Why does rectangular steel pipe become so popular today

In the current steel pipe market, hollow section tubes make a hit in a variety of applications. Especially, when it comes to construction projects, hollow section tubes are used in many building types from small storage units to skyscrapers in big cities. For example, they are used to create the foundation of large buildings as well as other framework.

Torsional strength makes rectangular steel pipe an excellent choice for bear resistant and consistent. Rectangular steel pipe is fire resistant and does not warp, twist, split, swell or shrink. 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. Rectangular steel pipe can be readily bent, formed, punched, and drilled. And improved methods to fasten Rectangular steel pipe to other materials are making its use simpler and fabrication faster.

In applications, rectangular steel pipe has many benefits: aesthetic appeal, high strength-to-weight ratios, uniform strength, cost effectiveness and recyclability. Hot dipped galvanized steel pipe has been considered popular a lot among many users today. For one thing, the galvanization process protects the steel from rusting damage that can occur during transportation, installation and service. The zinc layer on the surface of pipe can form a barrier protection for steel products to extend the service life in applications. For the other thing, this layer is also resistant to wear and scratch, which makes the steel look more attractive. With the layer of protection, pipes can be used in outdoor areas, and can withstand the harm from some of the environmental effects.

Cold rolled steel pipe has an improved surface finish and tighter tolerances when compared to hot rolled steel pipe in the market. It is commonly used for parts requiring cold forming, such as crimping, swaging or bending. It can also be used for shafts, machinery parts, bolts, pinions, gears, as well as in the creation of furniture, appliances and other consumer goods. Furthermore, this type of rectangular steel pipe is sometimes preferred for architectural aesthetics in exposed structures in construction field due to its flat square surfaces. ASTM A500 is the most common steel specification for hollow structural section in the current steel pipe market around the world. This specification is for cold formed welded and seamless carbon steel tubing in round, square and rectangular shapes. ASTM A501 is another standard for hot formed steel tubing.
