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: What does "M" mean?
- M section steel: sectional shape steel like M.
- 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: 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: Elastic modulus of section steel
- The elastic modulus of steel is 2.1 * 10^7N/cm L.
- Q: What kind of steel is used in steel columns?
- Section I and H of steel reinforced piles belong to the common section shapes in steel reinforced concrete piles. I and H type steel piles can be used in horizontal load and vertical load bearing. The steel pile has stronger penetration ability in many kinds of strata, moreover, its disturbance to stratum is slight, it is a kind of partly squeezed soil pile. If the distance between the driving pile and the center is smaller, the H steel pile can be used to replace other piles to prevent the ground fault caused by piling operation, such as lateral extrusion, uplift and so on.
- Q: What is special steel?
- Military materialsOther varieties are mainly some special quality profiles. Including hollow steel, oxygen bottles, industrial pure iron, hot rolling, cold heading steel easy to cut steel, D60, S/5A, F18, F11 etc., behind several are. High quality steel is not large, medium and small, round and Fang Gang divided into groups according to specifications from, such as 8-10mm, 11-15mm, 18-20mm, 205-245mm. flat area by large, medium and small flat. Six angle distance is not grouped. But the quality of steel group distance is no substitute for detailed specifications, in the document should be filled concrete specifications. Quality profile specification is simple, the vast majority of round steel. In addition, flat steel, and Fang Gang six chest steel, hollow steel, shaped and so on hot rolling (forging) size deviation of high-quality steel, Fang Gang, the six angle of the ordinary high accuracy and precision of two. And has a more precise cold drawn profile surface size and smooth surface polishing, polishing, but also some After polishing or round processing. The polished surface is exquisite, called steel. High quality profiles are rarely used, mostly through the use of the unit for further processing and after heat treatment, therefore, in addition to chemical composition, but also to ensure the mechanical properties after heat treatment.
- Q: Can the section steel butt joint in the end?
- Docking is usually available.If welding, it is mainly worried that the welding is not strong and the welding stress is too large. The wall thickness of the section steel is thin, and the butt welding itself is the most unreliable. So, in the joint lining board, fillet welded. Attention is paid to reducing stress in the process.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.In short, 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?
- Section steel is divided into two types: simple section steel and complex section steel.Simple section steel: steel, wire rod, square steel, flat steel, six angle steel, triangular, elliptical steel, steel arch steel, etc..
- 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%.
