Black Annealed Wire is made of carbon steel wire(Q195), it's obtained by means of thermal annealing, endowing it with the properties it needs for its main use setting. and it's deployed both in civil construction and in agriculture in general. hence, in civil construction annealed wire, also known as "binding wire". We can provide all diameter of black annealed steel wire ,mainly BWG16 black annealed wire.
Silk number, also known as line number, wire gauge (wire gauge), according to these figures 1,2,3 order to identify, the larger the number, the thinner the wire diameter. 300 years ago, no rolling and extrusion technology, wire rod, forming forging technology is very primitive and simple measurement tools are very rough, so the printing on the number of times drawn as a wire thickness standards. One pull each time increase, compared to the blank line number 0. Because there are many workshops, craft and not the same, so the wire diameter is no uniform standard. Later, the prosperity of the global trade, internationally recognized standards began to take shape, in addition to the common metric units of measurement methods, American Wire Gauge (AWG), Birmingham Wire Gauge (BWG) and the British Empire Standard Gauge (SWG) are also recognized by the international trade measurement methods.
