Q:Must the welding between steel sheets be opened?
But thicker plates, such as 12mm or above, are difficult to guarantee welding qualification even if they are welded with SAWYour problem may be welded on the unprofessional people say, feel good on the surface of welding ends, not the same? In fact, welded or esoteric, without welding, or cracks and other defects, the strength will be greatly reduced, and the use of steel plate are generally in force or place very good welding pressure, it is easy to have an accident.
Q:What are the driving methods for steel sheet piles?
Mechanical hand general construction pile length of less than 12m steel pile; more than 12m length generally use crawler crane combined with vibration hammer construction, if the surrounding environment is sensitive to vibration, can use Japanese static pressure pile driving machine construction. The vibration hammer: DZ40 DZ45DZ60 DZ90 DZJ120; ordinary steel sheet pile, DZ60 type vibrating hammer.
Q:Is color steel plate the same as color steel tile?
Tile color steel tile is used for color coated steel plate, pressure plate and the roller of cold bending into various wave types, it is suitable for industrial and civil buildings, warehouses, special buildings, large-span steel structure house roof, walls and wall decoration, has the characteristics of light weight, high strength, color rich, convenient construction, affluence earthquake, fire, rain, long service life, maintenance free, have been widely applied.
Q:Who knows the wire width of the steel mesh?
Steel wire should be called stem stem.
Q:What is steel concrete?
Steel plate concrete is generally called SRC, that is, the steel part is changed into steel plate, basically the concrete is poured on the steel plate. Specific reference, construction manual fourth edition.
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:Excuse me, what's the difference between cold rolled steel plate and hot plate in steel plate?
In general, cold rolled steel has better strength, hot rolled steel plate has better ductility. The general thickness of cold rolled is relatively small, can have a larger thickness. Cold rolled steel plate surface quality, appearance and dimensional accuracy than the hot plate, and the thickness of the product right rolling thin to about 0.18mm, so it is popular for. The acceptance of the products, can ask professional personage.
Q:What does "rolled steel" mean?.
Rolling is a rolling process, the plate is kind of calendering material, not only some specific material, it can contain stainless steel and carbon steel materials, stainless steel with thickness of steel production for example, now the tolerance basic law, but in order to achieve a certain thickness
Q:P355NL1 what kind of material is the steel plate?
Use: used in petroleum, chemical industry, power plant, boiler, for the production of reactor, heat exchanger, separator, tank, oil tank, liquefied gas, nuclear reactor pressure vessel, boiler, liquefied petroleum gas bottle, hydropower station high pressure pipes, turbine volute equipment and components.
Q:Can the steel sheet pile retaining structure be watertight and impervious?
If the channel is certainly not, but Larson type steel sheet pile is able to, and the effect is not bad.
