Product Description

Carbon Structural Steel Angles ASTM A36 Equal 50*50*6mm For Bridges Warehouses


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.


Features of angle steel:


1. The angular structure makes it have good supporting strength.
2. Under the same supporting strength, the angle steel is lighter in weight, consumes less material, and saves costs.
3. The construction is more flexible and takes up less space.

Carbon Structural Steel Angles

It is mainly divided into two types: equal-sided angle steel and unequal-sided angle steel. Among them, the unequal-sided angle steel can be divided into two types: unequal-sided and equal-thickness and unequal-sided and unequal-thickness.
The specification of angle steel is expressed by the dimensions of side length and side thickness. At present, the domestic angle steel specifications are 2-20, and the number of centimeters of the side length is the number. The same angle steel often has 2-7 different side thicknesses. Imported angle steel indicates the actual size and thickness of both sides and the relevant standards. Generally, large angle steels with a side length of 12.5cm or more are medium-sized angle steels with a side length of 12.5cm-5cm, and small-sized angle steels with a side length of less than 5cm.


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.

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.
