View: 0 Point
At present, rolling shutter doors are widely used in residential garages, shops along the street, industrial workshops and other scenes. Steel profiles were once the mainstream material selection, but long-term use exposed rust, cumbersome maintenance and other short boards. 6063-T5 aluminum roller shutter profile relies on aluminum alloy material characteristics and mature deep processing technology, all-round rolling steel profiles, becoming the first choice for engineering procurement at home and abroad.
Better Corrosion Resistance for Long-Term Outdoor Use
Outdoor Metal Corrosion Hazard
Building roller shutter profiles are placed in the open air all year round, and continue to withstand rain erosion, temperature difference between day and night, ultraviolet radiation, salt fog in coastal areas, acid rain dust in the factory area will continue to erode metal substrates. The steel itself does not have natural oxidation resistance, and the matrix directly contacts water vapor, which will produce red rust and pitting in a short time. Metal corrosion not only destroys the surface appearance, rust will continue to expand inward, continuously weaken the thickness of the profile section and the overall structural strength, roller shutter guide rail, bottom beam corrosion deformation will appear stuck, stuck shell. Frequent maintenance and replacement will continue to increase the capital investment in the later stages of the project and will not meet the design standards for long-term use of buildings for 20 to 50 years.
6063 series aluminum alloy contact with the air, the surface will spontaneously generate a layer of nano-level dense alumina film, film damage can quickly re-combine with oxygen molecules in the air to complete self-repair, from the root block electrochemical corrosion reaction, the basic corrosion resistance is far better than unprotected steel. For strong corrosive environments such as seashore and chemical plants, manufacturers can stack anodic oxidation, electrostatic powder spraying, PVDF fluorocarbon three-layer protection process, multi-layer protective film firmly isolated from salt fog, acid and alkali pollutants, and outdoor use for decades will not appear rust spots and white spots, greatly extending the overall service life of the roller shutter system.
Lightweight Design Reduces Installation and Operation Costs
Aluminum Lightweight Material Principle
The density of aluminum is only 2.70g/cm³, and the overall weight is only one third of that of steel. After T5 air-cooling aging treatment, 6063-T5 retains sufficient structural rigidity while greatly reducing weight, and will not bend or collapse due to lightweight. Steel roller shutter weight is huge, the same size weight is more than three times aluminum profile, to the building wall, embedded parts bring huge load-bearing pressure. Lightweight design can optimize the cross-section shape of profiles and make slender and exquisite roller shutter blades and guide rails, taking into account both aesthetic and load-bearing standards. It is not like steel that can only rely on thickened plates to increase strength. The heavy and heavy structure seriously limits the facade design of buildings. effect.
Full Chain Lightweight Cost Reduction
In the logistics transportation link, under the same truck load limit, the loading capacity of aluminum profiles is much higher than that of steel, which effectively reduces the number of transportation trains, reduces fuel consumption and logistics freight, further widens the cost gap when large-scale batch procurement, and at the same time reduces the carbon emission of transportation, so as to meet the low-carbon requirements of green buildings. The construction site does not need to rent large-scale lifting equipment, two to three workers can complete the handling, splicing and fixing of profiles, the installation speed is 20%-40% higher than that of steel roller shutters, the overall construction cycle is shortened, and the extra expenses such as labor, scaffolding and crane rental are reduced. After being put into use, the roller shutter motor and spring load are smaller, the wear speed is slowed down, and the replacement cycle of accessories is greatly extended.
Higher Strength-to-Weight Ratio Ensures Reliable Performance
Strength to Weight Ratio Core Criteria
Strength to weight ratio represents the load value that the unit weight material can bear. 6063-T5 aluminum alloy relies on magnesium silicon alloy ratio, precision extrusion molding and T5 heat treatment triple process. Under the premise of lightweight, tensile strength and bending resistance are completely comparable to or even superior to ordinary carbon steel. Although the absolute strength value of steel is higher, its heavy weight reduces the effective bearing efficiency. In order to achieve the same wind pressure resistance and snow resistance standards, steel needs to be thickened greatly, and the overall weight increases exponentially, which increases the bearing burden of building foundation and wall and increases civil construction cost.
High Strength to Weight Ratio Adapts to Complex Working Conditions
High-rise shops and coastal buildings need to withstand strong wind pressure, the rolling shutter in the northern factory area has to withstand the heavy snow pressure in winter, the earthquake-prone area has strict requirements on the seismic toughness of the profile, and the 6063-T5 aluminum profile has excellent toughness, which can buffer the impact of external forces and is not easy to permanently deform and crack. Aluminum alloy thermal expansion coefficient is lower, the deformation amplitude of profiles is very small under the alternating temperature difference of four seasons, the gap between roller shutters will not be excessively offset, and the guide rails and blades will not be loosened and misplaced for a long time. With anti-corrosion coating, decades of use of mechanical performance attenuation is very low, always maintain stable opening and closing effect.
Better Appearance with Multiple Surface Treatment Options
Diversified Surface Technology Adaptation Design
6063-T5 aluminum substrate is suitable for a complete set of mature surface treatment processes, anodizing can make matte silver, champagne, bronze, black metal texture; polyester powder coating has thousands of RAL standard colors and custom spot colors;PVDF fluorocarbon coating for high-end facades; wood grain transfer can be engraved with wood grain. 6064-Steel profiles can only be galvanized, ordinary outdoor painting two treatment methods, color selection is very few, paint adhesion is poor, slight bump will fall off the whole, late paint color difference is obvious, it is difficult to match the diversified facade design requirements of modern buildings.
