Section modulus is a term that not many people are familiar with, but this term is something that bending and rolling companies deal with on a daily basis. Section modulus is a geometric property for a given cross-section used in the design of steel beams or flexural members. The relationship between many geometric properties such as tension, compression and shape of the member lead to the calculation of its section modulus.
Profile bending machine can bend most all aluminum structural shapes. Structural shapes can be rolled in to rings for many uses, the corrosion resistance as well as its strength-to-weight ratio make aluminum rings very useful.
Many sports and entertainment arenas use curved aluminum for its light weight and strength when making curved supports for overhead signage, display boards, and monitors.
It’s worth a mention firstly that there are two common terms used in industry, tube bending and pipe bending. Tube is measured by the outside diameter whereas pipe is measured by the inside diameter. Pipe sizing refers to the nominal inside diameter, sometimes called nominal bore, rather than the actual inside diameter.
Bent beams are used everywhere – in structures for functionality or aesthetic appeal, in circular shell stiffening rings on vessels and for monorails or roof trusses. Steel beams can be rolled vertically (the weak-axis) or horizontally (the strong axis). When rolling steel beams, it is important to consider distortion.
Section bending machine can bend all types of pipe and tubing including aluminum, stainless and carbon steel. It even bend specialty materials such as copper, zirconium and titanium.
Rectangular tube bending is the same as rectangular tube bending for the profile bending machine. The difference is that the bending parameter size is determined according to the bending height.
Normal bending tolerances for single radius bends are in line with those specified in the National Structural Steelwork Specification.
