Q255 Q275 mild steel beam
Q255 Q275 Carbon Mild Steel Beam
Q275 and Q255 are both carbon structural steel, of which, Q275 corresponds to the old brand name A5, belonging to the hot rolled steel plate.
Q275 structural steel has high strength, good plasticity and cutting performance, certain welding performance, small parts can be quenched and strengthened, mostly used in the manufacture of parts requiring high strength, such as gears, shafts, sprockets, keys, bolts, nuts, agricultural machinery with profiles, conveyor chains and links.
Q275 h beam structure is mainly used to make more important mechanical components in construction and bridge engineering.
Q255 steel h beam has good strength, plasticity and toughness, good welding performance and cold and hot pressure processing performance.
Q255 h metal beam is used to manufacture parts with not too high strength requirements, such as bolts, keys, rockers, shafts, tie rods and various steel profiles and plates for steel structures.
