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.

1. The use of black annealed wire
   It can be used to bundle items, commonly used wire diameter range is between 1.2 to 2.0. We will wire the second annealing treatment, so that the wire is more flexible, easy to operate.
2.  The color of black annealed wire
   Without any surface treatment, the surface is black. We can spray through the surface, let it become black and bright colors, and have a certain anti-rust performance.
3. The best weight of black annealed wire in single roll
   General 15 to 30kg more appropriate, often do the weight is 20kg. Too heavy to use when inconvenient, too light will increase the production cost.
4. The volume of containers
   According to the national customs, shipping companies on the container weight limit, generally not more than 25 tons.
