Q:What is the use of square steel keel or welding steel canopy
Canvas awning: crank arm type retractable awning is in a separate structure, relatively safe, without the square tube, no paint spray, arm firmly and focus on both sides of the steel plate bracket, if the canopy length of more than 5m, the increase of direct arm assembly and focus on the middle support, on both sides of the iron with expansion screws are mounted directly on the solid wall, or welded firmly in indirect metal frame, the installation conditions need to pick out the roof, or rain gear plate, telescopic arm type awning is a retractable awning can be arbitrarily different stretching length, wind speed Aluminum Alloy bracket can withstand 50KM/ph. Maximum size of up to 18 meters wide, stretching length of up to 1.5 - 3.5 meters, the adjustment is divided into manual, electric, remote control and wind control, light control, rain control and many other ways for you to choose. Features: the main feature of this tent is cheap and practical. The sunshade cloth: generally equipped with ordinary canopy canvas, suitable for ordinary shops and small ordinary city.
Q:How to combine the paint and galvanized steel
No, as long as you choose the special galvanized steel pipe paint, mcGZ type is ok!
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:The steel structure material can do
Yes, if you are easy to do, you can
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:Square steel and C steel which is better?
Then use the square. Beautiful C steel, general color steel is not used. See you square high-rise, is firmly with the 100 by 100.
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
Wear zinc coating first, otherwise it is easy to form inclusion and other defects, and damage the strength of matrix.
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:The difference between square and square.
Square tube is kind of square body, many kinds of material can form a square body, most square to steel for the majority, after unpacking, smooth, curly, circular tube is formed by welding, pipe rolling into square tube and then cut into the desired length. Usually 50 bags each. Square pipe in the spot with large specifications in most, in the range of 10*10*0.8-1.5 to 500*500*10-25, square tube by use is divided into structural square tube, decorative square pipe, building square pipe, mechanical square tube, etc..Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process.
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,