Anti-aging Long-term Aesthetic Performance
Anodic oxidation, fluorocarbon spray coating dense anti-ultraviolet, perennial exposure will not appear fading, powdering, loss of light problems, rain washing can remove surface dust, cleaning difficulty is extremely low, many years after the whole building roller shutter color is still uniform. Wood grain transfer aluminum roller shutter has the advantages of solid wood appearance and metal fire prevention and corrosion prevention. It is perfectly suitable for villas and light luxury commercial street projects. It will not mold, peel and discolor like solid wood and painted steel. After one-time molding treatment, it does not need regular renovation and paint repair. It maintains the overall aesthetics of the building for a long time.
Excellent Weather Resistance for Different Climates
Multi-climatic Environment Test
Climate environment varies greatly in different regions of the world: high salt fog and high humidity in coastal areas all the year round; continuous high temperature and rainstorm in tropical Southeast Asia; temperature difference between day and night in northwest desert exceeds 30℃, sand sand and sand continue to polish; repeated freezing and thawing in winter in north China, acid rain areas exist acidic corrosive medium all the year round. Ordinary steel in any kind of extreme environment for a long time will be rapid aging rust, thickened galvanized layer can only delay corrosion in a short period of time, rust will appear in 2-3 years, can not adapt to cross-regional, long-term outdoor engineering uniform material selection standards.
6063-T5 Profile Full Climate Stability
Relying on the double protection of alumina self-protective film and composite coating, 6063-T5 aluminum profile can maintain structural integrity under salt spray, high temperature, cold and sand environment, freeze-thaw cycle will not cause coating cracking and peeling, and sand friction is not easy to scratch the surface protective layer. After AAMA, ASTM international weathering standard accelerated aging test, high-quality spray aluminum profiles outdoor stable use of 30 to 50 years without obvious loss, whether it is Southeast Asian coastal shops, Middle East desert factory or Nordic low temperature warehouse, can maintain the complete function of the roller shutter, versatility far more than steel profiles.
Pure metal heat conduction speed is fast, ordinary steel roller shutter has no heat insulation design, outdoor heat is quickly transmitted into the room in summer, indoor heating is lost outward in winter, greatly increasing the energy consumption of air conditioning and heating equipment, and it is easy to generate condensed water droplets on the inner wall of the profile, breeding mold spots and corroding the wall. 6063-T5 aluminum profiles can be reserved in the extrusion stage of insulation strip card slot, assembly PA66 nylon insulation strip to create a broken bridge structure, with multiple hollow cavity design to trap static air, cut off cold heat conduction path, effectively reduce the profile heat transfer coefficient, achieve excellent thermal insulation effect.
Energy Saving Profiles Reduce Building Energy Consumption
The aluminum roller shutter can block the exchange of cold and heat, the load of building HVAC equipment is reduced by 20%-40%, the annual electricity and gas heating expenses of shops and factories are significantly reduced, and the energy cost saved for long-term use is considerable. Energy-saving aluminum profiles can help projects apply for LEED, BREEAM, and domestic green building three-star certification, meeting the current low-carbon building and near-zero energy consumption building policy requirements. Developers and property owners can enjoy green building related policy support, which has both environmental protection value and economic benefits.
Easier Customization Through Aluminum Extrusion Technology
Aluminum Extrusion Molding Advantages
After heating, the aluminum rod is extruded by a customized mold under high pressure, and a complex integrated section with a guide groove, a sealing clamping groove, a screw installation position and a heat insulation cavity can be made in one molding, and the molding size tolerance is precise, so that a large number of secondary cutting and welding processes are not needed. The complex section of steel can only be produced by bending and welding of steel plates. The weld position is easy to rust and deform. The processing procedure is complicated. The cost of customized mold opening is high. The production cycle is long. It is difficult to land small batch personalized orders, which limits the design creativity.
Custom Profiles Adapt to Various Projects
Designers can customize the thickness, guide rail width, surface texture and sealing structure of rolling shutter blades according to project positioning. Villas can be made into slim and silent models. Factory buildings can be thickened to improve impact resistance and anti-theft performance. Shops can be equipped with curved and special-shaped rolling shutter shapes. Integrated extrusion molding reduces parts splicing, reduces installation gaps, improves dust prevention, waterproof and sound insulation effects of roller shutters, has a short development cycle, can undertake large and small orders, and takes into account individual design requirements and batch supply efficiency. It is suitable for various commercial, residential and industrial projects.
Lower Maintenance Requirements Compared with Steel Profiles
Steel Roller Shutter Operation Pain Points
Steel corrosion depends on surface coating, corrosion will spread rapidly after coating damage, outdoor scenes need to be regularly derusted, polished and repainted every year, and high labor and equipment costs will be incurred when erecting scaffolding for high-altitude shops. Coastal and chemical plants corrode faster, and they need to be fully repaired and renovated every 1-2 years. Rust accumulation will also jam roller shutter blades and damage spring motors. Frequent failures will cause shops and factories to fail to operate normally, indirectly causing business losses.
6064-T5 Aluminum Low Operation and Maintenance Advantages
