The hooked end steel fibre for concrete reinforcement is a new kind of metal material, in order to enhance concrete and shotcrete in its hardened state. Tengzhou SDS steel fibers make concrete have extremely high flexural strength and shear strength, and have good toughness, crack resistance, earthquake resistance, seepage control and other functions. Widely used in industrial factory floor, highway, high-speed rail, bridge, airport, tunnel, water conservancy, electric power, municipal engineering, etc. The company has passed ISO9001 certification, and its products are exported to Southeast Asia, Europe, America and etc.

The Formation of Steel Fiber
Steel fibers are defined in ASTM A820 as pieces of smooth or deformed fibers that are sufficiently small to be dispersed at random in a concrete mixture. ASTM A820 designates tensile requirements, dimensions and permissible variations. There are mainly 4 steps for steel fibers based on our production process:

Raw Material
Dry Drawing
Glued
stampling & Forming
The Benefits of Steel Fiber

For the same mixing and construction, there is no need to add equipment or increase the construction cost.
Under the same strength requirement, it can replace steel mesh and reduce the pouring thickness of concrete by 15-25%.
Improve the construction conditions, mixing vehicles and construction personnel can reach the site directly, and shorten the construction period by 30%. Steel fiber reinforced concrete has high tensile strength, which can prolong the distance between contraction joints and facilitate continuous and rapid pouring of concrete.
Convenient construction, saving labor, greatly shortening the construction period and saving the total project cost.
The Working Principle of Steel Fiber

Fibers reinforce in three dimensions throughout the entire concrete matrix. Fiber performance is based on the combination of the tensile strength, aspect ratio(length/diameter) and anchorage. The distributed fibers restrain micro-cracking and redistribute accumulated stress caused by applied loads and shrinkage. The sooner the crack is intercepted and its growth is inhibited, the less chance the crack will occur.

FAQs of Steel Fiber
What is steel fiber reinforced concrete?
Fiber reinforced concrete is comprised of hydraulic cements containing fine and course aggregatea and fiber. A super-plasticizer is ofter used to enhance the mix workability. Fiber products are available in a variety of types and sizes. The underlying principle however on all fiber reinforced concrete is to provide discoutinuous reinforcement and effective crack control.

Is there a difference between Micro and Macro Synthetic Fiber?

SDS is one of the steel fiber manufacturer in China and has participated in the construction of national projects several times.
