Magnesium manganese metal roofing system design factors to be considered
Bearing
Withstand construction loads, rain, dust, snow pressure, maintenance load. Magnesium manganese metal roof plate load-bearing performance and the cross-sectional characteristics, the strength of the material thickness, the force transmission means, purlins (Vice purlin) spacing on.
Wind pressure
Local maximum wind pressure resistance, magnesium manganese metal roof will not be pulled off the negative air pressure. Wind resistance with aluminum-magnesium and manganese metal roof bracket of the buckle together, the bracket density.
Noise
Reached from the outside to prevent the sound from the indoor or outdoor indoor spread. Manganese in magnesium metal roofing insulation layer of fill material (usually cotton as insulation), the effect of noise level in magnesium manganese metal roof on both sides of the sound intensity difference in decibels. Sound insulation and sound insulation material density, thickness. It should be noted: insulation material for different frequencies of sound barrier effect is not the same.
Seepage
To prevent rainwater infiltration from the outside to the inside magnesium manganese metal roof. Rain water mainly through the gap or overlap the node into the aluminum-magnesium manganese metal roofing. Impervious to achieve the function, need to screw the mouth after using the gasket fixed with hidden, in the board's lap with sealant or welding process, it is best to use a long-pass plate to eliminate overlap, in a variety of node parts of the abdominal distension tight waterproofing treatment.
Lightning
To lead to ground lightning, thunder and lightning to prevent breakdown of magnesium manganese metal roof into the interior.
Lighting
Improve indoor lighting through skylights during the day, to save energy. Magnesium manganese metal roof in a specific location or arrangement of lighting glass lighting board should consider the life of roof metal roof with the coordination of magnesium manganese, magnesium and manganese in the metal roof skylights junction waterproofing treatment.
Safety devices
Manganese in magnesium metal roof with fixed security system to protect construction workers and maintenance personnel.
Anti-icicle
Rain and snow at the eaves to prevent icicles formed at.
Beautiful
Magnesium manganese metal roofing metal surface with good texture, pleasing color.
Control thermal expansion and contraction
Control the contraction of magnesium manganese metal roof displacement and direction. Ensure that the magnesium manganese metal roof in a large temperature difference between thermal expansion and contraction of the region will not have the stress and damage.
Insulation
Prevent the heat in the aluminum-magnesium manganese metal roof on both sides of transmission of the indoor temperature stability. Insulating function by magnesium manganese metal fill insulation under the roof (commonly used with glass wool, rock wool) to achieve the insulation effect to the U-value, the unit is W/M2K. Insulation by the following factors: cotton insulation materials, density, thickness; insulation cotton humidity, magnesium and manganese metal roof substructure connections (to prevent "cold bridge" phenomenon); magnesium manganese layer of metal roofing repeated heat radiation capability.
Sound-absorbing
Reduce the reflection of sound and reduce echo chamber. Sound-absorbing function of magnesium by manganese in the bottom of the metal roof were laid sound-absorbing cotton and punching on the floor to achieve. Magnesium manganese metal roof of the acoustic properties of the sound absorption coefficient a that.
Moistureproof
Prevent magnesium manganese and magnesium manganese metal roofing metal roofing underlying layer water vapor condensation to drain away the layer of aluminum-magnesium manganese metal roof water vapor. Manganese in the magnesium solution is filled with metal roofing insulation layer cotton, capped with aluminum-magnesium manganese metal roof home floor waterproof membrane, magnesium manganese metal roof can be ventilated on the node.
Fireproof
Magnesium manganese when the fire will not burn metal roofing materials, flame does not penetrate the aluminum-magnesium manganese metal roof.
Ventilation
Indoor and outside air exchange. Manganese in magnesium metal roof vents on the set.
Anti-avalanche
Manganese and magnesium in the snow region setting block snow on metal roof railing, to prevent the sudden snow fall.
Pollution
Magnesium manganese metal roofing material will not cause environmental pollution, 100 per cent recycled materials, recyclable, environmentally friendly.
Light Pollution
Magnesium manganese metal roof surface by coating or hammer handle, the elimination of light pollution generated by surrounding environment.
Normal life
Magnesium manganese metal roof life should be the same with the main building, such as 25 years, 50 years, 100 years.
Maintain
Magnesium manganese metal roofing in the lifetime of easy maintenance, lower maintenance costs.
Cost
Control magnesium manganese metal roof construction costs, the cost of the best metal roofing material.
