REBAR

Reinforcing bar or rebar is a hot rolled steel product used primarily for reinforcing concrete
structures. Meeting ASTM specifications, rebar grades are available varying in yield strength,
bend test requirements, composition.

Grade 300 / Grade 40 Sizes

 REMESH

Remesh (welded wire reinforcing fabric) provides uniform stress distribution and more
effective crack control in slabs and walls. The ease and speed with which remesh can be
installed typically save valuable installation time and costs.
• Reduces the number and size of cracks in concrete
• Permits the use of larger panels for more coverage
• Available in sheets and rolls
