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:What is the tensile force of the galvanized flat steel of 20*3?
According to "hot rolled flat steel size, shape, weight and allowable deviation", GB 704-88:Ordinary class allows upper deviation +0.3mm, lower deviation -0.5mm; higher allowed upper deviation +0.2mm, lower deviation -0.4mm, the upper deviation is not to think, do not exceed the next deviation is good.
Q:80 * 80 * 4 galvanized flat steel is what specifications?
Galvanized square is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; or the cold hollow steel well in advance of the re galvanized square by galvanizing processing of pipe.
Q:Lightning protection grounding, what is called three surface welding?
When lap welding is adopted, the welding length is as follows:1, galvanized steel bar is not less than its width of 2 times, three surface welding. When the width of flat steel is different, the length of lap should be wide. Before laying, the flat steel should be adjusted straight, simmer, bend not to die, straight line should not be obvious bending, and should stand upright.2, galvanized round steel welding length of 6 times its diameter, and should be double-sided welding (when the diameter is not the same, the length of overlap in diameter should prevail).3, galvanized round steel and galvanized flat steel connection, its length is round steel diameter of 6 times.4, galvanized flat steel and galvanized steel pipe welding, in order to connect reliable, in addition to contact in itBoth sides of the site shall be welded, and the flat steel itself shall be bent in an arc to be welded with the steel pipe.
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:Are galvanized flat steel and angle steel the same price?
This is not to say that depends on how you choose, simply said the product itself is good a bit different, if you choose the amount of zinc is not the same, the price will be different. If there is anything you need for this piece of steel, you can call on me. I am in Tianjin, Tangshan, a generation of steel business.
Q:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
The cable tray is divided into trough, tray type and ladder format, network structure, and is composed of a bracket, bracket and installation accessories etc.. The building bridge can be set up independently, can also be attached to all kinds of building (structure) of buildings and pipe support, should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance, etc., all parts are to be galvanized, installed in the building outside the open-air Bridge
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:How can copper cables and flat steel be welded together?
If it is filamentous, press press terminal (open type to cut tin). The terminal is pressed onto flat steel for corrosion protection. It is not allowed to be directly pressed to flat steel, so it must be brazed to flat steel by copper
Q:Building poles, outdoor flat steel, the deeper the buried depth, the better?
The construction of outdoor flat steel at normal negative 1.5m or so, there is design requirements. Nor does it mean that the deeper the better. The main function of the outdoor ground flat steel is that when the lightning resistance of the main body of the building is not up to the design requirements, the artificial outdoor triangular steel pipe pile shall be added to the outdoor earthing flat steel until the ohm value is qualified. Normally, the outdoor ground flat steel does not work.
Q:What is the thickness deviation of 40*4 galvanized flat steel?
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
