The first impression of a linear drainage system is that a straight line is clean and tidy. In fact, it is basically the same. Linear drainage originated in the European market. Linear drainage is a modular system composed of various components, and the combination of modules of various specifications can satisfy each To meet the needs of customers, its unique and individual design concept also creates more imagination and development space for designers, becoming a more reliable product in the field of modern construction. The material of the drainage channel is resin concrete, which is a new type of building material. The ingredients are taken from natural minerals, such as quartz sand crystals, sandstone foam, granite, etc. as aggregates, which are screened according to particle size and proportioned and combined with synthetic resins to generate resin concrete with good characteristics. Resin concrete has : High strength, light weight, anti-aging, anti-freezing, smooth molding surface, strong corrosion resistance, no penetration and other advantages, its strength and life are significantly higher than the performance of ordinary concrete, it is a new milestone in modern building drainage system.
