Comparison of Corrosion Resistent and Scratch Resistent Rebar.

Types of rebar Times more corrosion resistance than black rebar Scratch resistance Chloride threshold Price ranking
Black rebar X Tough enough, difficult to damage Very high No.1 lowest
Epoxy coated rebar 65X to 1762X Easily damaged, require protection and repairs Same as black rebars, very high No.2
Galvanized rebar 38X Tough enough 4 to 10 times higher than black rebars No.3
Stainless steel rebar 800X to 1500X Tough enough, difficult to damage 15 to 24 times higher than black rebars No.4 highest

Comparison of Welding and Cleaning Rebar.

Types of rebar welding cleaning
Black rebar Not all black rebar can be welded
  1. Material with a carbon-equivalent of less than 0.55 can be welded (AWS D1.4).

  1. Using low-pressure water spray.
Epoxy coated rebar Available
  1. May require preheating.

  1. Using low-pressure water spray.
  2. Make sure t to keep the surface of the epoxy coating free of damage.
Galvanized rebar Available
  1. Zinc coating of the intended weld zone should be removed at least one inch by grinding or equivalent means.
  2. Zinc coating of weld zone should be repaired after welding.
  3. Make sure proper ventilation when welding.
  4. Tack welding is not permitted.
  1. Using low-pressure water spray.
  2. Make sure t to keep the surface of the zinc coating free of damage.
Stainless steel rebar Available
  1. Preheating should not be used to avoid deterioration of the properties of the stainless steel.
  2. Before welding, dirt, grease, and oil should be removed.
  3. Can be welded with carbon steel., but the coating of carbon rebar should be removed before welding, and the coating should be repaired after welding.
  4. Tack welding is not permitted.
  1. Cleaned with mild soap, degreaser, and/or water if it is in the pickled condition.
  2. Using stainless steel brushes or commercial pickling paste to remove weld oxide and contamination.
