MR468 metal prefabricated roof system consists of composite panels, which are made of roll-forming metal sheet (galvanized steel sheet, Super Galum, and color-coated steel sheet) and thermal insulation materials, back sheets, and other accessories. The system is suitable for roofs with a span of over 20m.
Product Description

Performance  features

1.Hidden mounting brackets, no screw penetration on the surface

2.The bracket features a sliding structure, which allows a slight movement caused by thermal expansion and contraction of the metal panel after engagement, thereby preventing structural damage caused by stress buildup that cannot be released.

3.Roof panels, fasteners, and other accessories are pre-punched for accurate alignment and neat finishing.

4.The panel features vertical ridges on one side and corresponding grooves on the other for engagement. Ridges are 70mm tall, which gives it a good drainage ability and our adhesive equipment can provide pre-applied sealing adhesive for joints to prevent leakage under any harsh weather conditions

5.Experienced engineers working with equipment that is safely transported in crates to guarantee reliable on-site installation.

Operable Unitized Metal Curtain Wall System
 
The openable integrated metal curtain wall system successfully incorporates natural ventilation into solid metal panels, moving beyond the conventional approach of placing ventilation openings only within glazed sections. This is achieved through systematic design and prefabricated construction. While fully preserving the aesthetic integrity of the building facade, the system introduces a natural ventilation experience within traditionally non-transparent cladding areas. This significantly enhances indoor environmental comfort and health, achieving a unified harmony of architectural design, practical function, and user-centric experiential quality.
