FEP

Applications
Applications where FEP tubing is chosen usually require more clarity, flexibility or a lower heat shrinkable temperature than PTFE. More information on the properties of FEP resin can be found in our Tech Info section.

Advantages of FEP Tubing 

  • Lower heat shrink temperature than PTFE
  • More flexible than PTFE
  • More optically clear than PTFE
  • More lubricious than PFA

S355 European Standard Steel

Fides (China) Investment & Trading Co., Ltd

S355 EN 10025 : 2004 Standard Structural Steel Plate

S355 structural steel plate is a high-strength low-alloy European standard structural steel covering four of the six "Parts" within the EN 10025 – 2004 standard. With minimum yield of 50,000 KSI, it meets requirements in chemistry and physical properties similar to ASTM A572 / 709. Careful attention should always be placed on the specific variation of S355 required if considering substitute material. 
S355 is used in almost every facet of structural fabrication. Typical applications include:
  • Structural steelworks: bridge components, components for offshore structures
  • Power plants
  • Mining and earth-moving equipment
  • Load-handling equipment
  • Wind tower components
For more information, please contact a Leeco Steel representative.
