Cause and effect
Designed to Move With Your Trailer.
Exterior panels expand and contract as temperatures change. A trailer also flexes during use. How its panels, roof, and trim connect matters when accommodating that movement and managing exposure to the elements.
01
Exterior Panel Movement
Temperature changes cause exterior materials to expand and contract. The attachment system determines how that movement is accommodated at panels and seams.
02
Roof Connections
A one-piece roof panel still connects to the trailer around its perimeter. Those joints and the surrounding trim are important parts of the roof system.
03
Weather Protection
Sealing a trailer involves more than the visible bead of caulk. Joint design, flashing, adhesives, fasteners, and sealant each play a role.
The solution
The Aegis System.
Developed by Cross Trailers, Aegis is a proprietary wall and roof mounting system designed to accommodate flex, expansion, and contraction. Its floating panel attachment and self-flashing connections help maintain a smoother exterior and reduce reliance on sealant alone for weather protection.
01
Ripple-resistant exterior wall panels
A floating system of screwless panels and extrusions, bonded with technologically advanced adhesives for a stronger bond to the frame and increased oxidation resistance.
What it means for you
The system is designed to manage expansion and contraction, helping reduce the panel distortion that can contribute to an uneven exterior.
02
Self-flashing roof
Flashing is incorporated into the roof connection to help direct water away from the joint.
What it means for you
Water management is part of the connection’s design, reducing reliance on sealant alone.
03
Proprietary self-flashing extrusion
An extrusion is a shaped profile used at the connection. Cross’s proprietary trim profile brings the wall and roof system together with fewer screws and less sealant.
What it means for you
The trim does more than finish the edge. Its shape helps protect the connection against wind, dust, and water intrusion.
How it differs
Screwed panels vs. Aegis.
Typical screwed-panel construction
- Exterior sheets attached with rows of visible screws
- Panels pinned in place, so expansion shows up as ripples
- Seams depend on caulk to stay sealed
- Roof and trim joints sealed after the fact
The Aegis System
- Bonded panels and extrusions — no screws through the panel faces
- Floating mount allows flex, expansion and contraction
- Self-flashing trim profile with less sealant
- Self-flashing roof with a tighter bond to the frame
Daylight Makes a Difference.
One-piece Light Lid roof.
Every Cross trailer — Beta, Alpha and Echo — gets a one-piece translucent Light Lid roof. There are no seams overhead, and daylight comes through so you can see what’s inside without turning on a light.
Translucent roof built with Brawn.
