SAE1006 flat steel is a low-carbon steel material with high elongation and smooth surface.

Angle steel Q235 is a kind of carbon structural steel, that belongs to ordinary carbon structural steel.

Q235B channel steel is a long strip of steel with a groove-shaped cross-section.

Angle steel belongs to construction carbon structural steel, is a simple section of steel, in the use of good weldability, plastic deformation and mechanical strength. 

Flat bar A36 is a common building material, often used in support structures, bridges, construction and machinery manufacturing.A36 is an American Standard carbon structural plate, which conforms to ASTM A36/A36M-03a.

Flat bar steel is steel with a long cross-section, and commonly used materials include ordinary carbon steel, alloy steel and stainless steel. The shape of its cross-section is characterized by flatness. Flat steel is characterized by uniform material, easy delivery, and moderate price, and widely used in various fields. 

Equal angles are angles with equal sides. Angle bar steel specifications are expressed in millimetres of side width × side width × side thickness. EQUAL ANGLE Steel angle bar can be composed of various stress-bearing components according to different needs of the structure, and can also be used as a connector between components. 

H-beam is a kind of economic cross-section high-efficiency profile with a more optimised cross-sectional area distribution and more reasonable strength-to-weight ratio, which is named because its cross-section is the same as that of the letter "H" in English.
