Product Description:

DUOWEI profiled sheet-composite slab, as permanent form in construction stage, bear construction load and concrete weight. In use stage, the profiled sheet will be used as the bottom reinforcing bar and will generate composite effect after concrete reaches the strength.

Eight advantages

There are pre-processed slots between the corrugations of the profiled steel plates, available for engineering use like electric power and communications.

The dead load of the entire structure is reduced, saving the basic cost of the lower part.

During construction, the profiled steel plate can enhance the lateral stability of the supporting steel beam.

It gives full play to the mechanical properties of two materials - steel and concrete.

It does not require formwork, getting rid of the removal and installation of formworks.

The profiled steel plate is equal to tensile main rib based on calculation, only moisture reinforcements are needed.

The profiled steel plates provide an even ceiling surface for concrete buildings.

After installation, the profiled steel plate can be used as a safety work platform for workers, tools, materials and equipments.

Eight major characteristics

Strong concrete bond shear resistance
With Special closed-rib design, good longitudinal shear-bearing capacity, there has never been slippage between the steel bearing plate and the concrete upon closed built-up slabs within design load limit.

Excellent fire performance
The ribs of slab are completely encased in concrete, just like the cast-in reinforcement. Closed built-up slabs can completely replace the positive moment tensile reinforcement in the floor slabs, and an 1.5-hour refractory power can be achieved without need to brush fire-resistant coating

Superior section of built-up slabs
Closed built-up slabs have a higher effective height of the floor slab and a bigger combination stage to provide a more powerful positive moment resistance.

Board(Slab) end slot-type suspension system
For the use of ceilings, ceiling, plumbing installation, etc., no need of drilling or welding; during the building period, it can be moved, removed or reinstalled, according to the need.

Simple, rapid construction
It does not require any plug, with no leakage of mortar, available to shorten the construction cycle.

Even slab bottom appearance
The slab bottom is even, it is beautiful for the buildings not planned for the ceilings .

Effectively reduce the slab height
According to fire regulations and shatterproof requirements, the total thickness of the closed built-up slab is only 110-130 mm, 30-40 mm less than the opening profiled steel plate composite slab, thus getting a reduced self weight, reduced costs, and increased height.

Low cost
The reinforcements bearing the positive moment of the closed built-up slabs are replaced by the profiled steel plates, without need to brush fire-resistant coating, thus reducing the usage of reinforcements and cutting down the costs.

Q:Are man-made sheets containing formaldehyde?
Man-made sheet containing formaldehyde: Because the plate, MDF, particleboard, wood flooring and other man-made sheet of formaldehyde mainly produced in the manufacturing process from the bonding of formaldehyde resin. This resin has a strong adhesion, to strengthen the hardness of the board, pest control, anti-corrosion function and cheap, is the first choice for the man-made sheet of raw materials. As the formaldehyde in the floor will not immediately volatilize, but because of different temperature and humidity conditions slowly volatile, volatile time up to ten years.
Q:What are the differences between FR5 sheet and FR4 sheet?
FR-5 has better advantages than FR-4: 1, TG, TD higher; 2, better heat resistance, about twice the normal FR-4; 3, Z-CTE smaller, suitable for high Laminates; 4, T288 better.
Q:What are the types of closet panels, there are several paint-free board?
Classification of paint-free panels 1, high density paint-free board High density paint-free board price is low, it is 3mm board as the substrate, a layer of plastic mask. If you can do it yourself, you can do it yourself. 2, foam paint-free board Foam-free paint plate high price, flexibility is better, it is a thickness of about 2.5mm foam material for the substrate, a layer of mask-free film. Easy to work some, but the surface is softer, the use of finished products to be careful. 3, polymer Mianqi board Polymer Mianqi board high price, thickness of about 2 mm, its matrix and the surface is a polymer material. Made the product effect is good, high grade, but the higher cost of workmanship and materials.   4, other Mianqi materials Fire board, Boeing film. Fire board low price, friction, easy to clean, generally used for shoe and cabinets; Boeing film easy to use, available inside the wardrobe.
Q:E0 and E1 grade plate how to distinguish?
In fact, the grade of the plate refers to the finished sheet containing formaldehyde content of the level, which E0 level for the most advanced, the highest environmental index, with the least amount of formaldehyde, ≤ 0.5mg / L (belonging to the world's top standard); followed by E1, 1.5mg / L (in line with European standards); E2 level ≤ 5.0mg / L (in line with domestic standards). Although the higher the level of the amount of formaldehyde containing less, but also pay attention to the number of use, not because of environmental standards on the unlimited use, because the housing space is fixed, and the amount of superposition will make environmental protection exceeded. In addition, because the E0-class plate itself does not contain adhesives and moisture-proof agent, so its relative moisture resistance and toughness will be reduced, so not suitable for use in the kitchen, bathroom and other humid environment.
Q:What kind of furniture are all kinds of furniture ah?
Generally divided into solid wood and man-made sheet. Solid wood is a natural solid wood sheet, this is easy to understand. Man-made sheet is divided into many categories. 1, multi-layer plywood. 2, Blockboard is the big core board. 3, high density board fiberboard (high density board) 4, solid wood particle board. 5, particleboard. 6, moisture board and so on
Q:I am looking for a sheet of material that requires a lighter than the aluminum alloy 7075 material, strength, is the name of this material?
7075 aluminum alloy is Al-Zn-Mg-Cu super-hard aluminum, 7075 alloy is the late 1940s has been used in the aircraft manufacturing industry, is still widely used in the aviation industry, ultra-high strength deformation of aluminum alloy. It is characterized by good plasticity after solution treatment, good heat treatment strengthening effect, high strength below 150 ℃, and particularly good low temperature strength; poor welding performance; stress corrosion cracking tendency; need to be covered by aluminum or other Protection processing use. Two - stage aging can improve the ability of alloy to resist stress corrosion cracking. In the annealing and quenching state of the plastic slightly lower than the same state of 2A12. Slightly better than 7A04, sheet static fatigue. Notch sensitive, stress corrosion performance is better than 7A04, of which 7075T651 state is particularly top grade, known as aluminum The best products, high strength, far better than soft steel. This alloy has good mechanical properties and anodic reaction, is a typical aerospace aluminum alloy material.
Q:What are the types and specifications of wood?
Divided into: Blockboard, plywood, laminated board, particleboard, MDF, decorative panels,  1. Blockboard: Blockboard Commonly known as the big core board is made of two pieces of plastic plate from the middle of stamping wood.

Q:How much is the quartz stone plate? What is the specification?
See how much you want, and wholesale prices and agency prices are not the same, generally about 170 in a square bar Now on the market cabinet specifications are generally 2440 * 750-760 * 15mm, large board is generally 3200 * 1600 * 15mm, these two are standard board. Generally have to 3100 * 1500 * 15, the size of foreign are generally 20mm thick.
Q:What is the material of the Margaret Wardrobe?
This, all the current wardrobe are either using the plate, or the use of solid wood, or the use of solid wood composite. In general, the solid wood composite to be relatively better. As for the brand, this look at your budget, the better point of the Margaret, Europe and so on, if the budget is sufficient, then you can choose this category specifically for the villa wardrobe Manloi; of course, foreign brands of Chinese goods is relatively good consideration
