Steel Threaded Rod 34 mm –

جاويط (تيش) حديد مقاس 34مم

Description

• Grade

  Regardless of the endless variety of grades and specifications of All Thread, for the Structural and Miscellaneous Steel Fabricator it can be narrowed down to:

  Carbon

  • A307 Low Carbon Steel (F1554 A-36)
  • Grade 55 (F1554 GR-55 S-1)
  • A449
  • B-7 (F1554 A-105)

  Stainless

  • 302, 303, 304 (For threaded rod purposes these are often combined)
  • 316
  • 316L

  Note, of the seven grades shown above, only 3 are covered by ASTM F1554.

  Coating

  All of the carbon steel threaded rods are available in plain steel, zinc blue or zinc yellow and hot dip galvanized. This is another area where the specifications cross lines. ASTM F1554 calls for coatings to be applied after all fabrication is complete. When Galvanized threaded rod is cut to specific lengths as required by the customer the cut ends, along with the chamfered area are not galvanized. This is easily repaired with Cold Galvanize Compound but its viability as a galvanized stud has changed. To strictly adhere to the specs the rod should start out with a plain finish, be cut to size, chamfered and then finally coated as a last step.
