Installation material selection for doors and windows
Doors and windows are an indispensable part of the room. So far, doors and windows have gone through four eras: wood, steel, aluminum alloy, and plastic steel doors and windows. Wooden doors and windows are moderately priced, have poor appearance, poor sealing, are afraid of fire and flammable, deform and crack, and are only suitable for low-grade and general places. They have high maintenance costs and short service life.
