Q:Building height is 5m, the main dry hanging stone square spacing value should be how much better?
Man, I specialize in this industry. You are not very clear, some data depends on how thick you use, what specifications of stone. More important is to see how large the main keel (channel or Fang Gang) you use, and how far the stone faces are separated from the structural surface.
Q:The steel structure material can do
The square can be built steel shed, small steel shed are built with square, purlin is divided into 98% major plant two 4*6 and 4*8 5*10 are not a pillar or beam with the tube, because not standard
Q:The water was poured into the square on how to prevent rust after treatment
The steel should try to avoid the rain, if you have been caught in the rain, according to the properties of the steel is not the method to wipe, such as high hardness steel wire brush, cloth, cotton and other materials of low hardness.
Q:The joiner board is fixed on the square on how
With self tapping screws, that is, with drill screws, building materials market can buy. Electric screwdriver, you can put the wood board through self tapping screws into the steel. But attention should be paid to buy the self tapping screw length, short patch does not live too long into the square, too much is not good.
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
1 current 60-80, air flow 0, 5With 2 plates and square steel welding and 1 identical, square and square steel welding current is available in 120, with stronger welding flow unchanged.30, 2 of the plate welded iron angle iron, it is difficult to weld, the plate is too thin.4, black needle and gun mouth flat, go in a little can also.5 general gas stations are filled with large bottles of change. 13 presses per bottle. 8L only do the spare, easy to carry, only do the skeleton and winding, spot welding, sealing up can do 40 to 50.7 welding galvanized sheet iron with a lot of trouble. Try it and you'll see. The iron steel welding line, is not strong.
Q:What is the cold drawn steel material? Why did it break?
This should be the problem of raw materials, raw materials are hot-rolled round steel or steel, raw material impurities, there will be extended by cold drawing fracture phenomenon. Materials for large steel mills are proposed.
Q:The difference between the steel chrome and paint
General steel can paint and painting the door company most paint steel, but you must ask whether to do heat treatment, because the paint is paint backward Hongfang heating paint drying process.
Q:The anti-theft lock in the steel compression spring is what?
The use of stainless steel spring wire suspension spring wire is advanced, high strength, long fatigue life, the effect is good damping characteristics, spring steel wire, the number and distribution of inclusions, so the chemical, high surface quality, decarbonization, microstructure and mechanical performance requirements.
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 difference between cold and hot galvanized steel hollow where
Cold rolling process is: the strip through the mold, pipeline bending forming, and then through the automatic welding, the welding joints, and then polished, galvanized, also called seamed tube.
STEXIN, an enterprise specializing in the production and sales of square bar, round bar and flat bar. The annual production capacity of square billet is 60,000 mtons, and sturtual steel 80,000 mtons.
