Rectangular steel pipe is considered very important structural material in building projects

Rectangular steel pipe has been widely used as structural material in building projects for many years today, for it has such many benefits as: aesthetic appeal, high strength-to-weight ratios, uniform strength, cost effectiveness and recyclability in applications.

In some particular applications, rectangular steel pipe is considered an excellent choice for bear resistant and consistent, because it is fire resistant and does not warp, twist, split, swell or shrink in use. It resists dry rot and mildew, termites and carpenter ants. For increased fire resistance, the exterior of the product may be sprayed with a fire retardant material. The interior can be filled with concrete. In the current steel pipe market, cold rolled steel pipe are very popular among users because it has an improved surface finish and tighter tolerances and also can be readily bent, formed, punched, and drilled. New and improved methods to fasten cold rolled steel pipe or to other materials are making its use simpler and fabrication faster. In addition, cold rolled steel pipe is more precise dimensionally because it has already gone through the cooling process, which helps it closer to the finished dimension while the hot rolled steel forms the finished product looser tolerances than the original material. In that regard, steel pipe price is relatively high in comparison with hot rolled one in the market.

Tianjin rectangular hollow sections are widely used as structural steel pipes in more and more construction projects in the modern times because this type of steel pipe are high tensile property, flexible, e.g, can be designed and fabricated to any height and strength, are easy to install, possess structural reliability, easy to maintain and are corrosion resistant. ASTM A500 is the most common steel specification for hollow structural section in the current steel pipe market around the world today. This specification is for cold formed welded and seamless carbon steel tubing in round, square and rectangular shapes. Unlike other structural steel materials, Tianjin rectangular steel pipe is immediately ready for use when it is delivered. No additional preparation of the surface is required, no time-consuming inspections, additional painting or coatings are needed. Once the structure is assembled, contractors can immediately begin the next stage of construction without having to worry about the galvanized steel materials.
