FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:What does thread steel have to do with scrap steel?
There is a need to go through the processing of the construction units in the construction process of steel, for example, generally buy spiral steel to the standard 9 meters or 12 meters, the Jianshi needs 2.5 meters long 3.5 meters long and 1.7 meters long, 9 meters long steel eventually left a little cut small head these small head, or sold to a blacksmith shop, or you can only do what he can do, if he can do to the recycling of steel scrap processing.
Q:Why is thread steel thinner than crude?
Reduce the quality of the project, and the use of low carbon steel instead of rebar. For large engineering projects, often appear to "project inspector", to replace the steel rib steel "Choulianghuanzhu", reduce the construction cost. In the design, because the members allowed to provide "stirrup stress support", the main role is to keep the shape and location of longitudinal reinforcement, steel strapping has a smooth surface, accurate positioning, therefore, in addition to longitudinal reinforcement, licensing round steel stirrups. The longitudinal reinforcement must be made of rib steel.
Q:What grade of reinforcement is used for cast-in-place floorslab?
Cast-in-place floors are usually made of grade two steel.Cast-in-place is relative to the precast slab, casting is to place a good template on the site, the installation of steel reinforcement on the template, and then pouring concrete on the template, and then remove the template.
Q:How to calculate the theory of steel thread?
Calculation method: diameter * diameter *.00617*12 meters * one package of roots = a bundle of weight.
Q:What is thread steel for?
Three rebar is the new standard name for HRB400 steel, three steel for the old, as a kind of hot rolled ribbed bar. In construction, three - grade rebar is called the past.
Q:10 less than three rebar refers to the rebar?
A grade steel is round, without ribs, elongation is the advantage, of course, it also determines its strength is lower than grade three steel.
Q:What does "4E" mean on the rebar?
In addition, the extension rate of seismic reinforcement is not less than 9%, this figure is far higher than the standard of ordinary steel. And it is these technical indicators to enhance the strengthening of the seismic capacity of reinforced concrete, so that its tilt, deformation can be stabilized, not broken, reducing some casualties.
Q:What is the difference between rebar and round steel?
The difference between Jinzhong rebar and round bars: we can from the surface can be seen from the thread steel and round steel bar, we identify the next time don't let yourself do not understand the trouble, do not know how the difference.
Q:Is the theoretical weight of threaded steel and round steel the same?
The difference between such rebar and round bars with longitudinal ribs and transverse rib surface, usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution.
Q:25 screw steel, how many meters per meter?
25 thread steel one meter 3.86kg.Method of calculation: 0.00617 times the square of the diameter of the steel bar. The weight of each diameter of the steel bar (kg) can be calculated.Steel is known as hot rolled ribbed bar.
