Type and specification of Angle steel
It is mainly divided into equilateral Angle steel and unequal Angle
steel two categories, which unequal Angle steel can be divided into
unequal thickness and unequal thickness two.
Angle steel specifications are indicated by the dimensions of side
length and side thickness. At present, the specifications of
domestic Angle steel are 2-20, with the centimeters of side length
as the number, and the same Angle steel often has 2-7 different
edge thickness. The actual size and edge thickness of import Angle
steel shall be marked on both sides and the relevant standards
shall be indicated. Generally, large Angle steel with side length
above 12.5cm, medium Angle steel with side length between 12.5cm
and 5cm, and small Angle steel with side length below 5cm.
Import and export Angle steel orders are generally based on the
specifications required in use, and its steel number is the
corresponding carbon bonded steel number. Angle steel in addition
to the specification number, there is no specific composition and
performance series.
The delivery length of Angle steel is divided into two kinds: fixed
length and double length. The selection range of fixed length of
domestic Angle steel is 3-9m, 4-12m, 4-19m and 6-19m according to
the different specifications. The length of Angle steel made in
Japan ranges from 6 to 15m.
The section height of unequal Angle steel is calculated by the
length width of unequal Angle steel. Refers to steel with angular
section and unequal length on both sides. It is a kind of Angle
steel. The side length is 25mm×16mm·200mm× L25mm. It is rolled by
hot rolling mill. General specifications of unequal Angle steel:
∟50*32--∟200*125 thickness of 4-18mm
