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: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:Galvanized flat steel how much is one meter?
Formula of flat steel: width * thickness * 0.00785 (kg/m), zinc coating weight: 1.06Galvanized pipe formula: (outer diameter wall thickness) * wall thickness * 0.02466 * 1.06, DN25 galvanized pipe outer diameter 33.5, GB thickness 3.25, weight: 2.57kg/m, DN32, outer diameter 42.3, wall thickness 3.25, weight: 3.32kg/m. DN stands for nominal caliber.Angle formula (approximate): edge width * thickness * 0.015, 4# angle iron weight 2.422kg/m
Q:Is there a requirement for the ground resistance of the field motor? Is it good to use ground flat steel or ground wire?
The enclosure is grounded and the ground wire is the same, and the ground wire requirement is no more than 4 ohms. Generally, the motor shell can be connected to zero. There is no need to ground. In the power system, earthing and zeroing can not be mixed.
Q:The technological process of flat steel
The production process can be summarized as: pre leveling, finishing, straightening and leveling. Flat /a/b 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. 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. Flat steel is divided into two kinds according to its shape: flat spring, flat steel and single side double slot spring flat steel. Hot rolled spring flat steel is mainly used in the manufacture of automobiles, tractors, railway transportation and other mechanical leaf springs.
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: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:Why do some buildings need a steel bar around the top?
Lead line of roof lightning belt. To be exact, galvanized steel or galvanized round steel should be used.Galvanized round bar and galvanized flat steel are of different shapes and different uses.
Q:What line is the LEB line, please? Is it wire or flat steel or galvanized round bar?
General requirements of the building's outdoor metal doors and windows, equipment shell, distribution box, etc., are required to do a second potential connection,It has not seen the specific technical requirements, we can use the past construction experience, building floor steel ring, Liang Gangjin, reinforced connecting line, equipment shell available 6 mm galvanized welded steel garden.
Q:-40x4 hot galvanized flat steel, a water 1m, what do you mean?
Water is to protect the wall foundation using cement mortar width not less than 600 of a circle along the walls of the cement ground, if the main part of the project before the electrical engineering, auxiliary grounding length less than in bulk water, auxiliary grounding, ditching to destroy the water, so that the design requirements of 1 meters water is conducive to the construction of welding, may be more than one meter in order to facilitate their work.
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.
