why is steel used in scaffolding?

Question

what physical properties on a molecular level does steel have that make it suitable for scaffolding.

Answer 1

#The most common properties include strength, yield strength, elastic limit, proportional limit, ultimate tensile strength, ductility, toughness, fatigue ratio, and loss coefficient. These all are present in the steel.

#The basic materials for scafolding are tubes, couplers and boards.

Tubes are either steel or aluminium. If steel they are either 'black' or galvanised. The tubes come in a variety of lengths and a standard diameter of 48.3 mm. (1.5 NPS pipe). The chief difference between the two types of tubes is the lower weight of aluminium tubes (1.7 kg/m as opposed to 4.4 kg/m) and also a greater flexibility and so less resistance to force. Tubes are generally bought in 6.3 m lengths and can then be cut down to certain typical sizes.


Extensive scaffolding on a building in downtown Cincinnati, Ohio.Boards provide a working surface for users of the scaffold. They are seasoned wood and come in three thicknesses (38 mm (usual), 50 mm and 63 mm) are a standard width (225 mm) and are a maximum of 3.9 m long. The board ends are protected by metal plates called hoop irons or sometimes nail plates. As well as wood steel or aluminium decking is used or laminate boards. As well as boards for the working platform there are sole boards which are placed beneath the scaffolding if the surface is soft or otherwise suspect, although ordinary boards can be used, and meet the minimum requirements, they can be too long and tougher boards can be necessary.


A short section of steel scaffold pole.Couplers are the fittings which hold the tubes together The most common are called scaffold couplers, there are three basic types: right-angle couplers, putlog couplers and swivel couplers. To join tubes end-to-end joint pins (also called spigots) or sleeve couplers are used, or both together.

Answer 2

tubes and pipes are used in scaffolding and both steel and aluminum are used since new aluminum alloy used to manufacture a strong light eight scaffold and this kind was first used in maintaining the statue of liberty in manhatten
for steel scaffolds A36 steel is used

Answer 3

On a molecular level steel is ductile. The carbon steel used is a low in carbon & alloys which makes it cheap.

Answer 4

The reason is simple.....Bamboo will bend in the event of a typhoon and is thus safer than steel scaffolding.

Answer 5

It is strong for its weight and can be made tubular for fitting together. Bamboo is used for scafolding on multistory buildings in Thailand - or was.
