Q:Why is a point of penetration of 2 square steel welding
With 2.5 of the electrode try, I solder 1 will do, hand gestures as soon as possible, it is not so easy to point out the hole, if the conditions can choose carbon dioxide protection welding, but the cost of welding should be high
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:Building height is 5m, the main dry hanging stone square spacing value should be how much better?
Say so much, directly tell you, if it is with square steel (main keel), that spacing in 1--1.2 meters is absolutely no problem, the standard is not allowed more than 1.2 meters, but the actual construction exceeds the situation or some. If there is no special circumstances (such as from the wall out more than 300mm or), then no problem, rest assured!!!
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 steel structure material can do?
First of all, will cause the waste of steel using square large section case, increase the weight of the structure, which is contrary to the steel structure of light weight advantages, small cross section from the processing, production process, the use of steel will be more, in addition to the special requirements, do not recommend the use of square steel.
Q:Hot dip galvanized steel can be welded
Hot dip galvanized steel can be welded. The main methods of welding are as follows:1. manual arc welding. Remove the welding seam and the nearby zinc coating before welding. The welding rod can choose J421/J422/J423 and E5001/E5003 welding rod according to different requirements;2. gas metal arc welding. CO2 gas shielded welding can be used.3. argon arc welding.4. resistance welding.
Q:How to fix the steel Aluminum Alloy
There are generally two practicesFirst, from the hidden frame curtain wall joints connecting bracket out glue;Two. Stick with structural adhesive;Practice is recommended.
Q:The difference between the steel chrome and paint
Room heating drying paint process. The utility model has the advantages of bright color, strong visual impact, good surface finish, easy cleaning, moisture resistance and good fire prevention performance. And spray paint isJust spray it directly and let him do it naturally. This is called spray painting. How to identify paint or paint it, let us introduce.
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 can we see is galvanized steel or wood
The first dip galvanized pipe is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency. Or the cold formed hollow steel pipe prepared in advance will be galvanized by hot-dip galvanizing.
