Keep Material in the Bay - Not on the Wall

Welcome to Flash-In® by RSG Structures

A Smarter Approach to Safer Storage

Traditional flashing systems have long presented hidden risks within material storage bays.

Designed to sit on top of walls and slope backwards, they often allow material to build up where it shouldn’t—directly on the wall itself. Over time, this leads to excessive loading beyond the wall’s intended design capacity, compromising structural integrity and reducing safety margins.

As material accumulates, the flashing itself can become damaged under the weight. This not only reduces its effectiveness but also allows material to fall behind the wall, creating unseen hazards. In many cases, this trapped material has been linked to fires that are difficult to detect and even harder to extinguish—posing a serious risk to both facilities and personnel.

Flash-In®, developed by RSG Structures, has been engineered to solve these challenges by completely rethinking how flashing should work.
Unlike traditional systems, Flash-In® is designed to lean inward into the storage bay. This innovative approach actively pushes material back into the bay, preventing build-up on top of the wall entirely. As a result, walls cannot become overloaded, and the risks associated with hidden material are significantly reduced.

For added safety, Flash-In® is finished in a bright yellow coating, ensuring clear visibility for operators. If the flashing cannot be seen, it provides an immediate visual indication that material levels are too high.

Originally designed for block walls, Flash-In® has evolved into a versatile system suitable for a wide range of wall constructions.
Modern, effective, and built for safety—Flash-In® keeps materials where they belong and helps bring your facility firmly into the 21st century.

Stop Hidden Risks in Your Storage Bays

Traditional flashing can create unseen problems, allowing material to build up on top of walls, overload structures and fall into areas that are difficult to monitor.

Flash-In® changes this completely. By leaning inward and pushing material back into the bay, it prevents build-up, protects your walls and creates a safer, more controlled storage environment.

Why Choose Flash-In®?

Flash-In® has been developed to solve a common but often overlooked problem in material storage bays. Traditional flashing systems can allow material to build up on top of walls, creating hidden risks, increasing structural load and reducing overall safety.

By rethinking how flashing works, Flash-In® provides a practical, engineered solution designed for modern storage environments.

Eliminates Material Build-Up

Traditional flashing slopes backwards, allowing material to sit on top of the wall. Flash-In® is designed to lean inward, actively pushing material back into the bay and preventing build-up where it shouldn’t occur.

Prevents Dangerous Overloading

By keeping material off the wall, Flash-In® helps prevent excessive loading that can place strain on structures and reduce safety margins over time.

Reduces Hidden Risks

Material that builds up behind walls can go unseen, creating fire hazards and operational risks. Flash-In® removes this issue by keeping material visible and contained within the bay.

Highly Visible Safety Design

Finished in a bright yellow coating, Flash-In® provides a clear visual indicator for operators. If the flashing is not visible, it signals that material levels are too high and action is needed.

Built for Real-World Use

Designed for practical site conditions, Flash-In® is robust, effective and suitable for a wide range of environments. Originally developed for block walls, it can now be adapted for use across multiple wall types.

Improves Safety and Longevity

By reducing loading, preventing damage and controlling material placement, Flash-In® helps protect your infrastructure, improve operational safety and extend the life of your walls.
