Epoxy Coated Steel

Epoxy coated steel rebar

Epoxy coated rebar or corrosion-resistant rebar is used instead of conventional reinforcing bars to strengthen the concrete and protect against corrosion. The epoxy coating is applied in a factory to the steel prior to shipping to ensure corrosion resistance. Epoxy-coated steel reinforcing bars (rebar) may be used in any concrete subjected to corrosive conditions. These may include exposure to deicing salts or marine waters.

Overview

Rebar is necessary to compensate for the fact that whilst concrete is strong in compression, it is relatively weak in tension. By casting rebar into concrete, it is able to carry tensile loads and so increase overall strength.

Working Properties

High Strength, Ductility and Weldability

Main Uses

• Primary reinforcement: Used to provide resistance to support design loads.
• Secondary reinforcement: Used for durability and aesthetic purposes by providing localised resistance to limit cracking and temperature-induced stresses.
• Provide resistance to concentrated loads, spreading it through a wider area.
• Assist other steel bars in accommodating their loads by holding them in the correct position.
• External steel tie bars to constrain and reinforce masonry structures, sometimes as a means of building conservation.
• Reinforced masonry: Some masonry blocks and bricks include voids to accommodate rebar to carry tensile loads. The rebar is secured in place using grout.
