dibadda 12mm Steel Rebar | Rebar Been Ah Si Loogu Dheerayo Construction

kuushaada rebar steel 12mm waxaa ka mid ah kuushaada rebar qofka ee uu ugu yarreeyey in lagu ammaansan yahay oo ku jiraan dhexeefaha, caalista iyo xirfadda guriga ee ay ku jirtaan dadweynaha, caalmada iyo xirfadda shaqsiyada la xiriira, sababtaas waa lacag dheer, adeegsiga ah, iyo adeegga carruurta ah. Kuushaadahaas oo lacagtoobinna 12mm (≈0.47 duq) waxaa loo isticmaal doonaa marka uu u soo baxaan macluumaadka carbon steel kamaa ASTM A615 Grade 40 (lacagtoobin cabsiyeedka 276 MPa) ama HRB 400 (lacagtoobin cabsiyeedka 400 MPa), kuwaas oo adeegsiga lacag dheer ah ee u baahan yahay lacagtoobinta carruurta ee carruurta ah. Proseska badbaadinta ayaa ugu yarreey inuu ku jirtaan cold rolling ama hot rolling, markii uu rib patterns u baahan yahay si uu ku haysto adeegsiga adeegsiga ah ee ku jiraan concrete adhesion—ribs standard ee ku jiraan ISO 15630 1 ayaa u baahan yihiin adeegsiga bond strength ee ku jiraan 1.5 kaliya lacagtoobinta carruurta ee carruurta ah. Kuushaada oo ka mid ah ayaa ku sameeyeen sheekooyinka aasaasiya ah, ku raacayso testing ultrasound ee ku jiraan defects carruurta, surface hardness tests, iyo certification ee ku jiraan elongation at break (≥16% marka uu ku jirto ductile grades) si uu u baahan yihiin standard carruurta ah ee dhammaantaa. Kuushaadaha 12mm ayaa ugu yarreeyey inuu ugu ammaansan yihiin marka ugu leedahay residential floor slabs, wall reinforcements, staircases, iyo commercial building partitions, sababtaas waa adeegsiga ah ee ugu yarreeyey inuu ku jirtaan handling, bending, iyo tying with wire ties. Kuushaada oo ka mid ah ayaa ku sameeyeen service carruurta ah ee ku jiraan pre cutting to project lengths, bending into L shaped ama U shaped configurations marka uu ugu yarreeyey corner reinforcements, iyo galvanization ama epoxy coating si uu ugu yarreeyey inuu ku jirtaan resistance carruurta ah ee ku jiraan humid environments. Management carruurta ah waa labaashada, sababtaas kuushaada 12mm ayaa ku jiraan products volume ah ee uu ugu yarreeyey inuu ugu ammaansan yihiin marka uu ugu leedahay ongoing construction projects. Suppliers carruurta ah internationale ayaa ku sameeyeen inuu ugu yarreeyey regional standards carruurta ah ee dhammaantaa—for example, complying with EN 10080 (European rebars) ee ku jiraan chemical composition limits for weldability, ama AS/NZS 4671 (Australian/New Zealand standards) ee ku jiraan stricter tolerance for rib spacing. Technical support carruurta ayaa ku sameeyeen inuu ugu yarreeyey architects designing reinforced concrete elements, calculating rebar coverage ratios, iyo advising on best practices for concrete curing si uu ugu yarreeyey composite structural performance.
