In the industrial and logistical world, site cover has traditionally been viewed as a necessary expense. But as energy costs rise and operational demands increase, your infrastructure needs to do more than just sit there—it needs to perform. At Stretch Structures, we’ve revolutionized the concept of "shelter" by offering two distinct paths: the high-performance Signature Series and the rapid-utility Pro Series.
Whether you’re adding a maintenance bay to an airport hangar or a quick weather link for a loading dock, choosing the right frame and scale is critical for long-term ROI.
Use this table to quickly identify the structural grade your site requires.

The Signature Series, engineered in Italy its the definitive solution for businesses that require more than just a tent. It is a structural asset designed for permanent integration into commercial facilities.

Key Benefits:
Massive Industrial Scale: For spans reaching up to 15m wide, we utilize a massive 60mm x 150mm industrial frame profile. This provides the rigidity and wind-loading capacity required for heavy-vehicle workshops and aircraft hangars.

Your Brand, Your Way: This series is fully brandable. With an unlimited RAL color range, your tunnel becomes a high-visibility corporate asset, matching your facility's identity perfectly.
Bespoke Integration: Unlike "off-the-shelf" tunnels, the Signature Series can be custom-engineered to function as a seamless add-on to existing warehouses or to navigate complex site gradients and curves.

When your operation needs immediate weather protection without the lead times of custom engineering, the Pro Series is the industrial "fast-fix."

Key Benefits:
Instant Deployment: Arriving pre-assembled, the Pro Series is designed for speed. Simply expand the structure and secure it—no complex technical assembly required.
Optimized Internal Visibility: Available exclusively in Industrial White. This high-tenacity PVC reflects heat to keep interiors cooler and allows for maximum natural light for workers inside.
Industrial Value: By focusing on standardized dimensions and removing customization costs, we provide heavy-duty 40mm x 40mm x 2mm protection at our most competitive price point.
| If your problem is... | Your Best Solution is... | Why the Signature Series Wins |
| "I need a 15m wide workshop." | Signature Series | The 150mm profile offers the structural peace of mind that standard tunnels cannot. |
| "Our site is in a high-wind airport zone." | Signature Series | Certified Italian engineering and beefed-up frames are built for permanent exposure. |
| "I want to match my corporate colors." | Signature Series | Unlimited colors and full branding turn the tunnel into a professional building add-on. |
| "I need a fast, low-cost walkway." | Pro Series | Pre-assembled and "white-only" utility for low-stakes, sheltered areas. |
If you are looking for a permanent workshop extension that needs to match your facility’s branding and withstand high wind loads, the Signature Series is the only choice. It is a structural investment that adds long-term value to your property.
However, if you need a cost-effective walkway or a temporary cover for a loading bay and you want it ready to ship immediately, the Pro Series offers unbeatable industrial utility without the custom-build price tag.
