Structural Steels: S235, S275, S355 (2) – Chemical Composition
The Chemical composition of Structural Steels is extremely important and highly regulated. It is a fundamental factor which defines the Mechanical properties of the structural steels material. In the following table you can see the Max % levels of certain regulated elements present in European Structural steels grades S235, S275 and S355. read more →

Definition of Mild Steel
Mild steel is the least expensive of all steel and the most common steel used. Used in nearly every type of product created from steel, it is weldable, very hard and, although it easily rusts, very durable. read more →
What Is Pipe Piling?
Pipe piling is a structural building material used to support and stabilize a building's foundation. When the soil below a building is loosely packed, it may not offer enough strength to keep the building stable over time. A pipe piling can be used to distribute the weight of the building deeper into the earth, where the soil is often more tightly packed. read more →
Steel Pipe Thickness Tolerance of API 5L, ASTM A53 and EN10219
We compare different thickness tolerance of three standard API 5L, ASTM A53, EN10219 specification. You must have the usage and standards requirements before purchase those welded and seamless steel carbon pipes. read more →
Is the API 5L Certificate True ?
API 5L certificate is issued by API (AmericaN Petroleum Institure) for those mills or companies which have been certified by the insiture. Because API 5L specification is applied for line pipe of natural gas or oil industrial. So, there are many strict requirements for API 5L steel pipe. read more →
