Q:Round and square steel which is strong
From the round and square steel specifications and appearance quality of the steel, 1. force large contact surface and relatively small pressure, 2. and three provide support force and the force behind. The force contact surface of round steel is very strong.
Q:Are square steel, rectangular tube and angle steel shaped or light steel?
Square steel, rectangular tube and angle steel belong to section steel, light steel and section steel are not tied together.1., light steel is also a relatively vague term, generally can have two kinds of understanding. One is the current "code for design of steel structures" (GBJ 17-88) in the eleventh chapter "bar, small angle light steel structure", refers to the use of steel and light steel structure is less than L45*4 and L56*36*4 angle steel production, mainly in the lack of time for small steel structure manufacturing of reinforced concrete structure should not be used, has been basically not used, so the revised code for design of steel structures has been basically removed this tendency. The other is the "Regulations" technology of steel structure of light-weight buildings with gabled frames with light roof and wall light (also has the condition to use the masonry wall) single portal frame structure, the light here mainly refers to the enclosure is made of light material. Since the former has been cancelled soon, the meaning of "light steel" mainly refers to the latter
Q:How to ensure the steel paint off paint
The first thing to do (clean dust, oil removal, in addition to soluble salts), and then choose to kill or polish, then under suitable conditions (humidity is less than 85%, the substrate temperature is higher than the dew point of at least 3 degrees Celsius) and construction paint. Well done, the paint won't fall off.
Q:Why is a point of penetration of 2 square steel welding
With 2.5 of the electrode try, I solder 1 will do, hand gestures as soon as possible, it is not so easy to point out the hole, if the conditions can choose carbon dioxide protection welding, but the cost of welding should be high
Q:Building with steel or steel plate?
It is recommended to use channel No. 12, and the span of three meters is not big, so the problem of vibration will not occur! Square steel tubes are not recommended for load-bearing structures. I'm from the steel installation department.It is suggested that the upper channel, the red plate, and the wood. It's more comfortable to use.
Q:What is the cold drawn steel material? Why did it break?
Should be low carbon steel, easy to break, because the carbon content of steel or impurities too much, but also later that its ductility is not good, in addition, low temperature is also easy to break
Q:How the steel columns and I-beam steel structure connection?
Steel structure engineering is mainly made of steel, and it is one of the main types of building structures.
Q:4 x6 1.5 square meters thick, how much money
1, the steel prices generally calculated in tons. To see you say the steel is hot dip galvanized or black material.2, hot galvanized general 4500/ tons,3, black wood generally in 3800/ tons.That is 4.5 yuan /kg and 3.8 yuan /kg. Forget it. You say this kind of steel is 2.355kg per meter,
Q:The moment 2mm thick galvanized square steel tube using what welding methods
Galvanized square tube adopts gas shielded welding, conventional J50 gas shielded welding wireArgon arc welding galvanized square pipe, zinc burning more severe, not recommended
Q:Twist steel (twisting steel) there is no standard?
Lattice steel plate steel bar is also called twist, the steel twisted shape, so only when the square size annotation annotation, common general specifications for 8*8mm, 6*6mm, 5*5mm, in the standard steel plate, the bar is defined as fixed on the bearing flat steel, round steel, square steel twisted or flat, that is say, don't necessarily use twisted steel (steel twist) but hot dip galvanized steel grid plate used in the steel industry used torsion, stainless steel using round steel, and make use of flat bar made of steel plate. We called steel grid plate or pressure locking steel plate, steel plate of GB also do this cross sectional area:: twisted steel, round steel bar with flat steel, its cross-sectional area of not less than 20 mm.
