Square steel pipes have different sizes, specifications and wall thickness.Its unity makes its use and visual appeal predictable.It is of high weight.to-strength ratio.It is easy to bend because the square steel pipe is cheap, so its cost-effective --Even large projects.Steel pipes are easy to recycle.Many projects take advantage of square steel pipes, including all types of buildings, road guardrails and signage, support columns, truss, bridges, heavy equipment, storage systems and sports equipment.The North American steel pipe Research Institute specifies the external width measurement of square steel pipes.For example, with 2-An inch wide side makes a sound of 2 by 2 inch.Size range from 1-1/4 by 1-1/4 to 32 by 32 inch.From 1-1/4 to 2-1/2, size varies from quarter to quarterinch.For 2-1/2 to 5-1/2, half the size.inch.In addition to this, the size of the pipe is only every inch.The wall thickness of square steel pipes ranges from 1/8 to 5/8, also known as No. 11 gaugeinch thick.The thicker walls are only larger.For example, when the thickness of the 6-by 6 inch steel pipe is 5/8 and 1/2, 5-1/2 by 5-1/2 does not.The weight-per-Depending on the wall thickness and nominal size, the specifications of the feet vary.The North American steel Institute claims that the use of square steel pipes can reduce weight compared to other steel structures.Weight savings save costs during transportation to work place.Square steel pipes have standardized engineering specifications.These include: Cross-twist shear constantCross section, moment of inertia of Cross SectionTorsional stiffness constant of Cross SectionSection, radius of rotation, modulus of elastic section and modulus of plastic section.Some of these specifications are for X-X and Y-Y axes.For the exact specifications for each nominal size and wall thickness, see resources.
