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:The steel structure of 40*80 steel, it is tempered glass top. The steel internal fight foaming agent. But there is rust in the inner surface. Will it affect the safety? How to deal with
This shows that the coating has entered the water or corrosive medium, and should not have much to do with the wall of the square pipe. Reasons for coating failure:1, the grass-roots treatment is not good. Steel structure shall be sand blasted.2, the selected paint should be better performance of anti-corrosion coatings, rather than ordinary alcohols and acids.3, must have primer, finish matching.4, coating thickness must be more than 200 microns in order to effectively prevent water penetration. The paint sprayed from you is likely to be caused by too much coating. Unless you spray it with airless spraying.
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
Also, I do not know whether you are welding stainless steel or iron, the novice can press the method to do, but ripe workers are visual, direct welding, of course, visual accuracy will always be a little worse,
Q:100*100*2.5 square with 20 square meters of housing security light steel structure:
Sun room safety also includes many other factors, such as the sun room design is reasonable, whether the material is special, the construction team is professional, and so on, to summarize the sun room safety including safety design, material safety, construction safety, maintenance safety. Consulting Zhejiang Baiyu Dinglong sun room can not understand the place, professional and technical guidance.
Q:The difference between square and square.
Square refers to the use of a square billet material rolled out, or by round steel after cold drawing process, the material out of the square. Formula weight: side length of square theory * * 0.00785=kg/m.
Q:What is the hot dip galvanized steel, production process?
Also called hot galvanized and hot dip galvanizing: hot dip galvanizing is an effective way of metal corrosion, mainly used for metal structure on the facilities of the industry.
Q:How to fix the steel Aluminum Alloy
Aluminium and steel welding now has two processes, one is explosive welding, which relies on the tremendous pressure caused by the explosion to weld the steel and aluminum plate together. The other is a diffusion welding, at a certain temperature, the steel and aluminum contact surface diffusion, diffusion layer is very thin in the joint surface, this time is longer, and the high requirements, generally in the equipment of.Melting welding is not yet implemented, plus transition plate is now a method, not the true sense of the aluminum plate and steel welding, but the transition plate is produced by the above two methods.
Q:How to ensure the steel paint off paint
Ensure the paint off square paint method:1, the steel brush must do the clean work before painting, there is no guarantee the steel rust or grease, the steel surface cleaning is the basis to ensure the paint off.2, must use special metal paint finishing of polyester type steel, to ensure no paint brush.3, paint to ensure that the film extended evenly.
Q:The difference between galvanized square and galvanized steel
There is a difference in the quality of classification and can be processed into cold and hot dip galvanized pipe, galvanized pipe, galvanized pipe and galvanized belt can not be made, because of its wall thickness is thin, so the price will take the price dip galvanized pipe is much higher than galvanized pipe.
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.
