Textured Epoxy Coated
Reinforcing Steel
The next generation of corrosion resistant reinforcing bars is here.
New ASTM 1124 is a major advancement in durability and longevity. This technology provides bond performance equal to uncoated reinforcement while providing the corrosion protection of ASTM A775 epoxy coating.
THE A1124 PROCESS:
Immediately following application of the base epoxy coating to the heated reinforcing bar, a new second layer of the epoxy coating with a controlled textured surface is sprayed on.
These two epoxy layers gel and cure simultaneously and are chemically bonded to one another during the curing process, forming a single, cross-linked epoxy coating system.
Studies are proving that Textured Epoxy Coating (TEC) has Significant advantages over ECR:
SUSTAINABLE:
DEVELOPMENT LENGTH:
A1124 has a development length equivalent to uncoated reinforcement bars.

CRACK REDUCTION:
Narrower cracks mean less chloride ingress — A1124 halved crack widths versus A775.
FLEXIBILITY:
ASTM A1124 meets the same flexibility requirements as ASTM A775, allowing reinforcing bars to be bent to shape after coating without coating damage.
STABLE IN CONCRETE:
Epoxy does not require chromate passivation or admixtures to prevent bond-reducing reactions in curing concrete.
DAMAGE TOLERANCE:
A1124 has an enhanced damage-tolerant surface that protects the A775 epoxy base layer.
