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.

Q:How to connect the base of the tower crane and the flat steel? How can it be welded and connected?
How to connect the base of the tower crane and the flat steel?:It can be punched on a flat iron and connected by screws and multiple copper wires
Q:The grounding electrode 50 angle steel and the ground wire 50, the flat steel lap welding, according to the specification 169 needs the flat steel to be late 90 degrees, bends close to the angle steel side, the overlap width is 4 times (200mm)?
Flat steel and steel, flat steel and angle steel, in order to reliable connection, should be in addition to the contact regions on both sides of the welding, and welding with arc steel should be bent into (or rectangular) clips or directly from the strip itself curved (or rectangular) and steel (or steel) welding.
Q:Friction coefficient of steel pipe and flat steel on roller table!
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt 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. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
Q:What's the meaning of ground flat steel -60*8 hot dip galvanizing?
Hot dip galvanized (galvanizing) also called hot dip galvanized and hot dip galvanizing: is an effective way of metal corrosion, mainly used for metal structure on the facilities of the industry. The steel piece after being cleaned is dipped into the molten zinc liquid at about 500 DEG C so that the zinc coating is adhered on the surface of the steel member so as to prevent corrosion.
Q:How many years can hot dip galvanized flat steel be used?
Coastal areas usually refer to a region within a mile of the sea. The ocean atmosphere can spread deeper inland, especially on islands. The prevailing winds come from the ocean, and the climate is bad. If the wind is mixed with ocean fog, especially due to evaporation and accumulation of salt deposits, coupled with less rain and less frequent rain erosion, coastal conditions will be even more unfavourable. If there is any industrial pollution, there is more corrosive. Hot galvanized flat steel in such circumstances, usually 20 years or so.
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:Where is the use of flat steel in electrical use?
Flat steel is used for earthing and galvanized. Mainly used for grounding and grounding to objects (such as the need to join line equipment ground and grounding, lightning arrester and grounding) and grounding connection between the neutral line and the center point, connected with the neutral line
Q:Where can I buy ground level bending machine?
Galvanized flat steel and galvanized steel (or steel) for welding, reliable connection, should be in addition to the contact regions on both sides of the weld, should also direct the flat curved (or rectangular) and steel (or steel) and steel pipe welding, when welding on the steel pipe wrapped around the welding length 2 times less than the width of flat steel.
Q:What is flat steel, please?
The contract and other documents will be of stainless steel edge width, edge thick size fill in complete, and main process other matters: Hot + cold drawing + pickling, polishing, annealing, solid solution, stainless steel according to the different needs of structure composed of a variety of stress components, also can make connections between components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container rack and warehouse shelves.
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.
