Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
The weight is 0.395 kilograms / meter by the theory. Can be rolled, is not the foot, the largest is 7.5 diameter, the price depends on the place, and the price is different from place to place
Q:The two project is to use rebar or rebar?
It is recommended to use thread steel as far as possible, because the bonding force and holding force of the thread steel is better than that of the round steel, and it is generally known that the tensile pulling force of the round steel is relatively poor.
Q:What kind of steel pipe is round steel?
First of all, this is the two concept, round steel solid, hollow steel pipe; secondly, the round bar is divided into hot rolling, forging and cold drawn three. Generally seamless steel pipe can be divided into hot rolling (extrusion), cold rolling (pull), heat expansion of the basic types of steel pipe. Hope to be of help to you
Q:How can I connect channel steel and round steel?
First, the channel steel, channel cut, need to connect the length of the arc shaped gap, and then again and round steel arc surface welding, welding before the two kinds of materials to rust, and full welding.
Q:How to distinguish between cold plating and hot rolled round steel?
Cold galvanizing also called electro galvanized, is the use of the workpiece after electrolysis equipment except oil, after pickling solution into the composition of the zinc salt in the anode and connected electrolytic equipment; cathode zinc plate placed in the workpiece in the electrolysis equipment connected across the power supply is switched on, the current directional moves from the anode to the negative pole, will depositing a layer of zinc on the workpiece.
Q:What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
Cold drawn round steel (don't know, you mean can not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Refers to the galvanized flat steel width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of galvanized steel. Galvanized flat steel can be finished steel, also can be galvanized pipe blank and galvanized belt. With high strength, light structure: strong grid welding structure, so that it has high load, light structure, easy lifting and other features, beautiful appearance, durable.Galvanized flat steel can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.
Q:What is the difference between common wire and high-speed wire?
The universal wire and high speed wire are the wire rods (bars) of the rolling mechanism.High wire: refers to the use of high-speed torsion mill rolling wire rod. The rolling speed of 80-160 M / s, each weight (disc) in 1.8-2.5 tons, tolerance of high precision (up to 0.02mm), in the rolling process by adjusting the process parameters (especially in the cooling line) to ensure the different requirements for the product.
Q:What is galvanized round bar?
A cylindrical bar of iron or steel bar that crosses a layer of zinc on its surface.
Q:Why do I use the M25 round bar for the embedded bolt M24?
Because M25 round steel machine processing, the direct use of M24 round steel accuracy is not guaranteed
