25 roof system, the use of special legislation and automatic occlusion device side, the two strips along the whole length of the prefabricated plate side stand up, leaving the roof by a double folding lock connection as a whole, is fully enclosed metal roofing system . 25 fastener roof system is divided into: fixed fasteners and slide fasteners. System board rib is usually high 25mm. The plate for the roof surfaces and more complex shapes more easily achieved in terms widely used in villas, clubs, museums, galleries, etc. 

 65 roof system so the most prominent place in a multi-functional, multi-component magnesium manganese alloy roof system, primarily used in large-span lightweight composite roof structure of space systems. Support of this point in the production of single roofing system, hyperbolic, multi-dimensional surface of the roof system is the most successful plate. System flexibility and product diversity for the building roof, wall and overall envelope to provide the ideal solution. Rich surface (primary hammer layer, polyester pre-roll coating PE, PVDF pre-roll coating PVDF), make your every project has excellent functionality and great aesthetics, acoustics. 
 65 roof system has a sustainable solution that can help you create also has excellent functionality and stunning visual effects with the roof and walls. 
 System advantages: weathering performance, long life; self-supporting, performance and reasonable force; roof drainage superior performance, without affecting the slope; construction performance clearly, according to the functional requirements, a reasonable combination; their effective lightning protection performance; economic rationality installation simple and convenient, short construction period; unlimited expansion, the structure does not produce stretching stress; not waterproof glue, exposed roof without piercing screws; sealing performance, effective sound insulation; easy maintenance, environmentally friendly recyclable.
