Installation and maintenance specifications
Installation requirements
1. Before installation, it is necessary to check the size of the opening and the specifications of the door body to ensure that the verticality and flatness deviation of the opening is ≤ 5mm, and the reserved installation gap is 25-30mm; the foundation needs to be reinforced with concrete (thickness ≥ 150mm) to ensure the bearing capacity of the door body and avoid settlement deformation.
2. Door frame fixation uses expansion bolts or pre-buried iron pieces, spacing ≤ 500mm, firmly connected to the foundation/wall; the gap between the door frame and the wall/ground is filled with polyurethane foam, and the outside is applied with weatherproof sealant to ensure sealing and waterproofing, preventing water penetration.
3. The installation position of hardware components is accurate, fixed firmly, the hinges/sliders need to be adjusted to be flexible and smooth in rotation; the lock system needs to be repeatedly tested to ensure tight locking and convenient unlocking; for electric models, the power connection needs to be correct, the motor operation and remote control function need to be debugged to ensure coordinated movement.
4. After installation, opening and closing tests, water spraying tests and anti-theft tests need to be conducted, checking for no jamming, leakage, abnormal noise, and normal lock function before acceptance.
Daily maintenance
1. Avoid sharp objects from hitting or scratching the profiles and glass (or grilles). Do not drill or cut holes on the door body to prevent damage to the structure and anti-corrosion coating.
2. Clean the surface of the door body regularly (every six months). Use a damp cloth to wipe the profiles, glass and tracks. Do not use strong acid or alkali cleaners. If there are any debris (such as stones or fallen leaves) inside the tracks, remove them promptly to ensure smooth sliding.
3. Regularly (once a year) add lubricating oil to the hardware components (it is recommended to use silicone oil or lithium-based lubricating grease) to keep the opening flexible. The lock core can be regularly coated with graphite powder to improve the smoothness of unlocking. If the sealing rubber strips become aged or cracked, replace them in time.
4. For electric models, regularly check the motor, wiring and remote control device to keep them dry and clean. Avoid moisture-induced short circuits. Open and close the door several times each month to ensure the motor operates normally. When not in use for a long time, it is recommended to disconnect the power supply and take protective measures.
5. After winter snow and ice weather, promptly remove the snow and ice from the door body and tracks to prevent ice formation from affecting the opening. Avoid hitting the ice layer with hard objects to prevent damage to the door body and glass.

FAQ：
1. Which is more durable, the aluminum patio door or the iron-wrought patio door?
The aluminum patio door is more durable. The aluminum profiles are treated with anti-corrosion coating, which is resistant to outdoor wind, rain, humidity, and ultraviolet rays. It won't rust or fade, and can last for over 25 years. The iron-wrought door is prone to rust and corrosion, and requires regular painting maintenance. Its lifespan is shorter, and it is heavy, so it is prone to door frame deformation over time.
2. Which opening methods are suitable for aluminum patio doors? How to choose for different house types?
The mainstream opening methods include sliding, push-pull, and folding. For small-sized courtyard entrances (width ≤ 3m), choose the sliding type, which is convenient to operate and doesn't occupy space; for medium-sized entrances (3m - 6m), choose the push-pull type, suitable for scenarios with no extra space on both sides; for super-wide entrances (6m - 8m), choose the folding type, which can maximize the passage width and is suitable for villas and manors, etc., large house types.
3. How is the anti-theft performance of the aluminum patio door? How to enhance the anti-theft level?
Qualified products have excellent anti-theft performance. The standard configuration includes thickened profiles + multi-point linkage C-level anti-theft lock + laminated tempered glass (or solid grille). The anti-picking time is ≥ 15 minutes. To enhance the anti-theft level, you can add smart locks (Fingerprint / Password /remote unlocking)， anti-picking alarm devices， and for grille models， you can reduce the grille spacing (≤ 80mm) to prevent climbing.
4. Will the aluminum patio door fade or deform in outdoor use?
The surface of high-quality aluminum patio doors is treated with powder coating or fluorocarbon coating， which has strong weather resistance. Under normal outdoor use for 10 - 15 years， there will be no significant fading. The profile wall thickness is ≥ 2.0mm and has an enhanced reinforcement design， making it strong against wind and pressure. As long as it is installed firmly， it won't deform due to temperature differences or external forces.
5. Are the hardware components of the aluminum patio door prone to failure？ What should be noted when using outdoors?
Choose 304/316 stainless steel heavy-duty hardware components. The salt spray test is ≥ 72 hours， which is corrosion-resistant and has strong load-bearing capacity. Under normal use， the lifespan can reach 10 - 15 years. When using outdoors， it is necessary to regularly (once a year) add lubricating oil to the hinges and pulleys to prevent sand and debris from entering the track； the lock core should be regularly coated with graphite powder to keep the unlocking smooth.
6. Can the aluminum patio door be customized with patterns， colors， and sizes?
Yes， it can be customized. It supports powder coating (conventional black， gray， brown)， fluorocarbon coating (custom colors)， wood grain transfer (imitating redwood， teak)， etc. as surface processes； patterns can be customized as Chinese-style carvings， European-style hollowing， modern minimalist grilles， etc.； the size can be non-standardly customized according to the width and height of the courtyard entrance， and the maximum can be an 8m-wide folding door.
7. How is the sealing effect of the aluminum patio door？ Will it leak air or rain?
It uses EPDM (triple rubber) weather-resistant sealing strips， combined with adjustable bottom sealing strips. The sealing effect is good， and under normal use， it won't leak air or rain. If there is leakage， it is mostly due to aging of the sealing strips or cracking of the sealing rubber during installation. Replacing the rubber strips and applying weather-resistant glue can solve the problem.
8. Can the aluminum patio door be equipped with smart devices？ What are the common smart configurations?
Yes， it can be equipped. Common smart configurations include smart locks (Fingerprint / Password /APP remote control)， wind and rain sensor automatic opening， anti-picking alarm system， door access camera， etc. Some electric models can also be linked with smart home devices to achieve scene linkage such as automatic lighting when opening the door and closing the window.
9. What should be noted during daily maintenance of the aluminum patio door？ How often should it be maintained?
Just wipe the surface of the door body with a damp cloth. Avoid using strong acid and strong alkali cleaning agents. Clean the track debris (stones， fallen leaves， etc.) once every six months. Add lubricating oil to the hardware components once a year and check if the sealing strips are aging. Electric models should be opened once a month to avoid the motor getting damp due to long-term idleness.
10. Is it suitable to install aluminum patio doors in coastal areas？ What special treatments are needed?
It is very suitable. The coastal areas have high humidity and heavy salt content. The corrosion resistance of aluminum alloy is much better than that of iron. Special treatment options include fluorocarbon spraying technology (which offers stronger salt spray resistance), 316 stainless steel hardware accessories. During installation, weather-resistant sealant should be used to fill the gap between the door frame and the wall. Regularly rinse the surface of the door with clean water to remove salt and prevent corrosion.
