Reinforcement wire from the low-carbon steel

The feature of steel low-carbon wire for reinforcement of reinforced concrete construction according to GOST 6727-80

1.Wire size and extreme dimensional inaccuracies:

Wire size, mm		Depth of dents, mm		Step of dents, mm		length of projection, mm
Nominal	limit deviuations	Nominal	limit deviuations	Nominal	limit deviuations	Nominal	limit deviuations
3,0	+0,03 -0,09	0,15	+0,05 -0,02	2,0	+0,2 -0,2	0,6	+0,2 -0,2
4,0	+0,04 -0,12	0,20		2,5		0,8
5,0	+0,05 -0,15	0,25		3,0		1,0

2. Steel chemistri:

Nominal wire size,mm	breaking strength,gN (kgf)	Strein,corresponding to conventional yield strength,gN (kgf)	number of bends	percent elongation,%
	Not less than
Reinforcement wire 3,0	39 (400)	35 (355)	4	2,0
Reinforcement wire 4,0	71 (720)	62 (630)	4	2,5
Reinforcement wire 5,0	106 (1085)	97 (985)	4	3,0

3.Wire is produced in skeins. The skein consists of one section of wire. Each skein of wire is tied up by soft wire in four places in the circle of skein. Weight of wire skein is: from 1000 to 1200kg.

4.Wire is transported by all modes of transport in covered transport means with protection from mechanical damages and the entry of moisture, with the observance of rules of freighting, which apply to the relevant mode of transport.
