Grade 40 HRB 400 deformed steel bar
Basic Info
Model No.: ZX-grade 40
Product Description
Grade 40 Grade 60 HRB 400 deformed steel bar
Steel has a thermal expansion coefficient nearly equal to that of modern concrete. If this were not so, it would cause problems through additional longitudinal and perpendicular stresses at temperatures different from the temperature of the setting. Although steel rebar has ribs that bind it mechanically to the concrete, it can still be pulled out of the concrete under high stresses, an occurrence that often accompanies a larger-scale collapse of the structure. To prevent such a failure, steel rebar is either deeply embedded into adjacent structural members (40–60 times the diameter), or bent and hooked at the ends to lock it around the concrete and other rebar. This first approach increases the friction locking the bar into place, while the second makes use of the high compressive strength of concrete.
Deformed steel bar as a important building material, is mainly used in highways, railways, bridges, buildings, municipal construction, reinforced concrete structures.
Normal size of steel rebar are 6mm 8mm 10mm 12mm 14mm 16mm 18mm.
