The iron and steel industry has been maintaining its place and importance in the world for a long time. No matter how far humanity goes better, it cannot take the necessary steps without the companionship of iron and steel. This ensures that the iron and steel industry always has a significant place in the business world. Innovations such as rectangular solid iron (rectangular rails) developed to strengthen this place increase the prestige of this sector.

Innovation has become a term we come across constantly in the literature. The world is also shaped around this term.People are constantly chasing innovation and the conveniences that this innovation will bring. Million-dollar companies devote incredible budgets to their R&D departments. This naturally enables innovation and humanity to go one step further. Even on a sectoral basis, the benefits of technology are too many to count anymore. Every day, a new one is added to the innovations that are beneficial to each sector in their own way. The iron and steel industry, which is one of the sectors necessary for the continuity of humanity, also gets its share from these innovations.

Sometimes innovations made in production methods can sometimes show themselves in product diversity. This innovation, which manifests itself as square filled iron, gives birth to rectangular solid iron with a slight variation in dimensions. It is an undeniable fact that these two products, which are the same logically, provide many sectors from the construction sector to the railway sector. Thanks to the flexibility they provide in production processes, the time saved returns profit to every producer. In a way, he reflects the saying that time is money.

RECTANGULAR NPI IRON TYPES

Of course, certain stages must be followed in the production of these products, which have a very wide usage area. These steps, called cold drawing, enable the product to be easily processed. As you know, cold drawing means reworking the iron after hot drawing. The steps can be listed as follows:

1. 1 Surface cleaning : After the hot drawing process is completed, the surface of the iron is cleaned by sandblasting.
2. Drawing : After the surface is cleaned, the product is laid on the material beds and pulled in the desired caliber.
3. Straightening: In order to provide strength, the product is passed between rolls and presses.
4. Cutting : It is the cutting of the product to the desired length after straightening.
5. Shaping : It is the process of angularly cornering the product in square, rectangular, round or hexagonal shapes according to the customer's request.
6. Normalizing : It is the heating of the material after it has been shaped to make it durable.

The product, which is shaped by going through all these stages, is ready for the use of manufacturers. Thus, products in the size and shape desired by the customer are prepared. 

Dimensions of rectangular NPI irons are as follows:

 The usage area of rectangular solid iron is extremely wide. It can be used for rail iron in the railway sector, as column iron in the construction sector and as an auxiliary element in many sectors. It can be reshaped and adapted at any time. The reason for all of this, of course, is the material from which it is produced.

Rectangular solid irons produced in EN 10278 standards are suitable for cold drawing. This allows them to easily take the desired shape. However, this flexibility does not make them perishable and perishable products. On the contrary, these products are extremely wear-resistant, long-lasting and high- strength.
