Hidden Metal Shelf Brackets

The design of Hidden Metal Shelf Brackets fully considers the differences in laminate materials. Its cantilever surface is equipped with longitudinal anti-slip ridges, which can effectively increase the friction and bite force with wooden or medium-density fiberboard laminates. When the laminate expands and contracts slightly due to changes in ambient humidity, these ridges can be embedded in the surface of the board by about 0.2 millimeters. According to the ASTM D143 reference method for cross-grain compression testing of wood, this embedment depth can produce a contact compressive stress of about 0.8 MPa, which is enough to resist the horizontal pushing force of the laminate in normal use. At the same time, according to DIN 68121 regulations on changes in the moisture content of furniture panels, when the relative humidity rises from 40% to 80%, the expansion and contraction rate of medium-density fiberboard can reach three thousandths. The micro-taper design on the bracket cantilever allows the layer board to freely expand and contract by about one millimeter in the length direction without generating internal stress, avoiding the risk of layer board cracking or bracket detachment. This feature is particularly important in display furniture in humid areas in the south.

 

 

The stent uses a continuous stamping process during the production stage. Each batch of products must pass double testing of salt spray and adhesion to ensure coating quality. The coating type can be epoxy resin powder or polyester powder according to customer needs, and neither contains harmful substances such as hexavalent chromium. According to the ISO 2409 crosshatch method adhesion test, the bonding force between the coating and the substrate reaches the zero-level standard, that is, there is no peeling at the crosshatch edge, which ensures that the coating will not easily fall off during repeated disassembly and assembly of the stent. In terms of reusability, the mounting screw holes of the bracket have been carburized and strengthened. According to the ISO 2702 surface hardness regulations, the surface Vickers hardness is not less than 550. After twenty times of disassembly and reinstallation, the torque retention rate of the threaded holes is still greater than 95%, while the retention rate of ordinary unstrengthened holes has dropped to less than 80%. The overall weight of the bracket is about 40% lighter than that of traditional exposed brackets. However, through the additional bottom supporting ribs, its rated load can still be maintained at 60 kilograms under a cantilever length of 200 millimeters. It takes into account both lightweight and structural strength. It is suitable for walk-in closets in high-end residences and wall-mounted display systems in boutique retail stores.
