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:How to make the steel arc
If reinforced by 1. fold 2. arc bending machine flame cutting machine 4. fold 3. baking arc building arc roll can be solid steel grip bending machine processing.
Q:Reinforced concrete and steel stairs to do the stairs which is better
Square is a square cross section of steel bars (square steel), not rectangular steel tube, can not do the stairs.
Q:How to ensure the steel paint off paint
Authentic traditional painting techniques include the following three steps:The 1. is to use a paintbrush dipped in paint: paint bucket, spread on the coated surface.2., open oil: that is, the shop on the surface of the paint immediately pull open, to promote the film extended evenly.3. paint: paint brushes gently spread evenly with solid particles and straighten out the paint, the paint off and excess paint.You paint square, from top to bottom, by plane, according to my above paint method can ensure the uniform film.In addition, you must use special metal paint finishing of polyester type steel, to ensure no paint brush.
Q:The difference between galvanized square and galvanized steel
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: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:The difference between square and square.
Square tube is kind of square body, many kinds of material can form a square body, most square to steel for the majority, after unpacking, smooth, curly, circular tube is formed by welding, pipe rolling into square tube and then cut into the desired length. Usually 50 bags each. Square pipe in the spot with large specifications in most, in the range of 10*10*0.8-1.5 to 500*500*10-25, square tube by use is divided into structural square tube, decorative square pipe, building square pipe, mechanical square tube, etc..Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process.
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: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:4*4 steel welding frame tank do strong?
Or more strong legs 4 legs is not easy to findAdd a circle support at the bottom of the cylinder, top two, it is better to get a board, more stable table
