Qalabka dhexdhoobka ah ee gaar ah waxaa lagu yimid in uu ka soo jeeda hadashadda koonfurta ee xaaladaha ku jiraan, mid ka badan oo ku yaal qeybaha carruurta ee carruurta adeegga ah ee lafaha iyo carruurta adeegga ah ee lafaha. Qeybka ah ee dhexdhoobka ugu yaraan 8mm to 16mm, markii ay ku sameyn doonaa qaysooyinka ah ee ASTM A615 Grade 40 (USA), B500A (Europ), ama HRB 400 (Xinaxi), ku saabsan yihiin qaysooyinka ah ee 276 MPa to 400 MPa—waxyaabka ah ee ku jiro carruurta adeegga ah ee lafaha, dhalalka, iyo carruurta adeegga ah ee labaada. Dhexdhoobka ah ee qalabka ah ugu yaraan deegaanka ah (ribs) ee ku yimid standaarka carruurta ah ee ku jirin bondiga ah ee qalabka ah ee ku jiran, marka aan ugu yimaado rib height ee 0.5mm iyo degdeg ee 15mm ee ku jiran si aad u baahan tahay qalabka ah ee ku jiran carruurta adeegga ah ee lafaha. Waxbarashada qalabka ah ee dhexdhoobka ah ugu yaraan ductility (elongation at break ≥18%) ee ku jiro si aad u baahan tahay carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha, sidaas daraaddeed weldability ee ku jiro si aad u baahan tahay carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha. Dhexdhoobka ah ee carruurta adeegga ah waxaa loo baahan yahay carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha, laakiin galvanized ama epoxy coated options waxaa loo baahan yahay carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha ee ku jiran carruurta adeegga ah ee lafaha. Waxbarashada carruurta adeegga ah ee ku jiran carruurta adeegga ah ugu yaraan dhexdhoobka ah ee ku jiran carruurta adeegga ah ee lafaha (typically 150–200mm centers) ee ku jiran carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha. Suppliers waxaa loo baahan yahay dhexdhoobka ah ee pre cut iyo bent carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha, si aad u baahan tahay carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha. Compliance with building codes waxaa loo baahan yahay carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha, marka aan ugu yimaado International Building Code (IBC) ee USA, ee ku jiran carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha. Carruurta adeegga ah ee dhexdhoobka ah waxaa loo baahan yahay carruurta adeegga ah ee ku jiran carruurta adeegga ah ee lafaha, markii aan ugu yimaado materials maintaining at least 80% of their yield strength at 300°C for the duration of typical fire scenarios.
