Industrial-Grade Bolted Structure | 300–800 kg UDL Load Capacity Per Level
Are you still risking your warehouse safety and efficiency with flimsy, wobbling boltless racks?
As a premier Chinese racking factory with decades of global export experience, Maxrac® engineers highly versatile, industrial-grade longspan shelving systems explicitly designed to thrive in demanding commercial, industrial, and logistics environments. Built with a heavy-duty bolted structural design for maximum stability, our medium to heavy-duty storage solution is trusted by European and Australian clients who place the highest value on product quality and safety compliance.
Key Features of Our Long-Span Racking Solutions

1. Zero-Wobble Bolted Structural Frame for Ultimate Safety
Unlike light-duty boltless racking that wobbles under stress, Maxrac utilizes high-strength, cold-rolled Q235 steel with secure bolted connections. This industrial bolted structure eliminates structural deformation and guarantees maximum stability, preventing warehouse tipping risks.
2. Massive Load Capacity Tailored for Industrial Performance
Engineered for heavy-duty storage, each beam level safely supports 300 kg to 800 kg Uniformly Distributed Load (UDL) as standard, with customized configurations supporting up to 1,000 kg per level. It is the ideal picking rack for bulky goods, heavy machinery parts, and automotive hardware.
3. 50mm Incremental Flexibility & Vertical Space Optimization
The modular design allows beam levels to be easily adjusted in 50 mm increments. This enables your team to adapt the shelf heights to varying inventory profiles instantly, maximizing vertical cube utilization without wasting premium warehouse space.
4. Factory-Grade Corrosion-Resistant Finish
Every upright and beam undergoes a rigorous surface treatment, including a premium powder-coated or galvanized finish. This durable coating shields the steel against rust, scratches, humidity, and daily warehouse wear and tear.
5. Modular Expansion & Mezzanine Integration
Our longspan shelving is fully expandable. You can seamlessly extend your storage rows with starter and add-on bays, or seamlessly integrate them into multi-tier mezzanine structures as your supply chain scales.

Q: Can Maxrac longspan shelving be integrated into a mezzanine system?
A: Yes, absolutely. Our industrial-grade bolted longspan shelving is engineered with the structural integrity required to support multi-tier mezzanine floor installations, allowing you to double your storage capacity using your existing warehouse footprint.
Q: What is the difference between boltless racking and bolted longspan shelving?
A: Boltless racking is typically designed for light-duty, residential, or light commercial use and is prone to swaying. Maxrac's bolted longspan shelving features a heavy-duty industrial bolted structure, offering superior load capacity (300-800kg/level), strict safety compliance, and long-term durability for heavy warehouse environments.
