The transverse rib geometry of imported rebar is mainly ordinary square thread or ordinary oblique square thread. The transverse rib geometry of domestic rebar mainly includes spiral shape, herringbone shape and crescent shape. The order principle of rebar is generally based on the mechanical process performance or mechanical strength index on the basis of meeting the gripping performance requirements required by engineering design.
British standard rebar is a steel material commonly used in construction projects. It has the characteristics of high strength, good plasticity and good welding performance, so it is widely used in the field of construction.

B460B
British Standard 460B rebar is a rebar product that meets the British standard (BS4449-2005 standard). Its material is B460B, which is a ribbed steel bar on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length direction, and the shape of the transverse ribs is spiral, herringbone and crescent shape.
Performance characteristics of British standard 460B rebar
Adhesion with concrete: due to the role of the rib, and concrete has a larger bonding capacity, so it can better withstand the effect of external forces, so it is suitable for all kinds of building structures, especially large, heavy, light thin-wall and high-rise building structures.
B500B
British standard rebar standard b500b has a tensile strength range of 620-780 N/mm² Yield strength range of 410-550 N/mm² and elongation range of 17%-21%. Its carbon equivalent should not exceed 0.50%, and the content of phosphorus and sulfur should be as low as possible to ensure its excellent mechanical properties and weldability.
British standard rebar standard b500b is mainly used to manufacture threaded connectors with high strength, high corrosion resistance and high toughness, such as bolts, nuts, screws, rivets, pins and so on. Due to its excellent mechanical properties and welding properties, as well as high strength and toughness, it is widely used in construction, Bridges, railways, vehicles, ships, machinery and other fields.
B500C
1. British Standard B500C rebar is a low-alloy high-strength steel with a strength grade of B500C.
Its tensile strength has reached 500MPa, which belongs to the category of high-strength steel.
2. Application field
First of all, it is often used in the reinforcement and reinforcement of reinforced concrete beams, columns and plates in concrete structures.
Its high strength and good plasticity can increase the bearing capacity and seismic performance of concrete structures.
Second, British standard B500C rebar can also be used to make prestressed components, such as prestressed concrete beams and prestressed concrete slabs.
In addition, British standard B500C rebar is also commonly used in the production of reinforced concrete piles, anchor rods and retaining walls and other engineering structures.
