EN 10210

  1. PandaPipe manufactures quality EN 10210 Hot Finished Structural Hollow Sections from 1998. 
  2. These hollow sections and tubes, made from non-alloy and fine-grain steels, are designed to meet the rigorous standards of the European Standard EN 10210. 
  3. Our hot-finished hollow sections are formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment to achieve equivalent metallurgical conditions to those obtained in the hot-formed product. 
  4. The superior mechanical properties of our hot-finished hollow sections contribute to the weight reduction of building structures, making them a preferred choice over cold-formed hollow sections.

EN 10210 Specification

Pandapipe offers EN 10210 with a wide range of steel grades such as S235JRH, S275JOH, S275J2H, S355JOH and S355J2H. To provide you with a variety of pipe end connection methods such as flat end, inclined end, groove and thread to meet your project needs. In addition, steel pipes are protected by surface treatments such as galvanized and fused epoxy coating.

EN 10210 Steel Grades

EN 10210 has a number of steel grades and the main difference between the different grades of pipe is the yield strength/impact capacity etc. The following is an introduction to the designation of the different grades of pipe produced by Pandapipe. In the following section, we will introduce the designation criteria for the different steel grades of EN 10210 pipes produced by Pandapipe.

Please note that Pandapipe’s pipes are manufactured in strict compliance with the standards to guarantee the quality and durability of the pipes.

S: indicates that the pipe is a structural steel pipe.
Numbers: The number after S represents the minimum yield strength of the material.
J: the number after the J represents the impact work of steel at different temperatures.
H: Indicates that the product is a hollow structural component.

Example: EN10210 S275J2H
EN10210 standard, hollow structural steel, the minimum yield strength of the pipe is 275, and the impact work tested at -20 degrees Celsius.
