Product Description:

Production Flow of STEEL FLAT SS400

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


Tangshan  flat bar processing plant


Our factory was founded in 2008, has been formed steel processing, trade, distribution, haihe river transportation and information service in the integration of modern company, the headquarters is located in the national steel rich district of tangshan city, hebei province, the first big province, covers an area of 20 mu, is apart from the beijing-shenyang high-speed 0.5 kilometers tangshan north exit, the geographical position is superior, the traffic is convenient.

The company owns the most advanced domestic shear steel equipment, plasma cutting equipment, can according to customer demand for steel plate kaiping, slitting, crosscutting, shear and winding and other personalized processing services, enable customers to save steel cut expenses and losses, greatly reduce the production cost, improve production efficiency. Its main products are steel billet, steel strip, flange plate and web plate, flat steel, open the tablet, etc.

Products applied to the export of flat steel, steel structure, steel plate, cars, ships, cement, steel girder plate socket, machinery manufacturing, bridge template, and other industries. Processing width: 10 mm - 1250 mm, the thickness of 1.5 mm - 16 mm, the length can be due to the needs of customers, annual processing capacity of 100000 tons. Product quality in line with the GB/T 709-2006carbon structure and hot rolled steel plate and strip of low alloy structure" of the relevant requirements.

In the increasingly market competition, the company in good faith integrity, mutual benefit and win-win principle sincerely look forward to cooperating with you!

Q:Construction of electrical grounding steel flat buried anti-corrosion requirements, galvanized steel flat welding parts should be done anti-corrosion treatment, not welding parts are also doing anti-corrosion treatment?
Galvanized flat steel itself does not need additional corrosion protection.
Q:What is flat steel for?
Hot rolled flat steel is a general purpose rectangular cross section strip. The specifications are expressed in millimeters of thickness * width, flat steel can be finished steel, used for components, ladders, bridges and fences, etc.. Flat steel can also be used to weld rigid steel and billets and slabs of laminated sheets. (material: Q215, Q235), the implementation standard: GB704 - 1988 instead of GB704 - 83, this standard applies to the thickness of 3~60mm, width of 10~200mm, cross section of rectangular hot rolled flat steel for general use. Delivery status: flat steel delivered by straight line. Measurement: flat length and length of flat steel, according to the theoretical weight of delivery.
Q:What is the difference between flat steel and steel sheet material
It is a kind of flat steel, flat steel plate is mainly used for general structure, construction, general machinery parts; and the steel plate is including carbon steel, alloy steel, high performance steel structure, this kind of material is.
Q:Is medium plate steel flat?
Medium and heavy steel plate is mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc.. Can also be used to manufacture all kinds of containers, furnace shell and plate, bridge and vehicle static steel, low alloy steel plate, ship plate, boiler plate, pressure vessel steel plate, embossed steel plate, steel plate for automobile frames, tractor parts and some welding components etc.. Through the plate uses: widely used in the manufacture of various containers, furnace shell and plate, bridge and vehicle static steel, low alloy steel plate, bridge plate, boiler plate, steel plate, a pressure vessel steel plate, embossed steel plate, steel plate for automobile frames, tractor parts and some welding component application.
Q:What about the installation height of the socket and the height of the ground flat steel?
In accordance with the final use of functional considerations, it is not recommended to reduce the socket installation height. According to the actual use of functional requirements, the socket location can be changed to optimize to avoid the ground flat iron position? If it is not feasible, then reduce the height of ground flat iron.
Q:What does QB stand for in Q235B flat steel? What's the difference between Q235B and Q235A?
There are also some subtle differences between Q235A and Q235B:1, chemical composition: Q235A:C:0.14~0.22:Mn:0.30~0.65; S:0.050;2, mechanical properties: tensile test without distinction, impact test A do not do, Q235B I-beam, Q235B angle steel, Q235B channel steel, Q235BH steel, Q235B flat steel B do 20 degree impact test, V type impact power (longitudinal) J no less than 27.
Q:Where is the use of flat steel in electrical use?
The flat steel used in the project consists of two types: galvanized and non galvanized. Galvanized is mainly used in decorative materials and pipes, such as rings, hoop and so on;
Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
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
Q:The distinction between flat steel and steel strip
Cyanide is a chemical heat treatment, before the process is highly toxic, serious environmental pollution, the latest process can meet the requirements of environmental regulations, and if not necessary, the use of nitrogen treatment or carbonitriding better.
Q:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Connect the equipotential terminal box to the ground flat iron and cannot use plain flat steel. What level of ground steel must be used in AC electrical grounding standards, and must be hot-dip galvanized flat steel, the first is corrosion protection, and the second is long acting. Whether or not galvanized is always corroded, all national standards, industry standards, local standards are required to use hot-dip galvanized flat steel. And, depending on where it was buried, the size of flat steel was decided.
