Promisteel Partners With Leading Jiangsu Aluminum Enterprises — Expanding Global Aluminum Supply Capability

Strong Alliance, Light Future: Promisteel Announces Strategic Partnership with Leading Jiangsu Aluminum Enterprises to Expand Global Aluminum Supply Capability

At Promisteel, our mission has always been clear - to become the preferred integrated supplier of comprehensive metal material solutions for our global customers.

This week, we are proud to share an exciting milestone: our leadership team successfully visited several major aluminum manufacturing bases in Jiangsu, China, and officially established strategic partnerships with multiple leading aluminum producers.

This collaboration marks a significant step forward in Promisteel's strategic evolution - expanding from a trusted high-quality steel supplier to a full-spectrum metal solutions partner, offering our global clients more diverse and high-performance material options than ever before.

Building a Stronger Supply Chain - Our Strategic Partnership with Jiangsu Aluminum Enterprises

1.1 The Vision Behind the Partnership

The collaboration with Jiangsu's aluminum industry was driven by the growing global demand for lightweight, high-strength materials, especially from the automotive, aerospace, construction, and electronics sectors.
Through this partnership, Promisteel is accelerating its transformation from a specialized steel supplier to an integrated metal solutions provider, capable of delivering both steel and aluminum products to meet evolving customer needs.

1.2 Rigorous Evaluation and Selection Process

Our recent visit to Jiangsu was not just symbolic - it was a technical and strategic deep dive.
We conducted comprehensive evaluations based on four key dimensions:

• Production scale and technical capability:

Our team toured advanced smelting, extrusion, and rolling lines, gaining firsthand insight into production efficiency and automation levels.

• Quality control system:

We reviewed the manufacturers' rigorous quality management systems, ensuring compliance with international standards such as ISO9001 and IATF16949.

• Innovation and R&D strength:

We were particularly impressed by the partners' investments in new aluminum alloy development and surface treatment technologies, which align with Promisteel's own commitment to innovation.

• Shared values and customer focus:

We sought partners who share our philosophy - Quality First, Customer Oriented. This cultural alignment ensures we can jointly deliver consistent excellence.

1.3 Partnership Outcomes and Customer Value

This cooperation delivers immediate and long-term value to our customers:

• Supply Security:

Our Jiangsu partners' large-scale production capacity ensures a stable and reliable aluminum supply, even under fluctuating market conditions.

• Cost and Efficiency Optimization:

By integrating upstream resources, we shorten the supply chain, offering customers more competitive pricing and faster lead times.

• Dual Quality Assurance:

Combining Promisteel's stringent service standards with our partners' advanced manufacturing expertise ensures a consistent, high-quality product experience from production to delivery.

Together, these strengths reinforce Promisteel's position as a trusted global source for both steel and aluminum materials.

Exploring New Possibilities - Our Expanded Aluminum Product Line and Applications

2.1 The Power of Aluminum

Aluminum is more than a metal - it's the foundation of the modern lightweight era.
Renowned for its low density, high strength-to-weight ratio, excellent conductivity, corrosion resistance, formability, and 100% recyclability, aluminum is the preferred material for sustainable manufacturing and green innovation worldwide.

As industries shift toward energy efficiency and environmental responsibility, the strategic importance of aluminum continues to grow - and Promisteel is ready to meet that demand.

2.2 Our Core Aluminum Products

To serve diverse industrial and commercial needs, Promisteel's aluminum portfolio includes three main product categories:

• Aluminum Plates & Coils

We supply a wide range of 5xxx and 6xxx series aluminum alloys, suitable for automotive panels, fuel tanks, building façades, packaging materials, and printing plates.
These products offer excellent mechanical strength, corrosion resistance, and surface finish - ideal for applications requiring both performance and aesthetics.

• Aluminum Profiles & Extrusions

Our standard and customized aluminum profiles are produced through high-precision extrusion and can be tailored to specific cross-sectional designs.
Applications include architectural systems (window and curtain wall frames), industrial automation (machine frames, conveyors), and renewable energy structures such as solar panel mounting systems.
With advanced die design and anodizing options, Promisteel ensures superior dimensional accuracy and durability.

• Aluminum Tubes & Bars

Promisteel's aluminum tubes and bars are widely used in machinery parts, fluid pipelines, and structural components.
These products offer outstanding machinability and are available in a variety of grades, sizes, and tempers to meet exact technical requirements.

2.3 Serving Key Global Industries

The expansion of Promisteel's aluminum supply capabilities enables us to support customers across major sectors better:

• Automotive & Transportation:

We provide solutions for vehicle lightweighting, including body panels, battery enclosures, and structural frames that enhance fuel efficiency and performance.

• Construction & Architecture:

From façades and curtain walls to ceilings and window systems, our architectural aluminum materials combine strength, beauty, and corrosion resistance for modern building design.

• Electronics & Power Engineering:

Promisteel's high-conductivity aluminum supports the production of smartphone casings, computer enclosures, power transmission cables, and heat dissipation systems.

• Aerospace & High-End Manufacturing:

We offer aerospace-grade aluminum alloys that exhibit excellent strength, fatigue resistance, and precision, meeting the stringent demands of the aviation and high-tech industries.

With this expanded lineup, Promisteel is positioned to deliver not only materials but complete metal solutions tailored to the innovation-driven needs of global manufacturers.

We warmly welcome both new and long-term partners to reach out for consultation and collaboration on our new aluminum product line.
