Self-Storage Flooring Systems and Decking Solutions

Self-storage facilities demand efficient use of vertical space without compromising safety or durability. Unistor’s engineered flooring systems are designed to maximise floor area, streamline installation, and provide consistent structural strength across multiple levels.

Our Level-Span decking systems support high load capacities and integrate seamlessly with mezzanine structures, partitions, and wall systems. They provide a solid, even platform that ensures long-term performance and minimal maintenance over the facility’s life.

With a proven track record across industrial, logistics, and storage projects, Unistor’s engineering team understands how to balance strength, safety, and usability in every design.

Level-Span corrugated metal decking is the preferred choice for self-storage projects where safety, efficiency, and visual quality are critical. Manufactured in a range of gauges and profiles, it can be tailored to specific load requirements, spans, and design conditions.

For construction efficiency, Level-Span can be supplied pre-punched for use with the Invisi-Loc underside fastening system, allowing faster installation and a clean, screw-free finish. This system reduces onsite waste and ensures a uniform, professional appearance.

Developers also benefit from finish options including galvanised and bright white coatings. The white underside enhances light reflection, improving internal visibility within storage corridors and helping operators reduce energy use. Combined with ResinDek® or other surface systems, Level-Span provides a complete, high-performance flooring solution that is both functional and visually consistent.

Self-storage environments are used daily by both customers and staff. Floors must be not only structurally sound but also safe and comfortable to walk on. Level-Span’s corrugated steel design provides superior strength and rigidity, reducing vibration and noise. The reflective finish improves visibility and contributes to a cleaner, more secure atmosphere for tenants.

Unlike timber or concrete, Level-Span does not crack, splinter, or require frequent sealing. It resists corrosion, maintains a level surface, and can be installed quickly, helping developers meet tight build timelines without compromising quality.

Every Unistor system is designed to meet the practical demands of large-scale construction. Our in-house engineering and drafting teams develop precise solutions based on load, span, and layout requirements. By working directly with builders and architects, we ensure that each self-storage facility is designed for long-term reliability and minimal maintenance.

Level-Span’s modular nature simplifies both new builds and extensions, making it an ideal choice for operators looking to scale their facilities in the future. The decking’s strength and uniformity support flexible partition layouts, meaning it can adapt as storage needs evolve.

For more than three decades, Unistor has delivered structural and mezzanine flooring systems for some of Australia’s most complex industrial and commercial environments. Our experience extends from warehousing and logistics through to retail, manufacturing, and storage.

By combining design expertise, local manufacturing partnerships, and hands-on project delivery, we help clients build smarter, faster, and with greater confidence. Each project is supported by end-to-end service, from early-stage engineering to final installation and inspection.
