Typical Applications

Structural Steel tube (tubing) can be used for a wide variety of mechanical applications. It may be used either statically or dynamically. Its’ close tolerances, good finish, and dense structure make it ideal for parts such as structural support and parts, frames, racks, trailer beds and trailer components, structural components and supports for buildings, bridges, and highways, conveyors, machine parts, guides, and supports, safety and deck rails, sign posts, athletic equipment, ornamental usages and a wide range of applications in industrial, construction, automotive, appliance, furniture and agricultural industries.


There several effective tests are conducted in order to bring out the very good quality of the product. The testing is positive material identification test, intergranular corrosion test, pitting resistance test, hardness test, chemical analysis, mechanical test, radiography test, hydrostatic test. More test like eddy current test, flattening test, flaring test, ultrasonic test, macro test, micro test is performed.


SS400 steel can have ultimate tensile strengths from 58,000 to 79,800 psi. The exact ultimate tensile strength is determined by a variety of factors such as chemical composition and forming method. A36 is relatively ductile and can elongate to around 20% of its original length when tensile testing. Its ductility and strength also give it excellent impact strength at room temperature.
