A few common types of structural steel pipes used in construction projects

For a long time, structural steel pipes have been widely used as an important building material in the construction industry, which serve a wide range of functions often, due to the good performances of durability, strength and resistance to harsh environment conditions. In the current steel pipe market, structural steel pipes are available in a variety of sizes and grades so that it can be used for a number of different structural uses and applications in the construction trade. How much do you know about the common types of structural steel pipe in the steel pipe market?

Square steel tubes are one typical member of structural steel pipes that are commonly used for construction framing, truck racks and beds, trailers, ornamental objects and railings in the modern times. Many dune buggies are built by using square tubing for the framing and round tubing for the roll bars. In most cases, square tubing is easier to cut and weld. Square steel pipe is usually used for steel structure in construction engineering, for framing tubes provide stability, uniformity, strength and soundness to structures that endure a great amount of stress. For example, hot dipped galvanized steel pipe is very popular in the construction field currently. It is strongly proposed that customers in the actual purchase process, should carefully refer to the quotations from manufacturers, and then try to select the right products for the practical purposes from some aspects such as the amount of zinc layer, pipe diameter, pipe length, wall thickness and raw materials.

Rectangular steel pipe is another one popular structural steel pipe in the current steel pipe market. Torsional strength makes rectangular steel pipe an excellent choice for bearing 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. In addition, rectangular steel pipe can be readily bent, formed, punched, and drilled. New and improved methods to fasten rectangular steel pipe or to other materials are making its use simpler and fabrication faster. In general, rectangular hollow sections are cold formed and welded from either hot rolled steel, cold rolled steel, pre-galvanized steel or stainless steel. ASTM A500 is the most common steel specification for rectangular structural section in the current steel pipe market around the world.
