What is the light steel keel?
Paint keel features and uses
(1) absolute fire: paint keel is a fire galvanized sheet manufacturing, durable.
(2) reasonable structure: the use of economic placement structure, special connection method, combined handling. Convenient, save time, construction is simple.
(3) handsome appearance: keel surface is used galvanized steel, after the paint treatment.
(4) widely used: for shopping malls, office buildings, hotels, restaurants, banks and large public places.
Classification
Gantry keel: flat series, groove series, three-dimensional groove series. Dark keel: flat series
Paint keel overall plane effect is good, simple lines, beautiful and generous. Paint keel safe, sturdy, beautiful, suitable for all kinds of mineral wool ceiling, aluminum cubes ceiling, calcium silicate board and other supporting construction. It is a new type of ceiling decoration material, widely used in shopping malls, hospitals, banks, hotels, factories, factories, factories, factories, factories, factories, factories, factories, factories, factories, factories, factories, factories, factories, factories, factories , Terminal and so on.
Light steel keel according to the use of hanging keel and cut keel, according to cross-section of the form of V-type, C-type, T-type, L-keel.
(1) product specifications series of keel main specifications are divided into Q50, Q75 and Q100. The main specifications of the ceiling keel are divided into D38, D45, D50 and D60.
(2) Product marking method The marking order of light steel keel is: product name, code, width of section shape, height, thickness of steel plate and standard number. Such as cross-sectional shape of "C" type, width of 50mm, height of 15mm, steel plate thickness of 1. Smm of the ceiling keel marked as: building light steel keel DC 5 0 XIS XI. SGBllg sl
(3) the appearance of quality light steel keel shape to be smooth, angular, cut not allowed to affect the use of burrs and deformation. Galvanized layer is not allowed to have skin, from the tumor, shedding and other defects. For corrosion, damage, dark spots, pitting and other defects, according to the provisions of the method should be tested in accordance with the provisions of Table 2-81. Appearance quality inspection, should be 0.5m away from the product under the conditions of bright light, the visual inspection. Light steel keel surface should be galvanized rust, the double-sided galvanized: excellent products not less than 120g / m * m, first-class goods is not less than 100g / m * m, qualified products not less than 80g / m * m.
Paint keel with cold-rolled continuous hot-dip galvanized steel strip and paint belt as raw material, through the cold bending process, composite rolling from a reasonable "T" -shaped structure of the thin-walled profile.
Light steel (paint) keel, is a new type of building materials, with the development of China's modernization, in recent years has been widely used in hotels, terminals, passenger stations, stations, theaters, shopping malls, factories, office buildings, old Building renovation, interior decoration, roof and other places. Light steel (paint) keel ceiling with light weight, high strength, to adapt to water, shock, dust, noise, sound absorption, constant temperature and other effects, but also has a short duration, easy construction, etc., by the user and the design unit widely used. Light steel keel and paint keel is the difference between the general light steel keel is not painted surface treatment, making coating (galvanized), and paint keel surface made paint, generally divided into black and white, a few according to the design requirements baked into other colors, Mainly because most of the paint keel used in the Ming keel, paint is to ensure that the exposed part of the rust does not affect the appearance.
