Applications
1. Waterfront structures
Steel sheet piling is suitable for offshore construction as it is designed to cater for heavy vertical loads and large bending moments with fast execution. Few types of retaining structures in waterfront structures are ship berthing area, wharf, breakwater and slipway.
2. Canalization
Steel sheet piling is used as the support, protection and beautification of river embankments. It can also function as flood protection wall during monsoon or high-tide season.
3. Basement
Steel sheet piling can be used for top down construction (permanent) or bottom up construction (temporary); both methods require minimal construction width offering significant time and cost savings. Steel sheet pile can also support vertical loads from the structure above.
4. Railway and Tunnel
As support structure for railway and tunnel construction, steel sheet piling helps to minimize excavation and disposal works, thus speed up the construction duration.
5. General Excavation
General excavation works involve temporary excavation for foundation construction and protection to underground structure, minimizing excavation volume and area.
6. Highway Construction
Most of the time, steel sheet piles act as retaining structure for excavation works. They can be installed easily and extracted anytime when the construction work is completed. The steel sheet piles can then be re-used and carried forward for later construction stages.
7. Bridge
Steel sheet piles can act as foundation and abutment of the bridge, requiring minimum space and construction time.
Characteristics of AU sections
A weight reduction of about 10% compared to the 600-mm PU series has been achieved by optimizing the geometric dimensions. The increased width allows faster installation, reduces the amount of coating required, due to the smaller perimeter, and increases water tightness thanks to fewer interlocks per meter of wall. Despite their greater width, the driving energy required for AU piles is no higher, thanks to their smooth and open shape and the patented radii at the web/flange connection.
Characteristics of PU sections
Equipped with reinforced shoulders, the new PU 18, PU 22 and PU 28 are the optimum choice for hard driving conditions and as a profile suitable for multiple re-use.
- Q:How to distinguish cold formed section steel and hot rolled section steel?
- Cold-formed steel is a product of various cross sections bent in cold form with steel plates or strips. Cold formed section steel is an economical light section steel, also called cold-formed steel section or cold bending section. Cold-formed steel is the main material for making light steel structures. It has various kinds of super thin and reasonable shapes and complicated sections which can not be produced by hot rolling. Compared with hot-rolled steel, in the same section area, turning radius can be increased by 50 ~ 60%, moment of inertia can be increased 0.5 ~ 3 times, so it can be more reasonable to use the strength of the material; and ordinary steel structure (from traditional I-beam, channel steel and angle steel and steel plate made of steel structure comparison) that can save steel by 30 ~ 50%.
- Q:What is special steel?
- Plough steelUsed in the manufacture of general purpose plow, plows, shallow tillage implements main plough and ordinary before plow ploughshare, general wear and has sufficient strength and toughness of the steel. China's general use of 65Mn and 65SiMnXt steel. In addition, often make tools steel and special steel shape. Such as T steel, Z steel, arc type steel, double reinforcing steel, strengthen the font, grass blade steel, flat steel and steel rod concave lines. The cold-formed steel: cold-formed steel is the main material for the production of light steel structure, made of steel or steel roll forming. It not only the wall thickness can be made very thin, but also greatly simplifies the production process, improve production efficiency, can be produced using the general method to produce uniform wall thickness and complex cross sections of various shapes and different materials of cold-formed steel cold-formed steel. Except for the building structure, but also widely used In vehicle manufacturing, agricultural machinery and so on. A lot of cold-formed steel varieties, according to the opening section, semi closed, closed. According to the shape of a cold roll, angle steel, Z steel, square tube, rectangular tube, special pipe, shutter door according to the provisions of GB6725-92, cold-formed steel with ordinary carbon negative structure and quality carbon steel, low alloy steel plate or strip made of cold-formed structure
- Q:What does "BH" mean?
- In accordance with the different smelting quality of steel, steel is divided into ordinary steel and high quality steel. According to the current catalogue of metal products, ordinary steel can be divided into large section steel, medium section steel and small section steel. The section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its sectional shape.
- Q:What does "M" mean?
- The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..
- Q:Does the profile include H?
- Another reason is that H steel is made late in our country, so people are used to distinguish it from other shapes. But in the strict sense, H steel is a kind of section bar.
- Q:Elastic modulus of section steel
- Generally speaking, the elastic body exerts an external function, and the elasticity experiences the change of the shape (called strain). The general definition of the elastic modulus is that the stress is divided by the strain. When the material is in the elastic deformation stage, its stress and strain should be changed into a positive proportion (that is to say, according to Hooke's law), and the coefficient of proportionality is called the elastic modulus.
- Q:Can the section steel butt joint in the end?
- Bolt connection also requires lining plate, pay attention to bolt size, quantity and spacing. To calculate whether thin-walled steel itself will be crushing, the solution is solder paste board, and bolt holes. The principle is that the strength of the butt joint is not weaker than that of other parts, and there is no greater stress.
- Q:What are the common types of profiled steel?
- Complex section steel has: I-beam, channel steel, steel, elevator rail, steel sheet pile, and various kinds of agricultural machinery, machinery manufacturing and construction of special-shaped steel.Section steel according to production methods are: hot-rolled steel, cold-formed steel, welding, H steel, etc.
- Q:What kind of steel is used in steel columns?
- Compared with other steel piles, steel pipe piles have their own advantages in many aspects, such as long joint welding, single pile bearing capacity, bending rigidity and penetration ability.
