Steel rebars

Product information

Steel reinforcement rebars are used to improve the tensile strength of the concrete, since concrete is very weak in tension, but is strong in compression. Steel rebars are also used because elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals to that of concrete.

Welded fabric is a joined grid consisting of a series of parallel longitudinal steel wires with accurate spacing welded to cross wires at the required spacing, while welded reinforcement steel is steel bars cut, bended and welded together to satisfy required parameters.

Included products in this EPD

"SERFAS” Ltd produces two main types of steel rebars:
  • Reinforcement rebars and bendings;
  • Welded fabric and welded reinforcement steel.
Weldable steel for the reinforcement of concrete has become subject to the European Standard, EN 10080. EN 10080 gives no actual specification or figures; that is left to the National Standards (NS 3576-3; SS 212540; EN1992-1-1; SFS 1300) Technical classes (B500NA/B500NC/K500B-T/K500C-T/K500C-KR/B500A/B500B/B500C) are defined by specific values of properties like yield strength, elongation, and etc.

Welded fabric and welded reinforcement steel are made according to the National and European Standards (NS 3576-4; EN 10080; SS 212540; EN1992-1-1 DK NA; EN ISO 17 660-1; EN ISO 17660-2) depending on destination market. Technical classes (B500A; NK500AB-W; NK500B-K; S500A) are defined by specific values of properties like yield strength, elongation, etc.
