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
The rust removal on the inner wall of pipe profiles has always been a thorny problem. If the corrosion is not serious, the treatment is usually not done. If you want to anti-corrosion effect is good, but also to go inside the paint corrosion prevention practices, very few.
Q:How to connect with steel purlin roof
The canopy is divided into two parts, one is the structure of part two is part of enclosure (that is, roofing materials, such as glass, aluminum plate, color plate etc.)
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:
The span of the main girder in the sunlight room is 20 square meters, but the different shapes lead to the different span of the main beam.
Q:How to hollow square steel welding
Welding welding of thin-walled square steel, should be very careful when welding, arc welding technique should be used to pick, watch live pool, found that the weld pool collapsing must be timely arc.
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:It can be used as the steel electrical equipment grounding
In the electrical grounding body, generally use the steel pipe, angle steel, flat steel, round steel and other steel specially made grounding. The artificial grounding body and the ground wire form a grounding device, so that various earthing of the electrical equipment is connected with the ground through a grounding device. The artificial earthing body has two kinds of vertical embedment and horizontal embedment. The vertical buried pipe, angle steel, round steel grounding body, and have sufficient mechanical strength; ground level buried body with round steel, flat steel, common type, with several ring and radiation type. It is better to use galvanized steel when laying artificial earth in strongly corrosive soil. The steel used in the earth body shall be in accordance with the requirements of thermal stability and uniform pressure.
Q:What is the use of square steel keel or welding steel canopy
Sunshine board: advantages and characteristics of canopy cover top plate endurance detailed materials: flame retardant of spontaneous combustion temperature of 630 DEG C PC endurance board (wood 220 degrees C), by the national quality supervision and testing of fire building materials testing center, PC board of GB combustion (8624-1997 flame retardant grade B1), which belongs to the flame retardant engineering materials. Chemical corrosion resistant PC resistance board has good chemical resistance and corrosion resistance. It can resist all kinds of organic acids, inorganic acids, weak acids, vegetable oils, neutral salt solutions, aliphatic hydrocarbons and alcohol at room temperature. Heat resistant and cold resistant PC endurance board has good resistance to temperature difference. It can adapt to all kinds of severe weather changes from cold to high temperature. It can keep all kinds of physical performance indexes stable between -40 and 120 degrees centigrade. The photochemical PC resistance plate has the highest transmittance in visible and near infrared spectrum. Depending on the color, the transmittance is up to 12%-88%.
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: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.
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.
