Support Brackets for Every Project

No matter what type of project you are designing, developing or constructing, we have the dependable and versatile support brackets and metal countertop brackets you need. Each one of our metal bracket options has their own unique capabilities and special features. Browse our impressive selection to get started.

What Type of Metal Shelf Brackets Are Strongest?

A&M Hardware’s strongest shelf and countertop support brackets are the 2.0 Extended Concealed Brackets. These steel brackets include an upper extension above the support arm for additional strength while remaining hidden beneath the supported surface.

In testing, the EC9(2.0) Extended Concealed Bracket reached 7,960 pounds per pair before deformation. Load performance varies by bracket size and projection. For example, the EC12(2.0) reached 3,100 pounds per pair, while the longer EC24(2.0) reached 1,830 pounds per pair. These results make the Extended Concealed 2.0 series a strong option for countertops, kitchen islands and other installations requiring substantial concealed support.

The strongest bracket for a particular project still depends on the countertop or shelf material, projection depth, expected load, bracket spacing, wall construction and installation method. A&M Hardware can help contractors and designers select the appropriate bracket and size for each application.

Both are imported steel brackets with a black powder-coated finish.

Concealed Brackets

Brackets installed behind drywall or cabinetry to support countertops, shelves, and other surfaces while keeping the mounting hardware out of sight. Across the 1.0-inch and 2.0-inch models tested, loads to deformation ranged from 350 to 7,960 lbs per pair. These steel brackets are primarily imported, with selected U.S.-made concealed models also available. Powder-coated color options include black and white, with gray and almond offered on selected 2.0-inch sizes.

Hybrid Brackets

Versatile brackets that can be installed as either surface-mounted or concealed supports, making them useful for countertops, kitchen islands, desks, workstations, and shelves.

Both styles are imported metal brackets available exclusively with a white powder-coated finish.

Floating Vanity & Heavy-Duty Hybrid Brackets

Heavy-duty supports designed for floating vanities, countertops, workstations, and other surfaces requiring strong reinforcement with minimal visible hardware. The floating vanity bracket tested to deformation at 1,100 lbs, while heavy-duty hybrid brackets tested from 1,350 to 1,700 lbs per pair. Both styles are listed as imported brackets.

Island Brackets

Heavy-duty supports designed for kitchen-island, breakfast-bar, and countertop overhangs without adding obstructive floor-mounted legs. Test results ranged from 350 to 3,250 lbs at deformation, depending on the bar length and whether the long or short arm was tested. These imported brackets use 1/2-inch-thick, 2-inch-wide steel support bars.

Surface-Mounted Brackets

Low-profile brackets mounted directly to framing to support floating shelves and similar surfaces without opening the wall for concealed installation. Tested loads to deformation ranged from 500 to 2,000 lbs per pair, depending on the bracket’s size and material. These imported brackets are available in black- or white-powder-coated metal, brushed stainless steel, or brushed aluminum. The stainless-steel and aluminum versions have a clear finish.

Stair Tread Brackets

Heavy-duty metal brackets designed to support industrial-style stair treads while creating an open, streamlined appearance. The ST10 stair tread bracket reached a tested load to deformation of 10,000 lbs per pair. It is an imported metal bracket offered with a black powder-coated finish.

Cleat Support Brackets

Long, low-profile supports installed along the back edge or side walls beneath countertops, desks, and workstations. They provide added reinforcement between primary brackets and include offset attachment holes for securing the supported surface. These imported metal brackets are available with a black powder-coated finish.

Heavy-Duty Adjustable Support Brackets

Adjustable metal supports that allow shelf or work-surface height and placement to be customized for workstations, storage areas, garages, and similar applications. The tested 12-inch and 18-inch horizontal-arm models reached loads to deformation of 2,400 and 1,800 lbs per pair, respectively. These imported metal brackets are available in black or white finishes.
