Dajian Industry Co., Ltd. is one of Japan's top comprehensive building materials brands, and is also a first-class comprehensive manufacturer of building materials in the international industry, with a perennial market share in the wood products industry ranking among the top three in Japan, and its products cover many fields such as solid wood composite doors and solid wood flooring. Like LIXIL, Dajian wooden interior doors follow the F4 Star certification, the highest level of environmental protection in Japan's building materials category, and have excellent environmental performance. There are a wide variety of styles and designs of doors, which are suitable for various life scenarios. The Lihao series belongs to a simple and modern style, and the wood grain decoration on the surface is harmonious and beautiful; The classic series is more calm and luxurious, with a slightly retro style; In addition to the modern style, the wooden doors of the RM series are decorated with delicate reliefs, and the overall sense is more high-end. In addition to the general set door, Dajian also has a "pet door", which is set up with a small passage under the door, which is convenient for the little ones to enter and exit freely. The large indoor wooden door is made of hardware imported from Japan, which has good anti-corrosion and is not easy to fade, and the surface has been treated with antibacterial treatment, which is very durable. It is a pity that the current sales channels of Dajian in China are not perfect enough.
