This Stainless Steel Angle Bracket is used to securely connect two panels or pipes at a standard right angle. It is commonly found in glass partitions, railings, equipment brackets, cabinets, and industrial racks. Pressed and bent from a single piece of SUS304 or SUS316 steel, it features a fine matte finish, deburred edges, and a smooth feel. Installation requires only expansion screws or machine screws, ensuring precise positioning and efficient assembly. Users experience structural stability, reduced vibration, and a clean, visually appealing connection, making it ideal for applications requiring reliable right-angle positioning and long-term load-bearing performance.

High-Strength Load-Bearing

The corner brackets are press-bent from 2.7mm thick stainless steel. The 90-degree bend area is cold-worked and hardened, increasing its strength by approximately 15%. A dual-hole arrangement distributes shear forces. Tested with standard M6 fasteners and two-point mounting, they withstand static pullouts of up to 4.5 kN and lateral shear loads of up to 3.2 kN. They can withstand the sustained and impact loads of railing ends and partition corners, ensuring the connection joints will not loosen or shift during long-term use.

Precise Dimensional Control

The bend angle is controlled by a mold to within ±0.3° of 90°, and the hole spacing and diameter tolerances are controlled to ±0.15mm. This ensures high hole alignment during installation, reducing the need for secondary hole expansion and correction. Dimensional stability ensures better squareness and verticality, more uniform joints between glass and panels, and more balanced stress distribution throughout the structure, significantly reducing edge cracking and fastener shear caused by misalignment.

Seismic and Shock Resistance

The matching of the bend radius and plate thickness ensures a smooth stress transition within the corner arc, minimizing impact energy concentration. Vibration table testing with a sweep frequency of 5 Hz to 25 Hz showed that the tightening torque dropped to less than 5 after two hours. For applications like door openings and passageways subject to frequent opening and closing, or heavy foot traffic, the angle brackets maintain stable connections, reducing the possibility of loosening of hinges and enclosures, and reducing the need for subsequent maintenance.

Easy Installation

The double countersunk holes accommodate M6 to M8 fasteners. The depth and angle of the countersunk holes match those of common screw heads. After installation, the nuts sit flush with the surface, minimizing visible interference. Each joint typically requires two angle brackets and four screws, and a skilled worker can complete the assembly in approximately two to three minutes. Standardized hole locations eliminate the need for on-site drilling or welding, making it suitable for renovations of existing spaces and quick turnaround projects.

Safety

The matte satin finish softens reflections and resists scratches, complementing a modern, minimalist style. The 0.3 to 0.5 mm chamfers on all four sides provide a smooth feel and minimize the risk of scratches. The flatness of the contact surface with glass and aluminum profiles is better than 0.2 mm, and it can be equipped with thin rubber pads to achieve electrochemical isolation and anti-slip, which not only optimizes the continuity of the appearance, but also takes into account user safety and structural stability.

Glass Partition Corners

At the corners of office or bathroom partitions, a pair of angle brackets, placed above and below, work with expansion sleeves and stainless steel bolts to securely lock two panes of glass or profiles at right angles. Field tests show that a 2.4-meter-high partition moves less than 3 mm under a wind pressure of 0.4 kPa, resulting in minimal change in the door gap, effectively ensuring privacy and sound insulation while maintaining an aesthetically pleasing overall shape.

Railway and Enclosures

Using angle brackets at the connection points between the end posts and crossbars of balconies or stairways allows for weld-free joint construction. After manually applying an 800-N horizontal load, the handrail recovered less than 1 mm, demonstrating that the angle brackets provide sufficient rebound stiffness. This method facilitates later replacement and local maintenance, making it suitable for railing systems in residential, school, and public buildings.

Equipment and Racks

Laboratory duct supports, lightweight shelving, and control cabinet frames often require reliable right-angle brackets. Corner brackets connect to square tubes using rivet nuts and machine bolts, capable of withstanding the vibration and cyclic loads of fan startup and shutdown within the cabinet. After 10,000 continuous startup and shutdown cycles, the tightening torque retention rate exceeded 90%, demonstrating its stability and reliability in the long-term operation of the equipment cabinet.

Home Decoration

In custom furniture, display stands, and light box frames, corner brackets enable rapid assembly, ensuring right angles and consistent alignment. For example, a 2m x 1m display frame, with its four corners connected using corner brackets, maintains geometric tolerances within 1mm even after transportation and multiple assembly and disassembly. This facilitates repeated exhibition setups, speeds up installation, and reduces waste costs.

Routine Cleaning

Wipe the corner brackets and surrounding areas monthly with a neutral detergent and a soft cloth to remove dust and salt spray residue, then rinse with clean water and dry. Regular cleaning prevents the accumulation of chloride ions and metal dust on the surface, maintaining the integrity of the passivation film, and maintaining a long-lasting matte finish and corrosion resistance. This is particularly suitable for coastal environments and kitchens.

Corrosion Prevention

For projects near sea breezes, swimming pools, or chemical storage areas, it is recommended to apply a thin layer of wax-free protective oil to the corner brackets and fasteners every three to six months. This oil film reduces water film tension and reduces the initiation of pitting corrosion. For outdoor SUS304 joints, installing insulating gaskets and sealing strips can also inhibit electrochemical corrosion.

Tightening Re-inspection

After commissioning, it is recommended to re-tighten the screws according to the designed torque every 30 days, 90 days, and every six months. Vibration, temperature fluctuations, and frequent use can cause micro-loosening, and periodic re-inspections can prevent potential problems in the bud. Torque markings can be applied to critical load-bearing points to create a traceable maintenance record.

Damage Repair

If scratches or flying particles appear on the surface, first remove them with a non-metallic scraper. Then, lightly abrade along the grain with an 800-1200 grit abrasive disc. Restore the gloss with a stainless steel care agent. Deformed or damaged angle brackets should be promptly replaced. Also, check the integrity of the supporting bolts and base material to ensure that the joint continues to meet load-bearing and safety requirements after restoration.
