Usage/Applications of Q235 Steel Flat Bar

Widely used for construction, Machinery manufacturing, Iron tower steel structure, Shipbuilding; Steel grating, Staircase, Bridge, Viaduct, Railway spare parts, Boilers making etc.

 

Production Flow of Q235 Steel Flat Bar

The steel flat bar is made through three processes:

1.Feeding the material: Feeding the row material (the steel plate) to Slitting Line.

2.Slitting:The steel plate would be slitted into expected width by lengthways cutter.

3. Leveled and cutting: The plat bar would be ground into level by the grinder and then cut into required length.

 

Packaging & Delivery of Q235 Steel Flat Bar

Packaging Details: The Steel Flat Bars are packed in bundles and loaded in 20 feet/40 feet container, or shipped by bulk cargo ,also we can do as customer's requirements.

Delivery Details:30~45 days upon the receipt of buyer payment by T.T. or L/C.

 

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: 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: What makes stainless steel stainless?

A3: 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.

Q4: Can stainless steel rust?

A4: 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:Cold rolled flat steel standard. What is cold rolled flat steel?
Flat steel, width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:What's the difference between stainless steel flat bar 304 and 316
From the metallography point of view, because the stainless steel contains chromium, the surface forms a very thin chromium film, which separates from the oxygen penetrated by the steel.
Q:What is flat steel, please? What are the specifications of flat steel?
Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:Lightning protection grounding, what is called three surface welding?
The grounding position of the grounding body shall not be less than 3m; when the ground is embedded in the garbage or ash, it should be changed and compacted.The grounding body (line) shall be connected by welding, the welding seam should be full and adequate mechanical strength, no slag, undercut, crack, weld, welding defects such as pores, knocking the net after a drug paper, brush asphalt anticorrosive processing.
Q:What is the difference between 60X6 and 50X4 flat steel in grounding?
There are differences, mainly based on the local geological conditions, the purpose is to meet the requirements of grounding resistance.
Q:What does QB stand for in Q235B flat steel? What's the difference between Q235B and Q235A?
Low alloy steel Q235A and Q235B in A, B is the difference between the level of quality (total seems to be divided into four levels, you can check and confirm), the main difference is whether it is necessary to do the normal impact test, A does not need to do, need to do B.
Q:Why is it better to use round steel than that of flat steel in lightning protection?
Presumably, it's a discussion, not an answer.At the same length and with the same cross section,(1) the contact area between flat steel and earth is slightly larger.(2) flat steel is easier to bend than round steel, so it is more convenient to construct.(3) flat steel is easier to connect with bolt by connecting bolt.
Q:How is three grade steel connected to ground flat steel?
Welding method, the steel bar placed in flat iron plane, welding length is not less than 12 cm, welding is ok.
Q:80 * 80 * 4 galvanized flat steel is what specifications?
Galvanized square pipe.Specification: 80 * 80 * 4 is the dimension of galvanized square pipe. That is to say, the length and width of the inner diameter of the nozzle are 80mm, and the thickness of the tube wall is 4mm.
Q:What is the thickness deviation of 40*4 galvanized flat steel?
40*4 galvanized flat steel GB permitted negative deviation value is the thickness deviation value is 0.2mm, the deviation 0.4mm, the width deviation value is the upper deviation 0.5mm, lower deviation 1.0mm,
