Q:Galvanized flat steel how much is one meter?
Formula of flat steel: width * thickness * 0.00785 (kg/m), zinc coating weight: 1.06Galvanized pipe formula: (outer diameter wall thickness) * wall thickness * 0.02466 * 1.06, DN25 galvanized pipe outer diameter 33.5, GB thickness 3.25, weight: 2.57kg/m, DN32, outer diameter 42.3, wall thickness 3.25, weight: 3.32kg/m. DN stands for nominal caliber.Angle formula (approximate): edge width * thickness * 0.015, 4# angle iron weight 2.422kg/m
Q:What is the difference between steel band and steel ring? Steel strip is flat steel, steel ring is made of steel
Q:How is three grade steel connected to ground flat steel?
Steel bars welded with flat bars should be of little size, 12mm bar, and if you are not sure, you can use a section of HRB335 over.
Q:How many years can hot dip galvanized flat steel be used?
Coastal areas usually refer to a region within a mile of the sea. The ocean atmosphere can spread deeper inland, especially on islands. The prevailing winds come from the ocean, and the climate is bad. If the wind is mixed with ocean fog, especially due to evaporation and accumulation of salt deposits, coupled with less rain and less frequent rain erosion, coastal conditions will be even more unfavourable. If there is any industrial pollution, there is more corrosive. Hot galvanized flat steel in such circumstances, usually 20 years or so.
Q:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
The cable tray is divided into trough, tray type and ladder format, network structure, and is composed of a bracket, bracket and installation accessories etc.. The building bridge can be set up independently, can also be attached to all kinds of building (structure) of buildings and pipe support, should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance, etc., all parts are to be galvanized, installed in the building outside the open-air Bridge
Q:The difference between galvanized flat steel 40*4 and galvanized flat steel 80*8 is the difference on the material list!
There are many kinds of flat steel, Q235A/B/C, mainly depends on the location of your specific requirements, what is needed?;
Q:50*4 hot dip galvanized flat steel can be used as grounding. How many square feet can be used instead of ground wire?
GB is not 50*4, but 4*40; International Electrotechnical union IEC is 3*25 can also, and if it is small houses, GB only 6mm diameter of it. It can be seen that the size of flat steel is mainly due to the consideration of mechanical strength and more than the consideration of electrical performance
Q:What is flat steel, please?
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
Q:The distinction between flat steel and steel strip
Blue is to heat the steel or directly immersed in concentrated oxidizing solution in the air, material protection technology of oxide film on the surface of thin produce, also known as black. The blue steel parts can be carried out in the molten salt of sodium nitrite and sodium nitrate, can also be carried out at high temperature above 500 DEG C hot air and superheated steam, the more common is heating sodium nitrite in concentrated caustic soda. Solution composition, reaction time and the temperature of Bluing depends on steel matrix composition. Bluing film composition is magnetic iron oxide, the thickness of 0.5 to 1.5 microns, the color and the material composition and process conditions, a dark gray, dark blue, etc.. Bluing film separate corrosion resistance is poor, but the oil wax or paint varnish, corrosion resistance and friction resistance are improved. Blue, the workpiece has little effect on the quality of size and finish. It is commonly used in precision instruments, optical instruments, tools, hardness blocks and so on.
Q:What is the thickness deviation of 40*4 galvanized flat steel?
Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings
