Q:Glass partition, square box outsourcing 1mm thick stainless steel, glass middle is how to set the quota
In this case, a metal frame must be used to hold the glass and then bolt it into the wall!
Q:How to connect with steel purlin roof
The steel wall frame generally refers to the glass curtain wall of the airport, or the windbreak wall of the coal yard. It is the wall structure, and the former two are the roof structure.
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:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
1 current 60-80, air flow 0, 5With 2 plates and square steel welding and 1 identical, square and square steel welding current is available in 120, with stronger welding flow unchanged.30, 2 of the plate welded iron angle iron, it is difficult to weld, the plate is too thin.4, black needle and gun mouth flat, go in a little can also.5 general gas stations are filled with large bottles of change. 13 presses per bottle. 8L only do the spare, easy to carry, only do the skeleton and winding, spot welding, sealing up can do 40 to 50.7 welding galvanized sheet iron with a lot of trouble. Try it and you'll see. The iron steel welding line, is not strong.
Q:You need to light steel keel wall square steel
Light steel keel, plasterboard partitionLightweight steel keel wall materials are 50, 75, 100, 150 and so on. The wall can be filled with insulating materials - insulation materials (such as rock wool board, rock wool blanket, foam board), can play a very good insulation effect.
Q:How the steel columns and I-beam steel structure connection?
The square column is usually connected with a connecting plate, and the upper beam is arranged on the connecting plate and is fixed by an electric welding or a bolt.
Q:What is the hot dip galvanized steel, production process?
The steel piece after being cleaned is dipped into the molten zinc liquid at about 445 DEG C so that the zinc coating is adhered on the surface of the steel member so as to prevent corrosion. Hot galvanizing process: finished acid washing - plating bath - drying - hanging - cooling - passivation - Cleaning - polishing - Inspection - finished products
Q:How much is the thick wall hollow square 30*30
Steel is an important material for national construction and the realization of the four modernization indispensable, wide application, wide variety, according to the different steel profile is generally divided into sections and plates, pipes and metal products four categories, in order to facilitate the organization of steel production, supply and improve order management, and divided into heavy rail, light rail, large steel, and steel, small steel, steel cold-formed steel, high-quality steel, wire rod, steel plate, steel sheet, electrical silicon steel sheet, strip steel, seamless steel pipe, welded steel pipe, steel, metal products and other varieties.
Q:Hot dip galvanized steel can be welded
The hot dip galvanized steel pipe has excellent atmospheric corrosion resistance, and it can easily form a protective film on the surface at room temperature, which has good corrosion resistance.When the weld is cooled, coat the weld with silver paint to avoid rusting at the weld.
Q:As for steel structure steel, how appropriate
Column: 200*200*8 rectangular tube as column, beam (main beam) is 300*300*12, secondary beam is 150*150*8@1500 evenly distributed. Roof beam 150*150*8 herringbone roof truss.
