Dongguan Zhenyu Steel Structure Engineering Co., Ltd.

Standing Seam Metal Roofing System < Standing Seam Metal Roofing System is suitable for roofs or walls with a slope of , simple construction, firm locking, excellent drainage and anti-seepage performance, unique thermal expansion resistance and safe wind pressure resistance. Advanced secondary molding (melon peel process and fan bending process) can easily solve the problem of hyperboloid or single curve. Covering difficult problems with high quality, low energy consumption, practicality, beauty and environmental protection.
Structural Performance
z&r does not require a complete base plate for support, nor does it require complex node processing. With z&r, you can build high-performance, fully weather-resistant, beautiful roofs.
z&r The engagement method between the roof panel and the fixed base is very special. The fixed base not only limits the vertical displacement of the roof panel, but also allows relative sliding between the two along the length of the panel, eliminating the expansion of the roof panel. the stress produced. This feature allows z&r to be applied to buildings with large spans and large temperature differences between day and night.
z&r The plate shape is relatively soft and malleable, and can be suitable for architectural designs with internal and external arc shapes. For example, for the aluminum alloy plate type of z&r -, its arc-forming performance is shown in the following table:
Applicable materials for the standing seam metal roof system Features of aluminum-magnesium-manganese alloy
Special aluminum is usually used for z&r roof panels Magnesium-manganese alloy materials (), comply with
standards, or brand standards.
Special aluminum-magnesium-manganese alloy material () is a metal roofing material that is light, hard and does not rust.
The alloy grade is aluminum-magnesium-manganese alloy with moderate structural strength, weather resistance, stain resistance, and easy welding and processing. The service life is up to 10 years.
Anti-seepage and anti-leakage
z&r is fixed in a hidden way, and its standing seams are rolled together. There is no entry for rainwater on the roof panel. To ensure the complete waterproof performance of the roof, the following details are required deal with. At the cornice, use tools to bend the edge of the board downward to prevent water from flowing back into the ridge of the building. Bend the edge of the board upward to form a long horizontal embankment, and then install the ridge cover on it. Make sure that rainwater does not enter from here. Use fascia board to seal the gap between the roof and the gable surface.
In order to prevent the formation of condensation water, a thermal cut-off membrane needs to be laid between the roof panel and the bottom panel to prevent condensation water from entering the roof layer. It should be laid under the insulation layer.
Thermal insulation and sound insulation
The fixed base of z&r itself is relatively high, forming a cavity between the roof panel and the bottom panel. The insulation material can be conveniently placed inside without being compacted, ensuring that Thermal insulation effect.
z&r roofing systems can also meet acoustic requirements in building design. According to the requirements of the engineering design, a non-combustible sound-absorbing and heat-insulating layer with black tissue paper can be added, and sound-absorbing holes can be punched in the bottom plate to reduce the echo in the building.
Color coating
The aluminum-magnesium-manganese alloy coil can also be equipped with a construction-specific/polyvinylidene fluoride/fluorocarbon resin color coating and baking system. It is used in industrial and civil buildings. The life of the color coating can be up to year [depending on atmospheric environmental conditions]. With a wide range of colors, you can always choose the color you like from bright bright colors to sparkling metallic colors. Color is a particularly important factor in creating architectural aesthetics. It adopts / ratio of fluorocarbon paint and is processed by continuous pre-roller coating process. According to different colors and baking processes, the coating can be divided into two-coat and four-coat systems. The surface quality is excellent and the color is uniform. , no color difference. We can provide you with personalized colors according to your requirements.
