Usage/Applications of Hot-rolled Square Steel Bar:

-The Square Steel is normally used as structure steel.

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

-Row material for steel pipes.

Packaging & Delivery of Hot-rolled Square Steel Bar:

-Packing Detail:

1, The products can be packed in bundles by steel wires.

2, The weight of each bundle no exceed normally 3 tons.

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

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

Payment:

-Invoicing on theoretical weight or actual weight as customer’s request.

-FOB, CFR or CIF.

-Regular terms of payment:

1, 30% payment in advance, the remaining balance (70% payment) against the copy of B/L.

2, 30% payment in advance, the remaining balance (70% L/C) against the copy of B/L.

Q:Round and square steel which is strong
Of course, the round steel is stronger. There was not because round steel is not convenient, a bar where rolling will affect the construction safety and progress. Log and wood with the same size and length to try to lift the increasing weight of the timber is certainly the first break. The cylinder is the strongest and most durable.
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 steel and wood preservative in the flower is how to connect
Through an angle, angle steel and steel welding, anticorrosive wood frame strip and steel bolted.
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:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
Argon arc welding is a kind of welding technology using argon gas as protective gas. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding welding technology to achieve a metallurgical combination, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
Q:How to fix the steel Aluminum Alloy
With self tapping screws, that is, with drill screws, building materials market can buy. Electric screwdriver, you can put the wood board through self tapping screws into the steel. But attention should be paid to buy the self tapping screw length, short patch does not live too long into the square, too much is not good.
Q:The difference between galvanized square and galvanized steel
There is a difference in the quality of classification and can be processed into cold and hot dip galvanized pipe, galvanized pipe, galvanized pipe and galvanized belt can not be made, because of its wall thickness is thin, so the price will take the price dip galvanized pipe is much higher than galvanized pipe.
Q:The difference between cold and hot galvanized steel hollow where
Cold rolling process is: the strip through the mold, pipeline bending forming, and then through the automatic welding, the welding joints, and then polished, galvanized, also called seamed tube.
Q:The steel structure material can do
The square can be built steel shed, small steel shed are built with square, purlin is divided into 98% major plant two 4*6 and 4*8 5*10 are not a pillar or beam with the tube, because not standard
Q:How can we see is galvanized steel or wood
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.
