Mild steel is sometimes referred to as carbon steel or plain steel. Typically, it is stiff and strong. Carbon steels

do rust easily, but they can be easily painted or primed. They are cheap so they are the normal choice for most

fabrications. Mild Steel can be easily cut or drilled to meet your requests.

square bars are widely used for machine-made industry,chemical industry,spin,shipping industry, architecture,

food industry, housed.

Q:The steel structure material can do?
The steel can be used as structural materials to use, but not commonly used, are generally only used in the special requirements of the situation
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:How much is the thick wall hollow square 30*30
Square: solid, bar. Different from the square pipe, hollow, belong to the pipe. Steel (Steel): material of various shapes, sizes, and properties required by pressure processing for ingots, billets, or steels.
Q:4*4 steel welding frame tank do strong?
Electronic tube bracket fixed on a shelf, and then put the top shelf in the aquarium, pay attention to water, heat, can be a good solution, the lamp holder can buy ready-made, bought a switch, wires, plugs, insulating tape back to assemble their own good is.
Q:25-30mm drill pipe steel, to drill a lot, need what equipment
purposeApplicable to steel structure, shipbuilding, equipment manufacturing, equipment installation, bridge engineering, wind power generation, oil drilling platform, power construction, railway manufacturing and other fields.
Q:The difference between cold and hot galvanized steel hollow where
Cold rolling process is: the strip through the mold, pipeline bending forming, and then through the automatic welding, the welding joints, and then polished, galvanized, also called seamed tube.
Q:Reinforced concrete and steel stairs to do the stairs which is better
The rectangular steel tube is also not easy to makeThe stairs were made, and there was no concrete, and the stairs were steady and durable. Easy to vibrate and rust.
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:How to combine the paint and galvanized steel
You can spray paint directly. General zinc plating, basically do not need to paint, if galvanized can not resist the corrosive environment, you can use non galvanized just now, and then use the way to strengthen the anti-corrosion (primer + epoxy resin, or asphalt).
Q:Hot dip galvanized steel can be welded
Hot galvanized square tubes can be welded.Hot galvanized pipe, welding needs to be polished galvanized layer, thoroughly remove zinc coating and oil, dust and other debris, exposing the tube itself metal color, and then welding.Zinc melting point of 419.53 degrees Celsius, low melting point, Zinc Oxide Zinc Oxide formed layer of hot combustion in high temperature welding thousands of degrees Celsius in the combustion of white smoke barrier zinc combustion, influence the flow of the weld pool of liquid metal, destruction of welding arc stiffness, the porosity, slag, weld crack.
