ASTM a36 a53 Q235 Q345 carbon equal angle steel galvanized L shape mild steel angle


Carbon Structural Steel Introduction

Carbon steel structural shapes are ideal for construction where high strength is required but the low luster is not an issue. Our stock of Carbon structural steel includes a wide variety of shapes and sizes.


Angle steel belongs to carbon structural steel for construction, which is a kind of simple section steel, mainly used for metal components and workshop frames. Weldability, plastic deformability and certain mechanical strength are the requirements for use. The raw material of the angle steel produced is low carbon billet, and the final angle steel is delivered in hot-rolled, normalized or hot-rolled state.

Benefits: Destroy the ingot structure, refine the grains of the steel, eliminate the microstructure defects of the steel, make the steel structure dense, and improve the mechanical properties of the steel. This improvement is mainly reflected in the rolling direction, so that the steel no longer has a certain isotropy; the bubbles, cracks and porosity formed during the casting process can also be welded by high temperature and high pressure.

Carbon Structural Steel Angles

Carbon steel angle is hot rolled steel or high strength low alloy steel bars shaped to a 90 degree ‘L’ shaped bar. The sides or legs of the “L” may be equal or unequal. Other names for carbon steel angle are angle irons or steel angle bars. Structural steel angle shapes are often used in applications that aid in improving rigidity and good resistance to bending in any direction. Because of its high cost performance, angle steel is widely used in housing construction, bridges, tunnels, wire towers, ships, brackets, steel structures and other fields to support or fix structures.


We stock steel angles in the following grades: Q235B steel angle, A-36 steel angle, A-36 galvanized steel angle.

Carbon Structural Steel Beam

Structural Steel Beams come in I-Beam and H-Beam. All are designed to span an area for support in construction. The shape of a beam affects the overall strength and weight. W or Wide Flange Beams have a broad flange on either side of the web. They are the most common due to their proven ability to withstand shear loads and bending. We stock carbon steel grade 1045 beam, ASTM A992 (A572 Grade 50), and A529-50 Structural Beam. 


I-Beams, also known as H-Beams have an I or H cross-section. The horizontal elements of the “I” are flanges while the vertical element is the “web”. I-Beams are commonly made of structural steel but can be formed out of aluminum. I-beams are most widely used in construction and can have an application for use in both beams as well as columns. We stock many different sizes, lengths, and specifications for I-beams.

Essential for Structural Applications

A36 steel is a very frequently used mild- or hot-rolled steel. It maintains a somewhat rough surface and can be machined and manipulated using a variety of processes. These include multiple types of welding, as well as grinding, drilling, punching, and riveting.

Its flexibility and strength make A36 steel suitable for a full variety of applications, including fixtures, rings, forming tanks, bearing plates, cams, and gears, among many others.

Strength and Flexibility

With a tensile yield strength of 36,300 psi and an ultimate tensile strength that ranges from 58,000 to 80,000 psi, A36 steel combines strength with flexibility. A36 steel can maintain its strength at temperatures ranging up to 650°F. This metal is excellent for welding and produces high quality welded joints. While A36 is a strong material, it is more easily bent than materials such as C1018 steel, as it has less yield strength.
