Q1: Why buy Materials & Equipment from

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

Q2: How do we guarantee the quality of our products?

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:Excuse me, the difference between round steel, screw steel, steel, plate material, steel wire, hope professional answer?
The 2 plate and steel hot rolled steel plate, it is hard to know, the difference between rebar and rod easily screwed, clear, thread steel by chemical factory is a very deep rib.
Q:Why is it better to use round steel than flat steel in lightning protection?
Of course, the contact area of flat steel and soil are large, relatively scattered large flow area, the construction is more convenient, in terms of price, we are willing to use flat, as for the problem of anti-corrosion, anti-corrosion paint, zinc can be taken, you know, the thickness of galvanized steel pipe is generally not flat, so true to see the term for the use of galvanized flat steel is not bad.
Q:The difference between galvanized round bar and galvanized flat steel?
Round steel (grade 1 steel) belongs to ordinary low carbon steel with low strength. However, the plasticity of the round bar is stronger, that is, the round steel has a larger deformation before it is pulled off.It has been widely used in the fields of hardware, construction, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, space, etc.. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.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.
Q:Grade 1 steel is round steel, grade two steel is ribbed thread steel. Are the weight of the two units the same?
Grade two steel is ribbed steel, but the average diameter is calculated. The chemical composition of grade steel and grade two steel is different, but the density of them is the same. Therefore, the unit weight of grade 1 steel and grade two steel is the same.
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:Difference between cold drawn round steel and round steel
Cold formed steel allows partial buckling of the cross section, thus taking full advantage of the post buckling capacity of the member, while the hot-rolled section does not allow partial buckling of the cross section.
Q:What are the differences between hot rolled stainless steel rounds and cold drawn round ones?
The main differences are in mechanical properties. Forged round steel is used in the processing of some special performance requirements. Round steel three processing methods are more common, should be very wide surface.
Q:Which is hard, round steel or screw steel?
If the diameter is the same, of course, the rebar is of great hardness.Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.
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:What is the tensile strength of Q235 round steel?
Level 1, surface shape, light circle, strength code R235, grade Q235, carbon content 0.14%-0.22%. Silicon content 0.12%-0.30%. Manganese content 0.30%-0.65%, phosphorus content is equal to less than 0.045%, sulfur content is less than or equal to 0.050%,
