SHEET PILES

Steel Sheet Piles

Introduction

As the latest investment brought to life in November 2008, MMZ’s Steel Sheet Pile production line is a very strong and meaningful symbol of the dedication to R&D. The key feature of the production line is its capability to produce an almost infinite range of shapes by modifying angles, thickness, height, width and shape of the product. This, combined with a capable engineering design department, allows the most suitable product to be offered for even the most challenging projects as well as shapes that are commonly requested by the market. In the light of this strength, MMZ becomes a reliable solution partner for most of its customers.

 

Production Facilities

As the first mill to produce steel sheet piling in Turkey, MMZ has invested in the steel sheet piling production significantly. This is stapled by the fact that the production line is the design and self-production of MMZ. More investments had been made since the establishment of the line and more are still being made.

​The based on these investments, cold formed steel sheet piles from 5 mm to 12,5 mm (0.196 inch to 0.492 inch) can be produced with the above mentioned near limitless possibilities.
 

Advantages of Cold Forming:

In cold forming, sections are produced within close tolerances when compared to hot formed sections. Since material undergoes a pseudo-phase transition during hot forming, it is harder to handle the material and to stay within limits; whereas in cold forming, precisely produced steel sheets are bent through mills allowing us to deliver the product precisely as we offered.

in cold forming, high strength-to-weight ratio is achieved which makes cold formed products easier to transport and erect.

On the contrary what is commonly believed among construction professionals, from the engineering point of view, given the same steel grade and properties, cold formed steel sections result in higher yield strengths. This is due to the phenomenon known as strain hardening which is the consequence of cold working. During cold forming (bending) of steel, there occur dislocations within the crystal structure of the material. As those crystals are dislocated, they get more pinned and tangled to each other making it harder to move them further which in turn enhance the strength of the material. This process, in fact, is used as a way of hardening of materials and is known as cold working in literature. As can be seen from the stress-strain diagram given below, as the material undergoes cold working, mean yield stress changes from point A to point B on the diagram. In order to give an idea about the extent of this increase in the performance of the material, 15%-30% increase can be achieved depending on the cold working process.
