Section steel 
is a kind of strip steel with certain section shape and size. 
According to the section shape, the section steel is divided into simple section steel and complex section steel .
The former refers to Square steel, Round steel, Flat steel, Angle steel, Hexagonal steel, etc;
The latter refers to I-beam, Channel steel, Rail steel, Window frame steel, Bending section steel, etc.

SECTION STEEL
Angle steel	Angle steel is a structural steel for construction, which is a section steel with simple section, It is mainly used for metal components and plant frame. In use, it is required to have good weldability, plastic deformation performance and certain mechanical strength.
Channel steel	Channel steel is a long strip of steel with groove section, which belongs to carbon structural steel for construction and machinery. Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.
H-beam	H-beam steel is a kind of economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. Because all parts of H-section steel are arranged at right angles, H-section steel has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions
I-beam	I-beam is also called steel beam, It is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. More members are directly used for bending in the plane of their webs or form lattice stressed members.
Flat steel	Flat steel refers to steel with width of 12-300mm, thickness of 3-60mm, rectangular section and slightly blunt edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate. Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings.
