Q:100*100*2.5 square with 20 square meters of housing security light steel structure:
Sun room in the South or the north, need to reserve the burden of snow is not the same.
Q:The working principle of steel punching machine
Imported PLC control system, industrial color LCD touch screen AC servo motor and driver, imported linear guide rail and fine ball screw, universal ball or brush board, work table and other high-end configuration;
Q:The joiner board is fixed on the square on how
Self tapping nail is generally refers to the thread of the tooth is self tapping, so that the role of self drilling, do not need to use the nut together. The screw head has a lot of classification, there are six outer corners of the head, pan head, with countersunk head, internal angle of six head. An umbrella head, padded head, etc. The tail is usually pointed. Self tapping.
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:The moment 2mm thick galvanized square steel tube using what welding methods
If the mind zinc burning for the tube effect, can use silicon bronze gas welding, Odin 204Si, with special reference "Wiodin 204Si bronze wire in welding of galvanized plate"
Q:Twist steel (twisting steel) there is no standard?
Lattice steel plate steel bar is also called twist, the steel twisted shape, so only when the square size annotation annotation, common general specifications for 8*8mm, 6*6mm, 5*5mm, in the standard steel plate, the bar is defined as fixed on the bearing flat steel, round steel, square steel twisted or flat, that is say, don't necessarily use twisted steel (steel twist) but hot dip galvanized steel grid plate used in the steel industry used torsion, stainless steel using round steel, and make use of flat bar made of steel plate. We called steel grid plate or pressure locking steel plate, steel plate of GB also do this cross sectional area:: twisted steel, round steel bar with flat steel, its cross-sectional area of not less than 20 mm.
Q:Glass partition, square box outsourcing 1mm thick stainless steel, glass middle is how to set the quota
Can consider to increase the insurance factor, the edge of the glass with epoxy resin and solid wall such as granite wall adhesion (which went to the production of glass curtain wall) will not allow the use of styrofoam! Because of adhesive power, shear resistance and so on are poor.
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:How much is the thick wall hollow square 30*30
Hollow square 30*30 wall thickness is 5mm.
