Q:Round and square steel which is strong
The steel production and processing type of hot-rolled and cold drawn two. Hot rolled steel length of 5 ~ 250mm, 3 ~ 100mm length of cold drawn steel.According to the carbon content and the corresponding use, import and export of round steel can be divided into two categories: low carbon round bar and medium carbon. Low carbon raw materials mainly used for wire drawing, forging rivets, bolts and nuts and other metal products. Carbon steel and round steel commonly used to make mechanical parts.
Q:The steel structure material can do
The square can be built steel shed, small steel shed are built with square, purlin is divided into 98% major plant two 4*6 and 4*8 5*10 are not a pillar or beam with the tube, because not standard
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:Building with steel or steel plate?
Recommended use of channel ten, three meters span is not large, there will be no vibration problems! Do not use the bearing structure of square steel tube, the solid steel with the specifications of the cost is too high and the bending strength is hollow, not recommended.
Q:What is the cold drawn steel material? Why did it break?
This should be the problem of raw materials, raw materials are hot-rolled round steel or steel, raw material impurities, there will be extended by cold drawing fracture phenomenon. Materials for large steel mills are proposed.
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:The difference between the steel chrome and paint
General steel can paint and painting the door company most paint steel, but you must ask whether to do heat treatment, because the paint is paint backward Hongfang heating paint drying process.
Q:How to connect with steel purlin roof
The canopy is divided into two parts, one is the structure of part two is part of enclosure (that is, roofing materials, such as glass, aluminum plate, color plate etc.)
Q:Twist steel (twisting steel) there is no standard?
Because the steel plate for standard parts, CAD drawing without draw, only need to mark the type and size of the bearing flat steel lattice steel plate and the direction of the steel grid plate, the specific use of what types of bar, can be specified by the user, if the platform is too large, can be discharged from the layout of steel grid plate manufacturers, general row layout is free.
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.
