The benefit of using any structural steel is that they have a stiff cross section. The grade of the steel indicates its yield strength. The letter S means this particular steel grade is intended for structural purposes. The number 770 denotes the yield strength value of the material in newtons per square millimeter. The term QL means the S770 QL Structural Steel Tube has been treated by both quenching and tempering. The multiple uses of this steel alloy stem from its properties. The material has high tensile strength with high toughness and toughness, which is specifically useful in the building and construction industry as well as commercial projects. Innately, this steel alloy is known to be noncombustible. However, if the s770 ql Elliptical Hollow Sections Tubing material were to be heated to a very high temperature, similar to that of fire, its properties (strength and toughness) undergo a significant reduction. Because this alloy is a type of carbon steel, it can get corroded by oxidation very easily. In this case, oxides or rust is formed on the surface of s770ql steel Rectangular Hollow Section Tubes, which can lead to an eventual decay of the constructed project. Therefore, it is necessary to perform a surface treatment to prevent the degeneration of this alloy. Usually, paint or an anti-corrosive coat or oil is applied over the s770 ql Carbon Steel Tube to protect it from getting rusted. There is another benefit of using this alloy instead of wood for construction projects. Mold and termites neither affect wood easily nor do they thrive or permit the growth of small insects, ants, or fungus on S770 extra high strength hollow sections Tubes. Industries related to building and construction also prefer using this alloy grade because the strength-to-weight ratio of the S770 ql Seamless Hollow Section Tube is high.
