In 2007, Apex Steel revolutionized the way steel is made in East Africa, and became the first local company to manufacture steel to international standards. Apex Steel makes Grade 500+ Deformed Bars - BS 4449:2005 at its technologically advanced manufacturing unit at Athi River. Locally, Kenya Bureau of Standards (KEBS) requires deformed steel bars of Grade 460.

Every meter of the deformed bars bears the trademark, 'APEX TMX' that's how customers know they are getting the genuine best steel.

Primarily deformed bars are used for concrete reinforcement in:-

  • Buildings - Commercial and Residential
  • Infrastructure - Dams and Power
  • Roads and Bridges


The permissible deviation from nominal mass per meter shall be not more than +/- 4.5% on the nominal diameters greater than 8mm, and +/- 6.0% on nominal diameters less than or equal to 8mm.


The nominal length of steel bars is 12 meters. The permissible deviation from the nominal length shall be +100/- 0mm; other tolerances may be agreed at the time of enquiry and order
