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 is the thickness of the paint board?
Paint plate generally in accordance with the "block" as the unit sales, not only as a wall decoration, doors, tables and chairs can do the shelves, cabinets bearing surface, the thickness of 1-2 cm in length, 50 - 120, 30 cm wide case is 55*30*1.5cm
Q:What's the difference between a spray plate and a colored steel plate?
Color steel plate, material without zinc flower leveling, hot galvanized steel coil and zinc alloy coating, steel coil and other good substrate;
Q:What is a die steel plate?
The profiled sheet steel plate has the advantages of easy processing, light weight, fast installation, simple operation, and the tedious process of removing and dismantling the formwork.
Q:Q195 galvanized steel plate, is it hot or cold?
Cold rolling mill for rolling power, low efficiency, and the rolling process in order to eliminate work hardening and annealing, so the cost is higher, but the cold rolled steel surface bright, good quality, can be directly used for processing products, it is ten points wide application of cold rolled steel plate.
Q:What do you pay attention to?
1, the plastic bumper with 150-320# sandpaper, if the upwarping phenomenon in the injured, also with a knife will become warped skin scraping.2, in addition to oil, dust, after the proportion of the mixture of good ash fill the depression, to dry solid, first with 320-400# sandpaper polished, and then use 600-800# sandpaper grinding.3. After drying, place a primer newspaper at about 40mm of the ash.4, after removing oil and dust, with diluted primer (primer and quick drying diluent ratio of 1:1), empty spray again, dry and then spray again. In order to reduce the number of spraying and grinding time, it is necessary to ensure the smooth flow of primer, without flashing between each time. Dry the surface of the paint film, until the primer lose brightness, you can continue spraying, and then go round and round until you reach the thickness of the depression.5, in order to shorten the volatilization time, can use high temperature equipment baking, do not have to remove the newspaper, dry solid with 600-800# sandpaper to throw flat, but must not wear primer layer leakage.
Q:Is the cold rolled steel plate good or the stainless steel plate?
The cold rolled steel itself, whether washed by acid car wash, semi-finished products, or rolled out by cold rolling mill semi-finished products, their rust resistance is very poor. It is easy to oxidize, resulting in rust on the surface of the air. It will not rust until it has been plated with aluminum or zinc, and it is clear that the process is complex and unsafe.
Q:Can 16Mn steel plate be used instead of Q345D steel plate?
16Mn steel plate is the old brand, the latest brand is Q345, but Q345D has a special requirement than 16Mn, that is, 20 degrees lower temperature test
Q:How is the normalized steel plate produced?
Normalizing, also known as normalizing, is to heat the workpiece between 727 and 912 degrees Celsius. 40~60min, after a period of heat preservation, is removed from the furnace and cooled by air or by spray, spray, or blow cooling. Its purpose is to make grain refinement and carbide distribution homogenization, to remove the internal stress of materials.
Q:What kind of steel plate is HIC?
Is suitable for use in acidic environment, hydrogen sulfide corrosion resistance of the steel plate. Also known as hydrogen or hydrogen resistant steel, generally pressure vessel or pipe steel.
Q:Is galvanized iron sheet the same as galvanized steel sheet? solve
Galvanized sheet iron and galvanized steel sheet is a kind of thing. Galvanized iron sheet is commonly used as galvanized steel sheet. It is not a strict scientific name.
