Overview of Rebar
Rebar vulgo dicitur, quod calidum convolvit bar- costatum. Gradus ordinarii vectis calido involutus constat ex minimo puncto HRB et gradus cedere. H, R et B primae litterae calidae convolutae sunt, Ribbed and Bars respectively. Rebar secundum vires in tria genera dividi potest : HRB300E, HRB400E, HRB500E, HRB600E, etc.
Filum specificativum range rebar est fere 6-50mm. Solent plus involvere 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm et sic porro. Nationalis licita declinatio: 6-12mm declinatio in ±7%, 14-20mm declinatio in ±5%, 22-50mm declinatio in ±4%. Fere certa longitudo rebar est 9m et 12m, inter quas 9m longa stamina maxime adhibita ad constructionem viarum normalem et 12m longam stamina maxime ad constructionem pontis adhibentur.

| Processus productionis | Rebar est vectis ferreus superficiei costatae, praeterea subsidii costatis nota, plerumque cum costis 2 longitudinalibus et costa transversa aequaliter secundum directionem longitudinis distributa. Figura costae transversalis est figura spiralis, figura herringonis et figura lunatis. In terminis millimetris diametri nominalis. Nominalis diametri firmatae subsidii aequalis est diametro nominali levis rotundi subsidii cum sectione transversali. Diameter nominalis vectis ferrei est 8-50 mm, et commendata diametri est 8, 12, 16, 20, 25, 32 et 40 mm. Serae maxime distrahentes accentus in concreto sustinent. Talea ferrea costata actionem vim externae melioris ferre potest propter effectum costatis et concreti. Vectes costatae late in variis aedificiis structurae utuntur, praesertim magnae, graves, leves, tenuia et alta aedificia. |

| Applicationem | Rebar late usus est in aedificatione, ponte, via et aliis machinationibus civilibus constructionis. Ex via, ferriviaria, pontis, culverti, cuniculi, inundationis, fundi et aliarum facultatum publicarum, ad fundamenta aedificiorum, trabes, columnae, moenia, laminae, cochleae ferrum, materiae structurae necessariae sunt. Penitione urbanizationis Sinarum, postulatio rebar valida est ad constructionem infrastructuram et ad realem praedium sonantem progressionem. |
