SAE1080 is a high-carbon steel that belongs to the American Standard (SAE).

Cold-formed steel is a kind of hot-rolled or cold-rolled strip steel as a billet, at room temperature by pressure processing made of a variety of complex cross-section profiles.

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.

I-beam, also known as steel beam (English name Universal Beam), is a long strip of steel with an I-shaped section. 

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. 

I-beam is a common structural steel with light weight, high strength and easy construction. 

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. 

Galvanized flat steel in fact refers to a 12-300 mm wide, 3-60 mm thick section of rectangular and slightly with tons of edges of a steel, which can be used as a finished steel, but also as a galvanized pipe billet and galvanized strips, as a finished product can be used in the production of hoops, tools and machinery parts, if used in construction can be used as a structural member of the frame and escalators.

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.
