1,The character of steel fiber for concrete:
The steel fiber mainly uses in concrete material.The steel fiber concrete is a new type of compound material through rapidly developing since recent twenty years,because the material is added with uniform distributing short steel fiber compound material.It has good crazing-resistance,anti-freezing,
anti-bend,antiwear,washing-resistance etc.It has not only the good character of the normal concrete,but also it makes fragile concrete show good ductility and toughness,as well as nice anti-freezing,antiwear etc.

8,We can provide the steel fiber for pouring and jet.
9,Choice scope to the volume rate of the steel fiber
(1) The general shaped structure pouring 0.5%----2.0%
(2) Partial pressure structural component,bridge surface,precasted pile,pile head,pile nail 1.0%--1.5%
(3) Railway sleeper,water-proof roofing 0.8%---1.2%
(4) Jet steel fiber 0.5%----1.5%
10,The use of steel fiber:
It is mainly used in highway,airport,the roof of the house,bridge,tunnel,
mine and so on.
11,How to use steel fiber:
1) For the sake of keeping uniform,first mix with other materials 1.5 or 2 minutes without water,1 or 2 minutes more than ordinary concret’s agitating.
2) To press steel fiber down mortar after finishing surface work,there aren’t discovering steel fiber on mortar surface.
12,Packing:
in 25kg kraft bag lining plastic woven bag .
