Twin Slot Metal Shelving

Twin Slot Metal Shelving's column section design is ingenious. The cold-formed closed or open section matches the double slot position, which significantly increases the bending moment of inertia. Calculated based on the GB/T 6723 cold-formed steel standard, a commonly used column with a cross-sectional size of 80 by 40 mm and a wall thickness of 1.8 mm has a moment of inertia around the strong axis up to 454,000 square millimeters. When a horizontal concentrated force of 100 kilograms is applied at a height of three meters, the lateral displacement of the column top is only about three millimeters. The measured value meets the elastic stability requirements of the CECS 23 steel shelf design specification. At the same time, the length of the contact surface after the tapered pin at the end of the bracket is inserted into the slot reaches 35 mm. The contact stress is calculated to be lower than 40% of the material's yield strength. The locking force test based on the ASTM E488 standard shows that the anti-accidental slip-out ability of a single bracket is not less than 800 Newtons, ensuring that the shelves will not loosen due to vibration or collision during stacking. The structure can achieve reliable load-bearing without bolts.

 

 

The installation and expansion functions also reflect the uniqueness of the double-slot design. The two parallel slots are responsible for the load-bearing and accessory installation functions. When adjusting the layer height, you only need to tap the bracket to move it to the target slot. The assembly time of a complete set of four-layer shelves is about 12 minutes, which saves nearly half the time compared to traditional bolt connections. The second slot is compatible with dividers, label holders and hooks. All accessories share the same slot system. According to the ASTM D523 mirror gloss test, the surface electrostatic powder coating has a glossiness of not less than 75% at a 60-degree angle, and the coating thickness is 50 to 60 microns measured according to ISO 2178. It has excellent scratch resistance and decorative properties. For electronic storage environments, grounding bolt holes are reserved at the bottom of the shelf columns, which can be connected to anti-static copper wires to effectively derive frictional electrostatic charges. After simulated handling operations, the surface potential can be maintained below thirty volts, meeting the S20.20 electrostatic protection standard. Therefore, the double-slot shelves take into account structural efficiency, ease of assembly, and functional expansion needs.
