Q:How to hollow square steel welding
Hollow square steel thin wall, should use special fixture precision counterparts, and retain the appropriate gap, in order to ensure the welding quality.
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:Round and square steel which is strong
Of course, the round steel is stronger. There was not because round steel is not convenient, a bar where rolling will affect the construction safety and progress. Log and wood with the same size and length to try to lift the increasing weight of the timber is certainly the first break. The cylinder is the strongest and most durable.
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:The difference between galvanized square and galvanized steel
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.
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
Generally it is installed, both ends of the welding pipe will be closed, if the internal tube can be in a closed state, the inner wall surface after a certain period of time, will form a passivation layer, no further corrosion, so long as the section strength enough, in the period of use should be safe.
Q:The difference between the steel chrome and paint
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 is sprayed directly, and thenGeneral steel can paint and painting the door company most paint steel, but you must ask whether to do heat treatment, because the paint that is backward spray drying
Q:How can we see is galvanized steel or wood
The galvanized pipe with square tubes is galvanized steel strip processing, forming, anti-corrosion time, there is no hot galvanizing time, hot galvanized is processedThe black tube. Galvanized in galvanized square tube factory. After 1000 degrees of high temperature, the general wall thickness is relatively thin, can not do hot-dip galvanizing.
Q:How to connect with steel purlin roof
1, if the structural part of the main steel structure is H steel or other profiles, that is, steel roof truss;2, if the structural part of the main steel structure is bolt ball or welded ball, that is the steel space truss, and steel space truss also belongs to the category of steel roof truss, but the steel grid is called more accurate;
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"
