Hot Rolled Plain Bars Use
Hot rolled plain bars is finished steel after hot rolling forming and natural cooling.By low carbon steel and ordinary alloy steel under high temperature condition suppression and become, is mainly used for reinforcement of reinforced concrete and prestressed concrete structure, is the usage of civil building engineering one of the largest steel varieties.Dia 6.5-9mm,most of the rolled wire rod.Dia 10-40mm is the lengh of 6-12m.Hot rolled steel bar should have a certain strength, the yield point and tensile strength, it is the main basis of structure design. Divided into hot rolled round steel bar and hot rolled ribbed steel bar two kinds.chinacoal05
