- Designed for Large-Span Roofing
- 70mm Seam Height
What Is the MR468 Standing Seam Roof System?
The MR468 Standing Seam Metal Roof System is a concealed-fixing roofing solution that uses 360° mechanical seam locking to connect adjacent metal roof panels. Unlike conventional exposed-fastener roofing, the MR468 system incorporates concealed sliding clips beneath the raised seams, reducing the need for exposed fasteners through the main roofing surface. Its 70mm finished seam height, combined with automated sealant application, is designed to improve water resistance at panel joints and reduce the risk of capillary water penetration caused by melting snow. The system also supports on-site roll forming, allowing roof panel lengths to be customized according to project requirements and reducing longitudinal end laps.

- Concealed sliding clip fixing
- On-site roll forming
- Custom panel lengths for large roofs
Structural Features of MR468 Metal Roofing
1. 360° Mechanical Locking Seam
The 360° mechanically locked seam creates a continuous connection between adjacent roof panels, supporting the system’s waterproofing and wind uplift resistance.
2. 70mm High Standing Seam
The finished 70mm rib height, together with automated sealant application, helps reduce capillary water penetration at the seams, particularly under snowmelt conditions.
3. Concealed Sliding Clip System
Sliding clips accommodate thermal expansion and contraction of metal roof panels. The sliding design extends to critical roofing connections, including ridge and gable details.
4. Transverse Stiffening Ribs
Transverse stiffening ribs are incorporated into the panel profile to reduce wind-related disturbance and improve resistance to panel deformation.
5. Pre-Punched Connection Details
Pre-punched connection details help protect the integrity of the metal sheet’s coating and plated surface during installation, supporting long-term corrosion protection.

Key Advantages of the MR468 Roofing System
Waterproofing Performance
The combination of 360° mechanical locking, high standing seams and automated sealant application helps limit water penetration through the roof panel joints. Special sealing details are incorporated at roof ridges, eaves and other critical connections.
Wind Uplift Resistance
The roofing system uses concealed clips and mechanical seam locking to secure adjacent panels. Pre-locking features provide temporary panel retention during installation before the final 360° seaming process.
Thermal Expansion and Contraction
Sliding clip supports accommodate roof panel movement caused by temperature changes. Ridge, gable and expansion joint details are designed to allow movement while maintaining the necessary connections.
Efficient On-Site Installation
On-site roll forming enables customized panel lengths, reducing the need for longitudinal end laps and simplifying installation on large roof areas.
Integrated Roofing Design
MR468 can be combined with compatible insulation, acoustic and waterproofing components to meet project-specific building performance requirements.
