Light steel keel is produced by Light Steel Keel Roll Forming Machine, which is a new type of building material, with the development of modern construction in China, light steel keel is widely used in hotels, terminals, car transport stations, stations, playgrounds, shopping malls, factories, office buildings, old buildings building renovation, interior decoration settings, roofs and other places.
Light steel (baked paint) keel ceiling has light weight, high strength, adapt to waterproof, shockproof, dustproof, sound insulation, sound absorption, constant temperature and other effects, but also has the advantages of short construction period, easy construction and so on.
Light steel keel has ceiling keel and partition keel according to the use, and V, C, T, L and U keel according to the section form. The order of marking of light steel keel is: product name, code, width of section shape, height, thickness of steel plate and standard number. If the section shape is "C", the width is 50mm, the height is 15mm, the thickness of the steel plate is 1.5mm, the ceiling keel is marked as: light steel keel for construction.
The appearance of the light steel keel should be flat, with clear angles and no burrs or deformations in the cutout that affect the use. The galvanised layer is not allowed to have defects such as peeling, tumouring or peeling. For defects such as corrosion, damage, black spots, pockmarks, etc., the test shall comply with the provisions of Table 2-81 when tested according to the prescribed method. Visual inspection should be carried out under bright lighting conditions at a distance of 0.5m from the product when checking the appearance quality.
The surface of the light steel keel should be galvanised to prevent rusting, and its double-sided galvanisation amount: not less than 120g/m*m for superior quality The painted keel The painted keel is made of fireproof galvanised sheet, which is durable. Adopt economic placement structure, special connection method, combination loading and unloading. Convenient, time-saving and simple construction. The surface of the keel is made of galvanised steel with a baked-on finish.
The difference between the light steel keel and the painted keel is that the general light steel keel is that the general light steel keel does not have a painted surface, but a plated surface (galvanised), while the painted keel has a painted surface, usually in black and white, with a few other colours according to design requirements.
The main reason is that most of the painted keel is used in the open keel, the paint is to ensure that the exposed part does not affect the aesthetics if it is not rusted. Open frame keel Flat series, grooved series, three-dimensional grooved series.
Concealed Frame Keel : flat series The painted keel has a good overall flat effect, with simple and beautiful lines. The painted keel is safe, sturdy and beautiful and is suitable for the construction of various mineral wool ceilings, aluminium square ceilings and calcium silicate panels.
With light weight, high strength, waterproof, fireproof, shockproof, sound insulation, sound absorption and other effects, but also has the advantages of short construction period, easy construction, is a new type of ceiling decoration materials, widely used in shopping malls, hospitals, banks, hotels, factories, terminals, etc.. The main specifications of the partition keel are Q50, Q75 and Q100. The main specifications of the ceiling keel are D38, D45, D50 and D60.
