Villa fell into the water supply of high quality aluminum drainage system: I provide the North American popular 5-inch K type hyperbolic appearance, and European and American popular 6.5-inch semicircle (H) type, and other design, excellent weather resistance and chemical stability, look as new. Safety component, green. A substantial increase in the use of metal pieces by the force of security and reliability, to meet wind and snow load, performance and lasting. And recyclable. High performance, affordable. The water compared with the traditional system products. Luxury noble, natural simplicity, harmony, simple, durable, convenient construction, highlighting the royal demeanor. Easy to cut, easy to install, does not require special tools. Ruichen metal gutter colorful, metallic finish. Rich colors for designers and developers to bring various options. Metallic facade for the building to bring simple visual experience, immediately improve housing quality, highlighting the value of housing, fashion and elegance coexist, is preferably arranged European style architecture. Market center which is a basic principle Ruichen operations. Metal water system is more environmentally friendly. Building Materials Co., Ltd. Hangzhou Ruichen raw water system using high-tech weather formula, superior performance, long life, anti-aging, yellowing, flaking and corrosion phenomenon does not occur even in the rain, salt corrosion and other harsh environments ; the same formula was introduced from North America to the new non-toxic additive, in line with environmental protection requirements. Performance testing impact Cailv the water system Experiment 1: falling height of 15mm diameter from 500mm mass of 500 g of balls coating without peeling 2: Bending test at room temperature 180 degree bend test without coating by a hand press peeling, no cracks substrate 3: salt corrosion test were cross-cut with a cutter to just touch the aluminum plate so far, under the conditions of 35 degrees, 5% saline solution injector 360 hours. Corrosion rust from the incision spread of no more than 2mm acid etch test 10% HCL, CHCOOH, H2SO4 experiment 100 hours. No surface change 4: Greenhouse experiments minus 50 degrees in the north and tropical heat prolonged sun exposure, use of stable performance under conditions of 60 degrees, such as a color. Alternative metal fell into the water system? downspouts part of a partial cement replacement b PVC gutter fell into the mouth of the water system to replace replace replace c PVC water pipe installation d Cailv comprehensive installation, color steel, copper fell into the water system.
