Explore our highly versatile, light-duty to medium-duty boltless racking configurations engineered for residential, commercial, and warehouse applications.
The modern logistics and home storage industries demand structural solutions that balance mechanical rigidity with rapid assembly capabilities. The gourd hole (or keyhole rivet) racking system represents a milestone in storage engineering. By leveraging the physical principle of interlocking tapered structural rivets into specialized gourd-shaped slot profiles, these shelves eliminate the need for traditional nuts, bolts, and specialized tools.
Under vertical load distribution, the downward gravitational force acts to push the rivet deeper into the narrow slot of the gourd hole. This mechanical action creates a tight wedge fit, which actively increases structural stability as load margins rise. This design is highly valued for retail displays, garage spaces, and multi-tier e-commerce fulfillment hubs.
Shenzhen Shibang Storage Rack Co., Ltd. (Established 2015) is a leading designer and manufacturer of specialized structural racking systems. Operating from a state-of-the-art 32,000-square-meter facility, we provide structural design, precision cold-roll forming, and global delivery solutions for B2B enterprises worldwide.
With over 12 years of industry expertise and 8 years of dedicated export experience, our products are distributed across North America, Europe, Australia, and Southeast Asia. Supporting a global client base including 3PL providers, industrial distributors, and e-commerce fulfillment networks, our annual export revenue exceeds $18 million.
Our upright posts are cold-rolled from high-strength carbon steel, maintaining profile tolerances within ±0.05mm. The pitch of the gourd holes is engineered for standard increments, allowing flexible shelf adjustments.
We source raw steel coils directly from tier-1 manufacturers. This guarantees consistent yield strength, elastic modulus, and surface preparation to ensure optimal adhesion of electrostatic powder coatings.

Take a closer look at our automated, highly optimized production stages at Shenzhen Shibang Storage Rack Co., Ltd.
Analyzing load distributions, material fatigue limits, and advanced protective coatings for the next generation of industrial shelving.
By using finite element analysis (FEA), our R&D engineers have optimized the slope angles of the keyhole taper. The revised geometry reduces stress concentration factors by up to 22%, distributing force evenly along the structural uprights.
Every structural part undergoes an automated 7-stage chemical pre-treatment wash. This includes alkaline degreasing, hot rinsing, zinc-phosphating, and deionized water rinsing to ensure maximum protection against corrosion.
Our structural components are made from Q235B cold-rolled steel, offering yield strengths of 235 MPa and elongations up to 26%. This enables our shelves to consistently handle loads from 100kg to over 350kg per level.
Our boltless gourd hole racks enable e-commerce operations to quickly adjust shelving configurations without using heavy tools. The open-access design allows for fast order picking, direct carton storage, and clear barcode scanning from any direction.
Industrial garages demand stable storage structures that resist humidity, grease, and impacts. Our heavy-duty steel shelves feature a durable electrostatic powder coating that protects components in demanding automotive and fabrication settings.
Storage infrastructure needs to be versatile. A single warehousing system must adapt to changing SKUs, varying load profiles, and seasonal inventory peaks. Shibang's gourd hole racking solutions offer the flexibility required by modern industries.
For large-scale retailers and distribution centers, our boltless design significantly reduces setup times during floor reconfigurations. By utilizing intermediate tie bars and double-rivet support beams, our shelves maintain structural integrity under heavy loads, ensuring employee safety and operational continuity.
Our engineering team can customize heights, depths, and overall load capacities to match specific floor plans. We focus on maximizing vertical storage space while keeping floor areas clear for material handling equipment.
How Shibang aligns with international safety regulations, strict cargo logistics, and procurement standards.
Our quality control processes include raw steel tensile testing, ultrasonic weld inspection, static load evaluation, and salt spray testing. This ensures full compliance with ISO 9001:2015 and CE standards.
Every boltless unit is flat-packed to maximize container load efficiency. This packaging method helps lower transcontinental shipping costs and protects components during transit.
We assist distributors worldwide with technical documentation, load capacity charts, assembly instructions, and customs clearance procedures, ensuring a smooth procurement process.
Answers to common technical, manufacturing, and shipping questions for global B2B buyers.
Our standard light-duty configurations support 100kg of uniformly distributed load per level. For higher demands, we customize beam profiles and steel thickness to achieve load ratings exceeding 250kg per level.
Our quality control team of 35 inspectors performs incoming raw material testing, online automated dimension checks during roll forming, and regular powder coat adhesion tests to maintain consistent quality.
Yes. We offer customization for steel thickness, upright post heights, shelf depths, shelf materials (MDF, steel, or wire mesh), and custom powder coat colors to match your brand requirements.
Our standard manufacturing lead time is 20 to 30 days from deposit receipt and design approval. We work closely with major shipping lines to optimize container utilization and manage export logistics.
