How to buy1. If you choose a wooden door:When using a wooden door as a bathroom door, please note that PVC membrane doors that are not painted on the surface cannot be used in the bathroom, because the waterproofness of the membrane is not as good as the paint, and the moisture entering the substrate will easily cause blistering and deformation. The problem with the door is not the problem in the center of the door, but the door cover and frame, which has nothing to do with the middle. Therefore, the door cover of the bathroom door needs to be replaced with wood-plastic door cover line or solid wood door cover line. It is best to implement it when ordering the wooden door of the bathroom.Under normal circumstances, the paint effect of slightly better wooden materials is still very good, coupled with better processing, can improve the waterproof performance and deformation resistance of wooden doors.2. If you choose steel-plastic doors:The profile of the steel-plastic door needs to be lined with a galvanized cold-rolled steel that has been cut, welded, and installed. If there is no galvanized cold-rolled steel in the door, this is not the first choice for bathroom doors.3. If you choose aluminum alloy door:When we buy aluminum alloy doors, we should pay attention to whether the joints of each part of the door have fine workmanship. You can also choose the appearance of the door appropriately. At present, many brands of aluminum alloy doors and titanium-magnesium alloy doors have mature technology, and the color and texture of the doors can match the brand wooden door manufacturers. With its excellent waterproof, moisture-proof and anti-deformation performance, coupled with a good appearance, and super high cost performance, it has become the first choice for many families.This is the end of the purchase of bathroom doors. When choosing a bathroom sliding door or a swing door, you should not only pay attention to the quality, but also match the style of your own home.
