How to choose aluminum alloy doors and windows? Just these few steps to choose high-quality aluminum alloy doors and windows

1 Features of aluminum alloy doors and windows: Most of the high-end aluminum alloy doors and windows are simple, fashionable and high-end, which are more suitable for the new rich in the city. and white-collar workers, customized high-end aluminum alloy doors and windows are also suitable for the decoration of villas and large apartments. If you require quality, texture, and class, then of course you choose aluminum alloy doors and windows. The new broken-bridge aluminum alloy doors and windows have better overall decoration effects and various performances.

Lightweight and resistant to bending

Since the sections of door and window frames are mostly hollow thin-walled composite sections, this section is easy to use and is durable due to fastening. The mass of aluminum alloy profiles is reduced, and aluminum alloy doors and windows are about 50% lighter than steel doors and windows. When the cross-section size is large and the mass is light, the cross-section has high bending stiffness.

Good airtightness

Tightening performance is an important performance indicator of doors and windows. Compared with ordinary wooden doors and windows and steel doors and windows, aluminum alloy doors and windows have better air tightness and Excellent water tightness and sound insulation performance. Aluminum alloy doors and windows themselves are slightly less airtight than flat doors and windows. Therefore, nylon tops are added to the structure of sliding doors and windows to enhance their airtight performance.

The degree of deformation is small

Firstly, it is because of the good stiffness of the profile itself, and secondly, because of the cold connection used in its production process. Screws, bolts or aluminum nails are used to install the horizontal and vertical rods and hardware accessories. It uses angle aluminum or other types of connectors to connect the frame and fan rods into a whole. Compared with the electric welding connection of steel doors and windows, this cold connection can avoid deformation caused by uneven heating during the welding process, thereby ensuring manufacturing accuracy.

Facade decoration

Firstly, the appearance is beautiful and the doors and windows are large, which makes the facade of the building simple and bright, and increases the contrast between virtual and real, rich in layers. Second, the color is beautiful. The door and window frame materials have been oxidized and colored, and can have silvery white, golden yellow, bronze, bronze and other tones or colored patterns. The appearance is gorgeous and elegant, and there is no need to paint or perform surface repairs.

Aluminum alloy doorClassification

According to the type of outer door frame: ordinary single outer frame aluminum door, single outer wall aluminum door, full frame wall sealed aluminum door.

According to the door opening method: push-pull aluminum alloy door, swing aluminum alloy door, folding aluminum alloy door.

Hinged door

It refers to a door whose door leaf is centered on the vertical mullion and opens horizontally. Swing doors are the most commonly used type of door. According to the different opening directions, it can be divided into two types: inward opening and outward opening. The opening direction of the swing door is mainly determined by its function and the need to occupy as little indoor space as possible after opening. In general, interior doors of buildings often open inwards, while exterior doors and emergency doors of buildings often open outwards.

Sliding door

refers to a door that can be opened and closed by pushing and pulling left and right along the width direction. Common sliding doors have two forms: exposed and concealed. Exposed sliding doors refer to sliding doors and tracks that are outside the wall, while concealed sliding doors refer to sliding doors with door leaves and tracks in the middle of the wall. Sliding doors take up little space during opening and closing, so sliding doors can make full use of indoor space.

Folding door

Folding door refers to a door whose leaves can be folded during opening. It can be divided into two basic types: flat folding doors and sliding folding doors. Since the folding door can be folded when it is opened, it takes up less space and can often be used as an effective method to re-separate and combine indoor spaces – living partitions. The flat folding door is mostly used in small toilets or washrooms. .

Aluminum alloy door VS plastic steel door VS wooden door

Door material comparison advantages and disadvantages Aluminum alloy doors are highly waterproof, have many styles, rich colors, and are resistant to deformation The ability is relatively strong. It is also cheap, anti-fouling, moisture-proof, and rust-resistant. Because the materials of aluminum alloy doors are different, the texture is different from that of bedroom doors, the quality is not stable enough, and the appearance and quality are average. Plastic steel doors are highly waterproof and cheap, ranging from tens to two hundred yuan.have. It is not very beautiful. The visual effect of the plastic steel door is relatively low. Many small restaurants use this kind of door, and it is easy to change color and deformation. Wooden Doors The biggest advantage of wooden doors is that they have the same texture as bedroom doors, are of high grade, and are the strongest from an aesthetic point of view. The waterproofness and deformation resistance are not as good as those of aluminum alloy doors, and the cost is high, but the waterproofness of solid wood doors is still relatively strong. 4 How to choose aluminum alloy doors

Check the thickness

Aluminum alloy interior doors, profiles are 0.8 mm, 1.0mm, 1.2mm and other thicknesses. Among them, aluminum alloy doors with a thickness of more than 1.0 mm have better strength and will not deform for 5 to 8 years under normal use. The thickness of the profile directly determines the quality of the aluminum alloy door. When consumers purchase aluminum alloy doors, they should not be greedy for cheap and choose aluminum alloy doors with too thin profiles.

