Corner Strut Channel Brackets
Zinc-plated steel brackets are more corrosion resistant in wet environments than powder-coated and painted steel. Galvanized steel brackets have better corrosion resistance in wet environments than zinc-plated steel and can be used outdoors. 304 stainless steel brackets are more corrosion resistant than galvanized steel. They also have good chemical resistance. 316 stainless steel brackets have excellent resistance to chemicals and salt water. Aluminum brackets are about half the weight of steel and resist corrosion in wet environments. Fiberglass brackets are nonconductive with good resistance to chemicals and salt water. They're about half the weight of aluminum.
Brackets with fasteners included come assembled with screws and nuts with springs, so you can install them quickly.
