- Inquire about price/MOQ

Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The same specification galvanized round steel, more than a round galvanized process, so galvanized round bar price = round bar cost + zinc + processing fee + three costs + wear and tear.
Q:Can steel bars be replaced by large screws in the concrete floor?
Tensile strength, extensibility, yield point! The same thread can be used instead!Of course, the number of roots must also be the same ~ only specifications vary!
Q:What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
The main differences are in mechanical properties. I don't know very well how to make round steel, I can't compare it. Forged round steel is expected to be used in the processing of some special performance requirements.
Q:Round bars and ribbed stirrups are much better
Hot rolled ribbed steel bar with high strength, suitable for large component high-rise buildings under gravity loads, but also because of its surface shape can provide grip and end without hook, the corresponding anchorage length is short, the material.
Q:What is the mechanical properties of No. 40 round bar?
40# stands for steel grades, round bars for steel profiles, mechanical properties for steels, tensile strength, yield point, (cattle / mm, 2) elongation, shrinkage (%), impact energy, Ak (coke), state, hardness, HB<
Q:What kind of nuts do you need for round 20 rounds?
The nut is connected to mechanical equipment parts, through the inside of the thread, the same specifications of nuts and bolts to connect together, such as M4-P0.7 and M4-P0.7 only bolt nut series connection (nut, M4 nut diameter is about 4mm, 0.7 fingers between the two thread distance of 0.7mm); US made products as well, such as screw nut only with the 1/4-20 1/4-20's collocation (1/4 refers to the nut inner diameter is about 0.25 inches, 20 inches each, 20 teeth).Self locking nut, lock nut, locking nut, four claw nut, the nut is screwed into the nut, screw rod nut insurance connecting nut cap nut six self-locking angle of anchor bolt with nut, six special angle crown thin nut eyenut.
Q:Which is stronger, steel pipe or round steel? Which is good at bending?
The strength of the steel pipe is slightly lower, but its weight is light, so as long as the wall thickness is reasonable, the experienced designer uses steel pipe instead of round steel.Like me, that's it
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Generally, the lightning protection devices of buildings are divided into two major categories: external lightning protection devices and internal lightning protection devices. The external lightning protection device consists of a lightning receiver, a lead off line and a grounding device, namely the traditional lightning protection device. Internal lightning protection device is mainly used to reduce the lightning current inside the building and electromagnetic effects, such as the use of electromagnetic shielding, equipotential connection and installation of surge protection device (SPD) and other measures to prevent the harm caused by lightning electromagnetic pulse.
Q:1, three, two, steel, wire rod, round steel what is the difference?
Wire is a wire, usually refers to the use of "high speed non-twist wire rod rolling mill, ordinary common low carbon steel, hot-rolled wire torsion free cooling (ZBH4403-88) and the high quality carbon steel, hot-rolled wire rod without torsion cold control (ZBH44002-88).
Q:Lightning protection earthing zinc plating flat iron and round steel welding method, need to flat iron wrapped in round steel outside welding?
Don't need, but the welding seam area not less than round or flat between the relatively small cross section, the weld to coated with anticorrosive paint. Generally speaking, the grounding part does not use steel, galvanized L type flat iron good effect (copper strip and galvanized L type flat iron is not much, just life is long, but the cost is much higher), round only used as grid wiring.