Look at the seal

Choose aluminum alloy doors with inlaid glass, especially those designed with insulating glass product, be sure to pay attention to its sealing performance. Check the sealing of the glass partition of the aluminum alloy door. In addition to checking whether the glass glue coating on the front is tight, you should also check whether the sealing strip on the back glass of the door is flat and there is no curling or detachment.

Comparison of process

Special attention should be paid to checking for welding defects, such as open welding and missing welding. It also depends on whether the door leaf and door frame are tightly closed, whether the gap is uniform, and whether the opening is flexible. After consumers check the welding process of aluminum alloy doors, they should also carefully check whether the paint surface of the product is bright in color and clear in texture. Pay attention to the fact that the paint surface should not have obvious scratches, bubbles and other defects.

Choose accessories

Aluminum alloy doors are usually installed in humid environments such as bathrooms and kitchens, so the hardware The quality of hinges, door handles and other accessories is the key to ensuring the service life of aluminum alloy doors. When purchasing aluminum alloy doors, in addition to checking whether the hinges are made of materials that are not prone to rust, it is also best to choose stainless steel door locks, handles and other hardware to prevent rust and affect use.

Aluminum alloy windows vs plastic steel windows

Window material comparison Aluminum alloy windows Plastic steel windows sound insulation without this indicator is far better than aluminum alloy windows strength windshield The main material of Rain Hao is still plastic, but its strength is not as good as that of aluminum alloy, and its sealing ability is not enough to prevent water seepage. Good plastic-steel windows are better at preventing water seepage than aluminum alloy windows. The large area of ​​the window is still glass. The difference is only in the frame. The contrast is not obvious in terms of heat insulation. Broken bridge aluminum insulation is also good. The plastic heat insulation of plastic-steel windows is better than that of metal. Corrosion Aluminum alloy is not easy to age, but it will also corrode and oxidize, affecting the appearance. Plastic steel is more likely to age.If the corrosion is severe, the lifespan will be exhausted, and the lifespan is shorter than that of aluminum alloy

How to choose aluminum alloy windows

Look at the material

Aluminum profiles, glass, hardware, high-quality aluminum Aluminum profile walls used for alloy windows The thickness should be no less than 1.2mm, titanium-magnesium-aluminum alloy is better, and the oxide film thickness should reach 10 microns; tempered glass is better than ordinary glass; stainless steel hardware accessories (such as screws, hinges, handles, etc.) Better than aluminum fittings.

Look at the processing

High-quality aluminum alloy windows, fine processing, smooth tangents and consistent angles (main frame The material is usually 45 degrees or 90 degrees), there should be no obvious gaps during the splicing process, the sealing performance is good, and the opening and closing are smooth. If the processing of aluminum alloy outdoor window products is not up to standard, there will be problems with the sealing properties. Not only will it leak air and rain, but the glass will also burst and fall off under the action of strong winds and large external forces.

Look at the appearance

The surface of the aluminum alloy window should not have obvious scratches, scratches, bumps, etc. defect. There should be no obvious color difference between the colored surfaces of adjacent components on the window. There should be no aluminum chips, burrs, oil spots or other stains on the window surface, and there should be no spilled adhesive at the assembly joints.

Look at the performance

Strength is reflected in the selection of aluminum alloy window profiles, whether it can withstand Ultra-high pressure; air tightness, mainly reflected in the window structure, the inner sash of the window Whether it is tight with the outer frame structure, etc.; water tightness, which mainly assesses whether there is water accumulation or leakage in the aluminum alloy window; sound insulation, which mainly depends on the sound insulation effect of the insulating glass and other special sound insulation airtight strip structures, as well as the opening and closing force, Durability of opening and closing locks and other window accessories.

Compare prices

Generally, the price of high-quality aluminum alloy windows is higher than that of inferior aluminum alloy window products. 30% higher, inferior aluminum alloy windows are usually made of recycled aluminum extruded aluminum that contains a lot of impurities Material, some of the aluminum profiles used have a wall thickness of only 0.6-0.8 mm, and both the tensile strength and yield strength are much lower than the relevant national regulations. This type of aluminum alloy windows, especially aluminum alloy outdoor windows, are very unsafe, so When purchasing, do not underestimate the personal safety of yourself and others for temporary convenience.

