Our products are not only sold in domestic market, but also exporting, we are the biggest and earliest steel structure manufacturer which doing the exporting business in North of China since 2002, until today, we have exported our products to more than 80 countries and regions all over the world. We have established strategic partnership with many foreigner customers on the basis of a long term relationship. Last year we already appear on the market which will supervised by the public. It is our great honor to establish a long term relationship with you and you could be our agent in your local place after we come to several deal if possible. Beside, we already have offices in Panama and Algeria, now we are exploring to establish more offices in more countries......

We can specializes in manufacturing customized steel components and assemblies according to clients' design specifications:

Custom Fabrication – Production of beams, columns, trusses, frames, and other structural elements tailored to project requirements.

Material Processing – Cutting, drilling, welding, bending, and shaping steel (carbon steel, stainless steel, or alloy steel).

Precision Engineering – CNC machining, laser/plasma cutting, and automated welding for high-accuracy parts.

Surface Treatment – Sandblasting, galvanizing, painting, or powder coating for corrosion resistance and aesthetics.

Assembly & Welding – Sub-assembly or full structural integration with certified welding techniques (CWA, ISO standards).

Quality Control – Non-destructive testing (NDT), dimensional inspections, and compliance with international standards ( GB, ASTM, EN).

1. Technology R&D Direction

Application of High-Performance Materials

Develop weathering steel, high-strength steel (such as Q460 and above) and fire-resistant steel to adapt to extreme climates (such as high temperatures in the Middle East and low temperatures in Northern Europe).

Explore composite materials (such as steel-aluminum, steel-glass fiber hybrid structures) to reduce weight and maintain strength.

Node Optimization and Modular Design

Develop standardized bolted connection nodes to reduce reliance on on-site welding (such as the EN 1090 certification requirements of the European specification).

Modular design facilitates transportation and rapid installation (such as prefabricated steel structure houses, detachable exhibition halls).

Digitalization and Intelligence

Apply BIM (Building Information Modeling) for collaborative design to reduce design conflicts.

Use parametric design tools (such as Grasshopper) to optimize special-shaped structures (such as curved grids).

2. Experimental Verification System

Material Performance Testing

Tensile, impact, and hardness tests (ASTM A370, ISO 6892) to ensure that the materials meet American standards (ASTM), European standards (EN) or added standards (CWB).

Corrosion resistance test (Salt spray test ASTM B117) for marine environment projects.

Structural load test

Static load/dynamic load test (such as ISO 8980), simulated earthquake and wind load (such as US IBC specification requirements).

Fatigue test (such as EN 1993-1-9) verifies the long-term reliability of bridges and high-rise building components.

Fire protection and earthquake resistance special

Fire retardant coating performance test (UL 1709 standard, requiring 90 minutes fire resistance limit).

Vibration table test simulates seismic waves (meets US AISC 341 earthquake resistance specification).

3. International certification and standardization

Certification acquisition

EU CE certification (EN 1090-1/2), US AISC certification, Middle East SASO certification.

Welding procedure qualification (WPS/PQR) complies with AWS D1.1 or ISO 3834.

4. Market-oriented R&D strategy

Regional customization

Middle East: Focus on anti-sand and high-temperature resistant coatings; Southeast Asia: Typhoon-resistant design (wind pressure coefficient ≥ 1.5).

Europe: Low-carbon steel (in line with the carbon footprint requirements of EU Green Deal).

Rapid response capability

Complete routine project processing within 3-4 weeks

5. Typical case reference

Successful application

An airport terminal in Uruguay: Use high-strength steel (yield strength 460MPa) + modular installation to shorten the construction period by 40%.
