Q:How to hollow square steel welding
Because the hollow steel thin wall, the use of electric welding should be used for small diameter with 2.5 electrodes, current should not be too large, can be around 100.
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 water was poured into the square on how to prevent rust after treatment
The steel should try to avoid the rain, if you have been caught in the rain, according to the properties of the steel is not the method to wipe, such as high hardness steel wire brush, cloth, cotton and other materials of low hardness.
Q:Are square steel, rectangular tube and angle steel shaped or light steel?
Belongs to the type steel, also belongs to the light steel. The question you ask is equivalent to whether apples, grapes, or bananas belong to fruit or food
Q:It can be used as the steel electrical equipment grounding
In the electrical grounding body, generally use the steel pipe, angle steel, flat steel, round steel and other steel specially made grounding. The artificial grounding body and the ground wire form a grounding device, so that various earthing of the electrical equipment is connected with the ground through a grounding device. The artificial earthing body has two kinds of vertical embedment and horizontal embedment. The vertical buried pipe, angle steel, round steel grounding body, and have sufficient mechanical strength; ground level buried body with round steel, flat steel, common type, with several ring and radiation type. It is better to use galvanized steel when laying artificial earth in strongly corrosive soil. The steel used in the earth body shall be in accordance with the requirements of thermal stability and uniform pressure.
Q:The difference between galvanized square and galvanized steel
Hello, SECC 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; galvanized square cold-formed steel hollow or well in advance of the hot dip galvanized after processed tube.Galvanized square steel: first the steel bar is solid. Different from the square pipe, hollow, belong to the pipe. The steel surface is galvanized, galvanized steel.
Q:What is the use of square steel keel or welding steel canopy
What material is most suitable for the construction of the canopySelect the canopy material, is the most important part of the awning construction, suitable materials, not only save money, and effort, but also worry. The awning material is usually divided into: "sunshine in canopy, canvas canopy, laminated glass awning, canopy tile".
Q:Building with steel or steel plate?
It is recommended to use channel No. 12, and the span of three meters is not big, so the problem of vibration will not occur! Square steel tubes are not recommended for load-bearing structures. I'm from the steel installation department.It is suggested that the upper channel, the red plate, and the wood. It's more comfortable to use.
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.
