Click the Button on The Right
1. Building Foundation (Deep Foundation Systems)
Used as deep foundation piles for high-rise buildings, industrial factories, logistics warehouses, commercial complexes, and residential structures. These steel pipe piles provide strong vertical load-bearing capacity and ensure long-term structural stability in weak or soft soil conditions.
2. Bridge Foundation Engineering
Ideal for highway bridges, railway bridges, urban elevated roads, and overpass structures. ASTM A252 LSAW / EFW steel piles are widely used in river-crossing, lake-crossing, and sea-crossing bridge foundations, offering excellent resistance to dynamic loads and soil movement.
3. Port and Marine Construction
Applied in port terminals, container yards, shipyards, dock platforms, and offshore loading facilities. These steel pipe piles are designed to support heavy cranes, cargo handling systems, and large-scale marine infrastructure with high durability in corrosive coastal environments.
4. Offshore Wind Power & Marine Engineering
Widely used in offshore wind turbine foundations, offshore platforms, marine pipelines, seawalls, and coastal protection structures. The LSAW steel pipe piles provide excellent resistance to wave impact, tidal forces, and seawater corrosion, making them suitable for harsh offshore environments.
5. Large-Scale Civil Engineering Projects
Used in dams, underground metro stations, tunnels, retaining structures, and large infrastructure projects requiring deep foundation support. These piles are capable of carrying heavy industrial equipment loads and complex structural stress conditions.
1) Branch Office - Spanish-speaking support, customs clearance assistance, etc.
2) Over 5,000 tons of stock in stock, with a wide variety of sizes
3) Inspected by authoritative organizations such as CCIC, SGS, BV, and TUV, with standard seaworthy packaging
1 Packaging: Steel banding for handling ease. Wooden blocks or dunnage is placed between the stacks to avoid organ shift during transportation. Surface treatment (optional): Black painting, rust preventive oil, plastic film. Hot-dip galvanized piles may be coated with a temporary protective film to avoid scratches in the surface. Customized packaging can be provided.
2 Delivery: Common stock lengths: 6m , 12m. Available in custom lengths. Come with Sea Rail and Road Applicable Suitable for sea, rail or road transport. The delivery time is usually 15-30 days upon receipt of payment, subject to quantity and specification. Suitable for worldwide export, with complete document (inspection certificate, packing list, bill of lading).
3 Precautions for handling: Do not use slings or hooks without pads to act directly upon the pipe surface to avoid the pipe being deformed. Keep in a cool, dry and well-ventilated place, avoid rust before install. Over sized and over weight shipment please comply with local shipping regulations.
1. ASTM A252 Grade 3 steel pipe applications?
ASTM A252 Grade 3 LSAW steel pipes are primarily applied for the deep foundation piling in construction works, such as buildings, bridges, ports, offshore and so on.
2. How are Grade 1, Grade 2 and Grade 3 different?
It offers the best strength and stability of 3 grades, so is ideal for heavy-load foundations, and marine engineering.
3. What is LSAW steel tube?
Adapted from the expert knowledge of steels, LSAW pipe is a pipe product that is manufactured by forming and longitudinal welding steel plates, which is also called “longitudinal weld steel pipe”.
4. What sizes and thicknesses are available?
The available diameters 2 ranges in size from OD 406 mm to 2500 mm and wall thickness ranges from 6 mm to 60 mm applicable for heavy foundation and marine construction works.
5. Can it be used in marine and offshore projects?
Yes. It is commonly used in offshore wind power, seawalls, docks, and marine platforms, among others. It has coatings including epoxy, 3PE, cement mortar for anti-corrosion.
