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.

3, Negotiable.

Q:Square steel and C steel which is better?
24 square meters, not ordinary sandwich panels, the proposed use of square tubes, want to secure a little, then use C steel, depending on how thick material and decided to require more detailed information, you can find me, I do color steel sandwich panels
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:The steel and wood preservative in the flower is how to connect
A dovetail screw / stainless steel fixed special anticorrosive wood keel screws,
Q:How the steel columns and I-beam steel structure connection?
The square column is usually connected with a connecting plate, and the upper beam is arranged on the connecting plate and is fixed by an electric welding or a bolt.
Q:The steel structure of 40*80 steel, it is tempered glass top. The steel internal fight foaming agent. But there is rust in the inner surface. Will it affect the safety? How to deal with
The rust removal on the inner wall of pipe profiles has always been a thorny problem. If the corrosion is not serious, the treatment is usually not done. If you want to anti-corrosion effect is good, but also to go inside the paint corrosion prevention practices, very few.
Q:The difference between staircase truss square steel tube and angle steel
Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. The two sides of an equal angle steel are equal in width. The specifications are expressed in millimeters of edge width * edge width * edge thickness. Such as "/ 30 x 30 x 3", that is 30 mm width equal angle, edge thickness of 3 mm. Also available models that model is the number of centimeters wide, such as angle 3#. The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#. The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
Q:25-30mm drill pipe steel, to drill a lot, need what equipment
Drill with magnetic base.Magnetic drill is also called magnetic block drill. The magnet drill is to change the electric field at the bottom of the magnetic drill after energizing. The magnetic field is absorbed on the steel structure, and then the magnetic drill motor runs at high speed to drive the drill bit and realize the drilling of the steel structure.
Q:Twist steel (twisting steel) there is no standard?
Because the steel plate for standard parts, CAD drawing without draw, only need to mark the type and size of the bearing flat steel lattice steel plate and the direction of the steel grid plate, the specific use of what types of bar, can be specified by the user, if the platform is too large, can be discharged from the layout of steel grid plate manufacturers, general row layout is free.
Q:4*4 steel welding frame tank do strong?
If you want to be firm, you can use the three and four sections. The middle slot can be clamped on the edge of the fish tank, and the tripod should be four. It's so convenient and strong!
Q:How much is the thick wall hollow square 30*30
Square: solid, bar. Different from the square pipe, hollow, belong to the pipe. Steel (Steel): material of various shapes, sizes, and properties required by pressure processing for ingots, billets, or steels.
