1. Plate Preparation:
Cutting and edge conditioning of high-quality steel plates to meet Foundation construction welded pipe standards.
2. Forming:
Roll-forming or press-bending into cylindrical shape via UOE or spiral weld methods, ensuring structural integrity for piling use.
3. Welding:
Submerged Arc Welding (SAW) for longitudinal or spiral seams—delivering deep penetration and high strength critical for Welded Structural pipe piles.
4. Sizing & Straightening:
Calibration for roundness, straightness, and dimensional consistency to ensure easy driving and splicing.
5. End Finishing:
Beveling or squaring to facilitate installation in diverse soil conditions across target regions.
6. Surface Treatment:
Optional corrosion-resistant coatings (liquid epoxy, galvanizing) to withstand marine/coastal humidity and desert erosion.
7. Quality Testing:
Non-destructive testing (ultrasonic/UT, radiographic/RT), visual inspection, and hydrostatic testing to verify compliance with ASTM A252 and API 5L standards.
8. Packaging:
Preparation for regional shipping with climate-adapted protection.
Superior Load-Bearing Capacity:
Engineered to withstand heavy axial loads and lateral forces, ideal for high-rise, bridge, and industrial foundation projects.
Durable & Corrosion-Resistant:
Marine grades (ASTM A690) and optional coatings resist coastal salt spray, tropical humidity, and desert soil erosion.
Versatile Soil Adaptability:
Performs reliably in sand, rock, clay, and wet soils across Middle East, West Asia, Africa, and Southeast Asia.
Efficient Installation:
Straightness and dimensional precision enable easy driving, splicing, and integration with construction frameworks.
Cost-Effective Foundation Solution:
As a construction steel pipe supplier, we offer durable, long-lasting piles that reduce maintenance and replacement costs.
API 5L Compatibility:
Carbon steel grades (API 5L Gr. B/X42/X52) ensure alignment with industrial and infrastructure project material standards.
Our Steel Pipe Piles comply with global and regional standards for foundation construction:

RFQ Question: Do your steel pipe piles resist desert soil erosion for high-rise foundations?
Answer: Yes, our ASTM A252 Gr. 3 high-strength piles (OD 24"-60") withstand desert erosion—with optional epoxy coating for extra protection.
RFQ Question: Need marine-grade pipe piles for coastal port construction—can they handle saltwater corrosion?
Answer: We recommend ASTM A690 marine-grade piles, engineered for saltwater corrosion resistance. They’re ideal for ports/docks, meet regional marine standards.
RFQ Question: Can you supply large diameter (60"+) steel pipe piles for industrial tank foundations in wet tropical soils?
Answer: Yes, our custom 60"-120" diameter piles (ASTM A252 Gr. 2) are designed for wet tropical soils—with thick walls (30-60mm) for stability.
RFQ Question: What grade of Welded Structural pipe piles is best for seismic-prone construction zones?
Answer: ASTM A572 high-strength steel piles offer superior ductility for seismic zones. They absorb lateral forces, meet regional structural codes, and deliver in 20-26 working days with full load capacity reports.
RFQ Question: Do your pipe piles support splicing for extra-long foundation requirements (over 24m)?
Answer: Yes, our piles are designed for secure splicing (welded/bolted) to reach 30m+ lengths. We provide splicing guidelines, use API 5L Gr. B/X42 for consistency.
