PU Sandwich panel (Polyurethane sandwiched panel )is composed of 2 layers of weather-proof colored steel sheets and jetted the hard forms of polyurethane between 2 layers which feature fireproof materials. It is suitable for the various roofs and walls referring to the large-size factory buildings, storages, exhibition halls, gymnasiums, freezing stores, purifications workshops, etc, which features temp-keeping, heat insulation, weight-bearing, weatherproof with the rich colorfulness and good appearance.
PU insulation sandwich panel
PU board adopts quality raw material from BASF which guarantees the qualtiy of foamed boards.
The board is formed in one time by pressure injection machine with color steel sheet or stainless steel sheet on both sides.
The polyurethane inside is spread evenly which guarantees a high efficiency in thermal insulation and lowers cold consumption, thus, the customers operation cost is
pu panel sandwich
PU Sandwich Panel(Width 1000mm,100mm)
1, the quality of light weight per square meter of less than 24kg, can reduce the cost of the structure.
2, quick installation of light weight, splicing, installation and can be arbitrarily cutting characteristics, determine its installation is simple, can improve efficiency, save the time.
3, fire, Caigang composite plate core surface materials and insulation materials for the non-fuel or burning material, can meet the requirements for fire protection.
4, refractory, with a special coating color steel plate and the new 10-15 years, after every ten years spraying anti-corrosion coating, sheet life over 35 years
5, beautiful, pressure plate clear lines of dozens of kinds of colors, can be matched with any style of the building takes
6, insulation insulation material commonly used are: rock wool glass fiber, cotton, polystyrene, polyurethane, low thermal conductivity, good thermal insulation effect.
7, environmental noise prevention, composite board insulation strength up to 40-50 dB, is very effective sound insulation materials.
8, strong plasticity sheet steel can be cut, enough to meet the special design needs.
9, high strength with high strength steel plate as a substrate, the tensile strength of 5600 ( kg / cm2 ), plus on the most advanced design and roll forming, and has excellent structural properties
1) sandwich panel used in large industrial plants, warehouses, supermarkets, hospitals, stadiums, cold storage, activities room, buildings plus layer, clean workshop and heat insulation fire place.
2) sandwich plate appearance, bright color, good overall effect, it sets the bearing, thermal insulation, fireproof, waterproof in one, and no two decoration, is a widely used, especially in the construction site of the temporary facilities such as office, warehouse, walls, but also embodies the modern construction site civilization construction,
3) in the fast installation and put into use, the assembly and disassembly, material turnover multiplexing index, have obvious advantages, greatly reducing the construction site temporary facilities, will be indispensable new lightweight construction materials
This kind of pu sandwich panelhas characters as follows:
1. steel strip:up/bottom 0.3- 1.2mm colourcoated steel panel/zinc plate,hot galvanized plate/stainless steel plate
2. core material: density of PU:30-80kg/m3
1.T he applicable width of interface;950mm,1150mm
3. no length limit.
product perfomance: light and durable,easy to install, large usage
Usage: This kind of sandwich panel can be used in steel structure workshop,easy building and air clean room as walls ,ceilings. Especially for cold storage
1. Professional design and engineering team: Full solution for site camp design. We could make the design for whole camp as per your requirement.
2. Procurement and Manufacture for all material for prefabricated building. We have a professional procurement team to make sure all the materials are with good quality. And our factory operation under ISO standard, to make sure the fabrication works with high technology.
3. Site management & Installation supervision, We could send our engineers to help for the installation supervision, you just need to prepare a team which know normal construction works will be OK.
4. Engineer guider : When construction need , we can arrange engineer guider to help you , and also offer detail construction drawings for you .
Why Choose Prefabricated house for Site Camp Solution? There are many advantages to modular camp construction for site camps including:
1. Speed of construction and camp installation Allows for the building and the site work to be completed simultaneously, reducing the overall completion schedule, all the Main Structures will be connect with bolts, no welding works. All the wall and roof structure, flooring will be fixed by Self-tapping Screw or nails, normal Carpenter team could make a good job!
2. Economical Solution, compare to concrete building, prefabricated building will be much more Economical
3. Ability to service remote locations Assembling a work camp close to the work site reduces travel time which reduces cost.
4. Long time span Well-built modular worker camps can last for 10, 15 or 20 years or more.
5.Safe and stable, Earthquake resistance: Grade 7, Wind resistance: Grade 11(wind speed≤ 120km/h)
In general, for steel structure , we use the steel frame packing to keep goods not to be broken . For sandwich panel and color steel sheet, we use the factory packing which is suited to transport. if clients require , also can use the steel frame packing or according to customers’ requirements.
