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: Can stainless steel rust?

A2: 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.

Q3: What is the normal tolerance of Hot Rolled Mild Steel Angle Beams for Structures and for Buildings?

A3: Normally 3%-5%, but we can also produce the goods according to the customers' requests.

Q:Are steel bars used more in high-rise buildings or steel?
To see what kind of structure, frame structure, screw steel is much more used, such as beam column, main reinforcement, partial stirrups, plate reinforcement.
Q:Can the end of the steel bar be inserted by the steel bar?
Chemical method of planting steel refers to the concrete, walls, rock and other materials on the drilling, and then injected into high-strength steel planting glue (Note: high-strength construction bar planting glue is roughly divided into injection type planting glue and barrel type steel planting glue two). Then insert the steel bar or section bar, glue and solidify the steel bar and the base material bond as an integral whole, it is a kind of construction technology that is more commonly used in reinforcing and reinforcing industry.
Q:32 of the rebar is one meter multiple
Weight per metre (Kg) = diameter of reinforcing bar (mm) * diameter of steel bar (mm) * 0.00617=32*32*0.00617=6.318
Q:In the concrete floor, how big can the steel bar be replaced by the big screw steel? How to convert?
In theory, how big a round steel will have to replace the large thread steel, and if it is cast, then still better to use thread steel, screw steel tensile resistance than round steel by strong
Q:Can the thread steel of the steel platform of the fixed unloading platform not work?
Steel bars on a fixed discharge platform must not be threaded. HPB grade reinforcement shall be used.
Q:How to judge the quality of thread steel?
Sampling sample. Do tensile, bending, and impact tests.
Q:What's the difference between rebar and thread steel?
In construction, round bars and rebar are popular terms for different kinds of steel. There are five main differences between them:1. different shapes. The outer surface of the round steel is smooth; the outer surface of the spiral steel has a spiral rib.2. different production standards. In the current standard, round bar that HPB235 grade steel, and its production standards are "hot-rolled smooth steel reinforced concrete" (GB13013); rebar generally refers to HRB335 and HRB400 grade steel, its production standard is "the reinforcement of concrete hot rolled ribbed bar" (GB1499).
Q:The effect of adding alum on thread steel
Vanadium has many excellent physical and chemical properties, so vanadium has a wide range of uses. Most of the initial vanadium was applied to steel. By refining the microstructure and grain of steel, the grain coarsening temperature was increased, thus increasing the strength, toughness and wear resistance of steel. Later, people gradually discovered the outstanding improvement of vanadium in titanium alloys, and applied it to the aerospace field, which made the aerospace industry made a breakthrough progress. With the rapid development of science and technology, the demand for new materials is increasing. Vanadium is used more and more widely in the field of non iron and steel. Its range includes aerospace, chemistry, batteries, pigments, glass, optics, medicine and many other fields.
Q:What are the main uses of threaded steel?
The main use of rebar is to use beams and columns of important structures as well as bridges. The upper rib is stronger than the round steel when combined with concrete pouring!
Q:Why is round bar more expensive than thread steel?
Threaded steel should be used in the construction field, there are generally two, three grade steel, grade HRB335, HRB400 also has four grades, HRB500 thread steel.
