Product Description:

1. Structure of Steel Flat Bar Hot Rolled Retangular Section Description:

Steel flat bar hot rolled retangular section is a beam with an I-shaped cross-section. The horizontal elements of the "I" are known as flanges, while the vertical element is termed the "web". Steel flat bar hot rolled retangular section is usually made of structural steel and is used in construction and civil engineering. The steel flat bar hot rolled retangular section resists shear forces, while the flanges resist most of the bending moment experienced by the beam. Steel flat bar hot rolled retangular section theory shows that the I-shaped section is a very efficient form for carrying both bending and shears loads in the plane of the web.

 

2. Main Features of Steel Flat Bar Hot Rolled Retangular Section:

• Grade: Q235

• Type: Mild carbon steel

• Deflection: The stiffness of the I-beam will be chosen to minimize deformation

• Vibration: The stiffness and mass are chosen to prevent unacceptable vibrations, particularly in settings sensitive to vibrations, such as offices and libraries.

• Local yield: Caused by concentrated loads, such as at the beam's point of support.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

①Is this product same as W beam?

In the United States, the most commonly mentioned I-beam is the wide-flange (W) shape. These beams have flanges in which the planes are nearly parallel. Other I-beams include American Standard (designated S) shapes, in which flange surfaces are not parallel, and H-piles (designated HP), which are typically used as pile foundations. Wide-flange shapes are available in grade ASTM A992,[4] which has generally replaced the older ASTM grades A572 and A36.

②How to inspect the quality?

We have a professional inspection group which belongs to our company. We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

③Is there any advantage about this kind of product?

Steel I beam bar IPE has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred.

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 steel itself anti-corrosion, if there is no welding parts, then no longer do anti-corrosion treatment
Q:How many years can hot dip galvanized flat steel be used?
Industrial areas are heavy industries, causing air pollution in the region. Pollution may be caused by fuel gas, such as sulfur and nitrogen oxides, or other gases released by chemical plants or processing plants. Particles suspended in the air, such as dust produced in the process of steel production or deposition of iron oxides, also increase corrosion. In such an environment, life expectancy is about 20-30 years.
Q:What is the use of slitting flat steel?
Flat cut flat steel, also called fine shearing flat steel strip, can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.
Q:How to determine the application direction of steel grid plate
This order must be strict and clear. The steel grid plate in the length direction (flat length direction) on at both ends of a supporting beam, i.e. use or the use of slot, and ends in the width direction can not need support. Because the bearing capacity of steel plate mainly from the flat direction. For example drain cover
Q:Does the cable trench need grounding?
Cable trench grounding practices: ground pile using hot galvanized steel angle (50X5X2500), every 20 meters to hit a root. The pile top is 0.6 meters away from the ground, and the ground wire is made of galvanized steel flat bar (40X4). Cable grounding wire and cable groove on both sides of the main frame by welding, every 20 meters will ground wire leads and grounding pile welding, while the grounding cable trench on both sides of the ditch bottom connection, grounding wire used for 10 hot dip galvanized steel. All grounding devices need to be welded firmly at the joint, and the welding place is treated with asphalt.
Q:The minus sign in front of what 40 galvanized flat steel
Also called hot galvanized and hot dip galvanizing: 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)?
GB50169-2006 in the 3.4.2 stipulates that the grounding body (line) shall be welded by lap welding, and its lap length shall comply with the following requirements:1. flat steel is 2 times its width (and welded with at least 3 edges);2. round steel is 6 times its diameter;3. round steel and flat steel connection, its length is round steel diameter of 6 times;
Q:What is the difference between flat steel and steel strip?
It belongs to the conventional flat stainless steel series, steel to stainless steel sheet series, steel is cold rolled sheet, and a flat surface of hot rolled and cold rolled surface, flat iron is a common type of steel does not contain nickel, but sometimes some customers habitually called stainless steel flat steel flat iron.
Q:Earthing flat steel, width, overlap face, bolt, big country net
Usually 4 x 40 flat steel, you definitely won't use 6mm screw, but I use two 8mm screws to connect the strength of not less than 12mm of A.
Q:What are the standards for the use of galvanized steel angles and flat steel for grounding?
(1) grounding wire is generally made of 40mm * 4mm galvanized flat steel.(2) galvanized steel or angle steel for earthing body. The diameter of the steel pipe is 50mm, the wall thickness of the pipe is not less than 3.5mm, and the length is 2 to 3m. Angle iron shall be 50mm * 50mm * 5mm.
