How to deal with common problems in Window and Door Profile

Window and Door Profile is favored by consumers for its beautiful appearance, high strength, anti-aging, good sealing performance, and no maintenance. However, if the selection of profiles is improper, the installation is not standardized, and the quality of accessories is poor, it will affect the appearance and normal use of plastic steel doors and windows. Jinan Lumei Plastic Steel Profiles Company will share with you the more prominent quality problems.

1. Soon after Window and Door Profile is used, water accumulates in the inner slide

The main reason for the accumulation of water in the slide is that the temperature difference between indoor and outdoor is too large in winter. When the warm and humid indoor air encounters the glass, it turns from gas to water and flows into the inner slide, while the middle slide has no drainage measures, resulting in long water accumulation. Time to store.

Window and Door Profile stagnant water causes long-term storage of water not only affects the function of doors and windows, but also causes dirt and other dirt to accumulate in the slide, which affects the appearance of doors and windows.

Solution: In order to prevent water accumulation in the slideway, after cutting the doors and windows, use a profile milling machine to mill both ends of the slideway in the middle of the slideway by 25mm. After welding, the middle slideway will have a drainage groove, which will not affect the doors and windows. The use of the function also solves the problem of water accumulation in the inner slide.

2. The screws in the glideslope of Window and Door Profile are rusted after use

The main reason for the rust of the screw is that the surface of the plastic profile is damaged when the choke block is installed. In rainy weather, rainwater flows from the gap of the screw into the profile cavity to form water, which causes the screw to rust.

This phenomenon not only reduces the strength of the doors and windows, but also shortens the service life of the steel lining; the installer uses a screwdriver or hammer to damage the galvanized layer of the screw, and the screw will rust when wetted by rain.

The solution proposed by Jinan Lumei Plastic Steel Profile Company: In order to prevent the screw from rusting, in order not to damage the surface of the plastic steel profile when installing the wind choke, high-strength double-sided stickers can be used to fix the wind choke, or glass glue can be used to fix the wind choke. , But the bonding time is long and easy to be destroyed.

3. Difficulty in opening and closing of Window and Door Profile and inflexible opening and closing of locks

The main reasons for the difficulty of opening doors and windows and the inflexible opening and closing of locks are the deformation of doors and windows, irregular installation, poor quality of accessory locks, and inaccurate installation.

In the process of making doors and windows, low-strength steel linings are used; the size of the blanking is not accurate; the assembly is not in place, making it difficult to open and close the doors and windows, and the opening and closing of the locks is not flexible. When installing doors and windows, if they are not calibrated horizontally and vertically, side-hung doors and windows are flexible when opened, but relatively difficult to close; while sliding doors and windows, because the upper part of the door and window sashes are against the inner wall of the upper frame groove, friction increases, and it is difficult to push and pull; If the distance is too small, friction will increase and the relative sliding between them will be restricted. When the accessory is installed, if the pulleys in the sliding window are worn, the two pulley axles on the same fan are not parallel, the axles are not perpendicular to the slide rail, the hinge axis of the casement window is not in line, or the hinge is broken, etc., will affect Flexibility of door and window switch. In addition, the inaccurate installation position of the lock and the poor quality of the lock will also affect the opening and closing of doors and windows.

Solution: In order to prevent the difficulty of opening and closing doors and windows and the inflexible opening and closing of locks, the steel lining should not be too thin when selecting materials, and its strength and matching dimensions should meet the corresponding national standards or product technical requirements. It is recommended to use rectangular steel at key nodes Lining; in the purchase of lock accessories, you should choose products with good quality assurance and good reputation; when cutting doors and windows, the dimensions and angles should be sawed accurately, and mass-produced products should be used as much as possible; when assembling doors and windows, pay attention to the assembly in place , The seams are tight and the connection is reliable; when installing doors and windows, two-way hanging is recommended, and attention should be paid to whether the width of the doors and windows is horizontal, and the height of the doors and windows is vertical.

4. Window and Door Profile seepage

There are many reasons for the water seepage of doors and windows. For example, in the design of the profile structure, the height of the lower frame water retaining plate is too low, and the opening size of the bead is too large; when the doors and windows are cut and assembled, the deformation of the doors and windows affects the closing and the sealing strip does not work. The connection gap between the door and window components is too large; the layering or sealant is aging, broken and falling off, the opening size of the glass and the layering, and the size of the layering are not matched, the layering does not have shrinkage margin, and the cross-sectional size and shape of the sealing strip and the layering are unreasonable, sliding under the door and window The frame does not have drainage holes, etc.; when the doors and windows are installed, the width is poor and tilted inward, the gap between the door and window frame and the opening is not well sealed, and no waterproofing is done.
