Langfang Voda is mainly engaged in hollow aluminum spacer strips, corner sizes of hollow aluminum strips and butyl rubber strips. At present, there are many specifications of hollow aluminum spacer strips in stock, and the 4a-27a hollow aluminum spacer strips have sufficient inventory. At present, most doors and windows in the market use hollow glass aluminum spacer strips. The demand of the door and window market is growing, and the competition is becoming more and more fierce. Most manufacturers have begun to cut corners. A large number of hollow aluminum spacer strips whose production thickness is not up to standard and whose quality inspection is not qualified are trying to make up for the number, impacting the market with price, so that the cost gap between major door and window factories becomes larger. Our company has been strictly controlling the production and quality inspection of hollow aluminum spacer strips. We hope to use the best quality and service to feed back to the major door and window factories that use hollow aluminum spacer strips. Thank you for your support for many years.
