves, etc.; for making frame structure,

such as high voltage transmission tower, both sides of the main bridge, columns and arms of tower crane, workshop columns and beams,

small places such as holiday roadside pot shelves, air conditioning and solar shelves under the window, etc..
