Structural Integrity • Cost Effective • Crack Resistance • Environmental Design
Other Corrosion products
- Stainless Rebar
- Good anti-corrosion product.
- Some grades of stainless steel will corrode (see EIG study).
- Approximately 8 times the cost of epoxy rebar.
- Stainless rebar generally not made from recycled materials and may not qualify for LEED MR4.1
and MR4.2 (2 points). - Stainless rebar generally does not originate regionally and may not qualify for LEED MR5.1
and MR5.2 (2 points). - Fabrication equipment must be clean of “black steel” shavings otherwise the product will corrode. It is preferable to have dedicated equipment.
- Scrap can be a problem due to the high initial cost. Care must be taken to limit the amount of scrap loss and heighten security is recommended (i.e. minimize theft).
- GFRP (“Glass Fibre Reinforced Polymer”)
- No provincial or ASTM standard.
- No long term evaluation.
- Cannot be fabricated by fabricator. Loss of revenue to the fabricator as a distributor and any design changes at the sight may be delayed.
- Low modulus of elasticity. Failures are catastrophic generally meaning that structures have to be overdesigned.
- Decrease in strength at the bends, requires the reinforcing bar to be over designed.
- Cracking. Because of the lack of elasticity, when cracks occur they are generally larger.
- Higher cost. Significantly higher cost than epoxy rebar for a given project. Further, due to the "overdesign“ requirement, all applications must be evaluated on a case by case basis.
- GFRP generally not made from recycled materials and may not qualify for LEED MR 4.1 and MR 4.2 (2 points).
- GFRP generally does not originate regionally and may not qualify for LEED MR 5.1 and MR 5.2 (2 points).
- MMFX
- No provincial standard.
- Actively corrodes (EIG study).

. - Marketed as higher yield steel. Loss of revenue to the fabricator as less steel is used.
- Company has filed for Chapter 11, CCCA bankruptcy.
