Q:The difference between cold and hot galvanized steel hollow where
Hot rolling process is: the ingot directly into square tube, and then galvanized, also known as seamless pipe.Usually than cold-rolled steel hot-rolled square steel prices high.
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:Reinforced concrete and steel stairs to do the stairs which is better
Square is a square cross section of steel bars (square steel), not rectangular steel tube, can not do the stairs.
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
You can't weld well without using tools, and it can't be welded with high quality. If the site is large and batch welded, you can use wood as a standard corner frame (quite a template). ), if the amount is small, you can buy a wooden triangle plate, steel square to live, post welding,
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:What is the role of square toilet
Toilet partition ground material: ground should use waterproof, dirty, anti-skid granite, etc., the height should be lower than other ground 10---20mm, floor drain should be less than 10mm, in order to facilitate drainage.
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:4 x6 1.5 square meters thick, how much money
The steel prices generally calculated in tons. To see you say the steel is hot dip galvanized or black material. Hot galvanized general 4500/ tons, 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. You can tell by your own price.
Q:You need to light steel keel wall square steel
Needed. The material of the light steel keel partition wall is galvanized iron plate, the pressed keel and the gypsum board (or calcium silicate board), its merit is the light weight, easy to walk the electric wire tube, the construction is quick. But the fire is not good, it is dry work. The cost is higher.
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
