Q:What do you pay attention to?
Considering the quality factor, quality of the primer must have good corrosion resistance, and the old paint film or metal layer has good adhesion, excellent filling force, smooth surface; from the construction perspective, quality should be applied to the body of the primer, vehicle repair and local repair; from the view of time and operation high quality, primer volatilization and shorter drying time and simple mixed paint; considering body material, quality repair primer should be used for the old paint, aluminum, galvanized steel, stainless steel, fiber, plastic products, hard wood, putty and other substrates.
Q:What does "Z" mean to the performance of steel?
To apply for Z steel plate thickness and subjected to tensile load on just the thickness direction has the performance requirements, it is in a certain level of structural steel (called parent steel) on the basis of the special treatment (such as calcium treatment, vacuum degassing, argon stirring etc.) and proper heat treatment steel.
Q:What is a fixed length steel plate?
Such as steel plate, its fixed length is six meters, then it is 6 meters, the size will not be uneven. The standard size of the general steel plate is determined according to the national standard, such as 6 meters, 9 meters, etc..
Q:How do you calculate the square footage of a ton of steel?
It is made of molten steel and cooled and pressed into flat steel.The steel plate is flat, rectangular, and can be rolled directly or cut from a wide strip of steel.Steel plate by thickness, thin steel plate <4 mm (thinnest 0.2 mm), thick steel plate 4~60 mm, extra thick steel plate 60~115 mm.The steel plate is divided into hot-rolled and cold-rolled parts according to rolling.
Q:What are the driving methods for steel sheet piles?
The construction of steel sheet pile mainly consists of mechanical hand, crawler crane, vibratory hammer and static pile driving machine.
Q:Can 16Mn steel plate be used instead of Q345D steel plate?
16Mn steel plate, equivalent to Q345A steel plate, can not be replaced.
Q:What's the difference between steel plate 20 and Q235 steel plate?
In the normalizing state of No. 20 steel, the yield point is 245MPa, the elongation is >25%, the quenched and tempered state, the yield point is 280MPa, and the elongation is >22%. Widely used in the production of small, high load toughness requirements of parts, such as rod, heavy and general machinery in forging the sleeve, fixture and liner, general machinery and automobiles and tractors in small parts of carburizing, cyaniding.
Q:Is 5mm thick steel plate tapping M8 thread reliable?
The pitch of the M8 is 1.25, it can attack 4 teeth. The force of the thread is 4-5 teeth. The bottom is not greater than 6.7mm, 8.8 plus elastic pad bolt.
Q:What is the thickness of the water resisting steel plate of the electrical outlet?
Water blocking plate is made of stainless steel plate overall customization, visibility and strong practicability, top post reflective strips into professional production engineering grade reflective film, reflective film with gummed paper durable.
Q:What's the difference between low carbon steel and cold rolled steel?
It is usually used for cold rolled, low carbon steel for cold rolling, high carbon steel, generally not suitable for cold rolled steel plate, of course, this does not mean it completely just cold rolled steel of low carbon steel, because of the addition of alloy elements in all kinds of low carbon steel alloy steel can be different, such as P-added high strength steel, high strength low alloy steel after cold rolling after the steel is cold rolled steel grades, is just not the same.
