Usage/Applications of HR Square Bar:

-The Square Bar is normally used as structure steel.

-Row material for other structure steel like steel angles, channels, I-beams, H-beams, etc…

 

Packaging & Delivery of HR Square Bar:

-Packing Detail: The products can be packed in bundles by steel wires.

-Marks: We make tag marks and color marks. The tag marks with white background and red company logo will be tied up to each bundle of the products. The information is usually including basic information of products and company and other information requested by customers. As for color marks, we will paint both ends of bundles to make sure that it will be more convenient for customers to distinguish them from other products.

-Delivery Detail: 30~45 working days after receive buyer’s T.T. or L/C.

 

Transportation:

-The products can be delivered by bulk vessel or by container. As for container, products with the length of 6m will be loaded in 20’ container, with 9m or 12m, in 40’ container.

-The maximum quantity of loading of container is 25 tons.

Q:4 x6 1.5 square meters thick, how much money
The steel prices generally calculated in tons. To see you say the steel is hot dip galvanized or black material. Hot galvanized general 4500/ tons, black wood generally in 3800/ tons. That is 4.5 yuan /kg and 3.8 yuan /kg. Forget it. You say this kind of steel is 2.355kg per meter. You can tell by your own price.
Q:The working principle of steel punching machine
Then tell you about the characteristics of mechanical punching machine1 mechanical punching machine uses lever principle, screw rod force, operation, saving labor, punching efficiency is high, punching once only 20-30 seconds;2 the main force head of the mechanical punching machine is made of super high strength alloy steel. It is light in weight and easy to carry;3 mechanical punching machine has the advantages of simple structure, convenient maintenance.
Q:How to connect with steel purlin roof
The steel wall frame generally refers to the glass curtain wall of the airport, or the windbreak wall of the coal yard. It is the wall structure, and the former two are the roof structure.
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
Wear zinc coating first, otherwise it is easy to form inclusion and other defects, and damage the strength of matrix.
Q:The difference between square and square.
Square tube is kind of square body, many kinds of material can form a square body, most square to steel for the majority, after unpacking, smooth, curly, circular tube is formed by welding, pipe rolling into square tube and then cut into the desired length. Usually 50 bags each. Square pipe in the spot with large specifications in most, in the range of 10*10*0.8-1.5 to 500*500*10-25, square tube by use is divided into structural square tube, decorative square pipe, building square pipe, mechanical square tube, etc..Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process.
Q:How to combine the paint and galvanized steel
You can spray paint directly. General zinc plating, basically do not need to paint, if galvanized can not resist the corrosive environment, you can use non galvanized just now, and then use the way to strengthen the anti-corrosion (primer + epoxy resin, or asphalt).
Q:Reinforced concrete and steel stairs to do the stairs which is better
Square is a square cross section of steel bars (square steel), not rectangular steel tube, can not do the stairs.
Q:How to fix the steel Aluminum Alloy
Aluminium and steel welding now has two processes, one is explosive welding, which relies on the tremendous pressure caused by the explosion to weld the steel and aluminum plate together. The other is a diffusion welding, at a certain temperature, the steel and aluminum contact surface diffusion, diffusion layer is very thin in the joint surface, this time is longer, and the high requirements, generally in the equipment of.Melting welding is not yet implemented, plus transition plate is now a method, not the true sense of the aluminum plate and steel welding, but the transition plate is produced by the above two methods.
Q:The difference between galvanized square and galvanized steel
The first dip galvanized pipe 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 formed hollow steel pipe prepared in advance will be galvanized by hot-dip galvanizing.
Q:It can be used as the steel electrical equipment grounding
The steel can be used as grounding of electrical equipment, but because of the steel and the earth contact surface is relatively small, the grounding efficiency is not high, generally do not use. The steel pipe, angle steel and flat steel and other materials, the ratio of the circumference and area, has a larger contact area with the earth, in the same material case, get smaller grounding resistance, or in the same requirements of the grounding resistance, supplies are more economical than small, square steel.
