Color plate coating is a cold-rolled steel, galvanized steel, chemical surface treatment after coating (roller coating) or composite organic film (PVC film), and then cured by baking and made products. Some people call this product as "pre-roll coating color steel", "plastic color plate." Color board products manufacturer in continuous production line into volume production, it is also known as color coated steel plate. Choi plate steel material with both high mechanical strength, easy molding performance, but also both good decorative coatings and corrosion resistance. Color plate is the world's respected emerging materials. With advances in technology, environmental awareness, improve people's living standards, Choi activities of the steel has increasingly shown strong vitality and broad market prospects, by construction, household appliances, machinery, transportation, interior, office furniture and other industries of all ages. Choi plate activity room with a light weight, high strength, thermal insulation, aesthetics, durability, etc., is the integration of architecture and decoration, senior construction and installation fast. Choi activities of the steel construction cleaning, widely used in large-span factories, warehouses, office buildings, villas, roof and floor, air purification room, cold storage, shops, kiosks and temporary buildings. Light color steel sandwich panel meters weight less than 14KG can substantially reduce structural loads, reducing the activity room cost structure. Easy to install color plate activity room, light weight, installation and splicing can be arbitrarily cutting characteristics, determine its activities room installation is simple, and can greatly improve efficiency, save construction period. Fire color steel sandwich panel surface materials and insulation materials for non-combustible material, fully able to meet the activity room fire code requirements. Durable variety of studies have shown that after 40 years abroad widely used confirmed: color steel shelf life with a special coating in 10--15 years, every 10 years after spraying anti-corrosion coatings, activity room plate life of up to 35 years beautiful Pressure type color plate clear lines up to dozens of colors, can meet the needs of any style activity room of the building, to achieve satisfactory results. The color steel insulation composite board commonly used insulation materials are: rock wool, glass fiber cotton, polystyrene, polyurethane, etc., low thermal conductivity, and thus activity room with good insulation effect. High-intensity color plate with high strength steel for the substrate (tensile tensile strength 5600kg / cm) plus the most advanced design and roll forming. So color plate activity room with excellent structural properties. National standards and industry standard color plate commonly used: GB / T 12755-91 with a pressure-type color steel construction GB 6723-86 Universal type color steel cold-formed opening size, shape, weight and tolerances GB 50018-2002 Cold - Formed type color steel specification GB 50205-2001 color steel structure construction quality acceptance color plate steel sandwich panel specifications and performance specifications, performance: 1, color steel sandwich panel, often with tongue and groove plug-in, it has easy to install, saving time and material, good flatness and high strength, especially for ceiling, partition system. 2 thickness (mm): 50-250; 3, length (mm): Due to the continuous production of molded, plate length may be determined according to a user; 4, Width (mm): 1150 (1200) 5, core material performance: A, polystyrene bulk density: ≥15kg / m3 thermal conductivity ≤0.036W / mK maximum temperature: about 100 oC B, rock wool bulk density: ≥110kg / m3 thermal conductivity: ≤0.043W / mK maximum temperature: about 500 oC a | incombustible: B1 class B, non-flammable: a grade a, 950 corrugated board and corrugated steel sandwich panel set in one sandwich, a threefold increase in strength than the conventional flat steel sandwich panel, with hidden self-drilling screws and roof truss connection, without damaging the exposed parts of color-coated, extending the life of steel sandwich panel; board and the board connection using buckle hat, ease of construction, improve efficiency, the biggest feature is not easy to water seepage. B, rock wool insulation sandwich panels with a core material is basalt and other natural minerals as the main raw material, high temperature melting fibroblasts, adding an appropriate amount of adhesive curing process and made. The product is suitable for industrial equipment, construction, ship insulation, sound insulation, etc., apply to clean room, fire-proof workshop ceiling, partition and so on. C, PU polyurethane sandwich panels sandwich panel bonding strength of not less than 0.09MPa, sandwich burning properties of B1 level, flexural capacity of sandwich panel deflection (the distance between the seat of Lo) Lo / 200 when the sandwich flexural capacity of not less than 0.5Kn / m2
