Packaging & Delivery of Structural Steel Angles

1. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

2. With bundles and load in 20 feet/40 feet container, or by bulk cargo, also we could do as customer's request.

3. Marks:

Color mark: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: There will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.

Q:Which is cheaper, angle iron and steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:What is the thickness of the national standard 8# angle steel? Thank you
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.
Q:Galvanized steel angles under what conditions?
Galvanized angle itself coated zinc and iron rust, common need to be coated with a layer of anti rust paint in the construction process, so the galvanized angle in the construction without paint. Suitable for field and outdoor support and Engineering
Q:What's the size of No. 5 angle iron?
The size of No. 5 angle steel is: steel with length, width and height of 50*50*xmm, wherein X can be 3mm, 4mm, 5mm.
Q:What does angle 5 mean?
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#.
Q:Can galvanized square tubes and angle iron be welded together?
Yes, if the requirement is not high, it can be welded directly. If the requirement is high, the zinc coating on the galvanized square pipe can be polished off before welding, and then welded. However, two kinds of welding methods, welding well, must be carried out at the weld corrosion. Now there is a special coating for hot-dip galvanizing on the market. It is characterized by high zinc content and 96% zinc content. It can provide similar anticorrosive effect to hot-dip galvanizing for repairing parts.
Q:What size does angle iron 125*10 mean?
The length should be 125mm *125mm and the wall thickness is 10mm
Q:What is the corresponding length of the root weight in the angle standard?
General fixed length delivery without weighing, no fixed length delivery is generally applied to weighing sales. Profile fixed length is generally divided into 6 meters, 9 meters and 12 meters, special sizing must be large quantities, consultation with the steel supply.
Q:How can the angle iron tripod be welded or not?
After welding a node, second nodes should select the points that are symmetrical to the main axis from the first point. The purpose is to reduce or eliminate the deformation of the point after thermal expansion,
Q:How to determine the neutral axis of the angle bar?
For the bolt group, the calculation of the location of the neutral axis is more complex, and is usually approximately assumed on the bottom row of the bolt axis.