Material index of aluminum alloy doors and windows

Thickness: The series number indicates the door frame Thickness construction dimension in millimeters. There are two types of aluminum alloy sliding doors, 70 series and 90 series. For residential interior aluminum alloy sliding doors, 70 series can be used. Aluminum alloy sliding windows have 55 series, 60 series, 70 series and 90 series should be determined according to the size of the window opening and the local wind pressure value. Aluminum alloy sliding windows used for enclosed balconies should be no smaller than 70 series.

Strength: The tensile strength should reach 157 Newtons per square millimeter and the yield strength should reach 108 Newtons per square millimeter. Use your hands to bend the profile appropriately, and it should return to its original shape after you let go.

Color: The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not suitable to purchase.

Glossiness: Aluminum alloy doors and windows should avoid purchasing those with open bubbles (white spots) and ash (black spots) on the surface, as well as obvious defects such as cracks, burrs, and peeling. Profiles.

Flatness: Check the surface of the aluminum alloy profile. There should be no dents or bulges.

Oxidation degree: The thickness of the oxide film should reach 10 microns. When purchasing, you can lightly scratch the surface of the profile to see if the oxide film on the surface can be wiped off.

Misunderstandings in purchasing aluminum alloy doors and windows

Emphasis on beauty

Only value the variety of colors and not the inner qualities quality. The double-layer insulated glass and triple-layer laminated glass used are much better than ordinary glass. The thickness of the oxide film should reach 10 microns. You can lightly scratch the surface of the glass profile to see if the oxide film on the surface can be wiped off. If it can be wiped off, it is good.

Heavy thickness

Just choose those that meet the relevant national regulations. The wall thickness of aluminum profiles for doors and windows It should be no less than 1.2 mm. The thickness of aluminum alloy door and window profiles ranges from 0.8 mm to 1.2 mm, and some are even above 1.2 mm. Among them, aluminum alloy doors with a thickness of more than 1.2 mm have better strength and will not deform for 5-8 years under normal use. In addition, thin-walledToo thick is a waste of resources and the price will be much higher.

Light hardware

Hardware accessories are not supporting roles, but the heart of doors and windows. Among the materials for aluminum alloy door and window accessories, it is recommended to use die-cast zinc alloy for handles, transmission parts, etc.; aluminum alloy for hinges, etc.; stainless steel for hinge shafts, locking points, etc., and zinc alloy or stainless steel for lock seats; and pulleys. The quality is determined by the quality of its outer wheel and bearings. The fiberglass pulley contains roller bearings, which are smooth in pushing and pulling, and are wear-resistant and durable. The box-type closed structure is effectively dust-proof, and the two anti-jump devices ensure safety and reliability when sliding.

Light mark

Generally regular manufacturers have production licenses, and the products are clearly Each part will have a mark indicating the product, such as the factory name, \”QS\” logo, product name and date of manufacture, etc. When purchasing doors and windows, you must first pay attention to logo recognition, and you can also ask the shopping guide to show the brand\’s production license and some certificates obtained.

Maintenance of aluminum alloy doors and windows

Push and pull naturally

Aluminum alloy doors and windows in use , the movements should be gentle, push and pull let nature take its course; if you find any difficulty, do not push or push hard, you should troubleshoot first.

Remove dust accumulation

Dust accumulation and deformation are the main reasons why it is difficult to introduce new aluminum alloy doors and windows. Keep door frames clean, especially sliding grooves. Use a vacuum cleaner to remove dust accumulated in the groove and on the door seal strips. When cleaning aluminum alloy doors and windows, people should not step on the aluminum frame or pull on the frame for support.

Remove standing water

Dry wet glass and door and window frames promptly after rainy days, paying special attention to drying Water accumulates in chute. If the chute is used for a long time, the friction will increase. You can add a little engine oil or apply a layer of fire wax oil.

Cleaning method

Aluminum alloy doors and windows can be cleaned with a soft cloth dipped in water or neutral detergent. Do not use ordinary Soap and washing powder, not to mention strong acidic detergents such as scouring powder and toilet detergent.

Repair and Replacement

Check the connection parts of the aluminum alloy frame frequently, tighten the bolts in time, and replace the Damaged parts. The vulnerable parts of aluminum alloy doors and windows such as positioning pins, wind braces, and floor springs must be inspected frequently and lubricated regularly to keep them clean and flexible. Sealing tops and glass seals are key structures to ensure the sealing and insulation of doors and windows. If they fall off, they must be repaired and replaced in time.

Regular inspection

Check the joints between the aluminum alloy frame and the wall frequently. If there is any looseness over time, it will easily deform the entire frame, making it impossible to close or seal the doors and windows. Therefore, loose screws at the connection should be tightened immediately. If the screw footing is loose, use epoxy strong glue mixed with a small amount of cement to seal it.
