A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q4: What makes stainless steel stainless?

A4: 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.

Q:How can a round steel weld on a flat steel plate be flat and qualified?
On both sides of the steel and welded steel plate, each side of the weld length of 5 times the diameter of reinforcement, welding seam should be welded into a convex arc that is.
Q:What is round steel?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed as millimeters in diameter. For example, "50" means a round steel with a diameter of 50 millimetersRound bar is divided into three kinds of hot rolling, forging and cold drawing. The specification of hot rolled round bar is 5.5-250 millimeters. Among them, 5.5-25 rounds of small round bars are mostly supplied by straight strips. They are commonly used as reinforcing bars, bolts and various mechanical parts;
Q:How to distinguish between cold plating and hot rolled round steel?
Cold galvanized profiles: cold galvanized is electroplating, is absorbed by the charge, the charge is concentrated in the edge, angle and other cutting-edge, so the inner surface and recess will not be plated phenomenon. The surface of the steel is relatively smooth and bright.Hot dip galvanized bar: hot dip galvanizing is to remove oil, pickling, dipping and drying into the molten zinc bath for a certain period of time. The appearance was galvanized slightly rough, silvery white appearance, easy to produce and process water a few drops of tumor, especially in the one end of the workpiece is more obvious.Galvanized quality certificate must be provided for hot-dip galvanized sections.
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:45# what are the main rounds for?
45# round bars are divided into three kinds: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of them: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
Q:What is the difference between a circle and round steel continuous casting
Round steel drawn from a continuous casting is called a round billet; the rolled round steel is called a bar.
Q:Excuse me and steel disc round what is the difference?
Wire rod refers to the hot-rolled steel bar of 5-22mm diameter or the special-shaped steel of this section. As a result of wire rod delivery, it is also known as wire rod.
Q:Special steel bar steel products used to do what
Carbon tool steel is high carbon steel basically contains alloy elements, the carbon content in the range of 0.65% ~ 1.35%, the production of low cost, easy to obtain raw materials, good machinability, after treatment can obtain high hardness and high wear resistance, so it is widely used in steel, used to manufacture all kinds of cutting tools, mold, measuring.
Q:The problem of dowel bars on concrete pavements?
The dowel bar is arranged according to the transverse contraction joint and expansion joint set, meaning that a transverse contraction joint and expansion joint place dowels, are not plate must be set. In general, each 200m set a expansion joint, or other road intersection, and bridge connecting point must be set up.
Q:What's the difference between bearing steel and round steel?
Bearing steel refers to the steel used to make bearings. Round steel is generally referred to as round bar steel. One refers to the material, and the other refers to the profiles. Such as bearings, needle roller raw material is round steel, but also bearing steel.
