Brentwood Steel

When you need steel products for your concrete project, we have just what you're after. AT 9 Brothers Building Supply, we provide all types of rebar, rods, wire mesh, tie wire, and other steel products for concrete reinforcement. Our company has been serving the NYC and Long Island areas for several decades and we will be happy to help you with all your steel product needs.


We offer rebar products at both our Brentwood and Riverhead locations with 20 and 30-foot rebar, along with pencil rods, threaded rods, and more. Whether you need a large supply of rebar or you just need a little bit, we're ready to help you. We also carry slab bolsters and upper continuous high chairs for your concrete reinforcement needs.

Tie Wire

When you need the right steel tie wire products for your concrete project, we have just what you’re after. We carry concrete forms, wall brackets, waler brackets, concrete chutes, and more. No matter the steel product you need, we have it.

Wire Mesh

One of the most commonly used products for concrete reinforcement, especially in swimming pool construction, is wire mesh. We carry a full line of heavy-duty wire mesh perfect for your concrete project.

Our wire mesh swimming pool lining comes in rolls 125 feet long and four feet wide. It can cover a very large area and provide you with the right reinforcement for the project. We offer both 16 and 12 gauge electrically galvanized welded mesh, which we can deliver or you can pick up at one of our Long Island locations. We also carry tie wire and wire lath.

While our wire mesh products are often associated with swimming pool construction, they can be used in other applications, as well. Commonly, wire mesh is used in stucco framing and it can even be used in more unique applications, such as building a miniature golf course.

No matter the type of steel product you need for your concrete construction project, we've got you covered. At 9 Brothers Building Supply, we provide everything you need for your upcoming construction project. Stop in at one of our two locations in the Long Island area and let us help you select the right steel and concrete products.
