Equipped with CNC cutting machines, robotic welding stations, and automated processing lines, our facility ensures each product is manufactured with precision and meets the highest international standards.

Global Certifications & Quality Control

At USP, quality is at the core of everything we do. We operate under a strict quality management system and are certified to ISO 9001, EN 1090-2 (welding of structural components), and ISO 3834 (welding quality assurance). All welding procedures undergo strict qualification processes, and our welders are certified to AWS and AS/NZS standards to ensure the highest level of craftsmanship.

Advanced Manufacturing Facilities

Our production base is equipped with cutting-edge fabrication and inspection tools, including:

• CNC machining systems
• Robotic welding stations
• Large-scale steel processing equipment
• Sandblasting and coating lines

We also maintain in-house non-destructive testing (NDT) and pressure testing capabilities to ensure that every product meets the strictest standards of quality and safety.

High-Strength Steel Expertise

USP is highly experienced in high-strength structural steel fabrication, suitable for components subject to heavy loads or extreme environments. We work with globally recognized materials—including high-strength steel, alloy steel, and others—to deliver durable, high-performance structural components for mining, metallurgy, and energy projects.

Environmental & Safety Commitment

As a sustainability-focused company, USP is certified to ISO 14001 for environmental management and ISO 45001 for occupational health and safety. We apply eco-friendly surface treatment processes and optimized waste management systems to minimize environmental impact while ensuring a safe and healthy workplace for all personnel.

Capacity & Materials

USP’s monthly production capacity for structural steel ranges from 800 to 1,000 tons, supporting large-scale and time-sensitive projects. We source and work with a wide range of international material standards, including:

• GB (China National Standards)
• ASTM (American Standards)
• EN (European Standards)
• JIS (Japanese Standards)
• As well as client-specified specifications

Our material portfolio includes carbon steel, low-temperature steel, stainless steel, and alloy steel, ensuring optimal performance and durability across a range of working conditions.

Fabrication Scope

USP’s comprehensive fabrication capabilities cover a wide range of complex and large-scale structural applications, including:

• Industrial Structures: Custom structural steel systems for power plants, oil & gas facilities, mining operations, chemical plants, and industrial buildings. Engineered for strength, corrosion resistance, and thermal stability.
• Conveyor Frames: Durable steel structures for conveyors used in logistics, mining, and metallurgy, built to perform under heavy operational loads.
• Base Frames: Heavy-duty base structures for large machinery and installations, designed for long service life and optimal load-bearing.
• Plate Structures: We fabricate custom plate components including support plates, platforms, and protective panels used in building and equipment foundations.

In addition to conventional supports, platforms, and stairways, we also offer fully custom-designed structures based on client specifications to meet unique project requirements.

Fabrication Technology

We employ advanced manufacturing techniques such as high-precision CNC cutting, automated welding, and thermal treatment, ensuring consistency and quality across all components. Our fully integrated production lines are equipped with robotic welding and precision machining systems, capable of delivering complex fabrications at scale.

All production processes are governed by ISO 9001 standards and validated through welding procedure qualificationand NACE-certified inspections, guaranteeing long-term reliability and performance.
