Rebar

Hayward stocks a wide variety of rebar sizes, grades, and finishes.  We are committed to have what our customers need, when they need it.  Hayward has access to rebar across the US, and internationally if necessary.  We can find what you’re looking for, whatever it is.

Rebar is available in grades and specifications that vary in yield strength, ultimate tensile strength, chemical composition, and percentage of elongation.
The grade designation is equal to the minimum yield strength of the bar in ksi (1000 psi) for example grade 60 rebar has a minimum yield strength of 60 ksi. Rebar is typically manufactured in grades 40, 60, and 75.

#3 reinforcing bar or “rebar” is primarily used in swimming pool frames, road and highway paving, and patio and driveway construction. It also has important applications in the vineyard industry, as it is ideal for training rootstocks to grow as designated by its trellising system. The expansion coefficient of the carbon-steel composite compares favorably with the characteristics of industrial-grade concrete. In metric measures, #3 rebar is known as “10MM.”

#4 rebar is a commonly used high-grade reinforcement product with widespread applications in the residential and light commercial construction industries. In particular, #4 reinforcement steel is used to pave roads and highways, and in certain climates, it can also be used to build swimming pool frames. Often trusted as a strengthening material in slabs, piers, columns and walls, #4 rebar is known as “13MM” in the metric system.

The primary applications of #5 rebar include pre-cast masonry for use in highway and bridge construction, as well as foundation grade beams, footings and tilt-up walls. #5 reinforcement steel also has widespread uses in the light commercial and residential construction industries, including patio decks, retaining walls and caissons. In metric circles, #5 rebar is known as “16MM.”

#6 rebar is ideally used in concrete reinforcement applications. Specifically, this reinforcement bar is found in foundation construction and repair, retaining walls and tilt-up walls. It is also used as a strengthening compound in caissons, pre-cast masonry products and deck-grade beams. Finally, #6 rebar is occasionally used in the road and highway construction industry in the creation and maintenance of new and existing roadways. “19MM” is the metric equivalent of #6 rebar.
