Product Description:

Plate refers to the thickness of the steel plate thickness 4.5-25.0mm, 25.0-100.0mm called the plate, thickness more than 100.0mm for heavy plate.

Plate mainly used in construction engineering, machinery manufacturing,container manufacturing, shipbuilding, bridge construction. Can also be used to make containers of all kinds, the furnace shell, furnace plate, bridge and vehicle static steel, low alloy steel plate, ship plate, boiler plate, pressure vessel steel plate, checkered steel plate, automobile frame steel plate, someparts and components such as welding tractor. Through plate uses: widelyused to make containers of all kinds, the furnace shell, furnace plate, bridgeand vehicle static steel, low alloy steel plate, plate for bridge plate, boiler plate,made like, pressure vessel steel plate, checkered steel plate, steel, automobile crossbeam tractors some parts and welding component specific application.

Bridge

For large railway bridge plate, requirements under dynamic load, shock,vibration, corrosion resistance, such as Q235q, Q345q etc..

Shipbuilding

Used in the manufacture of marine and inland river ship hull, require high strength, plasticity, toughness and cold bending performance, welding performance and corrosion resistance are good. Such as: A32, D32, A36, D36etc..

Boiler plate (boiler plate): used in the manufacture of various boilers andimportant accessories, because of boiler plate at medium temperature (350degrees below C) under the high pressure condition of work, in addition toendure high pressure, but also by the impact and fatigue load and water andcorrosion, requests to guarantee a certain strength, but also have welded andcold bending properties, such as good: Q245R

Pressure vessel

Mainly used for pressure vessel manufacturing petroleum, chemical gas separation and gas storage and transportation and other similar equipment,the general working pressure and pressure to 320kg/cm2 and even to 630kg/cm2, temperature of -20-450 degrees to work in the range of C, the requirements of vessel plate except with certain strength and good plasticityand toughness, must also have good cold bending and welding properties,such as: Q245R, Q345R, 14Cr1MoR, 15CrMoR etc..

Q:What does steel plate "A3" mean?
Using Q235 steel as punch material, after quenching without tempering, direct use, hardness of 36~40HRC, solved the punch in use in the phenomenon of fragmentation
Q:What's the corrosion resistance of hot-dip galvanized steel sheet?
The surface coating of hot-dip galvanized steel can be anticorrosive
Q:What type of welding rod is used for steel Q245R and Q235B material?
Q245R is generally used in boiler or pressure vessel, if it is a large diameter cylinder welding body in wall thickness below 8mm recommended the use of arc welding J507 welding rod, double welding, carbon arc gouging back, to obtain qualifiedQuality; when the wall thickness is thicker, submerged arc welding can be used and welding with H08MnA welding wire and HJ431 flux is used;
Q:Stainless steel drawing plate, polishing plate, mirror panels of the three differences
Drawing process will to some extent lose the thickness of stainless steel plate, usually at 0.1~0.2mm. In addition, because the human body, especially the palm has a relatively strong oil and sweat secretion, stainless steel wire drawing board often hand touch will leave a more obvious fingerprints, regular scrub.
Q:Q235 is hot rolled steel or cold rolled steel?
Q235 hot rolling and cold rolling are available, depending on availabilityThe need for heating the material before hot rolling, rolling process or rolling, usually heated to above the recrystallization temperature, such as more than 1000 degrees; cold rolling is the process does not require heating of the material, or the material is heated to the temperature below the recrystallization.
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:What's the density of the 0.5 color steel plate?
We often see the color steel plate refers to the processing of sheet metal, the thickness of about 50~100mm, it is composed of the middle filler and two sides of color steel plate. Among them, the color plate thickness of 0.4mm, 0.5mm, 0.6mm and other different thickness, the middle layer can be polyurethane, rock wool or foam plastic. Because of the special profiles, the construction of the building with colored steel plate is very fast (such as the Xiaotangshan hospital in SARS), but the strength is low. The substrate of the color coated steel plate is a cold rolled substrate, a hot-dip galvanized substrate and an electro galvanized substrate. The coating types can be divided into polyester, silicon modified polyester, vinylidene fluoride and two plastic sol. The surface state of color coated steel sheet can be divided into coated plate, embossed plate and printed board.
Q:Larson steel sheet pile and what is the difference between the hot cold
Therefore, the same technical parameters, usually hot-rolled, will be slightly lighter proportion.For example, 14mm cold bend and 15.5mm SP-IV steel sheet pile, if they are 400mm width, cold-formed steel sheet pile will be heavier than hot rolled steel pileCold-formed steel sheet pile has 8-10mm thickness, although the product is light weight, but the technical parameters are correspondingly reduced.
Q:Is the steel plate 1.5 meters wide and 2 meters wide at the same price? .
The steel plate price is generally not the width, they only according to the different material steel plate, gives you to quote the unit price.
Q:What's the difference between profiled steel sheet and color steel plate?
A kind of color steel plate is in fact, but now the normal pressure plate to floor plate thickness in 0.7-1.5MM is used in galvanized coil is the main steel structure building, airport, train station, subway station, shopping malls, etc. some of the large span steel structure.
