Bearing to withstand construction loads, rain, dust, snow pressure, maintenance load. Performance and load-bearing metal roof plate section properties, the strength of the material thickness, the force transmission means, purlins (Vice purlin) spacing on. Maximum wind pressure resistance of local wind pressure, the metal roof will not be pulled off the negative air pressure. Wind resistance and the metal roof and the bracket buckle together, the bracket density. Prevent the spread of noise from the outdoor sound indoors or outdoors from the interior spread. Fill in the layer of metal roofing insulation materials (usually cotton as insulation), the effect of metal roofing insulation layer 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. Impermeable to prevent rainwater infiltration from the outside to inside the metal roof. Rain water mainly through the gap or overlap the node into the metal roof. 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 the lead to ground lightning, thunder and lightning to prevent the breakdown of metal roof into the interior. Lighting during the day to improve indoor lighting through skylights to save energy. A specific location in the metal roofing panels or lighting glass lighting arrangement should be considered the life of the metal roof skylights, in coordination with the metal roof skylights connection waterproofing treatment. Safety devices on the metal roof with fixed facilities, to protect construction workers and maintenance personnel. Prevent icicles forming at the eaves to prevent icicles in the rain and snow. Aesthetic appearance of metal roofing has a good texture, pleasing color. Control thermal expansion and contraction control of the contraction of the metal roof displacement and direction. Ensure that the temperature difference between the metal roof in the area will not produce thermal expansion and contraction of stress and damage. Insulation to prevent heat transfer on both sides of the metal roof, indoor temperatures stable. Function through the roof insulation under the metal fill insulation materials (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, and lower metal roof structure connection (to prevent "cold bridge" phenomenon); metal roofing layer capabilities of the repeated thermal radiation. Reduce the reflection of sound-absorbing sound, reducing indoor echo. Sound-absorbing function by the underlying metal roof were laid in the sound-absorbing cotton and punching on the floor to achieve. The acoustic properties of the metal roof to a sound absorption coefficient, said. Moisture to prevent the bottom of the metal roofing and metal roofing layer water vapor condensation to drain away the water vapor layer of metal roofing. The solution is filled in the metal layer of roof insulation cotton, capped with metal roof home floor waterproof membrane, metal roof can be ventilated on the node. Fire when the fire will not burn the metal roofing material, the flame will not penetrate the metal roof. Ventilation for indoor and outdoor air exchange. Set on the metal roof vents. Anti-snow avalanche in the area of ​​the metal roof railings set on the snow block to prevent the sudden snow fall.
