Product Description:

Corrugated Pressed steel plate 820

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.

1.New fireproof rock wool sandwich board uses two-layer high quality colored steel sheet or other precision profiled metal plate as the panel board. After the board is rolled and shaped, stripped rock wool should be turned 90°(make its fiber perpendicular to upper and lower steel sheets), and then fire resistant bond with high strength and cohesion should be used for bonding the high quality rock wool with the metal panel together, thereby composing beautiful, smooth and rigid building board. The shaped board has excellent fire prevention, thermal insulation and environmental protection features and provides one superexcellent choice for industrial building enclosure system.
2. POILISOCYANURATE, abbreviated as PIR; composite boards developed by DUOWEI use excessive sulfone isocyanurate, so ring structure of chemical compound and higher sulfone isocyanurate index form the dense PIR, thereby making interior rigid foam more stable and have high heat resistance and flame resistance. Experiment shows that the bubble can endure 200 ℃ in a short time and can endure 160℃ in a long time.

Q:What kind of sheet is durable?
Surface materials to be smooth wear and tear, so that in the use of the object is not easy to wear off. Second, the internal core material splicing to be seamless, to pest control moisture corrosion. Huaxiang plate is very durable.
Q:Is there a sheet with a flame retardant function?
The market should still have a lot of, after all, now everyone's security awareness are put up. Before the concern of the wood industry's fire-retardant board seems to be doing this, you can see.
Q:I would like to know the lightest, most environmentally friendly, so beautiful and practical man-made sheet is what
Vientiane board inside the new ecological board
Q:Wardrobe to choose how thick the plate
Wardrobe sliding door generally choose 15mm, 16mm, 18mm of the majority of the plate.
Q:PCB board what
PCB board are: cardboard, resin board, metal substrate (aluminum plate), copper foil, ceramic substrate
Q:Want to change the pair of glasses frames, titanium is good or good plate, what are the characteristics?
Frames should be based on the face of the selection; face thin with a thin point of the frame is better. But also with the length of time wearing glasses also have to contact every day wearing a long time to choose a light point of the glasses, to avoid the nose pressure change type. In fact, the most important thing is the lens, the quality of things now vary widely, you have to choose a high light, wearable, safe, and their favorite. Also, male and female wear frames are not the same. Pure titanium, high-grade some corrosion-resistant, but also anti-magnetic. Large face of the plate do not use, round face is not appropriate. It is best to wear to see.
Q:Jin Lu Li plate quality
Bunny and Moganshan prices are relatively high, compared to the price of Jin Luli more suitable for mass consumption, my family and several colleagues are used Jin Lu Li recommended the use of gold Luli.
Q:Board grade divided into
According to state regulations, the environmental protection level of wood is divided into three categories: E0, E1 and E2. Environmental protection level E0 level: E0 level is the current national standards and related to the detection of ecological sheet of the highest environmental standards. Because the 0.5mg / l formaldehyde content is already a very safe numerical standard. According to relevant information, the formaldehyde content of drinking water is 0.9mg / l, that is, E0 grade formaldehyde content is less than drinking water. Environmental level E1 level: in accordance with state regulations, the indoor plate environmental protection level must be achieved E1 level was considered standard, that is safe and environmentally friendly, the human body will not cause harm. In recognition of the quality of the plate at the same time, the most concerned about the furniture used by the formaldehyde emission of sheet metal. E1-level environmental standards are mandatory national health standards, is mandatory "safety standard line." E1 <= 1.5mg / l, that is, 1.5mg / l formaldehyde content is in line with national standards, is environmentally friendly, harmless to the human body. Environmental level E2: E2 <= 5mg / l, E2 level of formaldehyde content has exceeded the national standard, the current production industry in the plate industry is very few E2 grade, E2 grade products must be treated after finishing to be used Interior decoration.
Q:I want to use EVA plate to do props. The The But how stereotypes ah?
Do props 13551 44205 here is really very tangled
Q:Woodworking four meters of the cabinet to a few sheets
