Strakcha
Our cold formed steel sections commonly known as hollow sections conform to Kenya Bureau of Standards KS 02 - 104. Hollow sections are manufactured on a tube mill using high frequency induction welding technique. The strip is seam welded while round in shape and then gradually brought to the desired section in the sizing mill. The weld seam is put to a great amount cold working while being sized. This is a very severe test of seam weld and ensures that each length of hollow section is welded for maximum strengths.

SECTIONAL PROPERTIES

  1. 1. These sections have the highest possible resistance to torsion, as the entire enclosed area of the section is effective
  2. 2. Their low flat - width ratio (w/t) permits higher design stresses
  3. 3. Comparably higher moment of inertia about minor axis prevents premature elastic buckling
  4. 4. Due to availability of flat surface, joining by bolting or welding is simplified.
  5. 5. Due to high moment of inertia deflections are lower.
  6. 6. consistency in quality
  7. 7. Smooth contact and low drag co-efficiency  minimizes wind load on exposed surface
  8. 8. Availability in exact length reduces wastage of steel.
  9. 9. High strength to mass ration
  10. 10. Better fire resistance due to large heat dissipating area and lower heat absorbing area
  11. 11. Attractive shapes and clean lines add to their architectural beauty
  12. 12. Sealed end prevents internal corrosion

SAVINGS

  1. 1. Ease of erection and adaptability for prefabricated panels reduces construction time
  2. 2. Due to light weight, cost of other supporting members, foundations, handling and transportation is reduced.
  3. 3. Smaller exposed surface area reduces cos of painting and susceptibility to corrosion. Direct welding to each other avoids the need for gusset plates which saves 2 - 3% cost in steel and sledding electrodes.

ALL THE ABOVE FACTORS EFFECT SAVINGS, IN DIRECT AND INDIRECT COSTS, TO THE TUNE OF 30 - 40% COMPARED TO HOT ROLLED SECTIONS
