Glostar MR468 360° Standing Seam Metal Roof Panel System – Large Span, Weatherproof & Thermally Adaptive
The MR468 is a 360° standing seam locking mental roof system engineered for large-span industrial and commercial buildings. With a post-seam rib height of up to 70mm and fully automated inline gluing technology, it delivers exceptional waterproofing, airtightness, and wind-uplift resistance.
Available with on-site roll-forming, panels can be cut to any required length—eliminating transverse laps and reducing both installation cost and technical complexity.

The MR468 standing seam roof system is designed to answer the most critical demands of modern large-span roofing: waterproofing, wind-uplift resistance, thermal expansion accommodation, and long service life with minimal maintenance.
Unlike conventional roof panels that rely on exposed fasteners or simple lap joints, MR468 uses a fully mechanical 360° seam lock, reinforced by automated butyl sealant applied inline. The result is a roof enclosure that maintains its performance integrity across extreme weather, wide temperature swings, and building settlement.
Formed on-site by a fully automated seam-locking machine. Creates a continuous watertight joint along the entire panel length.
High rib combined with automated inline butyl gluing prevents capillary water migration in extreme climates.
Hidden-clip sliding bracket accommodates thermal movement up to 65 m on a single slope without stressing the seam.
Mobile production equipment forms panels on site — no transverse lap joints, faster installation.

Q: What is the minimum roof pitch for MR468?
MR468 is suitable for very low pitch roofs (as low as 1.5° or 1:40 slope) due to the 360° seam lock and high rib profile, which prevent water ingress even under ponding or blowing rain conditions. Confirm with our technical team for your specific climate and building geometry.
Q: Can MR468 be installed on curved roofs?
Yes. The panel can be roll-formed to a curved profile (barrel vault or tapered bay shapes) within the material's forming limits. Please provide your design drawings for a feasibility assessment.
Q: What warranties are available?
We provide product quality warranty against manufacturing defects. Coating performance warranty depends on the selected finish (PVDF typically carries a 25-year chalk and fade warranty from the coating supplier). System waterproofing warranty is available for contracted installation projects. Please contact our sales team for project-specific warranty terms.
Q: Is MR468 compatible with photovoltaic (solar panel) mounting?
Yes. The MR468 seam profile is compatible with standard standing-seam solar clamps (S-5! and similar). No roof penetration is required for solar mounting. Confirm load requirements with your structural engineer before finalizing the PV layout.
Q: What is the MOQ and lead time?
MOQ and lead time depend on project quantity, coil specification, and finish. Typical production lead time is 20–30 days after order confirmation and coil material availability. Contact us with your project BOM for a specific quotation.
